1. Magnesium oxide causes
A large amount of magnesium oxide appears on the back of the tile, because magnesium oxide is powdery, very It is easy to affect the bonding performance of tile mortar and ceramic tile. Please clean the magnesium oxide before construction.
Second, the base layer is not solidified or not cleaned
The wall base plaster is not treated as required or the base waste is not cleaned. Before the tile is laid, check whether the base plastering of the wall meets the requirements. The wall base debris, dust and must be cleaned. If the base surface is not cured enough, the base layer is cured and then laid, such as the base. If it is not cleaned, it will affect the bonding performance of the tile mortar and the base surface like magnesium oxide. The wall surface is not cured enough, which may easily lead to delamination of the base surface after the paving, which may cause the tile to empty or fall off.
Third, the construction method is not correct
& emsp; & emsp; & emsp; Because many construction workers used the old cement tile method, the result is still using cement construction when using tile adhesive The paving is carried out without professional training and the use of professional toothed scraper construction. The use of special construction tools is not conducive to the elimination of air, which can easily lead to the falling off of tiles and empty drums. Therefore, each cooperation with a project advocates free technical training to avoid brickwork or even falling off due to improper construction methods.
Use professional scraper tools:
Use the toothed scraper to comb the tile glue to the base layer, which is good for air elimination. At the same time, the selection of tooth squeegees of different sizes can effectively control the amount of glue and control the thickness of the adhesive layer. It should be noted that the large tooth mouth is used for attaching large tiles and heavy bricks. For ordinary home decoration, it is enough to use a small toothed scraper.
The correct way
Fourth, the slurry is not enough.
The slurry rate is the guarantee of product performance, and of course the guarantee of engineering quality. In the product self-test, Olympia conducted in-depth research on various kinds of stickers. The proportion of bricks and drums caused by the dissatisfaction of the pulp is higher, because the tile is the combination of the brick and the base. Therefore, in the case where the product guarantees that the two-way adhesion is strong enough, the slurry filling rate is particularly important for the laying of tiles:
If the filling rate is not enough, the pole It is easy to generate bubbles in the air, and the bubbles will form an empty drum after solidification. If the large area of the tile glue is not enough, it means that the bonding surface of the tile adhesive is missing in a large area, which may affect the quality of the project and affect the industry reputation of the construction unit.
5, tile adhesive blending cement
tile glue is a new type of adhesive that replaces old paving materials such as cement, sticky The knotting force is several times that of cement mortar. Ouiya tile adhesive tile tiling does not need to be blended with cement. Of course, some construction parties may choose to blend ceramic tile with cement to save material cost. This approach is wrong.
Tile adhesives are produced by scientific matching. If blended with cement, the bond strength, water retention, shrinkage and anti-slip properties of the tile adhesive will be The discount was greatly reduced, which led to emptying and falling off, which further led to delays in construction period and increased labor and economic costs.
Six, inferior tile adhesive products
tile adhesive as a new type of bonding material for cement tile, its formulation and raw material requirements All of them need to be extremely rigorous. The small tile adhesive brand tiles on the market are mixed, and the quality of the products is not fully guaranteed.
If a site in Guangzhou purchased a batch of tile adhesives produced by small manufacturers, the product was not inspected during the purchase process, resulting in a large area of tiled tiles. The phenomenon of small area falling off, when the construction unit feedbacks the information to the manufacturer, the manufacturer can’t give a solution, and the buyer finds the address of the manufacturer according to the address and finds it is a small workshop and has already slipped away.
Suggestion: Purchasing compliance brand brand tile adhesive, large brand tile adhesive has sufficient technical research and development team, good social responsibility, ability to conduct pre-construction product testing and construction training, these small brands are not powerless And financial resources to run such a professional team.
