1. Basic treatment: Before construction, it is necessary to check whether the wall surface is smooth and free from cracks and hollows. If cracks need to be filled, they should be knocked empty drum and compacted.
2. Material preparation: The sand in the water is heavy, so it is necessary to prepare enough materials. At the same time, there must be construction tools, such as mud knives and nails.
3. Primer: First coat the primer. Before the primer dries completely, coat the surface of the primer with mesh glue, and then cover the whole wall with glass fiber mesh. After drying, batch putty with a certain thickness on the wall with a spatula. After the putty is dry, polish it with a spatula.
4. Sand-in-water construction: After pouring the sand-in-water into clear water and stirring it evenly, smear the sand-in-water on the wall with a trowel, paying attention to the appropriate and even thickness. After applying one side at a time, wait for it to dry before proceeding to the next operation.
5. Waterproofing agent: After the water sand is dry, apply waterproofing agent to improve the waterproof performance of the wall.
