Gripset E60: A Technical Overview
Gripset E60 is a two-component, water-based epoxy primer and moisture/vapour barrier, engineered for high-performance sealing of mineral substrates. Suitable for both internal and external applications, E60 can be applied to damp and newly poured concrete without compromising adhesion. With hydrostatic pressure resistance up to 2.5 bar (≈25 m water head) and water vapour transmission as low as 1.3 g/m²/24h (ASTM E96), it provides a reliable defence against rising damp and efflorescence. AS 4020 compliance ensures safety in potable water applications, making it ideal for tanks, pools, and water-retaining structures. Once cured, it forms a dense, non-flammable, odourless barrier compatible with Gripset membranes, adhesives, and coatings.

Proactive Troubleshooting
Scenario: Applying over surfaces with standing water
Potential Outcome: Poor adhesion, blistering, or incomplete curing.
Adheseal Best Practice: Remove all standing water and address running water with Gripset C-Plug prior to application.
Scenario: Coating beyond 72 hours without overcoating
Potential Outcome: Reduced bond strength for subsequent layers.
Adheseal Best Practice: Overcoat within 72 hours or lightly sand the surface and reapply a fresh coat of E60 before proceeding.
Applications in Practice: Trade Scenarios
For Waterproofers (Specifier/Engineer): Vapour Barrier Under Membranes
The Professional's Challenge
Preventing membrane failure when applied over damp concrete with high moisture vapour emissions.
The Adheseal Solution: Engineered Certainty in Practice
Apply a single coat of Gripset E60 at 1 L/3 m² to form a 150 μm dry film, reducing vapour transmission to 1.3 g/m²/24h before membrane installation.
Best Practice Note
Lightly dampen porous concrete before application to improve penetration and adhesion.
For Builders (Business Owner/Operator): Rising Damp Prevention
The Professional's Challenge
Avoiding costly remediation caused by moisture migration through slabs into finishes.
The Adheseal Solution: Engineered Certainty in Practice
Apply two coats of Gripset E60 at 1 L/3 m² per coat for a 300 μm total dry film, blocking moisture ingress and preventing efflorescence.
Best Practice Note
Broadcast fine dry sand into the second coat while wet to create a keyed surface for screeds or adhesives.
For Tilers (On-Site Applicator/Installer): Direct Tiling Over E60
The Professional's Challenge
Ensuring tile adhesion over a non-porous moisture barrier without bond loss.
The Adheseal Solution: Engineered Certainty in Practice
After applying two coats of E60, sand seed the wet second coat at 750 g/m² to achieve at least 90% coverage, then sweep/vacuum excess sand before tiling.
Best Practice Note
Ensure the sand is clean, dry, and fine grade to maximise adhesive bond to the E60 surface.
Frequently Asked Questions
Can Gripset E60 be applied to damp or green concrete?
Yes. Gripset E60 can be applied to damp and “green” concrete without compromising adhesion. This allows early installation of waterproofing, adhesives, or coatings without waiting for full concrete curing.
What is the hydrostatic pressure resistance of Gripset E60?
Gripset E60 can withstand up to 2.5 bar of hydrostatic pressure, equivalent to approximately 25 metres of water head, making it suitable for potable water tanks and submerged structures.
How soon can I overcoat E60 with membranes or adhesives?
You can overcoat E60 after 24 hours at 23°C and 50% RH. For optimal bonding, overcoat within 72 hours of curing; otherwise, lightly sand and recoat before proceeding.
Can E60 be used in potable water applications?
Yes. Gripset E60 is AS 4020 compliant, meaning it is suitable for use in potable water storage without affecting water taste or quality. Always wash the cured surface before filling tanks.
What is the pot life of Gripset E60 once mixed?
The mixed product has a pot life of approximately 2 hours at 23°C. Only mix the quantity you can apply within this time to avoid waste.

Application Guide – Step-by-Step
1. Surface Preparation
- Ensure all surfaces are clean, sound, and free of laitance, dust, oil, grease, curing agents, or other contaminants. Mechanical preparation may be required for weak or contaminated surfaces.
- On porous or aged concrete, lightly mist with clean water immediately before application to improve penetration.
- Remove any standing or running water before coating. Seal active leaks with Gripset C-Plug prior to priming.
2. Mixing
- Mix Part A and Part B in a clean container using a slow-speed mechanical stirrer (< 300 rpm) for at least 2 minutes until uniform.
- Scrape sides and base during mixing to ensure consistency.
- Do not thin except where specified for first-coat penetration on porous/dense surfaces (max 5–10% clean water).
- Only mix the quantity you can use within the pot life (~2 hours at 23°C).
3. Priming & First Coat Application
- Apply first coat using a squeegee, stiff nylon broom, or medium/long-nap roller, working the product into pinholes and surface voids.
- For general priming: apply at 1 L/10 m² (≈100 µm WFT / 50 µm DFT).
- For vapour barrier: apply at 1 L/3 m² (≈300 µm WFT / 150 µm DFT).
- For moisture barrier: apply 2 coats at 1 L/3 m² each, ensuring total ≈300 µm DFT.
4. Second Coat / Build-Up
- Allow first coat to dry for approximately 4–6 hours (at 23°C, 50% RH) before applying second coat.
- Apply second coat at the same coverage rate as the first for barrier builds.
- For tiling or toppings: while second coat is wet, broadcast fine dry sand (≈750 g/m²) to achieve ≥90% coverage. Once dry, sweep/vacuum excess sand.
5. Overcoating & Curing
- Overcoat with compatible membranes, adhesives, or coatings after 24 hours (at 23°C, 50% RH).
- Overcoat within 72 hours for optimal bonding. If exceeded, lightly sand the surface and apply a fresh coat before proceeding.
- For immersion service, allow a minimum of 7 days curing before filling with water.
6. Clean-Up
- Clean tools and equipment immediately after use with water while product is still wet.
- Once cured, E60 can only be removed mechanically.
Limitations & Safety
Limitations
- Do not apply in temperatures below 10°C or above 35°C, or if rain or condensation is likely before cure.
- Not suitable for application over surfaces with active water leaks — seal leaks first with Gripset C-Plug.
- Avoid application to contaminated, friable, or unprepared surfaces — mechanical preparation may be required.
- Not designed as a wearing surface — must be overcoated, tiled, or finished with a compatible system unless used as an internal tank lining.
- When broadcasting sand for tiling, ensure ≥90% coverage is achieved for reliable adhesive bond.
Safety
- Wear appropriate PPE including gloves, safety glasses, and protective clothing during mixing and application.
- Avoid skin and eye contact; in case of contact, rinse immediately with clean water and seek medical advice if irritation persists.
- Use in well-ventilated areas; avoid inhaling vapour or mist during application.
- Do not ingest; if swallowed, rinse mouth and seek urgent medical attention.
- Refer to the current Safety Data Sheet (SDS) for detailed handling, storage, and first aid information.
