Construction technology, how to deal with the anti alkali of floor tile joints?

To judge the parallelism of the floor tile surface, you can put the front of the floor tile on the glass countertop, and press the four corners of the floor tile with your fingers, if the floor tile is uneven, the floor tile will shake. Or use a very thin nylon thread to pull the diagonal line of the floor tiles, and use visual inspection methods to see whether the line is close to the floor tiles, if there is a gap, it means that the floor tile surface is uneven. Check the floor tiles first, and at least 25 floor tiles should be checked.

If the floor tiles are flat, that is, the technical level of the construction party is not good.

Solution: 1. Scrape off the ash of the brick joint and re-hook the joint.

2. Use special grout agent, which is more corrosion-resistant and not easy to be alkaline.

Pansine alkali is a common disease on the surface of buildings, according to its different causes and manifestations, there are a variety of names such as frosting, whitening, whitening, frosting, wall and decorative surface erosion, etc., it is a disease phenomenon that destroys the original building materials with the change of external environment such as temperature and humidity in the soluble saline alkali of soil, adobe, brick, cement, mortar, concrete, masonry, ceramic tiles, coatings and other building materials. The degree of erosion damage is also very different, and the common phenomena are rejuvenation, foaming, pulverization, bulging, hollowing, cracking, peeling, mildew, crystallization, etc.

Cement alkali may have certain reasons related to cement quality, sand, water, air, temperature, and humidity, which is a common problem in construction.

The main reason for the anti-alkali of the wall, commonly known as cement frosting, is that the cement product calcium hydroxide reacts with carbon dioxide in the atmosphere to generate calcium carbonate and deposit it on the surface of concrete products. Or: in a solution of calcium hydroxide, a hydration product, when the water evaporates, the calcium hydroxide crystallizes in the cracks of the concrete and collects on its surface.

There are three methods, one is to use integrated wall panels, or wooden floors on the wall, or dry hanging tiles, because these methods are nailed to the wall, no matter what problems occur on the wall, it has no effect on it. Mix white vinegar or oxalic acid with water (configure 5% 10% oxalic acid solution), the water temperature is about 60, and then brush the oxalic acid solution into the seam, fully neutralize the alkalinity in the seam, and then dry, then wash, and then dry. Repeat 2 to 3 times and allow to dry.

If you want to completely cure the root cause, you must find out whether there is water leakage, such as alkali return to the exterior wall, check whether the waterproofing of the exterior wall is in place, whether the window is glued, etc. Of course, it is also possible that the upstairs neighbor's waterproofing is not done well, endangering your home. We have also encountered this phenomenon in home decoration Personal feeling that if you are in place in one step, only tile or wainscoting wall anti-alkali is very common, especially on the first floor and top floor without basement, the air on the first floor is humid, and in case of rainy days, the house is damp in addition to moisture; If you live on the top floor for a few years, the waterproofing is not repaired in time, and the rainwater gradually penetrates in, and there will still be an anti-alkali phenomenon.

If I'm not mistaken, this situation usually occurs in the bedroom next to the bathroom door or the outside equipment platform, or the bedroom next to the bathroom. This is generally caused by the lack of waterproofing. There are many reasons for this.

It may be that the developer has not done a good job of waterproofing, or it may be that the upstairs and downstairs pipes are damaged and eroded for a long time, or it may be the erosion of external rainwater, or the process is not standardized during decoration, leaving hidden dangers. Then the wall tiles penetrate the wall through the 10 cm waterproof material to the outside to form an anti-alkali outside. This kind of problem is more troublesome to deal with, you must deal with waterproofing first, and the waterproof is handled well, and the rest of the problems are not a problem.

You can buy a small shovel and carefully remove the anti-alkali from the floor, and the floor tiles will be as smooth as new.

If the floor tiles at home are anti-alkali, you can refer to the neutralization reaction in the chemistry book, which can be well eliminated, but these operations must be carried out under the condition of consulting professionals, so as not to react too intensely and burn.

In this case, it is recommended that you can use a sewing agent for filling, which can definitely be effectively avoided, and it will also make the whole ground look more classy.

Tile joints are anti-alkali to find out what the problem is! Why anti-alkali?! It should not be a large area of anti-alkali, because the cement mortar and sand used to pave the tiles, these did not complete the foundation of anti-alkali!

When the wall is alkaline, it should be treated with oxalic acid! If the tile is not a large area of anti-alkali, it is recommended to use a tool to clean the anti-alkali part of the brick joint, to deal with it thoroughly, and finally wipe it clean with a damp cloth and dry it, and then make a porcelain joint for closure!

This is a natural phenomenon. Because there is moisture in the bathroom, and then the tiles are anti-alkali.

Anti-alkali ??? Who do you listen to? Mason or project manager?

Caulk is a relatively mature product, and the quality is generally not a problem. Caulking should be done after the whole house is completed, after the first hygiene, before entering the furniture. It is estimated that the masonry is trouble-free, and the black joints were made immediately after the bricks were pasted, and then the construction was carried out, and the dust stuck to the undried caulk.

After mopping the floor, it is black, and when it dries, it will show white marks .........Can't be washed off. Try using a utility knife to cross off one layer of caulk and do another caulk or reseam.

It is beautiful, convenient and practical to coat with beautiful sewing glue.

