Test surface

On some natural and concrete stone slabs, contact between vdw 815 plus joint mortar and the stone surface may cause visual changes such as darkening and/or staining. We generally recommend creating a test surface. If necessary, we recommend using vdw 950 Steinschutz 3 in 1.

Preparation

• Clean the surface of the object to be jointed thoroughly, free of residues.
• Pre-wet slabs thoroughly. When pre-wetting and cleaning, always use clean, cold tap water.
• Mixing the joint mortar: pre-mix mineral components, then add binder and mix homogenously with a drill and mixing paddle for approx. 3 minutes. Unmixed components must not be processed. Do not add water to the mixture.

Filling the joints

Immediately fill the joints with the mortar using a rubber trowel, preferably diagonally to the joint. The joint mortar’s fluidity can be increased with a water spray. During processing, keep the surface constantly moist. It is recommended to work from the highest point in the direction of fall.

Cleaning

Remove excess mortar immediately with a light, continuous water spray until the surface is completely clean. Ensure cleaning is done in the direction of still-unjointed areas. Sweep off remaining mortar with a damp coconut broom. Do not sweep residual mortar into still-open joints. Ensure that neither rinse water nor mortar residues remain on the surface.
