High stress points such as wall/floor junctions and joints must have Sovereign Flexi Tape embedded in the first coat of the membrane. Areas directly under shower enclosures should have Sovereign Scrim Sheet embedded into the coating. This is achieved by coating the area and bedding the tape/scrim into the wet coating. This should then be over coated with more of the Watertite.
