When laying floor tiles, how much can the hollow drum rate not exceed to be considered a standard?

Before we paste tiles in the bathroom, we need to do the next step, put every small detail process in place, and paste it according to the standard construction of the floor tile on the wall, basically there will be no tile falling. The answer I gave, the floor tile on the wall may have a hollow phenomenon, but it may not fall down, choose the appropriate tile auxiliary materials, according to the process order of construction, the floor tile paste bathroom wall, will not fall off the tile.

If the bathroom floor tiles are on the wall, there are many hollows, it may not fall off, but it depends on what bricks you use, what brick accessories, if it is ordinary cement, it will definitely fall off. Due to the large weight and low water absorption rate of floor tiles, when the floor tiles are used on the wall as wall tiles, it is very easy to hollow and even fall without taking certain measures. The correct approach should be to brush the tile adhesive on the back of the floor tile, install the tile hanging piece, and use tile mortar to paste on the wall.

Among them, the role of tile adhesive is very important, and it depends on it to increase the bonding strength.

If we use traditional cement mortar to attach tiles with low water absorption, the cement mortar cannot form a mechanical lock with the back of the tile. Then the result is a large area of hollow tiles, and over time, these hollow tiles fall off directly from the wall. When we decided to use floor tiles for the wall, we had to choose a material that matched the tiles we used.

You can consult the tile manufacturer for this.

Personally, I recommend that you remove all the tiles on the bathroom wall, whether they are hollow or not. Then paste it as you would if you were reattaching the tiles. This is a requirement to re-level the wall, and then paste it according to the requirements of the thin paste method.

Another is to consider whether there is a problem with the base wall, if the construction side of the plastering ash number is not enough, cut corners, then this base layer is necessary to deal with, should be shoveled and re-plastered. If there is no problem with the base layer of the wall, then it is necessary to construct according to the standard of the floor tile on the wall, and many new materials have appeared in recent years for the full ceramic tile wall paving, that is, cement and adhesive.

It should not exceed 5%, if it is exceeded, it may cause this tile to fall off, so be sure to pay attention to maintenance.

It cannot exceed 30% to be considered a standard, and this can make the floor tiles more solid and prolong the service life.

The maximum cannot exceed 5%. If it exceeds the quality of the proof shop, it is not qualified at all, and there are many hidden dangers. Therefore, it is necessary to be careful in the process of supervising the project.

Generally, it cannot exceed 5%, if it exceeds 5%, it is very serious, and it may be caused by the lack of technology of the bricklayer.

The national standard for hollow drums of ceramic tiles is that the hollow drums of a single brick do not exceed 20%, and cannot exceed 5% of the total, and there can be no hollow tiles in the center. The phenomenon of tile hollowing is controlled within 5%, the hollow drum on the main channel must be reworked, 5% refers to the hollow drum at the corner of a single tile, and the whole tile can not be hollowed. There are many reasons for tile hollowing, it may be that the substrate is not treated well, and it may be that the quality of the material is not up to standard.

The hollow drum of a single brick shall not exceed 20%, shall not exceed 5% of the total, and the center shall not be hollow.

The hollowing phenomenon of floor tiles is controlled within 5%, and the hollow drum on the main channel must be reworked, 5% refers to the hollowing of a single corner, and the whole block shall not be hollowed.

Dear, I will answer for you, <>

The allowable hollowing rate of floor tile paving is 51%.Wall tiles: the standard of hollow drum rate of wall tiles is within 5%; 2.

Floor tiles: The standard of the hollow drum rate of the floor tiles is within 3%, 3% is the hollow drum of a single corner, and the whole tile can not appear hollow, and the main aisle of the leaky Sakura home can not appear hollow. Because the construction technology of wall tiles and floor tiles is different, there are differences in their hollowing ratio.

Second, what are the hazards of tile hollowing, which will directly affect the beauty of the wall and the ground from the surface, such as the brick may have cracks, thus losing its original decorative effect, which will directly affect the normal use of daily life. This phenomenon will damage the tiles if it is light, and if it is serious, it will affect the overall structure of the wall, which is a great safety problem. If a hollow appears on a window or balcony, cracking the hollow drum can cause water seepage on the wall.

