1. Prepare tools and materials
Tools to be prepared include pliers, wrenches, hammers, electric drills, spools for fixing steel wires, etc. The materials to be prepared are: cement board, cement, gelled soil nail, industrial curing agent, waterproof material, etc.
Clean the wall
Before installing the cement board, it is necessary to clean the original wall. Clean the sundries and old bricks on the wall with pliers or wrenches. Hammer the wall flat.
3. Seal the hole with cement wall.
Filling the holes in the wall with cement can ensure that the cement board is built on a very uniform and clean wall and avoid the cement board from sliding or appearing cracks.
4. Install and fix the steel wire shaft
Before installing the cement board, it is necessary to install a fixed steel wire shaft on the wall, which can ensure the fixity and stability of the cement board. Fixed steel wire shafts should be evenly distributed, and the spacing should not be too large.
5. Fix the cement board on the wall.
There are two ways to fix the cement board on the wall: one is to fix the board on the wall with cement-soil nails, and it is necessary to pay attention to accurate positioning to avoid damaging the wall and the board; Second, it is more stable to tie it tightly with steel wire and then fix it with cemented soil nails.
Apply cement
Daub cement on the cement board with a trowel. Use a trowel of normal size to evenly smear and compact the cement, and straighten it as far as possible.
7. Polishing the surface of cement board
Grind the surface of cement board with a grinder to make the surface of cement board smoother and flatter. It should be noted that you need to wear protective equipment such as masks when polishing to ensure your own safety.
8. Waterproof treatment
A layer of industrial curing agent was coated on the surface of Bo Tu cement board to make it smooth and firm. Then apply a layer of waterproof material to prevent the wall from getting wet and make the wall life longer.
The above are the steps to install the cement wall of the stairwell. Before construction, careful planning and preparation are needed to ensure the smooth progress and completion of the project. In the actual installation process, construction workers need to be patient and careful, and pay attention to safety and details.
