Mapei Ready-Mixed Fast-Drying Screed Mortar, 25Kg, Suitable for Internal and External Floors and Heated Screeds

It comes as a 25 kg bag of ready-to-use cement screed that can be mixed with water to obtain a flowable, self-leveling consistency. It is designed for rapid setting, allowing traffic and flooring to be ready within about 60 minutes. It supports thicknesses up to 100 mm when used as a combined substrate and screed, and it can be used over underfloor heating systems. It is suitable for internal floors and walls and provides a smooth finish suitable for direct tile adhesion.

1) Clean and prepare the substrate, removing dust and loose material. 2) Mix TOPCEM Pronto with clean water to achieve a flowable, self-leveling consistency as recommended by MAPEI. 3) Pour onto the substrate and allow it to self-level; finish by trowelling, raking, or floating to obtain a smooth surface. 4) Allow the screed to cure and then proceed with the chosen floor coverings after the stated setting time.

TOPCEM Pronto is suitable for internal subfloors and walls and can be used as a base for various floor coverings. It is designed to be a smooth, level substrate and is suitable for direct adhesion of ceramic tiles. It can be used over existing substrates and underfloor heating systems (in combination with the substrate and screed up to 100 mm thick).

TOPCEM Pronto is a pre-mixed cementitious screed intended to be mixed with clean water according to MAPEI's guidelines. It does not require additional proprietary additives beyond the water specified for achieving the correct consistency.

Yes. TOPCEM Pronto can be used over underfloor heating systems when applied as a combined substrate and screed, with thickness up to 100 mm, following the system guidelines provided by MAPEI.

TOPCEM Pronto can be trowelled, raked, or floated to achieve a smooth finish suitable for direct tile adhesion and other floor coverings after the specified setting time.

Always follow PPE recommendations (gloves, eye protection, and appropriate clothing). Work in a well-ventilated area, and avoid prolonged skin contact with fresh material. Store in a dry place in its original packaging and keep away from moisture. Read the product label and safety data sheet before use for detailed guidelines.

TOPCEM Pronto is formulated to be ready for traffic and flooring within about 60 minutes after placement, depending on ambient conditions such as temperature and humidity. Always follow the manufacturer’s curing guidance for your specific environment.

It is ideal as a quick-setting base for many floors, including residential and commercial spaces (homes, offices, garages, warehouses).

Avoid applying on very damp or contaminated substrates, do not exceed recommended thickness, ensure proper mixing to achieve a consistent flow, monitor cure conditions to prevent premature drying or excess moisture loss, and avoid loading the screed before it has fully cured.

TOPCEM Pronto provides a quick-setting, ready-to-use solution that can reduce labour time and downtime. When evaluating value, consider total project time, required thickness, compatibility with your floor coverings, and whether rapid turnover meets your project schedule. A 25 kg bag is compact for easy handling, and using the product as a fast base layer can save time compared with slower traditional screeds.
