Mapei Adesilex P4 Grey Thick Bed Flexible Floor Adhesive 20kg

Lay large format tiles with absolute confidence using Mapei Adesilex P4. This high-performance, standard-setting adhesive is specifically engineered to make fixing large, heavy floor tiles and outdoor porcelain slabs easier, faster, and more reliable.
Adesilex P4's genius lies in its pourable, "full-contact" formula. It flows easily to fill any voids, guaranteeing 100% coverage on the back of the tile without the need for strenuous "back-buttering." This is essential for ensuring a solid, permanent bond for large format porcelain and natural stone, eliminating the risk of hollow spots and future cracks.
This is a true problem-solver for uneven floors. As a thick-bed adhesive, it can be applied up to 20mm thick, allowing you to smooth out imperfections in the substrate as you tile, saving you the time and expense of applying a separate levelling compound. Its S1 flexibility makes it perfect for outdoor patios where thermal movement occurs, and for use over underfloor heating systems
