Bricklayer's skills:
A, cement mortar leveling
1, first sweep away the dust on the base, then clean it with a wire brush, brush off the mortar skin and ash layer, then brush off some sunken oil stains with 10% caustic soda aqueous solution, and rinse off the lye with clear water in time.
2. According to the horizontal line of+1000mm on the wall, measure the surface elevation downwards and bounce it on the wall.
3. Sprinkle water evenly on the ground base with a watering can.
4, according to the room around the wall pop-up surface elevation horizontal line, determine the thickness of the surface plaster, and then pull the horizontal line.
5, the application of mixer mixing mortar, color should be consistent.
6, before laying cement mortar, to besmear brushs a layer of cement slurry, besmear brushs area is not too big, increases with the increasing brush paving a layer of mortar.
7, besmear brushs cement mortar followed by cement sand, mortar spread evenly between the ash cake.
Second, the self-leveling cement leveling
1, the ground needs pretreatment first. Generally, there will be prominent places on the blank ground that need to be polished off. Generally, a grinder is needed to smooth the protrusions by rotating flat grinding.
2. After the ground is polished, it is necessary to brush the interface agent twice on the polished ground. Interfacial agent can make the self-flowing cement connect with the ground more closely.
3. Then pour the self-leveling cement. Usually the ratio of cement to water is 1:2. Ensure that the cement can flow, but not too thin, otherwise the strength is not enough and it is easy to ash. After pouring the self-leveling cement, the construction workers need to use tools to push the cement dry and push it away.
