ProRend Colourtex is a premium factory batched proprietary silicone resin thin-coat render. This attractive render is available in a wide range of colours including NCS, RAL and our own range. It is suitable for application onto the widest range of substrates with an appropriate ProRend basecoat and is available in 2 textured finishes: Uniform 1.5mm and Grained 3mm.

Ideal Substrates

• 7kN, 3.5kN and lightweight blockwork
• Existing render unpainted
• New sand and cement
• Brickwork
• Pre-cast concrete
• Render carrier board
• Insulation including: expanded polystyrene, mineral fibre, and insulated concrete form (ICF)

Features & Benefits

• Highly flexible silicone resin finish that can accommodate small movements in substrate
• Wide range of colours with increased colour-fastness due to coloured primer
• Ease of application by hand or spray machine - hand finish with ProRend Colourtex PVC float
• Highly water resistant finish due to silicone resin protect the outer skin of any property from driving rain
• Low maintenance synthetic resin finish - see below
• Ease of repair

Maintenance

ProRend Colourtex is a low maintenance render: see the benefits:

• Maintain ProRend Colourtex by power-washing to clean away and dirt or organic material.
• Overcoat ProRend Colourtex with paint to maintain the longevity of the system. Painting is required periodically at least every 12 years depending upon site conditions - refer to SAS maintenance datasheet for further details

Textures

ProRend Colourtex is available in 2 attractive textures shown below: 3mm Grained or 1.5mm Uniform.

Uniform, as the name suggests, is a tight even finish similar to that of painted sand and cement.

Grained 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.

For colour samples of either finish please contact us directly.

Colour Tinting And Matching

ProRend Colourtex is tinted at our colouring plant in the UK. The colours are based upon the popular NCS Colour System.

The standard colour range consists of popular colours which are sold throughout the UK. We are also able to provide colour matches to any RAL, NCS or BS colours.

Choose whatever colour you require and we will provide you with a sample. Alternatively, supply us with a sample colour you want matching and we will return matched samples to you.

Simple Application

The substrate must initially be prepared in accordance with the technical specification for the project. This will usually include the use of a ProRend basecoat applied to the thickness directed for the particular substrate and may include the use of ProMesh render reinforcing at an appropriate grade for the materials being used. The basecoat is flat finished as appropriate.

ProRend Colourtex Primer is applied across the entire area using brush or roller a minimum of 24 hours before the final coat.. 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 results in poor colour consistency and coverage of the final coat.

ProRend Colourtex is applied using 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.

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 Detailing

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.

Final 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:

• ProRend colour requires application 2mm thicker than the ProBead AD25 profile so that following the scraping process the render is flush with the bead
• ProRend Mineraltex follows the process described here and will not require
  the primer stage
