APPLY 1st COAT Apply a thick coat (1.5mm wet) of HDYRATHANE 75mm either side of the wall junctions and around tap outlets. Coat the remainder of the floor and wall.Take care to seal around the tap and faucet outlets. Recoat time: Two hours (depending on weather conditions). Application Temperature: Apply coating in ambient temperatures between 10°–30°C. APPLY a 2nd COAT Apply a 2nd coat of HYDRATHANE to the area to be tiled – recoat time is 2 hours. Apply the second coat of HYDRATHANE at 90° to all of the previous coat applying a thick coat (1.5mm wet) to ensure final dry thickness of 1.5mm. Clean up the uncured coating with clean water. THICKNESS Check the wet film thickness at 0.5 metre intervals and also at 0.5 metres along the bond breaking tape, with a wet film thickness gauge. ADHERE TILES Allow the membrane to cure for 72 hours before fixing tiles with KEMGRIP FLOOR AND WALL mixed with ELASTACRETE or KEMFLEX 2:1, GRIPFLEX, MONOFLEX.Tiles must be laid so that adequate fall is towards the floor waste.

DESCRIPTIONA waterproofing kit for enclosed shower alcoves. Suitable for use on concrete, compressed cement sheetingand walls constructed of brick, block, render, cement sheeting and waterproof gypsum building board.

COVERAGE (Approximate)2 litre/m2 at 1.5mm dry film thickness.

CONTENTS OF KIT• 1 litre PRIMER AND GROUT ADDITIVE • 4 litre HYDRATHANE• 140mm REOMAT • 50mm Bond breaking tape • Brush

APPLICATIONSURFACE PREPARATIONWaterproofing must be in accordance with AS3740Surfaces to be waterproofed must be sound and free of dirt, dust, grease and other contaminants and allowed to drybefore priming. The waste hole in compressed cement flooring must be cut no more than 5mm larger than the wasteexternal diameter. Recess drainage flange. New concrete must have cured for 28 days.

PRIMINGApply PRIMER & GROUT ADDITIVE with a brush to the prepared dry surface. When the surface becomes dry (afterapproximately 15-20 minutes) apply the HYDRATHANE – wash up with clean water.

BOND BREAKERPlace 50mm Bond Breaker at the floor/hob and wall/wall junctions and joins in sheeting equally to both surfaces. Thiswill allow for greater movement accommodation, should it occur.

JOINTS/CRACKS IN BUILDING SURFACESAt junctions in building surfaces and over cracks place a bond breaker, tape or neutral cure silicone bead (as per ASNZ4858/2004) and reinforce the first wet coat with 140mm REOMAT (to accommodate extremes in movement). Placethe bond breaker/silicon bead and REOMAT centrally over the joint or crack.

APPLY 1st COATApply a thick coat (1.5mm wet) of HDYRATHANE 75mm either side of the wall junctions and around tap outlets.Coat the remainder of the floor and wall.Take care to seal around the tap and faucet outlets. Recoat time: Twohours (depending on weather conditions). Application Temperature: Apply coating in ambient temperaturesbetween 10°–30°C.

APPLY a 2nd COATApply a 2nd coat of HYDRATHANE to the area to be tiled – recoat time is 2 hours. Apply the second coat ofHYDRATHANE at 90° to all of the previous coat applying a thick coat (1.5mm wet) to ensure final dry thickness of1.5mm. Clean up the uncured coating with clean water.

THICKNESSCheck the wet film thickness at 0.5 metre intervals and also at 0.5 metres along the bond breakingtape, with a wet film thickness gauge.

ADHERE TILESAllow the membrane to cure for 72 hours before fixing tiles with KEMGRIP FLOOR AND WALL mixed withELASTACRETE or KEMFLEX 2:1, GRIPFLEX, MONOFLEX.Tiles must be laid so that adequate fall is towards the floorwaste. A cement screed can be used to achieve this.

GROUTINGAllow adhesive to cure 24 hours before grouting with KEMGROUT FLEXIBLE. COLOUR SEAL is applied to thesurface at the junction of wall/wall, wall/floor and hob/floor, hob/wall in place of the grout.

PRECAUTIONAllow the HYDRATHANE to cure for 28 days before putting into use. It is advisable to flood test the shower aftercuring (approx. 72 hours 20°C 50 RH).This should be done before tiling commences.
