Signs that your deck needs to be treated again with TWP.
Typically, your deck should be treated with a maintenance coat about every three years for surfaces that you walk on and every 5 to seven years for other surfaces such as rails and spindles. Here are some signs that show it is time to re treat your deck:
- The color that you applied may become lighter.
- Mold (Black) or Algae (Green) may appear on the surface.
- Water no longer beads on the surface.
- Stain color wears off where there is a lot of foot traffic.
Preparing your deck for a maintenance coat of TWP Stain.
A light cleaning of the surface is all you need to do to re-apply TWP Stain. There is no need to strip the old stain off or for any sanding. To clean the deck, you can create a cleaning solution using the formula below or purchase our Deck Wash Pro product.
When cleaning we recommend using a 5 Gallon Bucket, Scrub Brush and a garden house. If want you can use a pressure washer but you will want to keep the pressure down and the tip at least a foot away from the surface. You are not trying to remove stain – just the dirt and mold that has built up over the past few years.
Cleaning Solution Mixture
5 Gallon Bucket – 75% Water and 25% Bleach with a half teaspoon of dishwashing detergent (liquid). Wet your deck then using your scrub brush work the cleaning solution over the boards and rinse thoroughly with your garden hose or pressure washer.
