Wrimco Waterproofing Co -

DUROMASTIC ACS is a liquid applied acrylic membrane which, when reinforced and fully cured, forms a flexible waterproof lining for showers and other wet areas as described in Australian Standard AS 3740-2004 "Waterproofing of wet areas within residential buildings". and AS4858:2004 "Wet Area Membranes". DUROMASTIC ACS forms a waterproof lining to most building materials including reinforced concrete, cement render, water resistant plasterboard and fibre reinforced cement sheet flooring etc. The surface must be firmly fixed to manufacturers directions, free of protrusions, dirt, oil and other contaminants and surface must be dry.

CLEANUP

Clean up with fresh water before dry.

APPLICATION

NOTE: Floor wastes in concrete should be cut to floor level with no up stands. For sheet flooring, leak control flanges should be recessed, flush with the substrate. All PVC fittings, shall be etch primed.

Step 1:

Remove all dirt, dust, plaster droppings, protrusions, oil and contaminants. Fillscrew holes with Neutral Cure Silicone. All sheet joints should be filled with Neutral Cure Silicone.

Step 2:

To joints in sheet flooring, wall/floor junctions wall/wall junctions and all hob junctions, apply 12mm neutral-cure silicone* sealant as a bond breaker/slip joint. Vertical joints should extend 75-100mm from floor and to 1.8m high in showers. Apply sealant around floor penetrations, tap flanges and other protrusions. For all floor joints up to 5mm wide install bond breaker tape greater than 12mm or Neutral Cure Silicone.

Step 3:

Priming: Concrete Render, CFC, timber and Plaster board. Prime internal substrates with DUROTECH ARW Sealer. Prime external substrates with DUROTECH AR Sealer, DUROMIX WBE (DUROMASTIC WBE), for damp surfaces at the rate of 3 - 4 m2/Ltr.

Step 4:

To the prepared surface apply a heavy coat of DURO MASTIC ACS by brush or roller at approx 0.5-1 litre/m2. Immediately lay the matting into the wet surface, then apply another coat and work in carefully by brush or roller to saturate the matting. Completely saturate the matting ensuring no misses. Excessive application of DURO MASTIC ACS will greatly reduce drying time. Apply sufficient coats for overall DFT of 1mm.

Reinforcement:

Use 225 gsm fiberglass and/or equivalent synthetic reinforcement as follows. Use reinforcement to total floor area and bandage floor joints, wall/floor junction, wall/wall junctions and shower hobs. Ensure the membrane is dressed down into the floor waste or well sealed around the leak control flange and also ensure membrane is turned up to penetrations.

Step 5:

When dry apply one or more coats to give a fully waterproof lining. Apply one heavy coat to the walls above shower tray to 1.8m high. When dry check for pin holes or misses and rectify if necessary.

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 ACS 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.

PRECAUTIONS

Do not apply above 32C or below 8 OC. Wash equipment with water before dry. Do not fix tiles until fully dry, normally 3-4 days. Areas subject to rising damp should be first sealed with an epoxy coating, i.e.

DUROMASTIC WBE. Protect membrane against damage before and during tiling. Tile over external compressed fibro within 4 weeks. When tiling over external membrane surfaces ensure full allowance is made for expansion and contraction which may damage the membrane. Do not expose to solvents.

Not hazardous in normal industrial use.

4. FIRST AID MEASURES

Eyes:

Immediately flush with water for 15 minutes. Get medical advice if irritation develops or persists.

Skin:

Take off all contaminated clothing. Wash contaminated area with soapy warm water. Get medical advice if irritation develops or persists. Wash contaminated clothing and clean shoes before reuse.

Inhalation:

Remove to fresh air. If not breathing, give artificial respiration, preferable mouth to mouth. If breathing is laboured, give oxygen and consult a physician immediately.

Ingestion:

Consult a physician immediately. If vomiting occurs, aspiration into the lungs may cause lung damage. Never give anything by mouth to an unconscious person.

Respiratory Protection:

If vapours and mists occur, a respiratory protection program meeting Australian Standards AS-1716 and AS-1715 requirements must be followed whenever workplace conditions warrant a respirator's use. None required if airborne concentrations are maintained below the exposure limit listed in "Exposure Limit Information"

Eye Protection

Use chemical splash goggles (Australian Standard AS-1337) or approved equivalent. Eye protection worn must be compatible with respiratory protection system employed. An eye wash station and safety shower should be available in the work area.

Hand Protection

Impermeable gloves as necessary to prevent skin contact. E.g. nitrile or neoprene gloves.

Protective Clothing

Clothing made of the following material has excellent resistance : Tyvec, butyl nitrile rubber or neoprene.
