Questions about Exterior Foundation Sealing

  • No. Primer is not needed for this application.

  • It is recommended to remove oil based or recently applied coatings.
    You can apply over most acrylic/latex, polyurethane, alkyd paint, epoxy paints/coatings with the use of our Liquid Rubber Multi-Purpose Primer and using proper cleaning/preparation techniques. Keep in mind that when you apply over an existing coating or paint, if that coating/paint peels, our coating will peel with it as it is bonded to the existing coating/paint and not directly to the substrate.
