Can I pour self-leveling underlayment over LATICRETE Floor HEAT?
Make sure that the floor meets deflection and construction standards (consult Technical Data Sheet #152 at www.laticrete.com) and tape all board joints. Apply LATICRETE Blue 92 Anti-Fracture Membrane to the plywood surface. Install the tile or stone using LATICRETE 333 Super Flexible Additive mixed with LATICRETE 317. Grout using LATICRETE 1500 Sanded Grout gauged with LATICRETE 1776 Grout Admix.
