Application Tips:
-
Clean the surface thoroughly (remove dirt, mold, and mildew). Check out our Wood Cleaner and Brighteners.
-
Perform a water test to check for absorbency
-
Stir the stain well before and during use
-
Apply a generous, even coat without allowing the stain to puddle. For optimal penetration and appearance, back-brush while the stain is still wet to ensure even distribution and a smooth, uniform finish.
-
Semi-transparent oil stain should be absorbed by the wood, not left sitting on the surface.
-
Use our brush made for oil-based stain, sprayer, or roller
One coat is often enough, especially on vertical surfaces. For decks and other horizontal areas, always wipe away any excess stain after application to reduce drying time and prevent tracking or transfer. For optimal absorption, apply to wood that feels slightly rough; sanding to 40 grit is ideal, with 80 grit being the maximum. Ultra-smooth surfaces won’t absorb penetrating oil as effectively, limiting performance and longevity.
Coverage:
-
Approximately 150–175 sq. ft. per gallon, depending on surface and porosity
-
One 5-gallon pail covers up to 875 sq. ft. on rough wood

Pro Advice
FAQs: Semi-Transparent Stain
Your questions answered, Learn how to get the best performance from EXPERT Stain & Seal, the pro-grade, oil-based solution trusted across North America for fence, deck, and exterior wood protection.
How many coats should I apply?
For most fence and deck projects, one coat is often enough, especially on rough-cut or highly absorbent wood. For smoother or denser surfaces, a second coat may be applied wet-on-wet for added richness and coverage.
Tip: Always avoid over-application. Only apply as much stain as the wood can absorb without puddling.
Can I apply this stain over a previously stained surface?
Yes, EXPERT Stain & Seal can be used over previously stained wood. Just make sure the surface is clean and dry. If the previous stain was a film-forming or acrylic type, sanding or stripping is recommended to ensure proper penetration and bonding.
How do I maintain my deck after staining?
Regular maintenance will extend the life of your finish. Clean your deck or fence 1–2 times a year with a gentle wood cleaner like our EXPERT Wood Care Eco Cleaner. For deeper cleaning, use a low-pressure power washer.
Also consider a light recoat every 2–3 years, depending on UV and weather exposure.
What surfaces can a semi-transparent stain be used on?
This stain works on virtually all exterior wood, including fences, decks, stairs, pergolas, gazebos, log homes, wood siding, railings, privacy screens, rough-sawn wood, smooth lumber, pressure-treated lumber, and even exotic hardwoods with proper preparation.
How long does the semi-transparent stain last?
Expect 3 to 5 years of protection on vertical surfaces and 2 to 3 years on high-traffic, horizontal surfaces like decks, depending on climate and exposure.
Routine cleaning and timely recoating can double the life of your stain job.
Can I use this stain on both vertical & horizontal surfaces?
Absolutely. EXPERT Stain & Seal is formulated to protect and beautify both vertical and horizontal wood surfaces. Just remember: horizontal areas like decks experience more wear and may require earlier maintenance.
