Overview

LeesonGrip 2-1 (D3149/20) is a two-component solvent-free urethane system which when used with, for example, 2-4mm Bauxite or similar aggregate to give a High Friction Anti-Skid Surface, meets the requirements of the BBA system: approval number is 01/H049.
Urethanes cure rapidly especially at low temperatures allowing earlier opening of sites to traffic. This is a significant advantage when application is made at night when temperatures are low. Typical surfaces include roads, pedestrian crossings, cycle paths, bridges, walkways, stairs, car park decks, ramps, flooring, airport runways, etc.

Applications

  • Type 1 Roads
  • Industrial Floors
  • Carparks
  • Ramps
  • Airport Runways
  • Cycle Paths
  • Walkways
  • Drives

How to use

  • Surface Preparation – Bituminous Surfaces

    The road surface should have a texture depth of between 0.5mm and 2.0 mm as determined by the sand patch test. All imperfections in the road surface should be repaired prior to laying the product.
    The surface to be treated must be clean, free from frost, ice, and road salt. The surface should also be sound, dry, and free from dust and any loose material. Any visible oil should be removed with a detergent solution, flushed with water and the surface allowed to dry.
    We also have available a cementitious scratch coat system (D5126), for filling porous asphalt to reduce topcoat consumption.

  • Surface Preparation - Concrete and timber

    Concrete is to be hot compressed air blasted then primed with primer PU3922 and this allowed to cure for a minimum of 2 hours and maximum of 12 hours before applying the finish coating. On timber, the surface should be primed with primer PU3922 and conditioned as above.

  • Surface Preperation - Steel

    It is to be shot blasted to SA2.½ and primed and allowed to cure 1-2 hours minimum, maximum 12 hours before finish coating.

  • Mixing and Application

    Add 1 part by weight of Leesongrip D3149 Part B (curing agent) to 2.15 part by weight of Leesongrip D3149/20 Part A (resin) and mix until a mass of uniform colour is obtained.
    The surface is then coated with the blend within 10 minutes (@ 19°C) at a minimum coverage rate of 1.5 kg per m2 dependant on surface porosity and then allowed to self-level to give total coverage. The non-slip aggregate (moisture content less than 0.4%) is then scattered over the resin within 5 minutes (@ 19°C) excess aggregate can be removed after 2 hours. The site can be reopened to traffic after 4 hours depending on ambient temperature or until the binder is hard to the touch.
    DO NOT USE IN TEMPERATURES BELOW 5°C.

FAQs

What is the estimated coverage rate of D3149/20?

Coverage is dependent on surface porosity and installer preference. Typically, between 1-7-2kg/ m². Minimum coverage is 1.5kg/m²

How soon after installed can the surface be reopened to traffic?

The site can be reopened to traffic after 4 hours depending on ambient temperature or until the binder is hard to the touch.

What are the friction properties of D3149/20?

D3149/20 has an initial skid resistance value (SRV) of >100. After 100,000 wheel passes it achieves an SRV of approximately 85.
