Understanding Wood Stain Spray Technology for Large Projects
The Science Behind Aerosol Stain Formulations
Modern wood stain sprays represent a sophisticated balance of chemistry and engineering. Unlike traditional canned stains that rely on manual agitation and application pressure, aerosol formulations contain propellant systems that atomize the stain into precisely controlled droplet sizes—typically ranging from 20 to 100 microns. This micronization determines how the stain interacts with wood grain, with finer mists penetrating dense hardwoods more uniformly while larger droplets work efficiently on porous softwoods. The formulation itself must maintain stability under pressure, resisting separation of pigments, binders, and solvents for months on the shelf.
Why Spray Application Excels on Large Surfaces
The mathematics of coverage reveals why sprays dominate large projects. A standard brush applies stain at roughly 2-3 square feet per minute, while a quality spray system can cover 40-60 square feet in the same timeframe. More importantly, sprays eliminate the “fat edge” problem where brush strokes accumulate excess material at stroke boundaries. On expansive surfaces like privacy fences or commercial siding, this translates to zero lap marks and consistent color depth from end to end. The aerosol mist also reaches into microscopic wood fissures that brushes simply cannot access, creating a more durable, weather-resistant finish.
Key Features That Define Premium Wood Stain Sprays
Viscosity and Flow Characteristics
The ideal spray stain viscosity falls between 15-25 seconds on a Zahn cup #2 scale—thin enough to atomize cleanly but substantial enough to carry adequate pigment load. Premium formulations include thixotropic agents that temporarily thin under shear pressure (when spraying) then regain body upon contacting the wood surface. This prevents excessive penetration on softwoods while ensuring adequate flow on dense grains. For large surfaces, this balance is critical; too thin and you’ll need four coats, too thick and you’ll face clogging and orange peel texture.
Nozzle Technology and Spray Patterns
Look for adjustable fan-pattern nozzles that can pivot from a 6-inch concentrated stream to a 12-inch oval fan without changing cans. The best systems use two-stage atomization: first breaking the stain into primary droplets, then using secondary air jets to refine the pattern. For vertical surfaces like siding, a horizontal fan pattern minimizes runs by distributing material in overlapping bands. Some advanced nozzles incorporate anti-drip technology that retracts the stem after each trigger release, preventing the messy spitting common with cheaper cans when you pause.
Drying Time and Workability Balance
Large surface projects require what finishers call “open time”—the window between application and when the stain becomes tacky. Premium spray stains offer 5-8 minutes of open time in 70°F conditions, allowing you to maintain a wet edge across a 10-foot section. However, they also contain fast-evaporating solvents that lock the pigment within 30 minutes to prevent redistribution. This dual-phase drying is achieved through solvent blends: slower glycol ethers for workability, faster acetates or alcohols for initial set.
Types of Wood Stain Sprays: Which Formula Works Best?
Oil-Based Stain Sprays: Deep Penetration Benefits
Oil-based aerosol stains utilize alkyd or linseed oil vehicles that penetrate up to 1/8-inch into most woods, carrying pigments deep into the cellular structure. This creates exceptional UV resistance and moisture protection—critical for exterior decks and fences. The trade-off is 24-48 hour drying times and strong VOC emissions. For large surfaces, their slower drying actually becomes an advantage, allowing you to correct mistakes and blend sections seamlessly. They excel on weathered wood because the oils rejuvenate dried fibers while staining.
Water-Based Stain Sprays: Eco-Friendly Advantages
Waterborne formulations have evolved dramatically, now offering performance that rivals oil-based products with 2-4 hour drying times and soap-and-water cleanup. They use acrylic or polyurethane dispersions that form a micro-thin film on wood surfaces while allowing some pigment penetration. For interior large surfaces like paneling or floors, their low odor is invaluable. The key specification is the resin solids content—look for 25-30% for adequate durability without creating a plastic-like film that obscures grain.
Hybrid and Gel-Based Spray Stains
Emerging hybrid formulas combine oil penetration with water cleanup through proprietary emulsion technology. These are game-changers for large projects where you need performance without solvent headaches. Gel-based sprays, which dispense a thixotropic gel that self-levels, virtually eliminate runs on vertical surfaces. They’re ideal for rough-sawn cedar or textured surfaces where liquid stains would pool unpredictably. The viscosity requires specialized nozzles with larger orifices, so ensure compatibility before purchasing.
