Mapei Topcem Pronto Slurry

Mapei Topcem Pronto Slurry

Mapei Topcem Pronto Slurry is a special cementitious bonding slurry designed specifically for use before the installation of Topcem Pronto bonded engineered screeds. It creates a strong bond between the prepared substrate and the new screed system.

Suitable for both internal and external applications, the slurry is applied immediately before the Topcem Pronto screed using a wet-on-wet application method to achieve optimum adhesion. 

Key Features:

• Purpose-made bonding slurry for Topcem Pronto screeds
• Promotes strong adhesion between substrate and screed
• Suitable for internal and external applications
• Designed for bonded engineered screed systems
• Applied in a continuous 2–3mm layer
• Can be applied using a flat brush, scrubbing brush or trowel
• Used with Planicrete SP or the specified Planicrete and water mixture
• Wet-on-wet application for optimum adhesion
• Suitable for residential and commercial screeding applications 

Typical Applications:
Ideal as the bonding layer between a properly prepared cementitious substrate and a Topcem Pronto bonded screed, including flooring, wet-area and other suitable screed installations.

Mixing Ratio:
Mix 3 parts Topcem Pronto Slurry with 2 parts Planicrete SP, or as an alternative, 3 parts slurry with 1 part Planicrete + 1 part water. 

Consumption:
Approximately 2–2.5kg/m², depending on application thickness.

Packaging:
20kg bag.
