Soudal B3 Gap Filler Expanding Foam Hand Held 750ml

Soudal B3 Gap Filler Expanding Foam Hand Held 750ml is a versatile, moisture-curing polyurethane expanding foam designed for general-purpose filling, sealing and insulating applications. Suitable for both interior and exterior construction work, it provides excellent adhesion to many common building materials while expanding to efficiently fill holes, voids, gaps and joints.

The self-expanding formula provides a high filling yield, making it particularly useful for sealing difficult-to-reach spaces and irregular gaps. Once cured, the foam provides effective thermal and acoustic insulation, helping reduce heat loss and sound transmission around openings and penetrations.

Soudal B3 Expanding Foam is ideal for filling and insulating around window and door frames, as well as sealing gaps around pipes, electrical wiring and other common building applications. Its resistance to water, heat and ageing helps provide a durable, long-lasting result.

Once fully cured, the foam can be cut, sanded, plastered and painted, allowing excess material to be easily trimmed and finished for a neat, professional appearance.

Supplied in a convenient 750ml hand-held can, Soudal B3 Gap Filler is an excellent general-purpose expanding foam for professional tradespeople, construction work, maintenance and DIY applications.
