Silicone resin thin coat render
ProRend Colourtex is a premium, factory-batched proprietary silicone resin thin-coat render. This highly water resistant render is available in a wide range of our own colours or order a custom colour render. You can apply Colourtex render onto a wide range of substrates for a low-maintenance finish guaranteed for 10 years. This coloured render is available in two textured finishes: Uniform and Grained, and is applied over a ProRend coloured primer.
Colour Tinting and Matching
ProRend Colourtex render is tinted at our headquarters in the UK, using the international NCS Colour System.
Our standard range of popular render colours are sold throughout the UK, or we can colour match render to RAL, NCS or BS colours.
Choose a colour from our standard render colour palette below and we can send you a free sample. Alternatively, supply us with a sample colour you want matched and we will return our closest matching render samples to you.
ProRend Colourtex render is available in 2 attractive textures shown below: 1.5mm Uniform or 3mm Grained.
Colourtex Uniform render, as the name suggests, is a tight even finish similar to that of painted sand and cement.
Colourtex Grained render is a highly textured rustic finish, creating a dragged texture that can be finished in random motions or with a vertical finish to achieve a traditional alpine effect.
Free colour samples are available in either finish,
|Description||PROREND Colourtex Uniform and Grained are ready mixed silicone based finishes, manufactured from fine natural and coloured aggregates. Both are textured finishes that have excellent weather, scratch and knock resistant qualities. Maintenance is therefore minimal. Both ProRend Colourtex Uniform and Grained contain carefully selected and blended raw materials giving a consistently durable and high quality product.|
|Composition||Fine natural and coloured aggregates in a silicone binder give excellent adhesion and weatherproofing. ProRend Colourtex Uniform and Grained contain effective biocides to help preserve its attractive appearance.|
|Characteristics||ProRend Colourtex Uniform can be finished in a uniform, flat texture to a thickness of 1.5.|
ProRend Colourtex Grained can be finished in either vertical, horizontal or circular random grained textures to a 3mm thickness.Both have excellent weather resistance and durability, whilst still allowing the structure to breathe.
|Colours||12 Standard colours plus RAL, NCS, BS 4800, Sto, K Rend and Weber colour matches.|
|Reflective Values||Where intense or dark colours are used, the surface will be subject to increased thermal stress from (for example) solar radiation.|
Significant fluctuations in temperature, as experienced in temperate weather climates, will cause premature degradation in the finished surface. The dissipation of this heat will vary dependent upon the background and accordingly “reflective values” should be adhered to as follows:
|Buckets / pallet||44|
|Water maximum dilution/ L||5-10%|
|Shelf life, years||~2|
|Surface drying||24 hrs|
|L1 - Bulk density, kg/m3 ~1.60|
|Viscosity3||29,000 - 31,000 m Pas|
Uniform / Grained
|Buckets / pallet||44|
|Water maximum dilution/ L||2%|
|Coverage, m2/bucket||Uniform: ~6 - 6.5|
Grained: ~4.5 - 5
|Shelf life, years||~2|
|Surface drying||24 hrs|
|Through dry||48-72 hrs|
|L1 - Bulk density, kg/m3 ~1.70|
|Maximum grain size||mm ~3|
|Viscosity||450 m Pas|
|Water absorption coefficient||W = 0.1 kg/m2|
Prepare the substrate initially in accordance with the technical specification for the project. This will usually include the use of a ProRend render basecoat. Apply to the thickness directed for the particular substrate, this may include the use of ProMesh render reinforcing mesh at an appropriate grade for the materials being used. Flat finish the basecoat as appropriate.
Apply ProRend Colourtex Primer across the entire area using brush or roller a minimum of 24 hours before the final coat. Colourtex render can also be machine applied. Ask us about spray rendering. The primer is coloured the same as the final render coat ensuring a continuous colour; it also contains quartz which provides a fine sandpaper-like key for good adhesion of the ProRend Colourtex. Failure to use the primer can result in poor colour consistency and coverage of the final coat.
ProRend Colourtex render is applied using a hawk and trowel tight to the thickness of the grain: Uniform 1.5mm; Grained 3mm. It is important to pull the material out as much as possible to achieve the correct coverage. Always maintain a wet edge between scaffold lifts at all times.
Finish the ProRend Colourtex with a PVC finishing float, typically within 10 – 20 minutes of application, by agitating the grain to achieve the desired texture. Contact our Technical team on 01647 24620 for a detailed specification of application for your project. Note the “Simple application” guidelines provided here may not be appropriate for every substrate. SAS (Europe) Ltd take no responsibility for application based upon guidelines provided within this brochure especially when a specification has not been provided.
Ashlar detail effects can be easily created using the ProBead AD25 profile.
Initially the bead is fitted to the substrate in the same way as normal beads using mechanical fixings or render as an adhesive.
ProRend basecoat is then applied to the substrate as per the SAS specification. The finished depth of the basecoat should be the grain thickness of the ProRend Colourtex finish (1.5mm or 3mm) less than the height of the AD25 ProBead profile. The basecoat is left to dry as directed.
Following normal ProRend Colourtex application instructions the ProRend Colourtex Primer is applied using a brush or roller – see Simple Application section.
Finally the ProRend Colourtex Finish coat is applied as directed.
This method of Ashlar detailing can also be used with the ProRend Colour and ProRend Mineraltex products. For more in depth information on Ashlar Detailing please contact the SAS Technical Team.

ProRend Colourtex can also be ordered as a custom colour render. 65,000+ colours available, match to exisitng colour or any RAL, NCS or BS colours, contact us for details.
ProRend Colourtex is a low maintenance render:
- Maintain ProRend Colourtex render by power-washing to clean away any dirt or organic material.
- Overcoat ProRend Colourtex render with paint to maintain the longevity of the system when required.
Silicone renders are a modern, protective finish for your home
Colourtex silicone render comes ready-mixed, saving time. Once cured ProRrend Colourtex render is fully weatherproof, resisting rain and wind whilst letting moisture out of your home. As water rolls off and there are mold and growth resistant agents mixed in, little maintenance is needed - maybe pressure wash down once a year.
Colourtex render can be applied extremely thinly, making it extremely flexible. The frame and render move together so it doesn’t crack and keeps its durable finish. Colourtex render comes with a 10 year manufacturer’s guarantee, and you can ask us about finding a suitable applicator. Silicone renders are also easy to repair.
This render comes in the finished colour that you want, so it does not need painting. It can be painted at a later date for a change of colour or to match other walls. See above for colour choices and finishes, or ask about a custom colour render.
