SUBSTRATE PREPARATION
Preconditions
Confirm waiting time to overcoating has been achieved for the previously applied system base layer.
- If the maximum overcoating time of the base layer is exceeded, prepare the surface of the existing coating using mechanical grinding equipment. Note Depending on the type of base layer, a solvent wipe may also be required. Contact Sika Technical Services for advice.
- Remove dust and contamination from the prepared surface using vacuum extraction equipment.
MIXING
IMPORTANT
Do not dilute with solvent or water.
TOP COAT MIXING PROCEDURE
- Mix Part A (resin) until the coloured pigment is dispersed and a uniform colour is achieved.
- Add Part B (hardener) to Part A.
- IMPORTANT Do not mix excessively. Mix Part A + B continuously for ~3 minutes until a uniformly coloured mix is achieved.
- To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
- During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing.
APPLICATION
IMPORTANT
Application by trained personnel
The application of this Product must only be carried out by an applicator that is trained or approved by Sika. The applicator must also be experienced in this type of application.
IMPORTANT
Risk of fumes entering air conditioning units
