Installing HydroHALT into an Existing Joint
Installation Option 2.
HydroHALT may be installed into an existing joint between the ledge and wall wherein the joint width will accommodate the formation of a sealant bond of at least 6mm with both HydroHALT and the opposing shower tray or bath side wall.
If professionals installers familiar with using sealants wish to move from (202) directly to (212), draw a second horizontal wall line 20mm over the ledge. Tape down HydroHALT as shown (212). Promptly apply and spread Sealux-N between the wall lines on all sides (212-213) and press bond HydroHALT onto the walls (214-216).
NOTE 1:If using tile adhesive to bond HydroHALT to the wall, no masking tape is required. Use a thin set class C2/C2F tile adhesive mixed to a slightly more liquid than normal consistency to fully engage HydroHALT.
NOTE 2: If adhesive bed (a) will not bond HydroHALT to the wall, draw a wall line 20mm above ledge and follow details shown in images 212-216.
NOTE 3: Ensure a minimum sealant bond width of 6mm is achieved with strip and side wall after tooling. Expect joint flexibility to be reduced.
NOTE 4: Backer cord (BC1) split or whole, is pressed into the joint to provide a preferred mid-joint sealant depth of 4mm and a minimum sealant bond width of 6mm with strip and side wall after tooling (Fig. 225).
NOTE 5: The thickness of backer cord (BC2) should match the anticipated compressed tile adhesive thickness after tiling (Figs. 125/225).
SPLITTING THE BACKER CORD? Refer to Fig. 1 (last page).
WATERPROOFING? Waterproofing liquids and matting membranes should extend 50mm below the upper edge of HydroHALT (Figs. 125/225).
