Features and Benefits

Micro Prime (E) can be applied to wet or damp surfaces free from running or ponding water. It is safe to use on freshly laid hardened (green) concrete and consolidates weak or rain-affected concrete surfaces, forming a firm substrate for subsequent treatments. It has excellent penetration, even into fine-grained substrates such as high-strength concrete. The product is tolerant to improperly prepared surfaces, seals and binds dusty or loosely bound surfaces, and offers excellent adhesion to most substrates, including brick, masonry, concrete block, concrete, compressed fibreboard, stone, and timber. Non-flammable with negligible odour, it offers a convenient equal part mixing ratio and is water-thinned for easy clean-up. Safe to use in sensitive locations such as around food or habitable areas.

Typical Uses

Micro Prime (E) is used as a penetrating sealer to achieve bonding to high-strength concrete or other fine-textured surfaces. It serves as a consolidation sealer for weak aged concrete prior to over-coating with other covering or coating systems. The product is also effective as a bonding coating for surfaces where there is a risk of grease or oil in the surface, a consolidation sealer for rain-affected concrete to form a firm substrate, and as a waterproofing sealer for concrete, masonry, brickwork, fibre cement, plywood, and particleboard in wet areas. It is also used as an industrial dust suppressant and sealer for warehouse and factory floors where colour is not critical.

Limitations

Micro Prime (E) should not be applied when the surface temperature is below 8°C or above 35°C, or when the relative humidity is above 90%. The curing reaction will cease at temperatures below 8°C and will recommence slowly as the temperature rises above 8°C. Good ventilation is required during the drying and curing cycle. The product is not stable under ultra-violet light unless under water and is only trafficable when used as a sealer. Do not sandwich water or solvent-based adhesives between Micro Prime (E) and low permeability floor coverings.

Application Methodology

All surfaces to be treated should be structurally sound and thoroughly cleaned, free from all surface contaminants. Remove all existing coatings before applying Micro Prime (E). The pores of the concrete should be opened as much as possible by high-pressure water blasting or abrasive blast cleaning. Ensure all concrete curing membranes or form release agents are thoroughly removed before application.