Surface Preparation: The Foundation of Flawless Coverage
Cleaning and Degreasing Protocols
Large surfaces accumulate invisible contaminants that cause fisheyes and poor adhesion. Use a two-step cleaning process: first, pressure wash with a wood-specific detergent containing sodium metasilicate to neutralize acids and remove grayed fibers. Follow with a brightener containing oxalic acid to restore pH balance and open grain structure. For interior surfaces, TSP substitutes work well, but rinse thoroughly. The wood must dry to 15% moisture content or less—use a pinless moisture meter to verify across multiple locations on large surfaces.
Sanding Strategies for Large Areas
Random orbital sanders with 80-grit paper create the ideal abrasion pattern for stain adhesion, but on vast expanses, this becomes impractical. Instead, use a floor buffer with a sanding screen for horizontal surfaces, or a drywall sanding pole with 120-grit for vertical work. The goal isn’t glass-smoothness but rather uniform scratch pattern. Always sand in the direction of the grain, and stop when the surface feels uniformly smooth to the touch. Never skip sanding old stain remnants; they create penetration barriers that show as ghost lines after spraying.
Wood Moisture Content Considerations
Wood is hygroscopic, and large surfaces can have significant moisture variation. Spray stain when the wood is within 5% of its equilibrium moisture content (EMC) for your climate. In most regions, this means 9-14% for exterior wood. Staining wood that’s too wet traps moisture, leading to premature peeling and mold. Conversely, extremely dry wood (below 8%) absorbs stain too rapidly, causing a blotchy appearance. For new lumber, allow 2-4 weeks of acclimation, stickered for air circulation.
Application Techniques for Professional Results
The Overlapping Pass Method
The secret to invisible transitions is the 50% overlap rule. Each spray pass should cover half of the previous wet edge, creating a continuous film that blends seamlessly. Move at a consistent 6-8 inches per second, maintaining 10-12 inches distance from the surface. On large horizontal surfaces like decks, work in 3-foot wide corridors running the length of the boards, not across them. This follows the wood’s natural grain direction and prevents cross-grain lap lines that catch light.
Managing Overspray and Edge Control
Overspray is the nemesis of large projects, drifting onto windows, plants, or adjacent surfaces. Create a “spray shadow” by positioning a 4x8 foot sheet of cardboard or plywood vertically along the edge you’re staining. Spray toward this shield, which captures airborne particles while allowing you to fully cover the wood edge. For intricate areas, use painter’s tape with plastic film that unfolds to cover wide areas quickly. Indoors, box fans with furnace filters can create negative pressure to contain overspray.
Multi-Directional Spraying for Uniformity
Wood grain isn’t uniform, and neither should your spray pattern be. After completing your primary passes with the grain, make one final light “cross-hatch” pass at 45-degree angles. This ensures stain reaches side-grain areas and compensates for any slight variations in spray density. The key is using only 30% of your normal material volume for this pass—think of it as a dusting that evens out the appearance without creating runs. On textured surfaces like rough-sawn fascia, this technique is non-negotiable.
Environmental Factors That Impact Spray Performance
Temperature and Humidity Guidelines
The sweet spot for spray stain application is 60-80°F with relative humidity between 40-60%. Below 50°F, drying slows dramatically and propellant pressure drops, causing sputtering. Above 90°F, stains flash-dry before leveling, creating texture. High humidity (over 70%) introduces moisture into the spray pattern, causing blushing—a milky appearance from trapped water. Use a hygrometer to monitor conditions, and schedule large projects for mid-morning when dew has evaporated but afternoon heat hasn’t peaked.
Wind Management for Outdoor Projects
Even a 5 mph breeze can deflect spray particles, causing 30% material loss and uneven deposition. For exterior large surfaces, create windbreaks using temporary fencing or tarps. Work on the leeward side of structures when possible. Early morning typically offers the calmest conditions. If you must work in wind, switch to a narrower spray pattern and move closer to the surface (8 inches instead of 12), accepting that progress will be slower but more precise.
Indoor Ventilation Requirements
Interior large surfaces like ceilings or wall paneling require aggressive ventilation to remove solvents and overspray. Use a two-fan system: one exhaust fan in a window pulling air out, and a second fan on the opposite side drawing fresh air in. This creates a laminar flow that carries overspray away from your work area. For water-based stains, aim for 4-6 air changes per hour; for oil-based, 10-12 changes. Never recirculate air—overspray particles will redeposit on wet surfaces as dust.
