Deck & Fence Staining
Frequently Asked Questions
General Questions
Staining protects your wood from the number one causes of deck and fence replacement: rotting and warped wood. A quality stain enhances the wood grain, provides UV protection to prevent graying, and a good sealant penetrates deep into the wood to act as a conditioner while preventing moisture damage. Without proper protection, UV rays turn wood gray and moisture causes warping, cracking, and rot.
You can expect to re-stain your deck every 2-3 years, though this can range from 2-5 years depending on several factors including foot traffic, sun exposure, and the type of stain used. Oil-based penetrating stains typically need maintenance every 2-3 years. High-traffic areas like steps or areas near doors may wear faster. Regular annual washing with a diluted bleach solution can help extend the life of your stain by keeping organic growth under control.
Professional staining ensures proper preparation, even application, and long-lasting results backed by warranties. Professionals have the right tools, experience with different wood types and conditions, and knowledge of proper techniques. However, DIY is possible if you have the time to properly prepare the surface (cleaning, stripping, sanding) and follow best practices for application. Inexperienced stainers often leave behind uneven coating, stain where it shouldn’t be, or inconsistent lines.
Choosing the Right Stain Type
Water-Based Stains:
Film-forming (creates a protective layer on the surface)
Durable and long-lasting when applied correctly
Easy cleanup and unlimited color options
Good for vertical surfaces like fences
Cons: Fails quickly on walked-on surfaces, chips and peels, can lock moisture into wood
Oil-Based Stains:
Penetrating (soaks into the wood rather than sitting on top)
Preserves and conditions wood from the inside
No chipping or peeling (non-film-forming types)
Highlights natural wood grain
Easy maintenance and touch-ups
Cons: May fade sooner and require more frequent reapplication, harder cleanup, solvent smell
Film-forming stains (whether water-based or oil-based with wax) create a protective layer on the wood surface. While durable, they have several drawbacks: they peel and crack over time, especially if not applied correctly; they require extensive maintenance including sanding or stripping before reapplication; they can create slippery surfaces when wet; and they can trap moisture in the wood, potentially leading to rot. These stains also perform very poorly on horizontal surfaces with foot traffic.
Non-film-forming oil-based stains penetrate deep into the wood rather than sitting on top. This allows the wood to breathe while protecting it from moisture and UV damage. Because they don’t create a surface film, they never peel or chip — they simply fade over time. This makes maintenance much easier: you just clean and reapply without extensive stripping or sanding. The oil conditions the wood like sap in a tree, helping prevent warping and cracking while keeping the wood looking natural.
Transparent:
Minimal pigment, shows full wood grain
Basic UV protection
Best for new wood or wood in excellent condition
Semi-Transparent:
Moderate pigment, adds color while showing most grain
Better UV protection than transparent
Great all-around choice for most decks and fences
Semi-Solid:
Higher pigment, more opaque but still shows some texture
Strongest UV protection
Best for older/weathered wood or areas with intense sun exposure
Staining Process & Application
Proper preparation is essential for long-lasting results. The process depends on your deck’s condition:
New Deck:
Deck washing and spot sanding any rough areas
New decks are ready when moisture is 13% or less
Some pine decks need washing to remove mill glaze
Weathered/Gray Wood:
Deep cleaning with wood-safe cleaner
Brightening treatment
Sanding for smoothness
Previously Stained (Film-Forming/Peeling):
Power washing
Chemical stripping if needed
Full sanding to remove old finish
Basic Cleaning Steps:
Remove all debris, leaves, and dirt
Apply deck cleaner to break down dirt, mold, and mildew
Scrub with stiff-bristle brush or use low-pressure power washer
Rinse thoroughly
Let dry completely (wood moisture below 15%)
For non-film-forming oil-based stains, you only need ONE FLOOD COAT. Wood can only absorb a certain amount of stain before becoming oversaturated. Apply generously until the wood won’t absorb more, then wipe off excess after 15-30 minutes to prevent tackiness. If the wood is extremely dry, you may apply a second “wet-on-wet” coat within 30 minutes to an hour while the first coat is still wet. Never apply multiple coats that create buildup on the surface, as this causes stickiness and doesn’t improve protection.
