HB42 Ultimate LXP Stix Foam is ultra-low expansion polyurethane foam, perfect for bonding plasterboard, Styrofoam, XPS, EPS insulation boards and more.

Ultra Low Expansion means it doesn’t rise or expand as much as the other foam, making it less permeable to air and moisture and therefore supremely strong.

HB42 is not only ultra low expansion, but also has a Unique Start / Stop Valve which stops it from curing in the can, so you can pick it up and use again, and most importantly waste less!* *the straw will still have to be cleaned out each time.