Equipment Beyond the Can: Essential Accessories
Extension Wands and Spray Shields
For overhead work or ground-level decking, a 24-36 inch extension wand saves your back and ensures consistent distance from the surface. Look for wands with adjustable angle heads to spray upward on fascia boards without contorting. Spray shields—essentially large putty knives with absorbent foam edges—allow you to cut clean lines where stain meets trim or siding. The foam catches overspray while the rigid blade protects the adjacent surface.
Protective Masking Solutions
Standard painter’s tape fails on large-scale masking jobs. Instead, use a masking machine that simultaneously applies tape and unfolds plastic sheeting in widths up to 99 inches. For delicate surfaces like stone or brick, use low-tack tape with a “edge sealer” liquid that prevents stain from bleeding underneath. On windows, apply liquid masking film that you paint on and peel off later—it conforms to muntins and handles better than plastic on large glass areas.
Lighting for Inspection
You can’t fix what you can’t see. For large interior surfaces, use 500-watt halogen work lights positioned at a low angle (raking light) to highlight imperfections, dry spots, or runs while you work. Outdoors, schedule staining so the sun is behind you, illuminating the surface uniformly. Avoid working in direct overhead sunlight, which creates harsh shadows and makes wet stain difficult to see. LED headlamps with adjustable color temperature help you match color consistency across different lighting conditions.
Troubleshooting Common Spray Stain Issues
Blotching and Uneven Absorption
Blotching occurs when wood density varies across large surfaces, causing some areas to absorb more stain. The solution isn’t in the spray technique but in pre-treatment. Apply a thin wash coat of dewaxed shellac (1 lb. cut) or a commercial pre-stain conditioner before spraying. This partially seals absorbent grain, creating a more uniform substrate. For severe cases on pine or maple, spray the stain, let it sit for 2 minutes, then lightly wipe with a large applicator pad to redistribute excess pigment from dense areas to porous ones.
Runs, Drips, and Sagging Prevention
On vertical large surfaces, runs are the primary enemy. The cause is almost always excessive material application. If you notice a run forming, don’t panic—immediately spray a dry pass (no trigger pull) over the area. The moving air stream will partially dry the surface and halt the run’s progress. For prevention, apply multiple thin “tack coats” rather than one heavy wet coat. A tack coat dries in 3-5 minutes and provides tooth for subsequent layers, allowing you to build color depth without gravity working against you.
Color Inconsistency Across Large Surfaces
Color drift happens when spray cans from different production batches are used, or when environmental conditions change mid-project. Always purchase 20% more stain than calculated, and ensure all cans share the same batch number (printed on the can bottom). Mix cans together in a larger container for uniformity, then use a refillable spray system if possible. If you must switch batches, create a blending zone in a less conspicuous area, like behind a downspout or in a corner, spraying a 50/50 mix from both batches across a 4-foot transition area.
Comparing Spray vs. Traditional Application Methods
Time Efficiency Analysis
A professional can spray stain on a 1,000-square-foot deck in 45 minutes, while brushing would take 6-8 hours. But time savings extend beyond application. Sprays eliminate brush cleaning (30 minutes), reduce masking time because of precision nozzles, and cut drying time between coats since thinner films are applied. The real metric is “project completion time”—what takes two weekends with brushes often finishes in one afternoon with sprays, factoring in weather windows and cure times.
Cost-Per-Square-Foot Considerations
At face value, spray stains cost 2-3 times more per ounce than liquid stains. However, the total project cost often favors sprays on large surfaces when you factor in labor and waste. Brushes and rollers absorb 10-15% of product that never transfers to wood. Sprays deliver 85-90% transfer efficiency. For DIYers, the value proposition is time saved; for professionals, it’s the ability to complete more jobs per season. The break-even point is typically around 200 square feet—below that, brushes may be more economical.
Finish Quality Differences
Spray application creates a micro-thin, uniform film that highlights wood grain without building surface texture. Brushes, even high-quality ones, leave subtle texture from bristle marks that can obscure fine grain on large surfaces where light rakes across the plane. However, sprays require more skill to avoid the “plastic” look that comes from excessive build. The sweet spot is often a hybrid approach: spray for base color, then lightly brush or wipe to integrate the stain and soften any spray texture.
