Safety Notice

Before using RASHIELD it is recommended to consult the product safety data sheet available on request

Surface Preparation

All surfaces should be duly cured, completely sound, clean, dry and dust free. Any surface contaminants like grease, oil and efflorescence must be removed in order to promote adhesion.

 

Application

Pour the contents of component A into a large clean container. Slowly ass the contents of component B and mix together with a paddle mixer on a low speed setting until a homogenous lump free mixture is obtained. Apply RASHIELD to the substrate with a trowel to a depth of no less than 2mm. Next place a fibreglass mesh directly over RASHIELD allowing the RASHIELD to completely cover the mesh. Make sure any additional layers of mesh overlap edge to edge by at least 100mm. Allow to harden for 12-24 hours. Apply the second layer of RASHIELD again to a minimum depth of 2mm.

 

Recommendations

Do not apply RASHIELD:

  • On surfaces that are excessively wet or damp
  • When temperatures are below +5°C and over +30°C
  • That has been diluted with water
