The pre-cut HardieBacker is ready to be put down on the thin-set. Since we don’t have running water yet, we chose OmniGrip thin-set because it’s pre-mixed.
The first of three pre-cut HardieBacker pieces.
The second HardieBacker piece will be placed at the end of this larger piece, beneath where the wall-mounted sink will be installed. The third piece will be at the entrance.
This is why dry fitting is so important because the backerboard is now perfectly installed on the thin-set.
Using Backer-On screws by Hardie is the next step in fastening the backerboard to the 1954 subfloor. Absolutely DO NOT use drywall screws or drywall nails on cement board; they don’t have adequate holding capacity for the combined cement board, thin-set and floor tile.
A must-have box of these screws have the ability to counter-sink in the backerboard.
There are round shallow marks on the backerboard for drilling in the screws which fasten the board to the subfloor.
The HardieBacker screws are counter-sunk so that the tile will lay perfectly flat.
After John finished drilling the screws into the backerboard, he continued applying the thin-set with his notched trowel in the last section of the subfloor (in front of the shower).
