Water Based Curing Compound & Clear Sealer (BBA)


Cure-Seal WB is a non-degrading acrylic resin sealer which forms a clear, elastic, durable matrix on the surface of cementitious substrates.

When used as a curing membrane on Flexcrete mortars and coatings, it conforms to the requirements for water retention given in ASTM C309. It can also be used as a sealer coat for concrete.

Cure-Seal WB is also used as a clear lacquer which can be applied to damp but surface-dry substrates to form a tough, glossy finish. When used in combination with Cemprotec E-Floor, it seals in and retains aggregate to provide enhanced slip and abrasion resistance.


  • Convenient alternative to traditional curing aids such as polythene sheeting, damp hessian or sand.
  • Spray applied when used as a curing membrane.
  • Can be roller applied on floors after overnight cure.
  • Allows controlled release of substrate moisture.
  • Odourless water-based product, ideal for internal use.
  • Does not degrade on external exposure.
  • Non-yellowing, light gloss appearance.
  • Does not blush when wet.
  • Enhances adhesion of subsequent coatings.
  • Retains aggregate broadcast for slip resistant flooring.


Approved by the BBA, Certificate No. 05/4276. ASTM C309.
