Application Methodology
Preparation of Surface
Surface must be clean, dry and free of grease, oil and painting compound. Concrete surface must be dry and stable for (at least) four weeks. Users must check that the sealant is compatible with surface in terms of adhesiveness, staining and chemical compatibility. Making the Joint If necessary, apply a thin layer of PU Primer on the surface. After the Primer has dried press flexible non adhesive filler on the groove. The joint filler should be free of holes to ensure that bubbles do not form in the joint. For better finish use protection strip. For a narrow joint apply the sealant in one movement. For very wide joint apply the sealant in three places: The first two on the edges of the joint and third in the joint filler. Smooth out with soapy water. Press the sealant against the edges and the joint and joint filler while taking care not to create air bubbles. Remove protection strip. Clean the equipment with solvent like Xylene, Toluene. Polymerised sealant can be scrapped off. May be painted after polymerisation is complete. Use acrylic or vinyl dispersion paints after testing a section.
