Licensed ApplicatorsApplication begins with the licensed applicator inspecting the substrate and area to be waterproofed.

The applicator will communicate any problems with the installation of the wall , floor or deck substrates back to the installer or builder, who must remedy the situation prior to the installation of “Flexi-Seal”. At this stage- the first stage “substrate installation” is signed off.

The second stage comprises of the preparation and waterproofing process.

The “Flexi-Seal” system can be applied to most substrates, but generally, concrete, cement board, gib board, plywood and particle board are the common ones.

Step 1 requires the substrate to be clean, dry and free of any dust and contaminants. Substrates, which are contaminated with moss lichen and mould, will first require treatment with “Orgo-Clean”, organic moss and lichen control, followed by washing down or waterblasting.

Step 2 requires holes to be filled, particularly on plywood decks and particleboard floors. “Flexi-Seal Nail ‘n Screw” Patch is used for this process. Also at this stage galvanised heads on clouts etc are spot primed with “Flexi-Seal Mega Prime”. This is a two part epoxy primer.

Step 3 requires the bondbreaker mechanism to be put in place. Floor/wall and wall/wall junctions are filled with a siliconised compound. Larger gaps may require a foam-backing rod to be installed first. These junctions are then reinforce taped with “Flexi-Seal Reinforcing Tape”, as are floor and wall joints. Cracks in concrete floors are also reinforced.

Step 4 involves the application of a single saturation coat of Flexi-Seal Sealer / Primer on concrete, gib and cement board. This is applied to the entire area, paying attention to even coverage both to walls and floors. This is a milky white penetrative solution that will soak in and further stabilise the substrate, leaving either an invisible or slightly low sheen clear coating on the surface. “Flexi-Seal Mega Prime” is used on plywood and particle board surfaces.

After approximately 1 hour cure, the waterproofing process can begin.

This is a two coat process, and each coat is applied at a rate of approximately 1 litre per square metre.

The first coat cures to a very dark grey colour. The two part membrane is mixed proportionally by weight and then applied to all surfaces with care being taken to prevent unnecessary buildup at joins and junctions.

After approximate 45 – 60 minutes of drying/curing, the second coat can be applied.

The second coat is a lighter grey colour. This is a different colour to the first coat to ensure 100% proof of coverage. Once again attention is paid to unnecessary buildups and any pinholing which may have appeared in the first coat.

Curing of the finally installed membrane is important. The final system must be fully cured prior to the installation of tiles or other floor or wall coverings over the top. Allow 24 hours minimum. Longer cure times may be experienced in colder temperatures or conditions with poor air circulation. Once cured and a check of the membrane is made, the licensed applicator will sign off stage two.

The third stage involves the applicator confirming the “Flexi-Seal Licensed Waterproofing System” is now ready for tile or floor/wall coverings. This is confirmed by a signature to the guarantee, and evidence of the “Flexi-Seal” approval and guarantee stencil on the site of installation.

NB: For walls and floors with hydrostatic water problems, “Flexi-Seal Positive Pressure Coat” is used, prior to application of “Flexi-Seal 2 Part Liquid Membrane”.
