Application Information
Instructions for use

Surface Preparation

The surface of the concrete shall be sound, clean and uncontaminated.  This preparation shall be such as to leave a sound exposed concrete surface free from dust, loose particles and any deleterious matter.

Application

COLMEFOAM HD should be applied with a multi-component spray system. Upon contact with the surface, the mixture instantly adheres and expands into a rigid foam.

Recommendations

  • The thickness of each applied layer should be between 1cm and 4cm in order to maintain an adequate dimensional stability .
  • It is not recommmended to apply thicker layers
  • The distance from the spray gun to the substrate is recommended to be approximately 80cm.
Additional Information
Health & Safety

During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.

In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.

If ingested, obtain medical attention immediately. Do not induce vomiting.

Refer to MSDS for more detailed safety instructions.
