EshaPrimer is a quick drying black bitumen priming solution designed to penetrate and seal a variety of porous surfaces including masonry, concrete, cementitious screed/renders, existing bituminous waterproofing and structural steelwork. EshaPrimer creates a base seal and improves the adhesion of bituminous waterproofing solutions.
EshaPrimer is a mixture consisting high quality bitumen’s and hydrocarbon solvents.
The substrate must be clean and dry, structurally sound and free from laitance, oils, dirt, moss, lichen and loose materials. If applied to an existing roofing membrane the surface must be quite smooth.
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.
EshaPrimer requires between 1 and 4 hours to completely dry. EshaPrimer must be completely dry before applying the bitumen membrane. For additional protection two layers can be used.
Apply as stated only when atmospheric and substrate temperatures are greater than 5 °C. Below this temperature ensure the primer has cured and dried before applying PermaQuik Hot Melt or EshaFlex RBM waterproofing, and if needed heat the surface prior to applying the waterproofing.
