Adhesive & Levellers FAQ’s

Flexible tile adhesive is designed to accommodate the natural expansion and contraction that occurs as your underfloor heating system warms up and cools down. Unlike standard adhesives, flexible adhesives help prevent tiles from cracking or becoming loose over time, making them the recommended choice for both electric and water underfloor heating installations.

Self-levelling compound creates a smooth, level surface before your final floor finish is installed. It is commonly used to encapsulate electric underfloor heating mats or cables, protecting the heating elements while providing an even base for tiles, vinyl, laminate or other flooring. It also helps improve heat distribution across the floor.

In most cases, electric heating mats or cables should first be covered with a suitable self-levelling compound before tiling. This protects the heating system, creates a flat surface and makes tile installation much easier. Always follow the manufacturer’s installation guidelines for the specific heating system and flooring materials being used.

Yes, in most installations a primer is recommended before applying self-levelling compound or tile adhesive. Primers improve adhesion, reduce dust on porous surfaces and help ensure a strong, long-lasting bond between the subfloor and the levelling compound or adhesive.

Yes. Self-levelling compound is specifically designed to flow over electric underfloor heating mats and cables, fully encapsulating them and creating a smooth, durable surface ready for the final floor covering. Using a suitable flexible levelling compound also helps protect the heating elements during installation.

The required thickness depends on the product being used and the installation. In most underfloor heating applications, the compound is applied just thick enough to fully cover the heating cables or mats, although some products are suitable for thicker applications if required. Always follow the manufacturer’s recommendations for minimum and maximum depths.

No. Standard tile adhesive is generally not recommended for use with underfloor heating because it cannot accommodate the movement caused by repeated heating and cooling cycles. A high-quality flexible tile adhesive should always be used to provide a durable, long-lasting installation.

Many flexible tile adhesives, primers and self-levelling compounds are suitable for wet rooms, bathrooms and shower areas when installed correctly. For these environments, choose products specifically designed for high-moisture applications and ensure the floor has been properly waterproofed where required. If you’re unsure which products are best for your project, the Hydaheat team can provide expert advice.

Unlike standard tile adhesives, they help reduce the risk of cracking and ensure a strong, long-lasting bond between the floor covering and the subfloor.
