Sealoflex Enviroflex™ Liquid Applied Waterproof Coating - Icopal

Enviroflex™ Liquid Waterproof Coating

Enviroflex™ Liquid Waterproof System is suitable for use as an exposed membrane in both new and refurbishment projects, particularly where traditional methods of waterproofing may prove difficult.

It is intended for use where limited foot traffic is anticipated, but may also be used in conjunction with the Enviroflex™ anti-skid walkway system on projects involving more heavily trafficked areas, such as access routes, for example.

Enviroflex™ Liquid Waterproof Coating is a single component polyurethane based, moisture curing coating applied in multiple layers in conjunction with a polyester reinforcing fleece. The coating is vapour permeable, and suitable for use on both new and remedial projects. Enviroflex™ Liquid Waterproof Coating is available in a mid-grey colour or white, and is supplied in 4 litre and 15 litre tins.

Surface Preparation

Ensure the substrate is sound, clean, dry and free of frost, dust and debris, and any material which would hinder adhesion. Residual moisture in concrete substrates must not exceed 5% in the upper 2 cm.

Application Conditions

Apply only when atmospheric and substrate temperatures are greater than 5 °C. The surface of the substrate should be clean and dry and must be 3 °C above the dew point. If the surface is below or at dew point temperature then moisture can form at the surface and affect coating adhesion and curing.

For optimal ease of application, the Enviroflex™ Liquid Coating should be above 12 °C.

Personal Protective Equipment (PPE) should be worn.

Coverage Rates

The Enviroflex™ System is applied ‘wet-on-wet’ allowing full membrane application in a single process.

The total application rate of Enviroflex™ Liquid Waterproof Coating depends on the porosity and texture of substrate and the system selected - see design guide.

Application Method

Prior to the application of the Enviroflex™ Liquid Waterproof Coating, prime the substrate with an appropriate Enviroflex™ Acrylic Primer or Enviroflex™ EP1 Primer, and allow to cure.

Coating Preparation: Once opened stir Enviroflex™ Liquid Waterproof Coating thoroughly. Be careful not to over stir the coating as over stirring can introduce air to the coating. Allow to settle for 5 minutes if air bubbles are visible within the coating. Where the consistency of the coating appears thick, place the container into a larger bucket of hot water - raising the temperature of the coating will improve viscosity.

Application: In accordance with the combined system coverage rates above, apply approximately 1/3rd of the Enviroflex™ Liquid Waterproof Coating above the primed substrate as the base layer using a brush or roller.

Immediately apply the Sealoflex Reinforcing Fabric into the base layer and roll the surface with a perlon roller, eliminating potential air bubbles. Overlaps in the reinforcing fabric should be a minimum 75mm.

Apply immediately the remaining 2/3rd of Enviroflex™ Liquid Waterproof Coating above the reinforcing fabric as the top layer.

Roll out evenly until complete saturation is achieved. Ensure the overlap areas (above and below the overlapping fabric) are fully saturated to maintain continuity of the waterproofing system.