Drying time varies by stain type:
Oil-based penetrating stains: 24-48 hours before walking on the deck
Water-based stains: Generally faster drying
Always check weather forecasts and ensure at least 24 hours of dry weather for proper curing
Use the water drop test: Sprinkle water on the deck. If it soaks in within a few seconds, the wood is ready. If it beads up, wait longer for the wood to dry or for pressure-treated chemicals to evaporate. You can also use a moisture meter — wood moisture should be below 15% for proper staining.
New decks are ready for stain when moisture is 13% or less. This typically takes 3-6 months for pressure-treated wood to fully dry from the treatment chemicals. You can test if your deck is ready using the water drop test. Some pine decks need washing to remove mill glaze before staining. If UV rays are hitting the deck daily, it may be ready sooner. Don’t rush it — staining too early can trap moisture and cause problems.
Maintenance & Troubleshooting
Regular maintenance extends the life of your deck:
Annual wash with diluted bleach solution to control organic growth (moss, mildew, mold)
Reapply stain every 2-3 years to keep oil in the wood
Keep lots of oil in the wood to avoid warping and cracked boards
With oil-based penetrating stains, maintenance is simple: just clean and reapply — no stripping or heavy sanding needed
Common causes include:
Using film-forming stains on horizontal walked-on surfaces
Improper surface preparation before staining
Applying too many coats or over-application
Staining wood that wasn’t fully dry
Using low-quality stains from big box stores
Solution: Switch to non-film-forming penetrating oil stains which never peel — they just fade over time
For oil-based stains, use a stripping agent designed to break down oil-based products. Apply the stripper, let it work for the recommended time, scrub or power wash (using appropriate pressure to avoid wood damage), then clean and brighten the wood before applying new stain. Film-forming solid stains may require more aggressive stripping methods and full sanding to remove completely.
Choosing Stain Colors
Consider these factors:
Natural look: Choose transparent or light semi-transparent tones
Enhanced color with grain visible: Semi-transparent in cedar, redwood, or walnut tones
More color coverage: Semi-solid for a richer, more uniform appearance
Wood condition: Newer wood shows grain better; older weathered wood benefits from higher pigment
Sun exposure: Higher pigment (semi-solid) provides better UV protection for sunny areas
Pet Safety
Look for stains that are pet-safe once fully cured. Oil-based stains do have solvent odors during application and drying, so keep pets off the deck for the full 24-48 hour curing period. Once cured, quality penetrating oil stains are safe for pets. Water-based options may cure faster but check specific product labels for pet safety information.
Hiring a Deck Staining Contractor
What type of stain do you use? (Oil-based penetrating vs. water-based film-forming)
How do you prepare the surface? (Look for thorough cleaning, stripping if needed, and proper drying time)
Do you offer warranties on your work?
How many coats will you apply and why?
What is your maintenance recommendation?
Do you buy stain from big box stores or professional suppliers?
Can I see examples of your previous work?
Yes! Fences and decks up to 20 years old can look new again. The process of cleaning, stripping, and sanding is crucial to restoration. Once properly prepared, applying a quality penetrating oil stain will help preserve the deck against the elements it faces. However, if wood boards are soft, rotted, or severely damaged, replacement may be necessary.
Buying Deck Stain
It’s not recommended. Products like Behr and Thompson’s Water Seal from big box stores often don’t perform as well as professional-grade stains from local paint stores. No matter how good the marketing looks, these consumer products typically fail faster and may not provide adequate protection. Call a local paint store or specialty supplier for professional-grade products.
Look for:
Penetrating formula (not film-forming)
Oil-based for best wood conditioning
Quality pigments for UV protection
Low solvent content (avoid stains filled with paint thinners)
Professional-grade formulation from specialty suppliers
