Ⅰ. In addition to the quality of the tile adhesive and waterproof coating, what to brush is also an important factor and an important means of construction technology. The choice of tools is good or bad, and the use of them may affect the effect of painting. Today, I will introduce to you, how to choose waterproof coating construction tools?
1. Eraser brush. The ten-brand waterproof coating is thick at the root and thin at the head, and is equipped with a rubber scraper. It is mainly suitable for drainage, around the riser, yin and yang corners and complex parts.
2. Sponge brush. A small brush with a wider surface than a rubber brush (scraper). For the construction of polyurethane waterproof coatings, large-area, one-time, large-scale reciprocating pressure can be applied. The brushes are made of sponge sheets, and many are made of rubber sheets. The waist of the brush is soft, and the brush head is recommended to be made of a material that is not easy to wear. The head is treated with a flat head or a comb. The handle should not only be sturdy, but also not easily slip, making it easier to grip.
3. Plaster with a trowel or rubber trowel. The commonly used trowel is also called a spatula. When it is used for pressing and wiping, there is a lot of material, too much force, and a lot of material. It is necessary to control the amount of force according to the flow characteristics of the material, and it is good to use it skillfully. Regarding the rubber duster, it is made from a hard rubber foam board duster shape, perforations, mounting compound on the duster base plate, uses and a wipe type duster.
4. Roller. The roller is the same as the one used for primer. Due to the high viscosity of the polyurethane waterproof coating, the fluidity of the teaching model is poor, and the leveling of the coating film is not good. When painting, if you only use a small sponge brush and a small brush for plastering, the ripples and scratches of the brush will not easily disappear. At this time, if you use the roller on top of the roller, you can get a smooth and even waterproof coating. The roller should be cleaned with solvent after construction and use, and should not be used for paint finishing.
Ⅱ. What are the specific procedures and technologies for waterproofing the ground and walls?
Ground waterproofing: laying of water and electricity lines – base treatment (leveling) – waterproof layer – cement mortar – ceramic tile; wall waterproofing: cement mortar paint – waterproof layer – tiling or paint.
