Removing solid stain from a deck typically involves a combination of chemical stripping and sanding. While chemical strippers handle the bulk of the removal, sanding tackles stubborn spots.
Here's a breakdown of the process:
1. Chemical Stripping:
- Application: Apply a chemical paint stripper designed for decks according to the manufacturer's instructions. These strippers work by softening the stain, making it easier to remove.
- Waiting Time: Allow the stripper to sit for the recommended time, typically 15-30 minutes. The stain should start to bubble or lift.
- Scraping: Use a plastic scraper to remove the loosened stain. Avoid metal scrapers, as they can damage the wood.
- Rinsing: Thoroughly rinse the deck with water to remove all traces of the stripper. Consider using a pressure washer on a low setting, but be cautious to avoid damaging the wood grain.
2. Sanding (For Stubborn Spots):
- Drying: Allow the deck to dry completely after rinsing.
- Choosing a Sanding Tool:
- Angle Grinder with Paint Stripping Disk: This is the fastest option for removing stubborn stain. Use caution and move slowly to avoid gouging the wood.
- Power Drill with Paint Stripping Disk: A slower but more controlled option than an angle grinder.
- Orbital Sander: Use with coarse-grit sandpaper (e.g., 60-80 grit) for smaller areas or detail work.
- Sanding Technique: Sand in the direction of the wood grain to avoid cross-grain scratches. Apply even pressure and avoid dwelling in one spot for too long.
- Dust Removal: Thoroughly remove all sanding dust with a brush, vacuum, or damp cloth.
3. Preparation for Restaining (After Stripping and Sanding):
- Cleaning: Clean the deck with a deck cleaner and brightener to neutralize the wood and open its pores for better stain adhesion.
- Drying: Allow the deck to dry completely before applying a new stain.
- Testing: Before staining the entire deck, test the new stain in an inconspicuous area to ensure you like the color and that it adheres properly.
Important Considerations:
- Safety: Wear appropriate safety gear, including eye protection, gloves, and a respirator, when working with chemical strippers and power tools.
- Wood Type: The best method for removing stain may vary depending on the type of wood your deck is made of. Consider a test area before a full application.
- Environmental Concerns: Dispose of used chemical strippers and sanding dust properly according to local regulations.
In summary, effectively removing solid stain from a deck requires a combination of chemical stripping and sanding, with proper preparation and safety measures being crucial for a successful outcome.
