Valspar One-Coat Transparent Exterior Stain & Sealer - Transparent - 1 Qt, Red Naturaltone

Thank you for taking the time to review the Valspar Stain. Since the Valspar Stain products are penetrants, and should not peel or flake off. If the product is peeling, the surface was not porous enough to accept the stain. We generally recommend doing a "splash test" prior to application to ensure the surface will accept our product. At this point you can either sand the surface or use a power washer in conjunction with a chemical stripper to remove all peeling or flaking areas. Before you apply any more product, I would first test your surface by performing a "splash test." This is done by splashing some water on the surface. The water will do one of two things: *Absorb into the surface making it slightly darker. This is a sign that another coat of product will effectively absorb into the surface and you can apply our product successfully. *Water will puddle or just run off. This means that the surface is already sealed and our products will just form an oily, tacky layer on top. We would not recommend applying our products at this time. As long as the water test shows that the surface is absorbent, then you can proceed to perform a test area. This is important for two reasons -- it will help you learn how much product to apply before the surface is saturated and also show you what degree of discoloration will occur. As you will notice, once the surface has absorbed a certain amount of our product, then the remaining waterproofer just sits on the surface and can lead to oiliness, blotchiness, or discoloration. For this reason we recommend test areas to determine the porosity of the substrate and how much product you can apply in any given area.
