Waterproofing

INSTALLATION:

Corners can be installed in any order but it is recommended to install corners after walls are waterproofed and before floor.

  1. Apply thinset mortar into all sides of the corner with a trowel and embed GARDA Corner firmly into thinset making sure no air bubbles remain
  2. Wipe off excess thin set mortar protruding from seam

The thin set mortar is applied and must be appropriate for the substrate- generally an un-modified thin set mortar is used
