  • Do I need to use a primer with Foundation Sealant?

    Depending on your application. A primer would not typically be used on exterior foundations, however would be recommended on interior projects

  • Can I coat over an existing coating or paint?

    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.

  • Can Color Sealant be used over a bitumen coating?

    No. These are not compatible chemistries and will not provide and adequate bond. The bitumen will also eventually bleed through the colored coating.

  • How long does it take to get my order once I have placed it?

    US - Delivered in 3-5 business days
    CAN - Delivered in 3-7 business days
    UK - Delivered in 2-3 business days
