A stretchy adhesive and sealant for joints that move, so the bead flexes with the timber, metal or tile instead of cracking away from it.
T-Rex Flex is Soudal's SMX hybrid polymer, and once it cures it stretches to 750% and stays elastic and waterproof. It bonds most building materials, even if they're slightly damp, it's paintable with water based paint, and it has a mould resistant additive for wet areas. It has no smell and no solvents. It won't stick to polyethylene, polypropylene or Teflon, and Soudal say to keep it off copper, brass and bronze. Steel grey suits metal, concrete and grey joints.
One 290ml cartridge, and it needs a caulking gun. Full specs are in the tabs below, or call us on (08) 8536 4333 or come in and chat with us at 34-52 Milnes Rd, Strathalbyn.
