Ready to use prepacked mortar for fast-drying (4 days) normal setting screeds with controlled shrinkage.
Applications: Formation of floating and bonded screeds on existing and new slabs for the installation of ceramic tiles, stone material, or any other flooring where fast drying is required for short installation times. Topcem Pronto is ready to use and must be mixed just with water. Topcem Pronto is the ideal solution where good quality graded aggregate is hard to find or for job sites such as those in city centres where the logistics involved in mixing conventional binders can be difficult. Topcem Pronto is suitable for screeds used in interiors and exteriors. Bonded screeds and patching (less than 35 mm thicknesses) first require the application of a Topcem Pronto and Planicrete anchoring slurry. ì For floating screeds (thicknesses above 35 mm) lay a polyethylene sheet beforehand.
Technical data: Recommended mixture ratio: one 25 kg bag of Topcem Pronto with 1.7 l of water. Open time of the mixture: 40-60 minutes. Set to light foot traffic: after 12 hours. Waiting time before installation: 24 hours for ceramic tiles and 2 days for natural stone. Residual moisture after 4 days: less than 2%. EMICODE: EC1 R - extremely low emission level. Storage: 12 months.
Consumption 18-20 kg/m2 per cm of thickness in relation to the degree of compaction.