Safety Protocols and Protective Measures
Respiratory Protection Standards
Oil-based spray stains generate respirable particulates down to 10 microns that bypass natural filtration. Use a NIOSH-approved respirator with organic vapor cartridges and P100 particulate filters—not just a dust mask. For large projects lasting several hours, consider a supplied-air respirator (SAR) that delivers clean air from a remote compressor. Change cartridges when you first detect odor; by then, you’ve already been exposed. Keep a spare set on hand for every 4 hours of continuous spraying.
Skin and Eye Safety
Stain propellants can force pigment deep into skin pores, causing staining that lasts weeks and potential chemical absorption. Wear nitrile gloves (not latex, which degrades with solvents) and a full-face shield, not just safety glasses. Cover all exposed skin with a disposable Tyvek suit on large projects. The suit also prevents overspray from embedding in clothing fibers, which can later transfer to other surfaces. If stain contacts skin, remove immediately with mineral spirits, then wash with soap and water—don’t let it sit.
VOC Regulations and Compliance
Federal VOC limits for stains are 250 g/L, but many states (notably California and New York) enforce stricter 100 g/L standards. Using non-compliant products on large surfaces can trigger significant fines, especially for contractors. Water-based sprays typically meet all regulations, while some oil-based formulas are restricted. Always check the product’s VOC content on the technical data sheet, not just the marketing claims. For interior large projects, consider zero-VOC formulations that use exempt solvents like acetone or tertiary butyl acetate.
Project Planning and Coverage Calculations
Estimating Material Needs
Coverage claims on cans (e.g., “covers 75 sq ft”) assume ideal conditions on smooth wood. For rough-sawn surfaces, multiply your square footage by 1.5. For weathered or porous wood, use a 2x multiplier. A simple formula: (Total Square Feet × Wood Factor) ÷ Can Coverage × 1.2 (waste factor) = Cans Needed. For example, a 400 sq ft deck of weathered cedar: (400 × 2) ÷ 75 × 1.2 = 12.8 cans—round up to 13. Always round up, not down; running out mid-project creates visible lines.
Staging Large Surface Areas
Divide vast surfaces into manageable zones based on natural breaks in the architecture—corners, trim pieces, or support posts. Each zone should be completable within the stain’s open time (typically 10 minutes). Mark these zones with painter’s tape on the ground or adjacent surfaces as visual guides. Work systematically, completing one zone before moving to the next. This prevents the chaotic “jump around” approach that leads to missed spots and overlap errors that become apparent only after drying.
Scheduling for Optimal Drying Conditions
Large surfaces require careful timing. Plan to start after morning dew evaporates (typically 10 AM) but finish at least 2 hours before evening dew formation. For oil-based stains, this means completing application by 3 PM in many climates. Track the weather forecast for 48 hours post-application; rain can ruin uncured stain. Create a contingency plan: have tarps ready to cover the surface if unexpected weather moves in, but never cover tightly—trapped moisture causes hazing.
Maintenance and Long-Term Care
Cleaning and Storage of Unused Product
Partially used cans often fail to spray months later because propellant leaks or pigment settles into a solid mass. After each use, clear the nozzle by turning the can upside down and spraying until only propellant emerges. Store cans in a climate-controlled space; temperature swings below 40°F or above 90°F degrade propellant pressure and resin stability. For large projects with multiple cans, invest in a refillable spray system where you transfer stain to a reusable vessel—this eliminates can wastage and ensures consistent pressure throughout the job.
Touch-Up Techniques
Large surfaces inevitably need touch-ups from wear or damage. The challenge is blending new spray with aged stain. First, clean the area thoroughly and lightly scuff with 220-grit sandpaper. Spray a test card and compare it to the faded stain; colors shift as they age, often lightening and warming. You may need to intermix stains to match. Apply thin tack coats, feathering 6-12 inches beyond the repair area. Immediately after spraying, use a dry brush to soften the transition zone, pulling pigment from the wet repair into the surrounding area.
