The smoothable adhesive for floor and wall bonding

Thanks to our 645 Flächen Kleber, wall and floor coverings stay in place immediately without slipping. This adhesive bonds shortly after it has been applied and is extra-easy to use thanks to its one-component composition. It also cures with virtually no shrinkage. The MS hybrid adhesive is water and solvent-free and does not cause any wood swelling or damage to solvent-sensitive materials. 645 Flächen Kleber is permanently elastic and tension-equalising. It reliably creates bonds on a wide variety of materials such as wood, concrete, metal, plastic and even enamelled glass. With the approvals it has received and tests it has passed, the adhesive is also ideal for bonding wall coverings in the food industry. Plus, because it is odourless, it is a great choice for interior fitting and finishing.
