1. Have you ever encountered such situations?
In an unused bathroom, the gaps between the walls and the floor are painted black, black, yellow and yellow
2. Why chasing?
◎ Mildew Prevention: The backing of the gap between tiles is cement. The pores of cement are large and easily hide dirt. When it absorbs water, it becomes moldy easily. Something like this is happening.
◎ Prevent tiles from squeezing and swelling: tiles will expand from heat and shrink from cold, so tiles can only be stretched after there is a gap left, otherwise porcelain drills are easily swollen when squeezed together.
◎ Beautiful: Compared with walls and floors that have not been poured, the tiles are different after pouring. You can see the image below, and the overall design looks more beautiful after pouring!
3. What materials are used to seal tiles?
A. Due to cheap materials and simple construction, decorating companies often used cement ash in the past to fill gaps between tiles, and white cement ash was the main one.
However, white cement ash does not have a strong bond and is easy to crack and fall off. However, if the toilet and other open waters are flushed with water for a long time, a large amount of mold and algae will form. microorganisms stick to white cement after it falls off. Health hazard. Therefore, in recent years, cement ash has rarely been used for caulking tiles.
B, glass glue
Glass glue is a widely used glue. Its main component is sodium silicate, which is water soluble and sticky. Most home glass adhesive is silicone material, which can be divided into three types: neutral glass adhesive, acidic glass adhesive, and water-based glass adhesive.
Glass adhesive is mainly used for gluing and sealing edges when decorating, there are also a few craftsmen who use glass adhesive when pouring tiles. Since glass adhesive is an organic substance, it is easy to oxidize and easily cause discoloration, mildew and peeling. The color of glass adhesive is relatively uniform, which can meet the needs of different tile colors and decoration styles. Poor quality glass glue is also hazardous to health. Therefore, glass glue has not found wide application in sealing tiles.
C, anti-mildew colored putty
Colorful anti-mildew joint filler with flexibility can absorb expansion and contraction deformation between the base and masonry, prolong the life of the finish, and can also resist the erosion of microorganisms such as mold and algae. Usually used. Colors: white, grey, black, beige, etc.
During the tiling process, the width of the gaps left by tiles with different characteristics are different, and the gap width between tiles for interior and exterior walls is also different. Thus, the colored anti-mold putty is divided into two types: fine-seam and wide-seam. The fine slotted type is generally used for laying smaller tiles indoors, and the wide slotted type is mainly used for laying larger tiles and outdoor wall tiles.
D, elastic seam agent
A traditional cosmetic agent is applied to the surface of the sealant. Leibangshi cosmetic agent does not require a sealant as a base coat and can be added directly to the gap between tiles after they are bonded. It is suitable for gap filling over 2mm, and its structure is more convenient than the conventional type. It is an advanced gap filler product. It can be used to decorate the corners of the kitchen and bathroom, and beautiful mosaic seam on wall and floor tiles, such as polished tiles, glazed tiles, antique tiles, whole body tiles, micro crystal stones, jade crystals, mosaic, etc. .
