Grout construction is a relatively easy part of home decoration. What exactly is the sealant and what does it have? Some students said that the sealant was white cement and it was white. Used to fill tile joints and stick mosaics. In fact, the sealant is a building material imported from Europe.

Grout material:

The cement jointing materials include ordinary white cement, decorative white cement and general portland cement. The advantages are low price and convenient construction. The disadvantages are single color, low white cement whiteness, brick joints easily yellow and dirty, and simple cement hooks. The seam has low bond strength and is easy to pulverize, and cracks can easily occur if the seam is widened directly.

Nowadays, the construction of construction joints is basically replaced with a special sealant for tiles, but the balcony bricks can not be used to seal joints with wide seams. The cost is too high, or it must be filled with cement and sand.

When the construction is completed, it must be used after a certain proportion of fresh water is uniformly mixed with the sealant. Never dry the powder into the joint.

Scratch-knife (rubber spatula) should be used to scrape the sealant to avoid scratching the tiles with hard sand or quartz sand in the sealant.

Squeezing the grout into the seam densely

Wash the tile surface with a sponge trowel. Normal uranium tiles can be cleaned with water. If the water absorption of the tile surface is too high and the caulking agent penetrates into the tile, it needs to be cleaned with a ceramic tile cleaner.

After the tile is pasted, it is necessary to make a gap-filling agent construction for a long time, so that the gap-filling agent can fill the gap after the tile adhesive mortar shrinks. Make the filling more dense and firm. At the same time, Ca(OH)2 is produced when the cement in the mortar is hydrated, premature caulking, and the caulking agent is easy to return to alkali (ie, the surface produces “white mold” phenomenon).
