Can I apply this straight to plywood to waterproof? I am building a dog house and want to waterproof the roof on it, but dont want to buy 100ft roll of asphalt covering. Would this work well instead?

Asked by: DsprteMeasres
This will act as a paint for wood surfaces, and will form a protective coating. If you project requires a permit, make sure you follow local building codes.

Can this be painted and will it adhere to painted concrete foundation?

Asked by: JC80
Yes, this will adhere to a sound surface, and it can be painted. However some bleed through staining may occur if you do not use a stain blocking primer. If this is a visible wall and you want color accuracy, use a stain-blocking primer before painting. Due to the limited information we have on your project, please read the Technical Data Sheet (TDS) for further product information, and proper prep and application instructions. You'll find the TDS and helpful how-to videos on the individual product page of All the best with your project.
