Rack-Shaped Mortar Layer Uneven?

1. the batch scraping mortar thickness is not enough.
2. the tooth hole has already dry the gum slurry should clean the tooth type scraper.
3. slow the scraping speed.
4. the adhesive mixing uneven, should be fully stirred mortar.

Inspection Found that the Back of the Tile is not Glue or Adhesive Area?

1. hot and dry weather, and each batch of scraping area too large, resulting in part of the surface water loss of rubber slurry.
2. should reduce the size of each batch of scraping mortar, with no light touch without adhesive paste, should be scrapped after the paste.

On the Back of the Empty Drum Phenomenon?

1. the use of larger size toothed scraper.
2. Increase the inclination of the tooth type scraper and the base surface.

Is Bond not Firm?

1. the base surface has loose material (dust, etc.), should clear clean.
2. there is water, should suck dry to no water.
3. oil, grease, should be clean.

When Pasting Tiles or Stones Fall?

1. slurry is too dilute when opening the slurry should be proportional to add water.
2. tile or stone weight is too large, should be from the bottom of the construction.

Is there an Empty Drum During the Check?

1. has exceeded the adjustment time forcibly adjusts, takes out the filling slurry.
2. mortar thickness is not enough, need to fill slurry.

Lack of Adhesion?

1. the choice of ceramic tile model is improper, as described in the use.
2. slurry mixing uneven.

Paste Tiles, Why Should not Use 107 Glue?

1. 107 glue is the organic polymer, with the evaporation of water, in its own polymerization of the intensity, but also produce shrinkage, in the contraction process to produce cracks, resulting in leakage.
2. cannot withstand the freezing and thawing circulation, forms the shell to fall off.
3. the construction difficulty, the cleaning work also has the certain difficulty.
4. easy to be affected by man-made, construction quality is not guaranteed.
5. weather ability and durability of poor, fast failure.
6. contain harmful ingredients, endanger health.

Cement Paste or Cement Mortar Pasted Tiles are those Dangerous?

1. the adhesive strength is low, the tensile strength only 0.08~0.1Mpa, shear strength is only 0.4Mpa, far less than the state of the tile and stone paste installation standards.
2. produces the dry shrinkage, causes the empty drum, falls off.
3. water resistance and low-temperature resistance.
4. can't withstand the freeze-thaw cycle.

What is the Reverse Pulp Hanging Tears? How to Solve the Problem of Anti-Slurry Hanging Tears?

Question 10  What is the reverse pulp hanging tears? How to solve the problem of anti-slurry hanging tears?
1. the cement mortar in the hardening process will produce a lot of holes, these cavities are water leakage channel.
2. the cement mortar in the deformation and temperature action will produce cracks.
3. cement mortar due to dry shrinkage and some construction factors, easy to form in the ceramic tile empty drum.
4. water in the cracks and empty drum parts of the dissolution of the erosion, that is, external seepage will cement the CAO dissolved precipitate, become CA (OH) 2. Through the pores of a tile or stone and forming a CaCO3 on its surface, such as the dissolution of the mud, which is usually said to hang tears.
5. Tile glue will be on the back of the tile and the surface of the substrate to form bonding film and plug its capillary pores, so as to block the water channel, thus avoiding water erosion. Another ceramic tile adhesive has excellent flexibility, can prevent the bonding layer cracking.
6. the use of ceramic tile adhesive paste technology, so that ceramic tile or stone, and the formation of a uniform between the free cavity of the bonding layer, to prevent water seepage, anti-slurry hanging tears effect.
