Soudal Gun Grade Expanding Fixing Foam 750ml

Soudal's gun grade expanding foam is a moisture curing, self-expanding polyurethane foam for general purpose fixing, filling, and insulating. It adheres to all common building materials and is resistant to water, heat, and ageing, with excellent thermal and acoustic insulation values.

This is the trade-standard gun grade foam used across the UK construction industry for fixing and insulating door and window frames, filling holes and gaps, insulating around pipes and electrical wiring, and securing wall panels, corrugated sheets, and roof tiles. It delivers high yield expansion from the 750ml canister.

Once fully cured, the foam can be cut, sanded, plastered, and painted. It is not UV resistant, so exposed foam should be covered with sealant, paint, or cladding after curing. Requires a standard PU foam applicator gun.
