The PU 1K / PUP 1K universal polyurethane foam from Fischer is a one-component foam for general construction use. Supplied in a 750 ml yellow spray can, it delivers a free-foam yield of 35 litres and fills, seals and insulates gaps, joints and cavities. It has a declared shelf life of 18 months and is sold in single packs, in versions that can be dispensed with a gun or a straw.
Polyurethane foam is an expanding sealant and adhesive in a can for filling gaps, fixing frames and bonding insulation panels and plasterboard.
What it is for

How to use it
Shake the can thoroughly, clean and lightly moisten the substrate and fit the can to the foam gun or adaptor. When filling, dispense leaving room for expansion; to bond panels, apply a bead to the panel, position it and hold it in place for the stated time. After curing, trim off the excess with a utility knife and clean the gun with foam cleaner.