Protective Topcoat Selection
Stain alone provides minimal protection; topcoats are essential for large surfaces exposed to wear. For sprayed stain, the topcoat must be thin enough not to obscure the grain but durable enough for traffic. Water-based polyurethane in a satin sheen works well—spray it using the same equipment for consistency. Apply 2-3 thin coats, sanding with 320-grit between applications. For exterior projects, consider a penetrating oil topcoat that can be sprayed and wiped, maintaining the natural feel while adding water repellency.
Environmental and Health Considerations
Low-VOC and Zero-VOC Formulations
The shift toward environmentally conscious products has spawned genuinely effective low-VOC sprays. These use high-molecular-weight resins that don’t evaporate as readily, reducing emissions without sacrificing performance. Look for Green Seal or Master Painters Institute (MPI) certification, which verifies both VOC content and performance standards. For interior large projects, zero-VOC products eliminate the need for extended ventilation periods, allowing reoccupation within hours rather than days.
Disposal Best Practices
Never dispose of partially filled aerosol cans in regular trash—the propellant makes them hazardous. Completely empty the can by spraying until no product remains, then puncture the can (using a commercial puncturing device) to release residual pressure. Many municipalities accept punctured, empty cans in recycling. For unused liquid stain, treat it as household hazardous waste. Never pour it down drains or onto soil. On large projects, calculate carefully to minimize waste; that extra can you bought for insurance is better used for touch-ups than discarded.
Sustainable Wood Staining Alternatives
Emerging bio-based stains use renewable resources like soy, linseed, and cashew nut shell liquid as carriers. These products offer carbon-neutral benefits and often superior penetration on large surfaces because their molecular structure mimics natural wood oils. While currently premium-priced, they deliver exceptional results on cedar and redwood, woods that naturally resist petrochemical stains. Some formulations are even compostable, addressing end-of-life environmental concerns that traditional stains create.
Cost Analysis and Value Proposition
Price vs. Performance Metrics
Budget spray stains ($5-8 per can) often contain 30% less pigment and use lower-grade propellants that sputter. Premium options ($12-18 per can) deliver higher solids content, better nozzles, and batch consistency that’s crucial for large surfaces. The cost difference per square foot is minimal—perhaps $0.15 vs $0.22—but the labor savings from fewer coats and touch-ups make premium products the economical choice. Calculate total project cost including your time at $25/hour; suddenly that $10 can that saves two hours is a bargain.
Bulk Purchasing Strategies
For projects exceeding 20 cans, contact manufacturers directly or through professional paint suppliers. Many offer case discounts (10-15% off) and can guarantee same-batch production runs. Some suppliers provide “contractor packs” with matched nozzles and technical support. Store excess cans properly; the savings evaporate if product degrades before use. For recurring large projects, establish a relationship with a supplier who can hold inventory and provide consistent product from stored batches.
Warranty and Manufacturer Support
Reputable manufacturers offer technical data sheets detailing coverage, drying times, and compatibility—essential for large project planning. Some provide warranties against premature failure when their products are applied according to specifications. This is particularly valuable for contractors staining large exterior surfaces. Keep purchase receipts and document application conditions; warranty claims require proof of proper use. Manufacturers may also offer on-site consultation for projects exceeding a certain size, helping you avoid costly mistakes.
Professional Tips for Challenging Scenarios
Spraying Vertical Surfaces
Gravity is your adversary on walls and fences. The professional approach is “bottom-to-top” spraying, which sounds counterintuitive but prevents runs. Start at the bottom, applying a light tack coat. Move upward, with each subsequent pass overlapping the previous one. The tack coat at the bottom catches any drips from above, while the upward motion ensures you see and correct runs immediately. On tall surfaces, use scaffolding rather than ladders—it provides stable footing for consistent spray distance and reduces fatigue that leads to technique errors.
Staining Overhead Areas
Ceilings and soffits present unique challenges: overspray rains down on you, and maintaining distance is awkward. Wear a full hooded suit and position a large piece of cardboard below your work area to catch falling overspray. Use an extension wand with a 45-degree angled nozzle, allowing you to stand comfortably while spraying upward. Apply extremely thin coats—70% of your normal volume—and plan for three coats instead of two. The reduced volume prevents sagging despite gravity’s assistance.
Working with Difficult Wood Species
Exotic woods like ipe or teak contain natural oils that resist most stains. On large surfaces of these species, prep is everything. Wipe the entire surface with acetone 30 minutes before staining to remove surface oils and open the grain. Use oil-based stains exclusively, as water-based products bead up. Apply in very thin, multiple passes, allowing 15 minutes between coats for the wood to accept the stain. Test in an inconspicuous area first; some tropical woods require specialized formulations designed for high oil content.
