Topcem Pronto Slurry is a specially formulated bonding slurry designed for use before installing Mapei Topcem Pronto bonded engineered screeds. It promotes excellent adhesion between the screed and the prepared substrate, ensuring strong, long-lasting performance.
This two-component system combines Topcem Pronto Slurry powder with Planicrete or Planicrete SP latex additive, providing a smooth, consistent slurry that’s easy to apply using a trowel or brush. The slurry must be applied wet-on-wet with the Topcem Pronto screed for optimal bond strength.
Suitable for both indoor and outdoor installations, Topcem Pronto Slurry is ideal for commercial and residential flooring projects requiring durable, high-performance bonded screeds.
