On natural stone setts and concrete block paving, contact between the vdw 815 plus Epoxy Paving Mortar and the block surface may result in visual changes such as darkening and/or spotting. We generally recommend applying a test area first.
On some reconstitued or sensitive natural stone paving, the vdw 815 binder contact can make the stone appear darker or to have a 'wet look'. Therefore always apply a test area first.
Clean the surface thoroughly of all dirt, cement residues, vegetation, organic material or other contaminants.
Fully saturate the surface of the paving. Always use fresh and cool tap water when wetting and cleaning.
Mixing the joint mortar:
Pre-mix the aggregate, then add the binder and mix with the drill and spherical paddle mixers for approx. 3 minutes until smooth and homogeneous. Do not mix partial quantities of the product. No water should be added to the mix.
Filling the joints:
Apply immediately after mixing by pouring directly onto the pre-wetted surface. Work the mortar thoroughly into the joints using a hard rubber squeegee, whilst spraying lightly with water from a hose. The surface should be kept constantly wet during application. We recommend working from the highest to the lowest points.
Remove any excess mortar residue immediately from the area by spraying lightly with water from a hose. Be careful to clean the paved surface towards areas not yet jointed. Remove any final residual mortar with a damp coconut fibre brush. Do not brush this residual mortar into any unfilled joints. It is important to make sure that no water or residual mortar remains on the surface.