Frequently Asked Questions
What makes a wood stain spray suitable for large surfaces versus small projects?
Large-surface sprays feature higher propellant pressure for extended reach, adjustable fan patterns up to 12 inches wide, and slower-drying formulations that maintain a wet edge across broad areas. They also contain anti-clogging agents that prevent nozzle failure mid-project, which is critical when you’re 200 square feet into a fence and can’t afford interruptions.
How do I calculate exactly how many cans I’ll need for my deck or fence?
Measure your total square footage, then multiply by a wood texture factor (1.0 for smooth, 1.5 for rough-sawn, 2.0 for weathered). Divide by the can’s coverage rate (usually 60-80 sq ft per can), then add a 20% waste factor. For a 300 sq ft rough-sawn fence: 300 × 1.5 = 450 sq ft; 450 ÷ 75 = 6 cans; 6 × 1.2 = 7.2 cans—round up to 8 for safety.
Can I use interior wood stain spray for an exterior project if it’s all I have?
No—interior formulations lack UV inhibitors and fungicides that protect against sun and moisture damage. Using interior stain outside will result in fading within months and potential mold growth. The resin systems are also not designed for thermal cycling, leading to cracking and peeling. Always use products specifically labeled for exterior use on outdoor large surfaces.
What’s the ideal weather window for spraying a large exterior surface?
Target a 48-hour period with temperatures between 60-80°F, humidity below 60%, and no precipitation. Wind should be under 5 mph. Check the forecast for the day of application plus the next day, as most stains require 24 hours before water exposure. Morning applications (10 AM start) typically offer the most stable conditions.
How do I prevent lap marks when I need to stop and start on a large project?
Work in defined zones that match the stain’s open time—typically 10-minute sections. When you must stop, do so at a natural break like a corner, post, or board joint. If you must stop mid-surface, feather your stopping edge by reducing spray volume and moving faster over the last 12 inches. When resuming, start 6 inches before the stopped area with a light tack coat to blend.
Is it better to spray stain on horizontal or vertical surfaces first?
Always stain vertical surfaces first. Any overspray that lands on horizontal areas below will be covered when you stain those surfaces later. This sequence prevents having to re-mask and protects your finished horizontal work. Work top-to-bottom on verticals, then complete horizontals last, moving systematically across the area.
Can I thin a wood stain spray if it’s too thick or if I want a lighter color?
Never thin aerosol stains—adding solvent disrupts the carefully balanced propellant-to-product ratio, causing sputtering and inconsistent spray patterns. For a lighter color, instead spray a light “dusting” coat and immediately wipe with a clean cloth to remove excess pigment. Or purchase a lighter shade and blend by spraying alternating passes. Thinning also voids warranties and can create hazardous overspray that travels farther.
How do I handle spray stain that accidentally gets on plants or grass?
Immediately flush vegetation with copious water—at least 5 gallons per square foot of overspray area. For oil-based stains, you may need to apply a horticultural detergent to break down the oil. Cover plants with damp burlap before spraying as prevention. Most stains won’t kill established plants but can damage new growth. If concerned, trim affected leaves after the incident; plants typically recover quickly with proper watering.
What’s the difference between a “stain and sealer” spray and a standalone stain?
Stain-and-sealer combos contain film-forming resins that create a protective layer, while standalone stains penetrate without significant surface film. For large horizontal surfaces like decks, the combo product saves a step but may wear unevenly, requiring complete stripping later. Standalone stains with a separate topcoat offer better long-term maintenance—you can recoat just the topcoat as it wears without disturbing the color layer.
How long should I wait before applying a second coat or topcoat over sprayed stain?
For water-based stains, wait 2-4 hours or until the surface is dry to the touch and no longer cool-feeling, indicating evaporative cooling has stopped. Oil-based stains require 24-48 hours depending on temperature and humidity. Test by pressing a cotton ball onto an inconspicuous area—if fibers stick, it’s not ready. Rushing the recoat window traps solvents, causing softness and adhesion failure. On large surfaces, use a moisture meter set to wood mode; readings should be consistent with ambient conditions before topcoating.
