Topcem Pronto is a ready-to-use, normal setting, quick-drying mortar with high thermal conductivity. Topcem pronto forms 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.
