Product Options:


TOPCEM PRONTO is a ready-mixed mortar, easy to use with high thermal conductivity, for high-efficiency heated floors. Dries more quickly than normal sand/cement screeds to make your work simpler and quicker.

Where to use:

For forming unbonded and bonded screeds on new and existing slabs in interiors and exteriors prior to installing wood, PVC, linoleum, ceramic tile, natural stone, carpet or other floor coverings in areas where fast-drying screeds are required in order to lay floorings in a short time

Preparation of the substrate
Topcem Pronto can be used on any substrate as long as it is not subject to rising damp. If so, use a waterproof membrane.

For screeds from 10 to 35 mm thick, that require anchoring, the substrate must be dry, without cracks, free of dust and loose particles, varnish, wax, oil, and gypsum residues.

Preparing the mix
Topcem Pronto can be mixed in:

  • Rotating mixers;
  • Normal job site mixers;
  • Centrifugal mixers;
  • Automatic pressure pumps.

Mix one 25 kg bag of Topcem Pronto with 1.7 l of water for at least five minutes. Never vary the amount of water because this will weaken the mortar’s final performance.

The mix should have a semi-dry consistency. Tamp and float the mix until a dense, smooth surface is obtained without bleeding.

Workability time: 40-60 minutes.
