SS Membrane

Description:

 

Nutech Membrane is a high quality emulsion coating designed as a decorative, flexural, elastomeric coating for sealing and waterproofing roofs, walls, and wet areas. NT Membrane is a hard wearing and durable coating suitable for asphalt, concrete, masonry, or other applicable surfaces. For traffic areas it is recommended to use a reinforcing fabric in the first top coat. The Membrane can be colour tinted in a range of colours. The product does not require oversealing or topcoating. A penetrative masonry (NuPrime) or metal primer (AC Metal Primer) may be required prior to top coating with the membrane.

  Application;

All substrates should be clean, free of dirt, loose material, grease, efflorescent salts, mould, fungi, stains, rust, form oil, silicon, or any other foreign material prior to coating with membrane.

Surfaces must be free of hydrostatic pressure or continual wetting.

A minimum of two coats of Membrane are essential for permanent results. Lay the membrane on rather than brushing it out. Two different colours may be used to facilitate easy application. Suitable application techniques include airless spray, roller, or brushing. Apply coats at right angles to prior coat.

To obtain a decorative or textured finish it is recommended to follow the appropriate application rate listed below:

Primer 1 coat @ 4 m² per litre 200 microns D.F.T.
Smooth 2 coats @ 3 m² per litre 200 microns D.F.T.
Stipple 2 coats @ 2 m² per litre 350 microns D.F.T.
Hi-Build 3 coats @ 1 m² per litre 550 microns D.F.T.

  Surface Preparation :

Iron, Steel, Galvanised, and Zincalume Surfaces:
Remove excessive oil or grease. Prime with 1 coat of AC Metal Primer

Rusty Steel or Iron
Remove all loose rust and paint. Apply a Rust Converter before priming with 1 coat of AC Metal Primer

Aluminium or Copper
Apply 1 coat of Etch Primer to a clean dry surface prior to coating with Membrane.

Sound Previously Painted or Primed Surfaces
Wash old paintwork to clean surface. Sand or wire brush existing coating (especially full gloss finishes) to achieve a sound adhesible surface.

Wood
Apply a suitable timber primer, then treat as a painted surface.

Powdery Paintwork
Remove all loose material if possible. Apply 1 coat of NuPrime @ 4 m² per litre to achieve a sound surface.

Absorbent Masonry
Apply one saturation coat of NuPrime @ 3m² per litre.

Concrete, Brickwork, and Cement
Remove all loose material and repair any defects. Smooth trowelled surfaces should be acid etched. Rinse thoroughly with water before applying one saturation coat of NuPrime @ 3m² per litre.

Crumbling Walls
Remove loose material before repairing, then treat as masonry or brick surface.

Movement Points
Where bridging structural joints or cracks, a layer of chopped strand fibreglass matting, or polyester fabric reinforcing must be embedded into the top coat of Membrane and overcoated with a minimum two coats of membrane. Expansion joints should be filed or sealed prior to Membrane application.

Mouldy Surfaces
Scrub or scrape clean all surfaces and apply a biocidal wash. Repair damaged areas, allowing all areas to dry before applying the Membrane coat.

Asphalt or Bitumen
Apply 1 coat of Membrane to a sound, firm, and non-tacky surface.
