High Bond Polymer Primer is a quick drying green synthetic rubber based primer for use with hot melt waterproofing systems designed to penetrate and seal a variety of porous surfaces including masonry, concrete, cementitious screed/renders, existing waterproofing and structural steelwork. High Bond Polymer Primer creates a base seal and improves the adhesion of hot melt waterproofing solutions.
• The substrate must be clean and dry, structurally sound and free from laitance, oils, dirt, moss, lichen and loose materials.
• Apply by brush or roller ensuring the primer is well applied into the surface. Apply a thin coat and avoid pooling. Allow to dry thoroughly before over coating. Ensure ventilation is sufficient.
• High Bond Polymer Primer requires between 15-30 minutes to dry, with a working time of 4 hours.
• High Bond Polymer Primer must be completely dry before applying hot melt membrane.
