GLADIATOR PUR 241 is a tanned colour thrixotropic gel one part moisture curing polyurethane fully waterproof assembly and repair adhesive for the joinery and construction industry which has a skin formation time of 5 minutes.

It provides excellent bonding strength on wood and most construction materials including rubber, concrete and thermal insulation materials.

It foams slightly on application to fill small gaps, which increases bond strength.
