Gripset LS Roof Coat - Non-Slip Top Coat for External Roof Surfaces


Gripset LS Roof Coat is a hard-wearing, non-slip top coat specifically designed for external floor surfaces on pitched or flat roofs, podiums, and balcony areas. It serves as the finish coat over other Gripset base liquid membranes or GC2 sheets, creating a durable membrane system for applications exposed to permanent exposure, varying climatic conditions, UV light, and foot traffic.

Product Characteristics:

  • Size: 15 Litre

Features & Benefits

  • Solvent-free and non-hazardous
  • Non-shrinking, flexible (not elastomeric)
  • Resistant to fungi and algae growth
  • Excellent weathering properties
  • Excellent adhesion to surfaces
  • Excellent ponding water resistance
  • Foot trafficable
  • Can be applied in high-build film thickness for greater durability

Waterproofing Uses

Gripset LS Roof Coat can be used for the following waterproofing applications:

  • Roof areas (used with a base membrane layer)
  • Walkways
  • Deck and balcony areas
  • Exposed roof surfaces for maintenance and access areas
  • General horizontal surfaces exposed to weather


Gripset LS membrane must be applied onto primed surfaces using the appropriate primer based on the surface type:

  • Xpress Primer H20 Plus - For concrete rooftop applications, green/damp concrete, screeds, and mineral surfaces containing residual moisture
  • Gripset GP primer for general porous vertical and horizontal building surfaces. Apply the primer using a brush or roller to the total surface area at a minimum coverage of 1 litre per 6m². Allow drying for 30 minutes or until the wet film dries to a clear transparent coating.
  • Gripset OP primer for non-porous, smooth, and dense surfaces. Apply the primer using a brush or roller to the total surface area at a minimum coverage of 1 litre per 12m². Allow drying for 1 hour.
  • Gripset 11Y slurry for asphalt/bitumen surfaces and existing coatings. Mix Gripset 11Y in equal volumes with Portland cement and fine wash sand to form a homogeneous slurry. Brush apply the slurry to the substrate at a coverage of 1 litre per 3m². Apply the membrane over the primer slurry while the primer is in a damp/wet state, i.e., "wet on wet" application. Check suitability over existing coatings with Gripset Technical Services before commencing.
  • Gripset P10 or E60 primer for surfaces with residual moisture or subject to rising damp. Refer to individual data sheets for specific coverage details. Allow the respective primer to dry for a minimum of 24 hours before applying the membrane.

Note: Please refer to the data sheets for the above primers before using.

Storage Conditions

  • Best stored at room temperature
  • Avoid cold freezing conditions and off concrete floors
