Installation and care for fibre cement

Basic Steps

You want to get the most out of cement board, so you need to install it the right way. Start by measuring your space and cutting the cement board to fit. Always use a straight edge to guide your cuts. Lay the cement board flat and make sure the surface is clean. Fasten the cement board with corrosion-resistant screws, spacing them about every eight inches. Stagger the joints for extra strength. Tape the seams with alkali-resistant mesh tape, then cover with thin-set mortar. This helps keep water out and gives you a smooth finish. If you install cement board outside, make sure you use weatherproof fasteners and seal all edges.

Tip: Always check the manufacturer’s instructions before you start. Each brand of cement board may have special steps.

Tools and Safety

When you cut cement board, you need the right tools and safety gear. Use a carbide-tipped scoring knife or a circular saw with a diamond blade. Cutting cement board creates silica dust, which can be harmful if you breathe it in. You should always wear a mask and safety glasses. Work in a well-ventilated area. Here’s a quick table to help you stay safe:

You should also wear gloves to protect your hands from rough edges. Clean up dust and scraps right away. Never cut cement board indoors unless you have a dust control system.

Maintenance

Cement board lasts a long time, but you need to take care of it. Check your cement board for cracks, chips, or loose spots at least once a year. Clean the surface with mild soap and water. Use a soft-bristle brush for tough stains. Seal joints and gaps to keep water out. Repaint cement board with high-quality exterior paint that blocks UV rays. This keeps your cement board looking fresh and strong.

• Inspect cement board regularly for damage.

• Clean with mild soap and water.

• Use a soft brush for stubborn dirt.
