What brand of caulk is good to buy How to see if the caulk is good or bad

The caulk brands are better: Moao, JCDecaux, Mapei, Henkel, Sika, Wanshibo and other brands, but the key problem of caulk is to pay attention to the pan alkali or color difference (for large-scale construction).

A good caulk will not crack, measure the quality of a caulk, one is its flexibility, the second is the purity of the color, the third is whether it can really achieve waterproofing, and then the anti-fouling ability and antibacterial properties.

Therefore, the poor caulk is not flexible and easy to crack, which will cause water seepage, and then the color is not right, such as white, and the poor one will be yellow, and after a while, it will be black and moldy!

There is another point to add: Moao's caulks are produced from inorganic materials, which is destined to have a long service life of Moao caulks as long as concrete.

How to use:

Pour the special stirring liquid into a clean container, slowly add the caulk, stir evenly until there is a uniform paste without corn flour, let it stand for 3-5min, and then stir.

Squeeze the mixed caulk diagonally to the reserved gap along the diagonal direction of the masonry, and scrape off the excess slurry with an oblique angle to the gap, and be careful to avoid bringing out the slurry embedded in the gap.

Allow 10-15 minutes or after the surface is dry, wipe the surface with a sponge, slightly damp cotton cloth or towel in a circular motion, and further press the caulk so that the caulk is dense and the surface is smooth.

After the caulk is dry, wipe the surface of the masonry with a sponge or a clean cotton cloth to remove the residual caulk.

When renovating. The bricklayer recommends the West card. Barrel caulk.

It is said to be very good, waterproof, mildew-proof, because some brands are not waterproof, so the bricklayer let me change Sika. In fact, it is not expensive, and the large barrel is only about 50 yuan. A bucket or two is enough.

The main ingredient of caulk is cement, which is easy to blacken, mold, and breed bacteria.

The sewing agent is a polymer that is resistant to mildew, acid and alkali, pressure and wear, and beautiful.

The Medelan is good, remember not to pick the color of the caulk is extra white and white, the effect is not good, buy the kind of ivory white that is not extra bright white. By the way, now they all use beauty sewing agent, real porcelain glue or something, water and dirt resistant, no matter what caulk is blackened for a long time. Thank you for your adoption.

Tile caulk can make up for the defects of cement and ordinary polymer mortar, because of its waterproofness, adhesion and durability, it overcomes the shortcomings of ordinary cement, waterproof mortar or ordinary wall and floor tile binder when the facing brick is not firmly bonded, hollow, cracked, falling off, water seepage, unstable performance, etc., from the waterproof plastering of building maintenance structures to the bonding of building finishing materials, waterproof have shown superior performance.

Caulk is refined from a polymer polymer synthetic resin. It is a professional caulk for green and environmentally friendly indoor and outdoor decorative brick joints. Mainly used for ceramic tiles, glazed tiles, marble and natural stone block finishes between the grout, this product has excellent crack resistance, waterproof and good durability, and can make the decorative bricks obtain a lasting and beautiful effect.

The selectivity of multiple colors satisfies the aesthetic trend of modern people to show their individuality and return to natural home life.

Caulking: 1. Use a flat rubber trowel to squeeze the stirred color anti-mildew tile grout into and fill the tile joint. The grout can only be cleaned when it is close to the initial setting.

The best time to clean is when the caulk starts to tarnish. Note: If the grout is cleaned while it is still plastic, some of the grout may be wiped off.

On the other hand, if the grout is thoroughly dried and hardened before cleaning, the surface of the tile may be damaged. 2. Use a slightly damp hard sponge to wipe off the excess grout, and constantly clean the sponge with clean water. After the grout is completely dry and hardened, a dry cloth can be used to remove the remaining powder marks on the surface of the tile.

3. In order to make the color anti-mildew tile grout can be hydrated and maintained normally, the dried brick joints should be sprayed with water in hot and windy weather. 4. If the colored anti-mildew tile grout is hardened on the tile surface due to incorrect cleaning steps.

, remove the seam with an acidic cleaner at least 10 days after it has been in use, and follow the directions.

**Contrasting Method:

There are many additives in good caulk, such as: cellulose ether, titanium dioxide, redispersible latex powder, advanced toner, etc., and these additives are relatively expensive, take toner as an example, good and bad can be more than ten times different, poor toner is easy to fade, and the performance is unstable, it is possible to run out when it meets water, and it will dye the floor tiles. The retail price of a good caulk is at least 15 yuan.

From the point of view of the outer packaging:

The quality of caulk produced by large factories is more reliable, such as: Beijing Sande, German Henkel, Guangzhou De'anmi, Guangzhou Degao and other packaging is also more exquisite, with a production date, and even anti-counterfeiting.

logo, and those bad manufacturers' products often only fight the best war, and there is not enough strength to invest in the design and production of packaging.

Look at the inner packaging and product color:

Open the package to see the inner bag, if you open it and find that the clinker packaging inside is very thin, and even the carton has the phenomenon of leakage, the quality will not be good, the caulk is generally more white, then observe the whiteness, the good caulk is whitened by titanium dioxide, and the poor caulk is whitened by double flying powder, and the whiteness of titanium dioxide is much whiter than that of double flying powder.

See the company's product brochure:

Look at the dealer whether there is a product brochure, through the product brochure and the company's address you can also see the strength of the manufacturer, the small factory is generally in a certain street, the large manufacturer is generally in a certain industrial zone. If it's a separate caulk manufacturer, you'd better not buy it, because that's usually a family workshop.

Look at the viscosity: if the above points are not confirmed well, then look at the viscosity when stirring the caulk, and the content of latex powder in the viscosity is more; Latex powders with low viscosity certainly contain very little, or even no latex powders.

Look at the brand: the easiest way is to look at the brand, the earliest foreign manufacturer of caulk is Henkel, and the best quality in China is Beijing Sande, Guangzhou De'anmi, JCDecaux caulk, Medeland caulk, etc.

The caulk has strong adhesion, small shrinkage, strong color fixation, anti-crack flexibility, good decorative texture, pressure resistance, wear resistance, and mildew resistance, so that it can perfectly repair the cracking or damage of the floor surface, and it can also be painted on the surface, with good waterproofness. Caulk is rich in color and can also be formulated by itself, so it is more and more popular with customers, and in order to achieve good results, it must be used with care.

The role of caulk:

Resist the stress caused by thermal expansion and contraction of ceramic tiles, and prevent tile hollowing and cracking.

Bright colors to improve the decorative effect and texture.

Good flexibility, pressure resistance and wear resistance.

The color adhesion is strong and not easy to fade.

The caulk has strong adhesion and good compactness, which can prevent bacteria from growing in the crevices.

Anti-mildew and anti-bacterial features.
