What's the use of caulking agent? The paving master may not tell you these questions about caulking agent.

Sealant is one of the common materials in decoration. It can be used in the cracks of ceramic tiles to make the paving effect of ceramic tiles have better effect, and it is not so easy to hide dirt. The caulking agent has strong adhesion, small shrinkage, strong color fixation, flexible anti-crack, good decorative texture, anti-pressure wear resistance, anti-mold characteristics, so that it can perfectly repair the cracking or breakage of the floor surface, it can also be painted on the surface, with good water resistance. The caulking agent is rich in color and can be prepared by itself. It is called ceramic tile cosmetics, but many people don't know its usage. Now let's stick it firmly for everyone to popularize science!
The basic function of the caulking agent is to fully fill the gap of the ceramic tile, so in the selection of the caulking agent, special consideration should be given to the design of the seam width: the narrower the seam on the workability of the caulking agent is higher, the wider the seam on the shrinkage of the caulking agent is more stringent. Generally applicable to the joint width of more than 3mm with larger particle size filler sand. This approach can not only control shrinkage, but also reduce costs and improve wear resistance.
After caulking, a soft tool (sponge or soft cloth) can be used to rub the surface of the caulking material to make the surface of the caulking agent bright and clean. After a week or so of natural conservation can be put into use, generally winter and rainy season can be appropriately extended.
Tile sealant is the use of fine quartz sand, high-quality cement, filling pigment, additives and other composite, with beautiful and anti-seepage, anti-cracking, anti-mildew, anti-return alkali characteristics, the current cement-based color sealant, in the correct construction of the case, the color can generally maintain a relatively long time, generally maintained at more than 10 years.
Sealant dosage (kg/m)= (brick length and brick width) * brick thickness * joint width * 2/(brick length * brick width)
Dry hook is generally suitable for tile surface is not smooth, not cleaning tiles (such as split brick, sandstone, etc.), the use of tools to dry hard filler hook into the brick seam, so that it is not easy to pollute the brick surface, until the initial setting of the filler, and then use tools to pull out the smooth brick seam.
Wet hook is also called full filling, that is, the slurry is stirred well, and the slurry is filled into the brick seam with a caulking knife. A little caulking agent will remain on the surface of the ceramic tile. When the caulking agent is initially set, sponge will be used to clean and wipe the seam.
The performance of the caulking agent is: flexural strength, compressive strength, water absorption, shrinkage, wear resistance, transverse deformation rate, chemical corrosion resistance, etc., the selection of caulking agent needs to emphasize the matching with the use of the environment:
Ordinary indoor wall brick joints, the main requirements of the standard state flexural strength, shrinkage value, tensile bond strength;
Indoor floor tiles, increase the compressive strength, wear resistance requirements;
Ordinary outdoor wall tiles, in areas that may be frozen, increase water absorption and flexural strength requirements after freezing and thawing;
External insulation engineering wall tiles, but also to increase the flexibility, thermal aging after the bonding strength requirements;
Ordinary outdoor floor tiles, in areas that may be frozen, but also increase the water absorption, freeze-thaw flexural strength requirements.
Both are filling materials for ceramic tiles and stone joints, but the composition is different.
The caulking agent is composed of white cement and trace polymers and pigments. The whiteness of white is about 86%, and the surface strength is slightly higher than that of white cement, which is low in price compared to the US caulking agent.
The US sewing agent is made of high molecular polymer and high-grade pigments and special additives. It is rich in color and bright in color, and has gold, silver, pearl and stainless steel colors. It is suitable for matching with various color tiles. The whiteness of white is about 95%, the surface layer has high strength and good toughness, and will not pollute the tiles during construction, and the price is relatively expensive.
