PRORend Colour

ProRend Colour

PROREND Colour is a premium factory batched proprietary silicone monocouche render. This attractive mica containing through-colour render provides an ideal mineral finish for masonry type substrates. It has an attractive 2mm fine-scraped finish.

Ideal Substrates

  • 7kN, 3.5kN and lightweight blockwork
  • Existing render unpainted
  • New sand and cement
  • Brickwork
  • Pre-cast concrete

Features & Benefits

  • Fast application, just 1 day in best weather conditions:
    • Apply in 1 coat to specified thickness and scrape when ready
    • Spray machine or hand apply
  • Highly water resistant finish due to silicone properties that will protect the outer skin of any property from the elements
  • Reduced risk of cracking compared to other monocouche renders or traditional sand and cement due to water retention agents ensuring thorough curing
  • Reduced dusting when mixing compared to other monocouche renders
  • Apply from 15 - 25mm and cut to achieve ashlar or other detailing designs

Low Maintenance

One of the biggest benefits of ProRend Colour is the low cost of maintenance: one of the most important factors for any proprietor. See the benefits:

  • Maintain ProRend Colour by power-washing to clean away dirt or organic material. No painting required.
  • Overcoat ProRend Colour easily with a fresh look if you desire.

Application

Application

The substrate must initially be prepared in accordance with the technical specification for the project. This may include the use of an SAS basecoat or primer as directed.

Apply ProRend Colour to a thickness of 17mm in 2 passes. Apply the first coat at 7mm thick with a hawk and trowel embedding ProMesh Grade 5 around stress areas. Immediately repeat the application with a second coat at 10mm thick
so that the application is "wet on wet".

Ruling Off

Use an aluminium straight edge to rule off the wall after the second coat and spatula flat.

When the ProRend Colour is sufficiently dry it will be ready to scrape. To test the readiness to scrape mark the render with your thumb. If is ready to scrape when you can no longer mark the render with your thumb but are able to mark it with your nail: the ProRend Colour is ready but green. The time of scrape will be dependent upon
weather conditions and typically
varies from 4 - 16 hours.

Scraping

Using the nail float, sometimes called a scraper, the top 2mm of render is scraped off the wall by moving the float in circular motions to achieve a finish depth of 15mm. The wall is then brushed down gently to remove dust.

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.

Detailing

Detailing 1

ProRend Colour can be used to form many details. The same principle of cutting into the render at the point of scraping can be used to create quoin stones, key stones, feature bands and ashlar grooves.

To create a feature band battens should be fixed in place prior to any render application and a thin basecoat should be applied between the battens and left with a key. It is important that this basecoat
is thinner than the finished thickness of the
surrounding render so it will not be visible
when the finish is scraped.

Detailing 2

Apply the ProRend Colour between the battens and build up to the desired thickness. All areas must exceed the required finished thickness by a minimum of 2mm as the render needs to be scraped to achieve the final finish.

Once the finish is ready to scrape use a preformed cutting tool across the length of the entire band wearing it down to the correct form. Once fully cured the battens may be removed
and the remaining render finished to
the edge of the band.

Technical Datasheet

Description

PROREND COLOUR is a cement based, self-coloured, ready mixed render (add water), normally applied in one coat. Specifically designed to incorporate the benefits of silicone water repellents into a cementitious render system. Water is thus prevented from penetrating the masonry, while moisture accumulating inside is able to escape without problem. The silicone also prevents the migration of soluble salts through the cured render, thus combating secondary efflorescence. It is ideally suited for areas where high water repellence is required.

PROREND COLOUR can be applied from 15 - 25mm and be cut to achieve Ashlar detailing. Easy to apply and highly suitable for application by machine. Excellent adhesion on mineral backgrounds.

Composition

High quality, factory composed dry mortar according to DIN 18557 and DIN 18550. Sand according to DIN 4226. Binding agent according to DIN 1060 and 1164 and approved additives for better workability and obtaining the desired qualities.

Characteristics

PROREND COLOUR is suitable for machine and/or hand application.
PROREND COLOUR provides a water repellent - and water vapour permeable render system. PROREND COLOUR leaves a scraped through coloured finish.

Design, preparation and practical application of external rendering and internal plastering - part 1, external rendering, should be followed at all times.

Sitework:

Scaffolding must be independently tied, to allow uninterrupted application.  Any faults in the structure, particularly those which may lead to moisture penetration, must be rectified.

Site Conditions:     

Temperature range, 5-30°C.  PROREND COLOUR must not be applied to frozen or thawing supports.  If the coating must be applied in adverse weather conditions, it is essential to protect both the working area and finish before and after application.

 

Maintenance Datasheet

Description

PROREND COLOUR is a cement based, self-coloured, ready mixed render (add water).

Composition

High quality, factory composed dry mortar according to DIN 18557 and DIN 18550. Sand according to DIN 4226. Binding agent according to DIN 1060 and 1164 and approved additives for better workability and obtaining the desired qualities.

Cleaning

PROREND COLOUR may be cleaned periodically by the use of a pressure washer (40 bar) incorporating a mild detergent or road traffic film remover in the water. The spray pattern should be adjusted to form a fan rather than a jet and care must be taken at exposed edges. The interval between treatments is purely dependant upon the amount of ground floor pedestrian 'traffic' and local atmospheric conditions.

Organic growth should be brushed off the surface and subsequently treated with a good quality algaecide sterilising solution (attain advice from our technical department).

Damage

PROREND COLOUR is a through-coloured material and as such
small knocks and abrasions will not be as noticeable as with traditional painted renders.

Repairs

PROREND COLOUR is a finished material and repairs are always likely to be visible. For this reason we would recommend that full panels are removed and replaced or over coated when applicable.

In the event that the entire panel cannot be replaced or over coated the damaged area should be cleaned and made free from dust. Deep primer should be applied if material has been on the wall for a long period of time, a layer of PROREND COLOUR should be applied over the damaged area brought 2mm above the surface and left to cure. At the right stage of readiness it should be scraped back to the surface, with care taken not to scratch the existing material.

Due to the nature of the material it is unlikely that this will blend in perfectly, if this is not an acceptable match we would recommend an overcoat of Silicone paint to match the colour.

Cracking

The Code of Practice for External renderings BS5262 advises in clause 50.1 ‘Inconspicuous cracks that remain dry and sound are usually best left alone. Repairing, however carefully done, invariably results in some differences in appearance over the area of the repair'. If repairs must be carried out, entire elevations are preferable.

Painting

PROREND COLOUR is a low maintenance product. However, if PROREND COLOUR does require painting, then please contact out technical department for suitable paints on Tel: 01647 24620
