ProRend Mineraltex
ProRend Mineraltex is a premium factory batched proprietary mineral thin-coat render. This attractive through-colour render provides an ideal mineral finish for masonry type substrates and has an attractive 2mm uniform finish.
Ideal Substrates
- 7kN, 3.5kN and lightweight blockwork
- Existing render unpainted
- New sand and cement
- Brickwork
- Pre-cast concrete
Features & Benefits
- Ideal large developer render system: saves time and money compared to traditional sand and cement or monocouche renders
- Hand apply with hawk and trowel: finish with ProRend Mineraltex sponge float
- Speed of application - cover large areas quickly
- Low tension render system due to 2 coat application
- Low maintenance mineral finish - see below
- Ease of repair
Maintenance
ProRend Mineraltex is a low maintenance render: see the benefits:
- Maintain ProRend Mineraltex 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 - 14 years depending upon site conditions - refer to SAS maintenance datasheet for further details
Simple Application
The substrate must initially be prepared in accordance with the technical specification for the project. This will include the use of an SAS 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 Mineraltex is applied using hawk and trowel tight to the thickness of the grain: 2mm. 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 Mineraltex with a sponge 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 Detailing
ProRend Mineraltex can be used to form such details as ashlar which can be used to create a block effect.
Initially the ProRend basecoat is applied to the substrate as per SAS specification. The basecoat is left until the surface hardens, typically a couple of hours.
Battens are fixed to the façade in line with the location of the cuts. The ashlar cut is then made using the ashlar detail tool and an appropriate shaped cutter - V shaped and square cutters are the most common.
The basecoat is left to dry as directed prior to the application of the ProRend Mineraltex coat using hawk and trowel. This is based upon the same method included in the Simple Application guide in the brochure.
This method of Ashlar detailing can also be used with the ProRend Colour and ProRend Colourtex products:
- ProRend Colour requires standard application and scraping as directed. The ashlar detail tool is used in the same way as the basecoat described above.
- ProRend Colourtex follows the process described here and requires the additional primer coat before finish application.
For more in depth information on Ashlar Detailing with ProRend Mineraltex please contact the SAS Technical Team, or for information about training on the application of these details please see details of the ProRend Training College.

Technical Datasheet
Description:
PROREND MINERALTEX is a cement based, through coloured, ready mixed render (add water), designed for application over a base coat of PROREND RAPID or other PROREND basecoat as specified. Specifically designed to incorporate the benefits of a thin coat render into a cementitious render system. Water is thus prevented from penetrating the masonry, while moisture accumulating inside is able to escape without problem.
PROREND MINERALTEX is to be applied to the thickness of the grain and finished with a Mineraltex sponge float.
Composition:
A premium industrially-produced stone finishing plaster, based on bonding agents of white lime hydrate, white cement, white marble stone and lightweight additives with a variable grainy texture.
Characteristics:
PROREND MINERALTEX is suitable for hand application.
PROREND MINERALTEX is a low-maintenance plaster that is scratch-proof and chip-proof, remaining malleable and easy to work. It is also weather-resistant against driving rain, robust and resistant to industrial and air pollution.
Colours:
4 standard: white, ivory, cream, wheat

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 MINERALTEX 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.
Substrate:
PROREND MINERALTEX is designed to be applied to a base of PROREND RAPID which can be applied as a one coat render on medium density blockwork with normal suction. For alternate substrates please consult the SAS Technical Team.
