Professional Installers

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).


 

instalaltion_option2-finalNOTE 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).
