Compriband 20/4 Sealing Tape 8 m Roll Anthracite 20 mm Width Joint Width 4–20 mm Self-Adhesive & Expanding Swelling Tape For Indoor & Outdoor Use

We have a sizeable gap at the bottom of our Motorhome door and this expanded very quickly to fill it. As I’ve only used a foot or so there’s plenty left should we need to replace it. Very easy to apply as sticky tape.

Gives a draught proof seal for a variable gap between brickwork and window/door frame, and lasts for years.

I applied it between my skirting board and floorboards. It adhered easily and has expanded to fill the gap really effectively and stopped the considerable draught. The slow expansion gives plenty of time to get it into small gaps.

Took a while to expand as it was a cold day but made a great seal when it did , nice clean finish

Top product.

Just the job for filling tight fitting gaps before sealant, I used it around doors in a timber frame building and the slow expansion helped during the installation

Excellent product that is easy to apply and so far has weatherproofed glazing panels.

Does what it says
