(Pre Mixed Flexible Fibre Reinforced)

WATERPROOF MEMBRANE
Paint or trowel on compound for use before tiling, is a tough, flexible and seamless part liquid applied membrane. It is suitable for waterproofing shower recesses, internal wet areas, balconies and planter boxes.


SPECIFICATION CLAUSE
The waterproofing membrane shall be Morgan Pre Mixed Flexible Fibre Reinforced Waterproof Membrane a seamless one pack acrylic modified membrane formulated to provide a tough, long lasting water barrier under tiling systems.

WATERPROOF MEMBRANE is a liquid acrylic which is reinforced with mesh fibres and when fully cured forms a waterproof lining for showers and other wet areas as described in Australian Standards AS 3740 1994 (Waterproofing of wet areas within residential buildings). Waterproof Membrane forms a waterproof lining to most materials used for building construction including reinforced cement sheets (e.g. villaboard, versalux), some particle board flooring (MDF refer to Morgan Adhesives) and plywood etc.

BACKGROUND PREPARATION
The surface must be dry and firmly fixed according to manufacturers instructions, free of protrusions and any contaminants. A bead of clear silicone should be applied to all
joints and worked in.

Priming: The walls and floors to be treated must be primed. Apply the primer with paint roller or brush. Primer (Plastinex, see instructions on label) will be touch dry in 20 minutes depending on weather conditions. Coverage of primer is approx. 10sq metres per litre.

Concrete: Allow to cure for at least 7 days for every 25mm thickness.

Cement Render: Allow to cure for at least 14 days.
Fibre Cement and Plasterboard: Should be suitable for wet conditions and securely fastened to the framework according to the manufacturers instructions.

MEMBRANE DRYING TIMES
Recoat Time: 2 hours between first and second coats. Alternatively, if a reinforcing mesh is used between coats then the second coat may be applied while the first coat is still wet.
(Apply in opposite direction to the first coat).

Dry Through: The slowest drying times are those where the membrane has been applied over silicone eg: wall and floor joints. The membrane cannot be tiled over until these critical areas are completely dry. The membrane is totally dry in 48 hours (25oC/50%RH) but can take up 72 hours (10oC/50%).

Fully Cured: The shower should not be ready for use until the membrane has reached its full strength. The membrane is fully cured 7 days after it has been applied. Drying times will vary depending on climatic conditions and surface porosity.

COVERAGE
Approx. 1.5kg per square metre at 1 mm dry film thickness.

CLEANING
Clean equipment with clean water while material is still wet.

CERAMIC TILING OVER
Sheeted Walls: Use One Pack Mastic, Morflex or Promastic.
Rendered Walls: Use Powegrip Grey/White, Morflex.
Cement Floors: Use Morflex, Tilefast Superior, Morflex Plus.
Sheeted Floors: Use Powerflex Grey/White, Resinflex 1 Pack.

GROUTING
Allow adhesive to dry 24 hours. Use Morgans Sanded Coloured Grout with Grout Add or Superior Grout.

SHELFLIFE
12 months if stored in original packaging in a cool dry place between 10oC and 25oC.

PRECAUTIONS
Do not use the product in the following situations:
• areas subject to negative hydrostatic pressure or rising damp.
• where the substrate is not dry or rain is imminent.
• where the membrane will be exposed and subject to regular foot traffic.
• on glazed, glass or other totally impervious surfaces (eg. areas pretreated with water repellents)
• where the surface temperature is below 1OoC or higher than 35oC.

All floors must have proper falls either built into the substrate or achieved with sand cement screed.

Waterproof Membrane is non-hazardous. However in the case of eye contamination, rinse with clean water and seek medical advice.

Protect membrane from washout rain for 24 hours.

APPLICATION FOR SHEETED WALLS & FLOORS

  1. Ensure wall and floor sheets are installed as per sheet manufacturers instructions, with a 5-6mm gap between the wall sheet and the floor.
  2. Ensure sheets are securely fixed to the wall at the bottom edge and sheet joints are treated with silicone or bond breaker.
  3. Apply silicone to all horizontal and vertical corners.
  4. Seal the perimeters of taps and waste outlets with silicone.
  5. Treat all nail and screw holes with silicone.
  6. For timber flooring avoid sheet joints in shower recess floor.
  7. Ensure outlet pipes are fixed securely and that the waste drainage flanges are recessed into the floor.
  8. Ensure brick/concrete hobs are used (do not use timber) and that the top of the hob does not slope outwards.
  9. Ensure that fails to the waste are a minimum 1:80 (i.e. 25mm in 2 metres) before waterproofing.
  10. Apply the membrane 1800mm up the walls or to the height of the shower rose within the shower recess. (Two coats in opposite directions).
  11. Apply the membrane to the entire shower recess floor and down into the waste or puddle flange. (Two coats in opposite directions).
  12. Apply the membrane over the hob and at least 75mm beyond outside edges of the hob (ideally apply membrane to entire wet area floor)
  13. Install the shower screen to the outside edge of the hob.
  14. (Optional) 150mm reinforcing mesh can be used in all vertical and horizontal joins for added strength.

A DRY FILM THICKNESS OF 1.5 - 3MM WILL NEED TO BE ACHIEVED.
NOTE: Before shower screen is fitted notify installer that a waterproof membrane has been applied and act accordingly.


APPLICATION TO CONCRETE/BRICK RENDERED WALLS & FLOORS

  1. Apply silicone to all horizontal and vertical corners.

  4. Ensure brick/concrete hobs are used (do not use timber) and that the top of the hob does not slope outwards.
  5. Ensure that falls to the waste are a minimum 1:80 (i.e. 25mm in 2 metres) before waterproofing.
  6. Apply a bead of silicone to the junction of the hob or angle and walls.
  7. Apply the membrane to the entire shower recess floor and down into the waste or puddle flange. (Two coats in opposite directions).
  8. Apply the membrane over the hob and at least 75mm beyond outside edges of the hob (ideally apply membrane to entire wet area floor) (Two coats in opposite directions).
