GftK's vdw 815 Paving Joint Mortar is a unique, 2component, epoxy resin based, material that is designed for durable sealing of narrow joints, making it ideal for grouting porcelain paving with joint widths from 3mm, though normally recommended spacing for larger format external porcelain tiles is 58mm to avoid edge issues.
When grouting newly laid porcelain after the tiles are firmly bonded in position and strong enough to walk on, the surface must always be rinsed clean and then dried. This is also an opportune time to protect the pristine surface against future staining and resides for building works. This is done by applying NCC Porcelain Tile Protector and allowing this to dry, prior to the grouting operation.
As the video shows, mix the 2components of the GftK vdw 815+ together thoroughly until the mix is fully homogeneous, which should be for around 3 minutes. Prewet the paving and then pour out the vdw 815+ as shown, using more water to help it flow into the joints, you can't use too much water at this time. Continue moving the mortar with a rubber squeegee as it effectively selfcompacts in to the joints. Once filed leave for a few minutes and then use a wet coconut brush to remove any excess, using more water in a fine wide spray as required to remove any residual material and clean the surface. Job done!
