CLEANUP

DURO MASTIC TOUGHSET may be cleaned from equipment with water when still wet.

INSTALLATION

SURFACE PREPARATION

Ensure linings are firmly fixed to manufacturer's directions. Surface must be free of dirt, dust, loose particles, oil, contaminants and curing compounds etc. Concrete must be a minimum strength of 20mpa and have cured a minimum of 28 days. Surface must be dry. Fill all screw holes, cracks and voids with neutral-cure silicone. Install leak control flanges to all pipe penetrations.

PRIMING

Prime fibre cement board, sound concrete and block work with Durotech ARW Primer internally. For external applications prime with Durotech AR Sealer applied at approx. 6m2/litre. Damp areas and areas subject to rising damp should be sealed with DUROMIX WBE . Allow primer to dry prior to membrane application . All PVC fittings to be etch primed.

DETAILING

Apply a 12mm fillet of neutral cure silicone between all horizontal and vertical junctions such as floor to wall, wall to wall, all hob junctions and any joints in the substrate. Apply neutral cure silicone around penetrations and outlets. Where angles are installed, such as across bathroom doorways or under shower screens (hobless showers), the angle must be firmly adhered. Joints, corners & other details shall be reinforced with polyester bandage or Duro Flashing Tape which must be fully wetted out with out wrinkles or bubbles.

APPLICATION

To the primed surfaces, apply DURO MASTIC TOUGHSET by brush or roller in at least two or more coats to achieve a minimum dry film thickness of 1.2mm. Do not apply in 1 coat. Turn membrane up to walls, penetrations and down into drainage outlets. When dry, check for pinholes and recoat if necessary. If membrane becomes dirty or damaged between coats, clean with water and recoat . All sheet flooring must be fixed to the manufacturers directions before membrane is applied. Do not apply above 30 o C or below 10 o C ambient.

FLOOD TEST & TILING

A flood test may be carried out after 72 hours of drying, @25 o C, 50% R.H. Water shall cover to a depth of 25mm for approximately 2 hours. DURO MASTIC TOUGHSET may be tiled over after 3-4 days @25 o C, 50% R.H., using a quality cement based tile adhesive installed as per AS 3958.1.

STORAGE

Stored in unopened original containers @ 20 o C, DURO MASTIC TOUGHSET has a shelf life of 12 months.
