Staining pressure treated wood has limitations. Some products work better than others.
Wait First
New PT lumber is wet. Stain won’t penetrate or adhere. Wait 3-6 months typically. Water bead test to confirm.
Semi-Transparent Wins
Best choice for PT wood. Shows grain, adds color, doesn’t trap moisture underneath.
Ready Seal is popular. No primer needed. Forgiving application. Multiple colors.
Cabot Australian Timber Oil. Premium option. Expensive but lasts. Penetrates deeply.
Solid Stain Alternative
More like thin paint. Hides grain but provides more color. Peels eventually unlike semi-transparent.
Behr Solid works okay. Not my favorite but accessible. Sherwin-Williams SuperDeck is better.
What To Avoid
Oil-based on newer PT. The treatment resists oil penetration. Water-based adheres better now.
Thick film finishes. Spar urethane, deck paint. Traps moisture, peels, looks terrible in a year.
Application
Clean first always. Brightener helps too. Restores wood tone before staining.
Apply with brush, roller, or pump sprayer. Back-brush to work it in. Avoid puddles.
Maintenance
Reapply every 2-3 years. Annual in harsh climates. Light cleaning, light sanding, fresh coat.
Consistent maintenance is easier than restoration. Don’t let it go too long.