The alkali resistance of tile crevices is mainly caused by moisture, and the common alkali resistance of tile crevices is mainly in the crevices of bathroom floor tiles and kitchen floor tiles. In addition, they are all natural cracks and there are no expansion joints, because those that have gaps will form beautiful seams, while those that have beautiful seams will not turn into alkali. For the floor tile alkali, whether the floor tile is due to water seepage, rainwater, poor waterproofness of the ground, and the wet state of the beautiful joint construction, the main reason is that the lower layer of the floor tile is wet, the cement mortar under the floor tile is in a wet state for a long time, the room is poorly ventilated, and after the chemical reaction between the moisture and the cement mortar, the alkali will pass through the cracks of the floor tile.

There is no need to worry too much about whether there are quality problems or potential safety hazards after the floor tiles are returned to alkali. This is not finished, because the floor tiles return alkali, which will affect the overall appearance. In addition, once the floor tiles are back to alkaline, we will deal with them in time to bring the floor tiles back to their normal state.

Put 60 warm water into the dissolver, then add 5%-10% oxalic acid solution according to the proportion of water, and wash the alkaline part with acid solution water with a brush. After cleaning, open the windows of the room for ventilation and let the cleaning location dry. Oxalic acid solution has a certain corrosiveness to the human body, and plastic gloves must be worn when using acid solution water to clean alkali to avoid damage.

For the alkali return part of the floor tile, it should be kept in a ventilated state for a long time to avoid returning to alkali in the future. Repeatedly wash the alkali return area with tap water and a brush until all the alkali return is cleaned. For the water washing method, it is still necessary to maintain the alkali return position for a long time in a ventilated and dry natural environment to ensure that the alkali will not be returned in the future.

It can be seen that the reason for the alkali return of the floor tile is mainly caused by the humidity of the lower layer of the floor tile. As long as the bottom layer of the floor tile is not damp, the alkali will not return naturally, and the moisture-proof, mildew-proof and waterproof functions of the caulk can be achieved. The original filling material of the floor tile gaps will be removed by the beauty sewing professionals using special tools.

If the tile gap is alkaline, then you can use white vinegar or oxalic acid mixed with water to rinse it many times, and then use a special caulk or beauty joint agent for beauty.

Lay the floor tiles of the whole bathroom first, do not pave the door stone, buy some weak acid detergent, use a thin flat shovel to remove the dirt in the gaps, and then use white cement to make mud to fill the gaps.

You can apply a smear to the wall joints, you can make an adjustment to the gaps in the wall joints, you can scrape these walls off first, and then treat the walls.

1. There are water drops on it in a short period of time after the joint, or the tile is still wet when the joint.

2. Winter construction or low-temperature construction is easy to cause indirect alkali return of ceramic tile caulk.

3. When the tile caulk is stirred, too little water is added when the tile caulk is stirred, and some powder is not fully wetted and dispersed by water.

4. After the tile bonding mortar is consolidated, the joints can be hooked, otherwise there will be anti-alkali phenomenon.

5. In the process of pasting and hooking the tiles, the sealing and capping are not carried out in time, resulting in the infiltration of rainwater and other water, or after the completion of the construction process of drilling air conditioning holes and installing rainwater pipes and pendants, the connection parts are not waterproof and sealed.

6. The high alkali content of the cement varieties in the formula and the large amount of cement added cause the alkali return phenomenon.

The way to deal with this problem is to put in 60 degrees of warm boiled water with a dissolver, and then put 5%-10% oxalic acid solution into it according to the ratio of water, and use the brush with acid solution water to clean the anti-alkali parts, and after cleaning and tidying, ventilate the room to make the cleaning parts dry. The beauty stitching method to deal with the anti-alkali of the floor tiles, the root cause of the anti-alkali factors of the floor tiles can be seen to be caused by the damp and cold under the floor tile, so as long as the floor tile is not damp and cold, of course, it will not be anti-alkali, and the waterproof, mildew-removing and moisture-proof effect of the tile caulking agent can be guaranteed.

Common problems: Oxalic acid solution has a certain corrosion on the skin of the body, so when using acid solution water to clean the alkali, you must wear plastic gloves to carry out, so as to prevent skin damage. At the same time, for the anti-alkali part of the floor tile, it is necessary to let it be in the exhaust situation for a long time, so that it is not easy to cause anti-alkali situation after that.

Common problems: In order to deal with the anti-alkali of floor tiles according to the tile joints, it is necessary to ensure that the bottom of the floor tiles has been dry, otherwise the tile joints will continue to be anti-alkali.

For the anti-alkali of the floor tiles, the best solution is to make tile polish for the gap of the floor tiles again, but it is necessary to pay attention to ensure that the bottom of the floor tiles must be dry before the construction of the seam, and ensure that the room is in a natural ventilation and natural environment for a long time after the revision of the tile seam, so that the floor tiles are not easy to re-alkali conditions. Anti-alkali is undoubtedly related to water, if you want to completely treat both the symptoms and the root causes, you must find out whether there is water seepage, such as the wall anti-alkali, to check whether the moisture-proof of the wall is guaranteed to be in place, whether the window is plastered, etc. Naturally, it is also possible that the moisture prevention of the neighbor next door on the roof is not very good, which seriously endangers your home.

We have also encountered this situation in decoration I think that only the wall tiles or solid wood wainscoting wall anti-alkali is very extensive, especially the first floor and the top floor of the building without the underground garage, the gas on the first floor is wet and cold, in case of rain, the house is moisture in addition to moisture; If you live on the top floor of the building for two years, if you don't repair it immediately after the moisture, the precipitation will slowly merge in, and the anti-alkali situation will still occur.

Can the floor tiles be retreated, or the floor can be replaced, and the floor should be waterproofed.

At this time it is better to remove the tiles and re-lay them. Under normal circumstances, the place where the alkali is serious should be re-treated.

If the situation is not serious, you can mix water and oxalic acid, and then brush it in the crevices.
