When dealing with chronically damp or green mineral surfaces, establishing a dry, bondable substrate is critical. Gripset E-60 transforms these challenging environments. This two-component epoxy creates a powerful moisture and vapour barrier, preparing surfaces for subsequent coatings and finishes with confidence. It allows for immediate progress on jobs that would otherwise be stalled by moisture issues.
Gripset E-60 provides a multi-functional foundation where moisture is a significant concern. It functions as a heavy-duty moisture and vapour barrier, a high-performance primer, and a protective coating. It addresses the core problem of moisture penetration and rising damp through mineral surfaces, effectively resisting hydrostatic pressure and preventing efflorescence. This formulation ensures that subsequent layers like membranes, adhesives, and floor finishes bond reliably, even on difficult substrates like 'green' concrete.
Its ability to withstand up to 25 metres or 250 Kpa of hydrostatic pressure is a key performance indicator. This ensures the barrier remains effective against significant water ingress, preventing delamination and failure of subsequent finishes. A low water vapour transmission rate of 1.3 g/m²/24 hours (at 300-micron dry film thickness) means it significantly reduces moisture vapour movement, allowing for earlier installation of moisture-sensitive floor coverings. The 2-hour pot life offers a practical working window, while a 4-hour recoat time optimises workflow on site, balancing usability with rapid progression.
Gripset E-60 is a two-component product, requiring equal parts of A and B to be thoroughly mixed for approximately 3 minutes. For optimal penetration into porous or dense substrates, the first coat can be diluted with a small amount of water. Application is versatile; use a squeegee, stiff nylon broom, or medium/long nap roller on floors, ensuring consistent coverage to fill pinholes and voids. For vertical surfaces, a medium-long nap roller is recommended. If tiling or applying cementitious toppings, the second coat of E-60 must be sand-seeded at 750g/m² to create a mechanical key for superior adhesion. Tools and equipment should be cleaned with water while the product is still wet; dried material requires mechanical removal.
Gripset E-60 serves as a critical foundational layer on mineral surfaces where moisture management is paramount. It is typically the first step on prepared concrete, screed, or masonry that exhibits dampness or is 'green'. For example, before installing liquid or sheet waterproofing membranes (like Gripset 2P Waterproofing Membrane or Gripset P39 Waterproofing Membrane) on a concrete slab, E-60 establishes a dry, stable base. For direct tiling with products like Gripset C-Rubber Tile Adhesive, applying two coats of E-60 with a sand-seeded second coat provides the necessary moisture barrier and mechanical key for durable tile adhesion.
Gripset E-60 is a heavy-duty, two-component, water-based epoxy solution engineered for significant moisture challenges, including direct hydrostatic pressure and 'green' concrete. Its robust formulation provides a multi-functional moisture and vapour barrier. In contrast, Gripset Xpress Primer H2O Plus is a single-part, rapid-drying primer better suited for managing residual surface moisture and general adhesion promotion on porous and non-porous surfaces where hydrostatic pressure resistance is not a primary requirement. Choose E-60 for serious, structural moisture issues; opt for Xpress Primer H2O Plus for everyday priming and moisture mitigation where extreme conditions are not present.
Yes, Gripset E-60 is designed for application on damp and green concrete. This allows for earlier project commencement and eliminates extended drying times before applying subsequent finishes.
Gripset E-60 can resist up to 2.5 bar (250 kPa) of hydrostatic pressure. This makes it suitable for negative moisture and rising damp applications where significant water pressure is present.
Yes, Gripset E-60 complies with AS 4020 for potable water storage applications. Ensure the cured surface is washed down and dispelled before filling the tank for use.
No, Gripset E-60 is not designed as a trafficable coating or for permanent UV exposure. It functions as a primer, moisture barrier, or protective undercoat for other finishes.

Wear safety shoes, overalls, gloves (nitrile rubber recommended), and chemical goggles. Use an organic vapour/particulate respirator if an inhalation risk exists. Wash hands thoroughly after handling and before eating, drinking, or smoking.
Ensure adequate natural ventilation in the work area. If necessary, increase ventilation to manage vapours and aerosols.
Store in original, unopened packaging in a cool, dry, well-ventilated area, away from direct sunlight and foodstuffs. Avoid freezing. Shelf life is 12 months. Dispose of contents and container according to local, regional, and national regulations.
Proper surface preparation is critical for the adhesion and long-term performance of Gripset E-60. Ensure all surfaces are clean, sound, and free from contaminants.
Surface prep: Concrete must be free from laitance, curing compounds, and loose material. Mechanically remove unsound layers by grinding or abrasive blasting. Concrete should cure for at least 28 days, though E-60 can be applied to green concrete.
Primer: Not required, as E-60 serves as the primary coating. Dilute the first coat with 5-10% water depending on porosity to aid penetration.
Surface prep: Allow cement render/sand cement screeds to cure for at least 7 days. Ensure surfaces are smooth, level, and free of defects. Fill voids and non-structural cracks.
Primer: Not required. Dilute the first coat with 5-10% water depending on porosity to aid penetration.
Surface prep: Masonry surfaces require pointing flush. Fill all surface defects including voids, holes, and pitted sections before application.
Primer: Not required. Dilute the first coat with 5-10% water depending on porosity to aid penetration.
Surface prep: Ensure sheeting is clean, dry, and installed according to manufacturer's recommendations and relevant building standards.
Primer: Not required, E-60 acts as the adhesion enhancer for subsequent systems.
