Caulking agents are not only rich in colors, but can also be prepared in custom colors, so they are becoming more and more popular among people. The caulking agent can also repair cracks or damage on the floor surface. The surface can also be painted and has good waterproof properties. It can be said that there are many advantages, so everyone will definitely have a lot of questions when using caulking agents, so Zhongtaojun searched for answers to various questions about caulking agents and shared them with you. Let’s take a look. Bar!
1. What is the difference between caulking agent and caulking agent?
1. Caulking agent
The ingredients are white cement and trace amounts of polymers and pigments; the whiteness is about 86%, the surface strength is slightly higher than that of white cement, and it is cheaper than caulking agents.
2. Sewing agent
It is made of high-quality polymers, high-grade pigments and special additives. It has rich and bright colors, and has gold, silver, pearlescent and black colors. It is suitable for matching with ceramic tiles of various colors; the whiteness of white At about 95%, the surface layer has high strength and good toughness. It will not pollute the tiles during construction and is relatively expensive.
Both are filling materials for ceramic tiles and stone joints, but their ingredients are different.
2. How long does it take for caulking to be put into use?
After caulking, you can use a soft tool (sponge or soft cloth) to gently rub the surface of the caulking material to make the surface of the caulking material smooth and shiny. After a week of natural curing, it can be put into use. Generally speaking, it can be appropriately extended in winter and rainy season.
3. Does the caulking agent have any requirements on the seam width?
The basic function of the caulking agent is to fully fill the gaps in the ceramic tiles, so when choosing the caulking agent, special consideration should be given to the designed seam width: the narrower the seam, the higher the workability requirements of the grouting agent. The wider the joint, the more restrictive the amount of shrinkage the caulk can achieve. It is generally suitable to use filler sand with a larger particle size for caulking agents with a seam width of 3 mm or more. This approach not only controls shrinkage, but also reduces costs and improves wear resistance.
4. How long can the color of indoor caulking be maintained?
Tile groutIt is made of fine quartz sand, high-quality cement, pigments, additives, etc. It is beautiful and has the characteristics of anti-seepage, anti-cracking, anti-mildew, and anti-alkali return. The current cement-based color caulking agent, when constructed correctly, The color can generally be maintained for a relatively long time, generally for more than 10 years.
5. Can the same caulking agent be used in different spaces?
The performance properties of caulking agents include: flexural strength, compressive strength, water absorption, shrinkage, wear resistance, lateral deformation rate, chemical corrosion resistance, etc. When selecting caulking agents, it is necessary to emphasize matching with the use environment. Sex:
1. Ordinary interior wall brick joints mainly require standard flexural strength, shrinkage value, and tensile bonding strength;
2. Indoor floor tiles, increase the requirements for compressive strength and wear resistance;
3. For ordinary outdoor wall tiles, in areas that may be subject to freezing, the requirements for water absorption and flexural strength after freezing and thawing are increased;
4. External insulation engineering wall tiles must also increase flexibility and bonding strength requirements after thermal aging;
5. For ordinary outdoor floor tiles, in areas that may be subject to freezing, the requirements for water absorption and flexural strength after freezing and thawing must be increased.
6. Where are the dry hook and wet hook of the caulking agent?
1. Dry hook
Dry hooking is generally suitable for tiles with uneven tile surfaces that are not suitable for cleaning (such as split bricks, sandstone, etc.). Use tools to hook and fill the dry-hard caulking agent into the brick joints, so that it is not easy to contaminate the brick surface. Wait until When the caulking agent initially sets, use a tool to pull out smooth brick joints.
2. Wet hook
Wet hooking is also generally called full filling, which means mixing the slurry well and using a caulking knife to fully fill the slurry into the joints of the bricks. A small amount of caulking agent will remain on the surface of the ceramic tiles. When the caulking agent initially sets, Use a sponge to clean and wipe the seams.
7. How to calculate the caulking agent materials during indoor construction?
Caulking agent dosage (kg/m?) = (brick length + brick width) * brick thickness * joint width * 2 / (brick length * brick width)
