Waterproof Bathroom Liquid Membrane :  

 

Duromastic P15 membrane is a modified acrylic urethane membrane. This membrane has been formulated to create a tenacious bond to most surfaces.  It is a tough flexible waterproof membrane with a high film strength, and exceptional elongation and elasticity, that will expand and contract under normal substrate movement. It is supplied as a thixotropic liquid, which is easily applied to both vertical and horizontal surfaces. The formulation is fully optimised to ensure quick tack free time, fast cure, high solids, excellent chemical resistance. It fully complies with the test requirements of AS:4858-2004 and AS:3740:2004 "Waterproofing of Wet Areas within residential buildings"

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 mastic PU or neutral-cure silicone. Install leak control flanges to all pipe penetrations.

 

PRIMING

 

Prime fibre cement board, sound concrete and block work with Duromastic ARW

internally. For external applications prime with Duromastic AR Sealer applied at approximately 6m2/litre. Damp areas and areas subject to rising damp should be sealed with Duromastic 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 which must be fully wetted out with out wrinkles or bubbles. Alternatively, Wrimco Flashing Tape may be used   
 

APPLICATION

 

To the primed surfaces, apply Duromastic P15 by brush or roller in at least two or more coats to achieve a minimum dry film thickness of 1.0mm. 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 according to the manufacturer's directions before membrane, is applied. Do not apply above 30 C or below 10 C ambient.
 

CLEAN UP

 

Duromastic P15 may be cleaned from equipment with water when still wet.
 

FLOOD TEST & TILING

 

A flood test may be carried out after 72 hours of drying, @25 C, 50% R.H. Water shall cover to a depth of 25mm for approximately 2 hours. Duro P15 may be tiled over after 3-4 days @ 25 C & 50% R.H., using a quality cement based tile adhesive installed as per AS 3958.1.

 

STORAGE

 

Stored in unopened original containers, Duromastic P15 has a shelf life of 12 months. Store between 5 C and 30 C and away from direct sunlight. Opened pails may form a skin on the surface but this can be removed and the remaining product used.

Avoid prolonged contact with skin. Material Safety Data Sheets are available

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.

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.
