Installation Guide


Step 1

Set the frame to the desired level (top of Wundercover 3-5mm below finished surface). Orientate to best suit the pattern of the pavers (optional). Plaster all gaps and make sure entire frame base is fully supported. Leave sufficient depth for pavers to fit over external flanges.

Step 2

Once the plaster is firm, the pavers can be laid and cut neatly to the edge of the frame.
