External roofs, balconies, and plant areas demand a finish that stands up to constant UV exposure and light foot traffic without compromising safety. Gripset LS provides the essential hard-wearing, non-slip top coat, engineered to enhance the durability and performance of underlying waterproofing membranes. It delivers a safe, weather-resistant surface where pedestrian access is required, ensuring long-term protection and peace of mind on exposed outdoor areas.
Gripset LS is formulated as a robust, non-slip, UV-stable finish coat, specifically for application over suitable Gripset liquid waterproofing membranes. Its purpose is to fortify the waterproofing system, providing an additional layer of protection against the elements and light pedestrian traffic. This top coat is not a standalone waterproofing membrane, but an integral part of a durable system, prolonging the life of the underlying membrane by shielding it from environmental stressors and providing a safe, trafficable surface.
Gripset LS applies directly over a cured Gripset base liquid membrane such as Gripset 38FC, P39, or Xpress Multi Pro. Surfaces must be clean, sound, and dry. Mechanically remove any loose material or contaminants. Fill voids or non-structural cracks with products like Gripset 11Y or other RLA repair mortars. Concrete requires 28 days of cure, while cement render or screeds need 7 days.
Apply Gripset LS by brush or medium nap roller. For optimal performance, a minimum of two coats is required, achieving a total dry film thickness of 1.0 mm (1.5 litres/m²). For enhanced durability in higher wear areas, a third coat can be applied to reach 1.5 mm dry film thickness (2.0 litres/m² total). Apply subsequent coats in alternating directions and use a wet film gauge to ensure correct coverage and film build. Recoat after 4 hours, allowing 24 hours for light foot traffic and 10 days for full cure, noting that cooler or humid conditions will extend these times. Clean tools with water while the product is still wet; dried material requires mechanical removal.
Gripset LS is regularly specified for projects demanding durable, slip-resistant, and UV-stable finishes over waterproofing membranes:
Gripset LS functions as the final, exposed layer within a comprehensive waterproofing system. Real-world specifications consistently show it applied as the last step in sequences designed for concrete roofs, mezzanine plant areas, and parapets. A typical system begins with a suitable primer, such as a two-part epoxy damp concrete primer, followed by a primary liquid waterproofing membrane like Everflex WPUV UV-Stable Waterproofing Membrane. Gripset LS then forms the durable, non-slip, UV-resistant top layer, completing the system and protecting the underlying membrane from environmental wear and tear.
This product is classified as a non-hazardous chemical. For safe handling, always refer to the Safety Data Sheet (SDS) and wear appropriate personal protective equipment, including safety shoes, overalls, gloves, and safety glasses.
Gripset LS is designed for external floor surfaces on rooftops, podiums, balconies, and walkways. It functions as a hard-wearing, non-slip finish coat over a suitable Gripset liquid base membrane system.
No, Gripset LS is not an elastomeric crack bridging membrane. It must be applied over a suitable Gripset base liquid membrane system like Gripset P-39 or Xpress Multi Pro, which handle substrate movement.
Gripset LS is suitable for light foot traffic only. It is not designed for vehicular traffic or commercial foot traffic, which require different surface solutions.
Apply a minimum of two coats for a 1.0 mm dry film thickness at 1.5 litres/m². For enhanced durability, apply a third coat to achieve 1.5 mm dry film thickness at 2 litres/m² total coverage.
Gripset LS is ready for light foot traffic after 24 hours. Full cure, including suitability for flood testing, is achieved after 10 days. Recoat time between coats is 4 hours, all at 23°C and 50% RH.
| Application | Key benefit | Primary trades |
|---|---|---|
| External rooftops | Provides a UV-stable, non-slip, hard-wearing finish over a base membrane, resisting ponding water and fungi. | Waterproofers, roofers, builders |
| Decks and balconies | Offers a durable, foot trafficable, non-slip surface, enhancing safety and extending the life of the underlying waterproofing. | Waterproofers, builders, tilers |
| Exposed rooftop plant/maintenance areas | Protects waterproofing from light foot traffic, UV exposure, and environmental elements in service areas. | Facility managers, waterproofers |
| Walkways and podiums | Creates a resilient, non-slip pedestrian surface, preventing premature wear and tear on membrane systems. | Waterproofers, landscapers, builders |
Ensure substrate is part of a fully cured Gripset membrane system (P39, 38FC, or Xpress Multi Pro). The membrane must be clean, dry, and free from contaminants.
Follow the primer and base membrane application requirements of the selected Gripset system before top coating with LS.
Apply by brush or medium nap roller in two or three coats, with each coat applied perpendicular to the previous.
2 coats at a total of 1.5 L/m² for 1mm dry film thickness.
3 coats at a total of 2 L/m² for 1.5mm dry film thickness.
Gripset LS is classified as a non-hazardous chemical. However, standard safety precautions should be followed during handling and application.
For general use, wear safety shoes, overalls, nitrile rubber gloves (for intermittent contact), and safety glasses.
Ensure good general ventilation in the work area. Avoid inhalation of vapour, mist, or aerosols.
Store in original unopened packaging in a cool, dry, well-ventilated place, out of direct sunlight and away from foodstuffs or incompatible materials. Avoid freezing conditions. Shelf life is 12 months. Material and containers should be recycled where possible; otherwise, dispose of according to local regulations.
Proper substrate preparation is critical for Gripset LS to bond correctly and achieve its stated performance, ensuring long-term system integrity.
Surface prep: All surfaces must be clean, sound, dry, and free from contaminants like dust, oil, grease, and curing compounds. Mechanically remove unsound layers by grinding or abrasive blasting. Point masonry surfaces flush and fill all defects, voids, and non-structural cracks. Concrete requires a minimum 28-day cure, and cement render/screeds need 7 days.
Primer: Not required for Gripset LS itself. This product is applied over a suitable Gripset base liquid membrane system (e.g., Gripset 38FC, P39, Xpress Multi Pro) that has its own specific primer requirements.
Surface prep: Ensure surfaces are clean, dry, and free from any loose material or contaminants. Building surfaces must be fit for purpose and installed to manufacturer recommendations.
Primer: Not required for Gripset LS. Apply over a suitable Gripset base liquid membrane system.
Surface prep: Surfaces must be clean, dry, and free of defects or contaminants. Ensure plywood is exterior grade and installed correctly.
Primer: Not required for Gripset LS. Apply over a suitable Gripset base liquid membrane system.
Surface prep: Tiles and pavers must be well bonded, clean, and free from loose material, dirt, dust, oil, or any residues. Mechanically prepare to ensure adequate adhesion.
Primer: Not required for Gripset LS. Apply over a suitable Gripset base liquid membrane system.
