Massetto Pronto BM 81 is a ready to use mortar made of Natural Hydraulic Lime NHL 5 of our production (certified according to EN 459-1), pozzolana activators and selected aggregates for internal and external screeds at medium fast drying. Massetto Pronto BM 81 is specific for screeds similar to the traditional ones but that allow the laying of tiles after 20 days, of natural stone, terracotta and parquets after 30 days, since after this period of time the residual moisture of the screed is normally lower to 2%. It is recommended to check the degree of humidity before the laying of tiles especially in the winter period when the low temperatures reduce the drying of the lime. To achieve this value it is necessary that no moisture rises from the underground.
