Before you size and trim your cement boards, score them with your utility knife, so you have a visual aid to follow while using the jigsaw.
Alternatively, you can also use a circular saw with a special cement board blade. Some cement boards come with pre-lined grids printed on them to make it easier to score and cut. We still recommend you use a jigsaw blade to make the final cuts , rather than just a knife, as it will be quicker and more accurate.
Avoid using a wood saw or other blade not intended for this type of work, as they often create a hazardous amount of cement board dust, and your lines will not be as clean. Remember to wear protective gear, including a mask and eyewear, while cutting your boards, so you do not inhale any residue.
When cutting the cement boards, do not bury the entire jigsaw blade. Keep it short. Otherwise, you might cut out of line or overheat your saw. Before you can apply your mortar, you need to mix it and allow it to rest. To mix thinset mortar, follow these instructions:. Next, use a grooved trowel to smear thinset to your work area — but just enough for a one cement board sheet at a time. Once you have laid a thin, even layer, use the notched side of the trowel to comb ridges throughout the thinset.
While the thinset mortar is still wet, carefully place your first cement board on top of it, with the rough or embossed side of the sheet facing upward.
We recommend wearing a set of kneepads during the installation to keep yourself comfortable and steady. Using a cordless drill, secure screws along the seam of the board.
Then, insert the remaining screws every 8 to 12 inches apart over the surface of the cement board, until it is secure.
Try to make the screws flush, but a slightly raised screw should not be an issue, especially along the seam where you will soon be placing the fiberglass mesh tape. Repeat steps three through four of the installation process until all cement boards are laid, and your work area is complete. See Innovation and Impact. See Education and Training.
