Soudal Gap Filler Expanding Foam

Soudal Gap Filler Expanding Foam is a moisture curing polyurethane expanding foam which is used for all general purpose gap filling. Soudal Gap Filler Expanding Foam adheres to most common building materials and is resistant to water, heat and ageing.

Soudal Gap Filler Expanding Foam has excellent thermal and acoustic insulation values.  It can be cut, sanded, painted or plastered after full cure.

Soudal Gap Filler Expanding Foam is not UV Resistant, therefore the product must be covered with a sealant, paint or plaster once cured.

Genius Gun® Application:

This product utilises the Genius Gun®.

The Genius Gun® is the ideal application system for PU Expanding Foams that do not require an applicator gun, offering ease of use and maximum performance.

The combination of professional quality products with easy usability is an ideal solution.
