T Rex Power Floor & Wall SMX Tub 4kg

Soudal T Rex Power Floor & Wall SMX Adhesive Tub 4kg

Soudal T Rex Power Floor & Wall SMX Adhesive is a high-performance, single-component construction adhesive designed for full-surface bonding of floor and wall coverings.

Supplied in a 4kg white tub, this trowelable adhesive is based on advanced SMX® polymer technology, making it chemically neutral, fully elastic and extremely strong. It provides outstanding adhesion to both porous and non-porous substrates, including concrete, screed, existing tiles, natural stone, stainless steel, timber panels and many common building materials.

This adhesive is formulated for both horizontal applications (floor tiles, natural stone tiles, vinyl or textile floor coverings, carpet, etc.) and vertical applications (wall tiles, panels, splashbacks, stainless steel panels). It can even be applied to slightly damp substrates and is suitable for many sanitary and wet-area applications when used as directed. 

Unlike solvent-based adhesives, T Rex Power Floor & Wall is free from isocyanates, solvents, halogens and acids, offering excellent indoor air quality and improved safety for installers. It remains permanently flexible, accommodating movement up to approximately ±20%, and will not stain sensitive materials such as marble, granite or other natural stones.

T Rex Power Floor & Wall FAQs

Frequently Asked Questions

Q1: What surfaces can T Rex Power Floor & Wall be used on?
It bonds to most common construction substrates, including concrete, screed, existing tiles, natural stone, stainless steel, timber panels and many other porous and non-porous surfaces. Always ensure surfaces are sound, clean and properly prepared.

Q2: Is it suitable for natural stone tiles?
Yes. The adhesive is non-staining and is specifically formulated so it does not migrate into or stain porous materials such as marble and granite when applied correctly.

Q3: Can I use it in wet areas like bathrooms?
Yes, it can be used on slightly damp substrates and is suitable for many sanitary and wet-area applications, provided that the substrate and waterproofing system are correctly designed and installed.

Q4: Is it flexible once cured?
Yes. Once cured, the adhesive forms a flexible, rubber-like bond that can accommodate movement up to about ±20%, reducing the risk of tile or panel debonding.

Q5: Can I paint over T Rex Power Floor & Wall?
It is paintable after full cure, but due to the variety of paint types, a small compatibility test is recommended before full application. 

Q6: Is it safe to use indoors?
Yes. Being free from solvents, isocyanates, halogens and acids, it has minimal health and safety considerations when used as directed and in well-ventilated areas. 

Q7: How is it applied?
Apply with a notched or flat adhesive trowel at approximately 60° to the substrate, ensuring full contact with the back of the tile or panel. Refer to the TDS for detailed application and consumption guidelines.
