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.

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.