Third, how to check the tile hollow drum can take a small wooden hammer or a small iron rod to knock on the finished tiles, in the process of knocking can not be too strong, the action should be gentle. If the sound is dull after percussion, it means that the construction effect is better, on the contrary, if it makes a crisp sound, then it means that the tile is not pasted well, and there is a hollow drum phenomenon. Fourth, how to prevent the hollowing of ceramic tiles The imagination of hollowing is caused by improper construction, so it is necessary to invite professional and skilled people to decorate during construction, and the construction standards should be strict.

For example, in the process of construction, the mortar of the adhesive layer should be dryer, and the state of scattering the bush is the best, and you can not walk on it after the construction is completed.

The wall and ground line brick paving should be mortar infiltration full, paste firmly, the wall single board corner hollow drum shall not exceed 5% of the number of paving, which means that the center of the tile hollow drum is not allowed to appear, the number of corner hollow drums does not exceed 5% of the number of tile paving in the space. Floor tiles are not allowed to be hollow! Plexus with fibers.

National standard for tile hollow drum rate 1Wall tiles: the standard of hollow drum rate of wall tiles is within 5%; 2.

Floor tiles: the standard of the hollow drum rate of the floor tiles is within 3%, 3% is the hollow drum of a single piece of sleepy corners, and the whole tile can not appear hollow, and at the same time, the main aisle of the home can not appear hollow. Because the construction technology of wall tiles and floor tiles is different, there are also differences in their hollow drum rate.

Hollow drums are not allowed.

Code for Acceptance of Construction Quality of Building Decoration Engineering (GB50210-2001)" on the hollow drum rate of wall tiles

Facing brick pasting works.

Bentan rough section is suitable for the interior wall facing brick pasting project and the high handicap attitude is not more than 100m, the seismic fortification intensity is not more than 8 degrees, and the quality acceptance master control project of the exterior wall facing brick pasting project constructed by the full adhesion method.

The facing brick paste must be firm. Inspection method: check the adhesive strength of the sample piece, test the bench reed report and construction records.

The facing brick project constructed by the full adhesive method should have no hollow drum cracks.

The bond (bonding) between the top layer and the next layer should be firm and free of hollowing.

The hollow drum area should not be greater than 400c to be qualified.

The ground hollow drum of the house is based on Article 5, 3, 4 of the Code for Quality Acceptance of Building Decoration and Decoration Engineering (GB50209 2002), "the surface layer and the next layer should be firmly combined, and there should be no hollowing and cracks". Note: The hollow drum area should not be greater than 400C, and no more than 2 places in each natural room (standard room) can be counted.

The hollow drum is caused by the presence of air in the original masonry and the powder layer, when detecting, gently knock the brick surface with the end of the drum hammer, select the four corners of the tile surface and the middle of these 5 points, if the sound is dull, there is no hollow drum, on the contrary, the sound is crisp, it is the hollow drum.

The formation of porcelain traces of the imperial brick hollow drum was originally caused by the state of Juzhou.

1. Not standard. The plastering of the base layer of the wall is not disposed of as required or the garbage of the base layer is not cleaned up. Before tile paving, check whether the plastering of the wall base meets the requirements, and the wall base debris, dust and must be cleaned.

When paving, the back of the tile is covered with cement mixed mortar or 107 cement slurry and taps the tile with a hammer handle or soft hammer to make the cement grout crowd the back of the tile, and then press hard to make the tile firmly combined with the wall base.

2. Not soaked in water. Not soaked in water or not soaked enough before paving. Tiles (especially glazed tiles) should be soaked in water for more than 2 hours before paving, so that the tiles can fully absorb water, and then take out the shade to dry or wipe the clear water.

If the brick is not saturated with water, it will absorb the water in the mortar prematurely, resulting in the mortar shrinkage and hollowing, and it will also affect the strength of the paste.
