Soil preparation and leveling Before installing underfloor heating beneath tiles, the surface must be carefully prepared. A clean and even floor ensures better thermal efficiency and prevents energy loss. 1. Surface cleaning The floor must be clean, dry, and free of dust or residue. It is advisable to repair any cracks or unevenness before applying a leveling compound. 2. Application of the leveling product A suitable leveling compound will create a smooth, flat surface, essential for installing heated mats. Spread it evenly and allow it to dry completely before proceeding. 3. Choosing tile adhesive It is crucial to use an adhesive compatible with underfloor heating. Adhesives specifically designed for underfloor heating offer excellent adhesion and remain flexible, allowing them to withstand thermal expansion without cracking. Types of tile adhesives Standard adhesive : suitable for conventional interior applications. Flexible adhesive : ideal for high-traffic areas and underfloor heating systems. Fast-drying adhesive : perfect for projects requiring quick application. Installation of underfloor heating beneath tiles Installing electric underfloor heating beneath tiles requires precision and care.
