How to control the exterior wall tiles at home from returning salt frost?

This is a normal situation, because the cement of the outer wall of the home is cracked on the outside, for example, there will be salt frost after the rain washes for a long time. At this time, you can only wash it off with detergent. Or cover the exterior walls with a cloth to protect them from rain.

The most fundamental reason for the anti-alkali of exterior wall tiles is caused by rainwater. Therefore, if we want to control the alkali return of the exterior wall tiles, we must control the rainwater of the exterior wall, first realize organized drainage, and then close the wall.

It is necessary to control the marking of cement for exterior walls, which is too low to cause salt frost, and pay attention to the quality of cement.

When pouring the floor, it is best to walk a circle of anti-beams on the entire floor, and no matter what material is used in the future, the fence with this circle of anti-beams can play a good role in retaining water!At the same time, when doing the slope of the floor, we must pay attention to making the drainage outlet to the lowest point.

Rural self-built houses do exterior wall construction application floor tile decoration design, in the hometown is more extensive, there is no doubt that the actual effect of floor tile decoration design is much better than other exterior wall decoration raw materialsHowever, many walls that apply floor tile decoration design need to encounter a problem, that is, the "salt flower" situation of exterior wall tile decoration design!

This situation will directly affect the actual effect of the exterior wall tile decoration design, so many people try their best to deal with this kind of problem correctly. The so-called floor tile "back to salt flower" is technically professional interpretation of the floor tile anti-alkali, and specifically the wall anti-alkali or the wall batch putty layer of the mixed mortar anti-alkali, condensed into a layer of milky white crystals on the surface of the floor tile, just like the old house wall under the big hometown which kind of "nitrate" situation, but the anti-alkali situation is much more obvious than the nitrate situation!

The wall anti-salt flower is the first to know why the anti-salt flower, the general alkali is due to the silicic acid in the concrete and water vapor hydration reaction to form salt soil for precipitation, when the engineering construction materials, the first floor tile is embedded with 5-8 milli gaps, the application of technical professional caulk, to block the concrete and water vapor to produce anti-salt flower conditions. When we are building a house, we first need to build a ring beam around the roof. Or there is also an upper return beam.

Complete the solution of sealing people's flat roofs around. I pick and assemble the drain point at the approximate position of the four corners of the roof and the inside of the wall.

The water collection part where the precipitation is assembled at this location is also called the rain bucket. Assemble the sewer pipes underneath the rainwater hopper. The top of the wall where the drainage pipe is fixed is assembled along the wall all the way to the top of our floor.

In the case of solving the exterior wall tiles, we must check that the floor tiles of the wall can not have cracks. Crack wall tiles should be replaced as soon as possible. Tile seams or sealants are carried out after thatIt is necessary to be careful and careful, and do not allow degumming, missing beating, and breaking off these problems.

The key is to check the handover between the top end of the floor tile and the wall.

1.The prevention method is: brush oxalic acid twice after the substrate is cleaned, and brush another after the completion of the wall tile priming process. (Since the time between priming and sticking the bricks is too short, this layer can be improved appropriately).

2.Cement does not use ordinary Portland cement as much as possible, this kind of cement has high early strength and high alkali content (mainly a mixture of calcium hydroxide and calcium oxide), and the probability of this phenomenon is greatly increased.

3.The large ones are shoveled off little by little with a small shovel, and the remaining traces can be dipped in a damp rag with vinegar and wiped back and forth, because the cement is alkaline, how much acid can be neutralized, and it will be gone after a few more wipes. Wear gloves when operating.

The best thing to do is to waterproof the walls before tiling, so that there is no salt frost.
