Yes, it is designed for brickwork and blockwork expansion joints, making it suitable for both interior and exterior applications where joint filling and sealing are required.

The tear-off strip is a guide for applying mastic sealant. Once the foam strip is in place, you tear off the strip to create a clean edge, allowing for precise and neat application of sealant over the foam.

The foam has low moisture absorption due to its closed-cell structure, which helps prevent water ingress. However, for a fully waterproof seal, it must be used in conjunction with an appropriate mastic sealant applied over it.

You can easily cut the foam strip to your required length using a sharp utility knife or a suitable cutting tool. Ensure a clean, straight cut for best results.

It is ideal for both commercial and residential projects, specifically for filling expansion joints in brickwork and blockwork.

Ensure the joint is clean and free of debris. If the joint is slightly narrower than the foam, compress the foam gently as you insert it. For slightly wider joints, consider a thicker variant if available.

Ensure the sealant has not adhered to the strip. If it's sticking, try a slightly different angle or use a fine blade to carefully score along the edge before pulling.

This is unlikely with polyethylene foam. Ensure the foam has not been exposed to excessive solvents or heat. If the product is defective, contact your supplier.

Ensure the surface of the foam (after removing the tear-off strip) and the adjacent substrate are clean, dry, and free from dust or contaminants before applying sealant.
