Servoflex-Trio-SuperTec will hold heavy stone, large tiles without sagging. Heated floors can be operational after three days only. Servoflex-Trio-SuperTec is especially suitable for large modular ceramic tile installations, porcelain stoneware and natural stone coverings on limited form stable substrates such as heated screed (please follow the respective regulations and data sheets), in situ concrete (at least 3 months old) and similar. By increasing the water content to approx. 1.8 US gal. (7.0 liters) per bag you yield a pourable floating bed mortar allowing an even installation without air pockets. Thus the back buttering-floating technique does not apply here.
