TWPStainHelp.com Tips: TWP Stain Application is Spotty/Shiny and How to Fix
Staining a deck can be a challenge. There are some common mistakes that can occur that may greatly affect the final results. One such common mistake is over applying the stain.
With TWP Stain it is recommended to apply the stain using a brush, roller, or some type of sprayer. If the wood seems very thirsty, you can apply two “wet on wet” coats. TWP is a penetrating stain so you should never apply more stain than the wood can absorb. Once the stain as had 20-40 minutes or so to penetrate into the wood, you should go back and wipe away or back brush any puddles, drips, or runs.
