Uni-Marble Grain is an acrylic bound stone tough, natural coloured aggregate finish. The acrylic bound coloured aggregate pre-mix is applied to smooth substrates in a thickness equal to or great than the particle size of the coarsest aggregate, and then thoroughly rubbed up to yield an even surface.

Unitex Uni-Marble-Grain allows for a smooth multi coloured glistening stone effect to enhance the style of especially large concrete structure externals as well as foyers and lobbies. The Unitex Uni-Marble-Grain glistening finish converts what would be dull cement structures into interesting fresh marble towers. Both the protective and decorative functions of the Unitex Uni- Marble-Grain finish are long term and will normally remain so for long-life.  Hence the Specifier is provided with a virtually maintenance free long-life coating. At ground level (trafficked areas) on commercial projects, Unitex recommends overcoating with a protective exterior grade high gloss surface sealer. Unitex Uni-Marble-Grain protects and decorates new and restores old surfaces such as, interior and exterior walls; balustrades; beams; columns; and infill panels; as well as entrances and lobbies. Unitex Uni-Marble-Grain is suitable for use over rendered surfaces such as, brick; cement blocks; fibre cement sheets; and aerated concrete.

Unitex Uni-Marble Grain consists of washed and graded granular marble chips of specified size to give the desired texture and natural colour mix. The marble grains are bound tightly together and also adhered to the substrate by a special adhesion promoted acrylic resin.  The resin allows the Unitex Uni-Marble-Grain high build film to retain enough flexibility to cope with normal substrate movement yet retain a tough impact resistant surface effect.

Unitex Uni-Marble Grain is available only in a range of naturally obtainable stone colour finishes. You only see the natural stone. Coverage is approximately 3-3.5m² per 15 litre pail.

Unitex Uni-Marble Grain:

Biological Resistance 

Resistance to attack from bacteria and fungi is provided. This product being a water based acrylic system offers safe handling and low toxicity properties. Dirt, grime and dust on the surface of coatings will act as seed beds for bacterial attack, therefore cleaning and maintenance of your coating is essential to hinder bacterial and fungal attack.

Fire Resistance 

The full Unitex coating system when subjected to the Early Fire Hazard Tests – Australian Standard AS1530.3:1999 meets the strictest standards.

Water Resistance

The coating is formulated with a low water vapour permeability factor to allow migration of water vapour from the substrate, but the coating film forms a low permeation barrier to external rain and moisture. Rising damp and elevated levels of moisture in the substrate will damage, and possibly delaminate, the surface coating.  Please ensure that damp coursing the substrate is in place and prior test moisture content with a moisture meter (maximum 12% WME is allowed) (Builder responsibility).

Unitex Uni-Marble Grain exhibits excellent durability and colour retention under all climatic conditions. A minimum protective and decorative service life of 7 years is provided.  Durability under normal circumstances is limited only by the life of the substrate. Unitex Uni-Marble-Grain is self-priming due to the excellent wet adhesion properties of the acrylic resin. The colour of the finished surface is dependent on the natural colour of the marble chips and as they are mixed in a clear acrylic matrix, a coloured Unitex Uni-Substrate Sealer below the Unitex Uni-Marble Grain is required. The Unitex Uni-Substrate Sealer must evenly colour coat the substrate to provide uniformity of colour in the top coat Unitex Uni-Marble Grain.

Application Details 

A minimum of 72 hours, under ideal temperate conditions, is required for through-dry (and cure) of the render, when the surface is through dry the Uni-Marble-Grain may be applied. Dry is measured to be less than 12% WME (Wood Moisture Equivalent) where measured on a Protimeter® Moisture Meter.

The substrate must be clean before applying the Finish coat. Any crumbling, loose or damaged substrate render must be removed and the surface patched and made good prior to coating. All surfaces must be free of grease, oils, dirt and dust. Pre-painted surfaces must have flaking paint wire brushed back to a sound substrate. Unitex recommends a base coat of a pigmented substrate sealer (2 coats) over old renders prior to application of the surface finishes. All Unitex Uni-Marble Grain marble chip finishes will require a pigmented sealer coat (Unitex Uni-Substrate Sealer) prior to applying the Uni-Marble-Grain finish.

Application should not be carried out under excessively cold conditions (below 7 °C) or in hot windy conditions (above 32°C).Drying  Uni Marble grain must be protected for minimum 48 hours after application (overnight condensation and rain damage etc). Site Unitex strongly advises sign off on all coating systems. Always provide the Builder and Designer with a site texture sample of minimum 2m², finish and colour for written approval nominated the Unitex specified system
