TWP with Wet on Wet Application Tips
TWP Stains are to be applied “Wet on Wet” when the wood is absorbent enough to handle more than 1 coat of the stain. This is typically for wood and decking that is older than 12 months and has been exposed to the elements. Applying the TWP “wet on wet” is similar to applying 1.5 coats of stain. The second coat covers twice as much square footage as the first coat.
Key TWP Stain Tips
- Apply TWP wet on wet only when wood is older than 12 months and absorbent enough for more than one coat.
- Start with verticals like railings and benches, then apply to horizontal flooring, finishing with stairs last.
- Apply your second coat within 10 to 60 minutes of the first coat, watching for puddling under railings and benches.
- Do not apply 2 coats to new or recently sanded wood finer than 60 to 80 grit, as TWP may not fully absorb.
Applying TWP “wet on wet” is very easy and not complicated once you understand the simple steps.
How To Apply TWP Wood Stains “Wet On Wet” to a Deck:
- Apply the TWP to the verticals first. This would include the railings, benches, and any vertical walls.
- Lightly apply one coat of stain to the horizontal flooring. Apply to the entire floor surface. If your deck has multiple levels, do one level at a time before moving to the next level.
- Wearing shoes that are disposable, walk back onto the “wet” stain and reapply another coat to the “tops” of and railings, walls, and benches. You may walk on your first coat of stain 10 minutes after finishing.
- Apply your second coat of stain to the horizontal flooring. Take care to not step in or leave footprints in your second coat!
- Finish stairs last, repeating the above steps.
TWP Staining Tips
- Do not apply 2 coats of stain to new wood or decking or to recently sanded wood that was sanded finer than 60-80 grit as the TWP stain may not be able to fully absorb into the wood.
- In most cases, a second coat only needs to be applied to horizontals as the verticals will last twice as long.
- Apply your second coat of stain within 10-60 minutes of the first coat.
- Watching for puddling on the floor. This usually happens under railings and benches.
- Wear shoes and clothes that are disposable. Do not wear shoes that have black soft rubber soles. The TWP can “soften” these soles, leaving black residue marks on your deck if you step in the stain.
- TWP Wood Stains can be applied with a stain pad, brush, roller, or sprayer.

How long should I wait to apply semi solid stain after using RAD Stripper and power washing my deck to clean it?
Wait a minimum of 48 hours after the prep and power washing before applying the semi-solid. Make sure you neutralized the RAD Stripper with the Restore-A-Deck Brightener while the wood was still wet — the stripper leaves the wood too caustic for the stain to penetrate properly if it is not brightened. Once the prep is done, stain within 2 weeks. Apply between 50-90 degrees and do not stain if rain is expected within 12 hours.
if it rains 30 hours after applying twp 1500 will it cause any issues
No, that should not cause any issues. The standard minimum is 12 hours of dry weather after applying the TWP 1500, and rain 24+ hours out is generally fine. At 30 hours you are well past that. The one issue would be if you severely overapplied the stain.
