ProRend Mineraltex is a cement-based, ready-mixed render (with the addition of water), designed for application over ProRend basecoats. Designed to incorporate the benefits of a thin coat render into a cementitious render system. It prevents water from penetrating the masonry, while moisture accumulating inside is able to escape without a problem. Scratch- and chip-proof, remaining malleable and easily workable. It is also weather-resistant against driving rain, robust, and resistant to industrial and air pollution.

The render incorporates 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.

The product is applied to the thickness of the grain and finished with a Mineraltex sponge float. Once fully cured, it can be painted with silicone paint (see reflective values).

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:

  • ProWall or other ventilated cement board systems and masonry cavity walls: >5% clarity.
  • ProRend EIFS insulation systems and masonry solid walls: >20% clarity.

Applications:

  • For medium-density blockwork with normal suction apply onto a backing of ProRend Float.
  • For aerated concrete and low-density blocks, apply onto a backing of ProRend Prep and ProRend Float.
  • For high-density masonry and concrete, apply onto a backing of ProRend Prep and ProRend Float.
  • For ProWall and ProRend EIFS, apply onto a backing of ProRend Lite.
