Decrypt the tile empty drum, the truth of separation!

Now decoration of the house, tiles in the home decoration more and more widely used, the variety is also more and more, from glazed brick, to glass brick, to all glazed brick and microcrystalline. Paving techniques also from the early emergence of cement mortar or fast sticky powder point stick, to later use the site stirring cement mortar in the back of the brick paving after the wall tile, and now widely favored by home companies tile adhesive patching, paving method is also more and more advanced.
you know why the tiles on the walls of your house are smouldering as soon as they hit? Did you know that the tiles on your home will fall off?
home tiles fall off is not a play, hurt people have to lose, then you know the tile "disobedient" reason? Let's talk about the tiles today. . .
As the saying goes, good ingredients with good work, now to everyone listed a few in the use of tile adhesive a few misunderstandings, decrypt the home wall brick will have a smouldering sound and tile off the brick truth!
1, the wall is not flat, unclean
thin paste wall grass must find flat, wall grass is not flat, bumps and bumps too large will make the tile and wall contact is not sufficient, resulting in empty drum
China
.
the strength of the grass-roots wall is not enough, oily, loose grass-roots wall will directly affect the bonding force of the tile binder, resulting in empty drums or even fall off.
2, tile binder inside mixed with cement mortar
the finished adhesive inside the various ingredients are matched, random addition of materials will change the ratio, destroy the stability of the material, after use of tiles will be empty drum, fall off.
3, with a spade on the ground or stir-frying plate
tile binder has a professional material ratio, need to be stirred with agitator, with a spade can not be stirred evenly, the active ingredients inside the tile binder can not be fully integrated; The material ratio is changed, resulting in a decrease in bonding force.
4, tile binder bubble water use
just contact with the tile binder many workers master or accustomed to the method of foaming cement, the stirring good tile binder in the bucket to soak, afraid of the material dry too fast, in fact, this will lead to the tile binder absorbs too much water without strength, powdering, tiles easy empty drum off.
5, after stirring time is too long, re-water stirring use
tile adhesive in the water mixing after the completion of the active ingredients began to occur chemical reactions, the adhesion force, this reaction time is fixed, will not be extended with the re-addition of water stirring, re-water stirring only changed its form, so that the use will lead to the tile empty drum, shedding, adhesive should also be how much stirring, stirring time control after 2 hours, after solidification treatment.
6, the wall scraping area is too large
the wall binder batch scraping area is too large, the surface solidified and then the brick will lead to empty drums, fall off;
7, tile binder batch scraping uneven
tile adhesive batch scraping is not uniform, tile and wall is not a full contact, will lead to paste after flatness is not enough, brick cracking, taut porcelain, empty drum, off. Bricks of different sizes, according to the guidance of adhesive manufacturers to choose different types of tooth-type smears, when laying to knead in place, adjust the flatness, and after 24 hours of paving completion of the stitching.
note
tile adhesive stirring, scraping and paving to meet the requirements at the same time, to ensure the quality and effect of the paving, tile treatment is also the key.
We will find that after opening the tile packaging, the back of the brick will appear white, hands will be stained with a layer of white powder, this is the tile release agent, clean will make the tile empty drum, fall off.
the main component of the back of the brick is magnesium oxide, with high temperature resistance, and this layer of magnesium oxide if not cleaned, but also in the laying of the anti-adhesive reaction.
how do you remove magnesium oxide from the bottom of a brick embryo?
Before paving, experienced tiler will pay attention to see if the back of the brick is residual release agent composition, if there is, generally use an iron brush to remove the release agent on the back of the brick, or wipe with a clean wet towel.
