Adhesives

Adhesives provide a strong, durable bond for various materials like tile, stone, and wood. They are versatile, easy to apply, and offer moisture and heat resistance, making them ideal for areas with temperature changes or humidity. Quick-setting options also speed up project completion and ensure a smooth, lasting finish.

Levellers

Levellers create a flat, even surface essential for proper flooring installation. They fill cracks and imperfections, ensuring a stable base that enhances adhesion and prevents future issues. Compatible with various flooring types, levellers save time with fast-setting options and improve the durability of the finished floor.

Compatibility Considerations

Compatibility Considerations

  • Adhesives and levelling compounds must be compatible with heating systems.
  • Must accommodate thermal expansion and contraction from temperature changes.
  • Use flexible, heat-resistant adhesives to prevent cracking over time.
  • Levelling compounds should be designed to withstand heat without compromising integrity.

What adhesive should I use for underfloor heating?

The best adhesive to use for underfloor heating will be an adhesive that has been coded with either S1 or S2. This code that appears on the packaging of any applicable adhesive indicates that the adhesive is a deformable adhesive which means it can withstand movement - such as the expanding and contracting of floors where underfloor heating has been installed.

How much adhesive do I need over electric underfloor heating?

For electric underfloor heating, it is advised to provide 1.8kgs per 1mm depth per m2 of adhesive. This ensures that there is enough adhesive to form a strong bond with the components of the underfloor heating system. You can find out more information on our dedicated 'How Much Adhesive Do I Need?' guide.

Do you need flexible tile adhesive for underfloor heating?

It is advised to use flexible tile adhesive for underfloor heating, or a tile adhesive that has been coded with either S1 or S2.
