Preparation of the substrate

Any uneven joints should be ground flat and sandblasted. If sandblasting is not appropriate, any other rust removing process is sufficient. In the case of a concrete substrate, holes should be filled. The surface should be sandblasted or ground flat, dried thoroughly, and washed with an acid solution if necessary.The finished surface roughness should be within the range of 50 ~ 100um.

Primary coating

It is usual for the priming coat to be the same resin as that to be used for the main coating. It is recommended that the priming coat be applied with brush, roller or airless spray, to a thickness of 30 ~ 40um.

Secondary coating

The secondary coating,containing the glass flake, is normally applied to a thickness of 700 ~ 1000um; however thicknesses up to 2mm should be applied in very corrosive environments. Application is normally by trowel or similar.
