Epoxy/PU floorings cannot be carried over construction and expansion joints. Industrial floor joints may require careful attention while filling. A variety of polysulphide, rigid and urethane joint sealants are available, to be applied on different joints under different conditions. Urethane floor joints are available in a wide range of colors to match with existing flooring systems and can be applied on non movable joints. Joints in between tiles, kota stone, mandana stone etc. can be filled with chemical resistant epoxy putty, otherwise the chemicals and acids spills on the floor and spreads to the beneath of tiles and stones through.
