Tiles are a big part of the process of decorating a house. And there are more and more types, from glazed tiles, to glass tiles, to fully glazed tiles and microcrystalline stone. Paving techniques also from the earliest emergence of cement mortar or fast sticky powder point sticky, to later use on-site mixing cement mortar in the back of the brick paving on the wall after paving. And now widely favoured by the home improvement company thin paste method of paving, paving methods are also increasingly advanced.

The drum in the tiling time more or less will appear, today to give you about the discovery of tile drum processing methods, welcome you to add to discuss.

1.First of all, a brief explanation of what is a tile bulge?

Inadequate contact between the tiles and the wall floor, resulting in loss of support, load bearing leading to peeling, arching, inability to drill, cracking and other problems. Please see the diagram below.

Most of the drums appear in one or more of the four corners of the tile. Here to teach you a check method — five-point knocking detection method: using a metal rod to knock on the four corners of the tile and the central part of the tile, by knocking out the sound to determine whether the tile is hollow drum. If the knocking sound is relatively dull, it means that the paving is more solid and more solid. On the other hand, if the sound is “thud”, it means that the wall and floor tiles are not paved firmly and there is a hollow drum.
Drum rate is also a standard, ground tile drum rate should be controlled within 3%, the main channel can not appear drum; wall tile drum need to be controlled within 5%, that is, a tile drum area can not exceed 5% of the tile area.

Warm tip: As tiles just tiled when generally can not check, and the drum often occurs in the process of tiling good dry, so generally have to be tiled after the second or third day to check. In the process of tiling more to go to the site, bring a small hammer, tiling after 1 day 2 days can be checked, while the master is still in the rush acceptance report problems! On the spot processing time is short, low cost, high efficiency!

2.Why is there a drum?

Now the floor tile construction is mostly dry paste method (that is, semi-dry cement mortar priming, dry before using plain cement or tile adhesive), there are many reasons for hollow drums.

Uneven and unclean walls

Thinly tiled walls must be levelled at the grassroots level, uneven wall base, too much bump and undulation will make the contact between the tiles and the wall inadequate, resulting in hollow drums. Insufficient strength of the base wall, oil stains, loose base wall will directly affect the bonding power of the tile adhesive, resulting in hollow drums or even fall off.

Mixing cement mortar with tile adhesive

The finished adhesive has a ratio of various components, so adding materials at will change the ratio, destroying the stability of the material, and the tiles will bulge and fall off after use.

Stirring with a shovel on the ground or in a frying pan

The tile binder has a professional material ratio, which needs to be stirred with a mixer, and cannot be stirred evenly with a shovel, as the active ingredients inside the tile binder cannot be fully integrated; at the same time it is difficult to grasp the amount of water added by manual spreading and mixing. Changed material ratios, resulting in a decrease in bonding power.

Tile binder soaking water use

Just contact tile binder many workers master or used to soak cement method, mix good tile binder in the bucket for soaking, afraid of material dry too fast, in fact, doing so will lead to tile binder absorbing too much water no strength, chalking, tile easy hollow drum off.

Too long after mixing, add water again and mix for use

Once the tile adhesive has been mixed with water, the active ingredients begin to react chemically to produce adhesion. This reaction time is fixed and will not be extended by adding water again. Stirring with water again only changes its form, and using it in this way can lead to tiles bulging and peeling. The bonding agent should also be used as much as possible, stirred and used for a controlled period of 2 hours after mixing, and discarded after setting.

Too large an area on the wall at one time

If the wall surface is too large for the adhesive, the surface layer will be cured and then tiled, which will lead to bulging and peeling. The wall should be pre-wetted when the wall is dry.

Uneven scraping of tile binder

Tile bonding agent scraping is not uniform, tile and wall after tiling is not a comprehensive contact, will lead to paste after flatness is not enough, tile surface cracking, taut porcelain, hollow drum, off. Different sizes of tiles, according to the guidance of the adhesive manufacturer to choose different models of tooth-type spatula, paving to knead pressure in place, adjust the flatness. And 24 hours after the completion of paving for hooking.
