Painting — FAQ
Can I use a pressure washer with gel paint strippers?
Yes, but apply the gel first, let it dwell, then use a pressure washer at 1,500-2,000 PSI with a 25-degree tip to remove residue. Don't inject gel through the washer — it clogs downstream injectors. Use liquid stripper like DeckGeneral for injection systems.
How long should I wait before re-staining my deck after stripping?
Wait 48-72 hours after final rinse for the wood to dry to 15% moisture content. Test with a moisture meter. If you used an alkaline stripper, neutralize with oxalic acid solution first, then rinse and let dry. Rushing leads to stain failure.
Will paint stripper damage my deck wood?
Quality wood-specific strippers won't damage sound wood. Avoid over-application and excessive dwell times beyond manufacturer specs. Alkaline strippers can darken some woods — neutralize promptly. Always test on an inconspicuous board first.
What's the best way to strip paint from deck railings and spindles?
Use a no-drip gel formula like MAX Strip Professional Strength. Apply with a 2-inch angled brush, working in 3-foot sections. Wrap spindles in plastic wrap after application to prevent drying. Let dwell 45 minutes, then scrape with a pull scraper following the wood grain.
Can I strip paint from my deck in cold weather?
Most strippers become ineffective below 50°F. Chemical reactions slow dramatically. Wait for temperatures above 60°F for best results. If you must work in cool weather, extend dwell time by 50% and tent the area with plastic to trap warmth.
How do I dispose of stripped paint and stripper residue?
Collect scraped material in heavy-duty contractor bags. Check local regulations — many areas classify paint waste as hazardous. Never rinse residue into storm drains or landscaping. Dry out liquid residue with kitty litter before bagging for landfill disposal.
