SUBSTRATE SURFACE TREATMENT
First, we need to remove the soil, mud, dirt attached to the substrate surface, and then use a sander to completely remove the floating ash and loose concrete surface layer. Cut the slit to prepare for the later slit treatment.
APPLY PENETRABLE PRIMER
After cleaning up the base surface, it is necessary to apply a high permeability closed primer to the entire base surface. Apply the primer into the slit first to make the primer fully penetrates into the gap, and plays a good penetration role. Then apply the primer by roller coating. Be careful not to let the primer form a film and keep the surface wet.
PAINT THE MORTAR LAYER OF POLYASPARTIC COATING
The mortar coating layer of polyaspartic coating refers to that 1.5 times of quartz sand is applied in polyaspartic coating (depending on the roughness of the base surface, 1.5-2.0 times of 100-200 mesh quartz sand can be mixed appropriately). Especially the slits need to be applied with the mortar layer to prevent water vapor from rising to the top in the later stage and causing the ground to bubble.
APPLY POLYASPARTIC SELF-LEVELING LAYER
After applying the mortar layer, the ground will still be uneven. It is also necessary to apply a layer of polyaspartic self-leveling coating.
SCATTERING FLAKE
Scatter the special decorative flakes or particles when then self-leveling layer of coating is not completely dry. Remove the excess part of the flakes from the surface after curing.
