Application

Surface preparation:
All surfaces must be structurally sound, stable, dry, clean, and free of dust, loose, flaking, friable material and free from oils, grease, form release agents, curing compounds, and any other surface contamination that may hinder adhesion. Ensure that surfaces are free of protrusions to achieve a continuous, even film build. Removal of sharp edges and ridges, chamfer external corners 12mm. Non-structural cracks, holes, and deformities are to be rectified. Substrate must be free from surface water and continual dampness. Concrete must be allowed to cure for at least 28 days.

Screed and render:
A 3:1 ratio sand and cement screed, or Gripset C-Bed engineered screed is recommended if falls need to be created prior to membrane application. Sand cement screeds and cement render must be allowed to cure for at least 4 days prior to the application of primers. Failure to do so may result in poor adhesion and subsequent delamination.

Priming:
The use of a primer is always recommended, particularly on porous and warm surfaces. For internal applications, Everflex WBP is typically sufficient, while for external applications like Roof Terraces and Balconies, Everflex VBS is advised. Refer to the primer Technical Data Sheet (TDS) to ensure you have the appropriate primer for your application and apply it in accordance with the primer’s TDS. Once the primer is touch-dry, apply Everflex WPM within 24 hours; times vary depending on atmospheric conditions. Metal surfaces: a metal etch with either VBS or OP primer. For other non-porous surfaces, OP primer is normally sufficient.

Everflex WPM Installation:
Please note that installation of the WPM waterproof system must be strictly in accordance with the requirements as detailed in the National Construction Code.

Before use, mix Everflex WPM thoroughly. Using a brush and or roller, apply the first coat of product to achieve an even and consistent coat of approximately 0.75mm wet film thickness. Once the first coat has dried, apply a second coat at a right angle to the first coat at 0.75mm wet film thickness. Verify wet film thickness with a film thickness gauge. Everflex WPM must be applied with a minimum of two coats, achieving a minimum dry film thickness (DFT) of 1mm. The average recoat time is 2-4 hours after being dry to the touch, and within 24 hours, at 25˚C and 50% humidity. These times vary depending on atmospheric conditions. If more than 2 coats are required to achieve the minimum DFT, apply additional coats at right angles to the previous until the correct DFT is achieved.

Waste Outlets, Penetrations and Angles

Waste Outlets:
Floor wastes and puddle flanges should be rebated into the floor to allow water to readily drain. Fill all gaps and perimeters with Adheseal PU or Hi-Flex MS sealant.

Waterstops:
Where required by the NCC, including door barriers, balcony edge trims or shower waterstops, they should be sealed and secured with Adheseal PU or Hi-Flex MS sealant.

Gaps, Joints and Transitions:
Apply a fillet forming a cove, with Adheseal PU, Hi-Flex MS sealant or suitable bond breaker to internal corners and over sheet joints, bond breaker to be 12mm for wet areas, 38mm for external above-ground gaps, joints and internal corners. For additional protection, apply polyester reinforcing fabric to the corners and joints saturated into the first coat of membrane. For dynamic cracks/expansion joints and control joints, the use of Adheseal Elastoproof is recommended. For any further guidance, please contact the Adheseal Technical Department.

Limitations

• Do not apply membrane when temperatures are below 10 °C or above 35 °C.
• Limited U.V. resistance (not designed for long term U.V exposure and must be tiled or topped).
• Do not apply on damp, wet or contaminated substrates, if it is raining or if rain is imminent.
• Not suitable as an exposed membrane
• Not suitable for areas subject to negative hydrostatic pressure or rising damp.
• Foot traffic

Acceptable Substrates

• Concrete.
• Sand cement screed or Engineered screeds.
• Masonry/render.
• Cement sheeting/underlay / external weatherboard / blue board
• Pre-cast concrete, once the release agent has been removed/dissipated.
• Wet area plasterboard / Villaboard
• Timber flooring, including structural plywood Type A (PAA JAS-ANZ)
• Brickwork, Hebel (aggregate block)
