Mapei Topcem Pronto is a factory-blended, ready-to-use rapid-drying screed mortar. Pre-mixed with selected aggregates and Topcem binder, it delivers consistent quality without on-site batching. It is ready to receive ceramic tiles in approximately 24 hours, natural stone after 2 days and parquet and resilient flooring after 4 days, making it ideal for fast-track projects where traditional screeds would cause programme delays.

Key Benefits

Application

Empty the bag contents into a forced-action mixer and add 1.7 litres of water per 25 kg bag. Mix for 5–10 minutes until a uniform, semi-dry earth consistency is achieved. Lay onto the prepared substrate and compact firmly using a tamper or roller. Level with a straightedge and finish with a float or power trowel. Apply at temperatures between +5°C and +35°C. Minimum depth 35 mm unbonded, 10 mm bonded.

Coverage

Approximately 20 kg/m² per 10 mm thickness. One 25 kg bag covers approximately 1.25 m² at 10 mm or 0.25 m² at 50 mm depth.
