Polyseal WB

Pure Acrylic Non-Yellowing Concrete Cure and Seal

Polyseal WB is a high solids, water-based, non yellowing, acrylic concrete curing and sealing compound. This state-of-the-art proprietary formulation forms a tough acrylic film to effectively cure fresh concrete and protect older concrete.

Polyseal WB creates a medium gloss membrane which remains clear throughout its service life. Polyseal WB can be colored with Polyseal WB Tint in a variety of standard and special colors.


  • Interior concrete where a curing compound that meets ASTM C1315 standards is desired, but where the fumes from a solvent based product would be objectionable.
  • Exterior concrete curing where a non-yellowing formulation is preferred and water-based clean-up is desired.
  • Enhance the color and provide a uniform appearance of dry shake hardened floors, integral colored concrete and acid stained concrete while curing and sealing the surface.
  • Seal and dustproof older interior or exterior concrete.


  • Protects concrete surfaces against deicing chemicals, fertilizers, salts, grease, oil, alkalies, mild acids and detergents.
  • Minimizes spalling due to freeze-thaw cycle exposure, hair line checking, premature cracking, dusting and other common defects which result from improperly cured concrete.
  • Seals out most construction dirt and stains, and prevents mortar, plaster and concrete droppings from bonding to concrete surfaces.
  • Tint pack system available in twelve standard colors; special color matching available subject to minimum quantities.
  • Tinted Polyseal WB may be used to cure or seal rough finished colored concrete and aids in hiding finishing imperfections or variations in color.

      Ask a Question
      • What steps are necessary to apply this WB product over a stamped concrete surface that may have been sealed previously with a solvent-based sealer?

        You will need to pressure wash or strip the old sealer off.

      • Can this product be used on a Travertine pool deck?


      • Is there an expiration date for this product if 1. Unopened 2. Opened ?

        Unopened is typically a year,  opened is less and depends on how much is in the pail and how it is stored

      • What is the difference between ChemMasters Polyseal and Polyseal WB? I just had concrete poured, and they used Polyseal (no WB) for the first coat. Should I be using the same product (no WB) for the second coat, and is that something you sell? Thanks, Mark

        Polyseal WB is water based.  You should use the same product as the first coat so not water based. We do sell both.

      • Can I use this on stamped concrete that was sealed with an oil based sealer for years ago

        I would suggest using a solvent based sealer over your existing solvent based sealer instead of water based, as there is less prep required

      • Can i use this on Pavers as well?


      • I recently applied this to my drive with a roller ... after the first rain I noticed the water did not bead. It did bead in spots on the smooth edges ... did I put it in too thin?

        Depending on the condition of the concrete, it could have soaked all of the sealer up and could use another coat.

      • What are the different colors you have for the sealer, and what is the cost and coverage of 5 gallons. Thanks

        Here are the copies: Tint Colors
        Coverage is about 350 sqft per gallon. Give us a call for pricing

      • Will this product help deter mold forming on a concrete drive in a south Florida climate?

        Yes.  It forms a barrier between the concrete and the moisture.
