Watco Safety Grip Flex

Surface preparation

Bare Concrete – remove surface laitance, dust and any light dirt or grease deposits using Watco Etch & Clean. Watco Etch & Clean also etches smooth, bare concrete surfaces to provide a key. Flush with clean water and allow the surface to dry. For the removal of heavier deposits of oil and grease we recommend Watco Concroff, again, flush with clean water and allow the surface to dry.

New Concrete – as a guide, new concrete should be left for 8 weeks to dry. The surface should then be prepared using Watco Etch & Clean, thoroughly rinsed and left to dry.

Priming – is not usually required, but for very porous high suction surfaces, such as sand and cement screed, use Watco 4 Hour Epoxy Primer. Concrete should be sufficiently porous to allow the paint to penetrate, so very smooth or power floated concrete is unsuitable unless first primed with Watco Powerfloat Primer.

Painted Surfaces – Diamond grind the surface prior to application to achieve a consistently rough profile, and ensure all weakly bonded material is removed. Glossy or inadequately prepared surfaces may cause adhesion issues, so a thorough inspection is recommended to ensure no areas are missed, a bristle blaster can be used in any hard-to-reach areas. Thoroughly sweep the area following grinding; any loose material or dust can compromise adhesion. Bio-D can be used to remove any grease and oil from the surface following the grinding process, however, surfaces washed with Watco Bio D must be then thoroughly rinsed with water and allowed to dry fully, prior to coating.

Asphalt – new asphalt must be sound and at least 3 months old. If any residual oils remain, the surface should be washed using Watco Concroff. Painted asphalt should be cleaned with Watco Bio D (Concroff can soften paint), and a trial area is advisable to test compatibility with previous coatings.

Metal – remove any rust and flaking material by disc grinding or wire brushing. Apply the coating immediately after preparation to the clean metal surface. Grease or oil can be removed using Watco Bio D. Allow the metal to dry before coating.

Galvanised Metal – Watco Galvaprime must be used to prepare galvanised metal.

Non-ferrous Metals – for advice, please contact our Technical Department.

Mixing and application

• Individually stir the resin and curing agent using a Watco Mixing Blade, or a wooden batten at least 25mm wide is ideal
• Pour the mixed components into the larger outer tin and stir thoroughly until uniform in colour
• Pour the mixed resin and curing agent into a shallow roller tray
• Apply the mixed resin and curing agent by Medium Pile Roller (not foam) to a measured area of 5m². A paint brush may be used for cutting in around the edges
• Immediately sprinkle the anti slip aggregate, uniformly, onto the wet coat to obtain the desired surface finish (total or light coverage)
• Using the same roller that was used to apply the mixed resin and curing agent, roll over the sprinkled aggregate to bed in. Do not re-charge the roller with mixed resin and curing agent unless very heavy quantities of grit have been applied, since this will result in a loss of slip resistance
• Avoid washing the surface for 7 days after application In exceptional temperature conditions advice should be obtained from Watco’s Technical Department

Maintenance

Remove dirt with a medium stiff broom or light scrubbing machine using detergents if necessary - Watco Bio D is ideal.
