For external rooftops, decks, balconies, and walkways where a slip-resistant, weather-exposed finish is required, Gripset LS Trafficable Coating provides a hard-wearing top coat that withstands light foot traffic and permanent UV exposure. This solvent-free, non-shrinking formulation applies over suitable base liquid membranes to protect the underlying waterproofing system from climatic wear without requiring sand casting or aggregate additions.
Gripset LS Trafficable Coating acts as a protective, light grey, non-slip finish coat over base liquid membranes on substrates such as concrete, screeds, compressed fibre cement sheeting, exterior grade plywood, and well-bonded existing tiles or pavers. It is flexible to accommodate thermal movement, though it is non-elastomeric and must not be used as a standalone crack-bridging membrane on suspended areas. It resists algae and fungi growth, prevents water ponding degradation, and can be built up in high-film thicknesses to increase long-term durability on exposed service areas and maintenance walkways.
All substrates must be clean, dry, and free from surface contaminants such as curing compounds, laitance, or existing failed coatings. Concrete must cure for a minimum of 28 days, and screeds or sand-cement renders for 7 days. Apply the product by brush or medium nap roller. Apply the first coat at 750 microns wet film thickness (10m² coverage per 15-litre pail) and allow to dry for 4 hours. Apply the second coat at right angles to the first coat to ensure complete, pinhole-free coverage. Use a wet film gauge during application to verify and regulate consistent film build across the entire surface area. Clean up tools and spills with water while the coating is wet; dried material must be removed mechanically.
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.

Surface prep: Surfaces must be clean, dry, and free of defects or contaminants. Ensure plywood is exterior grade and installed correctly.
