Unitex® Uni-Dry Cote® Harbour Fine is trowel-applied (sponge finished) and suitable for a one-coat or two-coat application on all suitable masonry surfaces, eg Brick or Block etc, both inside and out, and is recommended to aid in the protection of masonry walls from the damaging effect of surface ingress of moisture. If the surface is in good order only a skim coat is required.

Unitex® Uni-Dry Cote® Harbour Fine is a cement based polymer modified, High Performance Water Resistant and adhesion promoted masonry render system. Unitex Uni-Dry Cote® Harbour Fine is applied direct to sound and prepared masonry surfaces, either mechanically (sprayed) or by Trowel and rubbed up to a true and even surface with a float. This product is workable at thicknesses up to approximately 10mm.

Unitex® Uni-Dry Cote® Harbour Fine enhances the appearance of masonry surfaces and may be sponge-finished for a concrete old world sandy surface effect or usually merely over coated with any of the range of Unitex Roll, Trowel or Brush Applied Texture coating systems.

Unitex® Uni-Dry Cote® Harbour Fine is supplied in ready-to-use 20kg bags.

Approximate coverage per bag is 2-4.5m² (as per substrate requirements).

 

Condition of Substrate

Before application of any render the surface of the substrate must be clean, dry and free of any debris. This means that any loose or damaged substrate must be removed, or patched and made good, prior to application of the base render.

The substrate surface must be cleaned free of any grease, oils, scaling laitance, efflorescence, form-oil compounds, mould, fungi, rust, dirt, dust or any other foreign matter. Pre-painted surfaces must be wire-brushed back to the bare substrate.

It is the responsibility of the Builder or Head Contractor to make good any substrate before the render is applied. Contact Unitex for advice or site visit by our representatives.

Adequate expansion joints are required to minimise cracking on the surface of the render. Location of the expansion joints is also the responsibility of the Builder or Head Contractor. Unitex® recommends expansion joints to every elevation and between different substrates, to allow for building movements and or stresses.

If such expansion joints are not provided by the Builder or Head Contractor, cracking due to movement of the substrate may occur. This is in no way indicative of faulty material. Rather it indicates sub-standard building practice.

 

Adding Water

Unitex® Uni-Dry Cote® Render products are dry powder-based products. This means that you are getting a 100% active product. All that is required is for clean water to be mixed in, on site, immediately prior to application to the substrate.

The recommended starting point is to add approx. 25% by volume, (based on the amount of powder render to be used), of water into a clean container (approx. 4.5 litres per bag). Then slowly add the powder, with drill mixing, until the desired slump (consistency) is achieved.

Unitex® Uni-Dry Cote® Harbour Fine should be left a minimum 72 hours after application and wait until fully cured and dry (moisture meter measurement no greater than 12% WME) before over coating with a texture from the Unitex Applied Finishes range.

Unitex Uni-Dry Cote® Harbour Fine:

  • Trowels on easily, smooth and up to 10mm thickness.
  • Is polymer-modified for strong adhesion to surface.
  • Is more waterproof than conventional render.
  • Just Add Water  – less margin for errors.
  • Is ideal for renovation works or over new surfaces.
  • Consistent quality.

 

Guide to Good Mixing Consistency

  1. Add the contents of the bag slowly to 4 litres of water (25% volume of entire bag) with vigorous drill mixing to ensure a lump free render of required slump.
  2. The mix can be later water thinned to required viscosity.
  3. Ensure wall surface is stable, clean, dry and free of dust, etc prior to application.
  4. For difficult masonry and non-masonry surfaces contact Unitex for product and surface preparation advice.
