The use of Deck Cleaners and Deck Stains Strippers when prepping wood for a coat of deck stain will cause the pH balance to increase. This is due to the mild caustics (bases) that the cleaners and strippers use, making the products more effective in the cleaning process. The side effect is that the pH is changed and will “darken” the natural wood color. The Deck Brightener (mild acids) will neutralize the caustic of the cleaner or stripper setting the pH balance to a neutral 6. Using a deck brightener will increase the longevity of the stain as well.
Wood Deck Brightening is a much needed and easiest step in the entire prepping process.
The following steps should be used when applying a deck brightener:
- Use a Deck Cleaner or a Stain Stripper prior to using a Deck Brightener.
- Make sure all dirt, grime, an old stain residue is rinsed from the deck after the cleaning/stripping.
- Apply the Deck Brightener as soon as the cleaning is done. Best to apply while wood is still wet.
- Let the brightener sit for 10-15 minutes.
- Rinse wood thoroughly when done. Heavy washing or scrubbing is not needed.
