Scraping glue in rainy days

Ceramic tile adhesive is an important material for ceramic tile pasting, but there are many misunderstandings to be avoided in the use process. This paper will introduce the matters needing attention in the use of tile adhesive in detail to help you avoid the problems in the pasting process.

Don't dope with other materials.

Don't mix cement, mortar and other materials into the tile glue water. Doing so will destroy the proportion of the original production components, leading to unstable quality, and there may be empty drums and peeling when sticking bricks.

Don't mix and stir with a shovel

Never put tile glue on the ground and mix it with a shovel. Mixing with shovel can not get uniform mucilage, which will lead to the loss of effective components; The proportion of water added by manual stirring is also difficult to be accurate, which will reduce the adhesion of ceramic tile adhesive.

Do not soak in water for a long time.

Do not soak the tile glue in water for a long time. It is wrong to use it by soaking cement. Putting the prepared tile glue on the ground or in a bucket for a long time will easily lead to the loss of strength, powder and bricks of the tile glue.

Don't reuse it

Ceramic tile glue has been used for a long time, so it is not advisable to mix water with ceramic tile glue before using it. The effective components of ceramic tile adhesive have undergone chemical reaction, and adding water can only change the operational performance, which will lead to insufficient bonding strength; Tile adhesive should be stirred when used, and the use time should be controlled within 2 hours, and then discarded after drying.

Don't shave unevenly.

During the batch wall construction, it is necessary to ensure that the ceramic tile surface and wall surface are evenly scraped. Avoid hollowing the corners of tiles, long-term humid environment will lead to brick loss; At the same time, it is necessary to ensure that the tile glue is scraped evenly and completely. It is suggested to use a suitable toothed scraper, which should be selected according to the flatness of the base and the size of the tile, and should be kneaded in place when pasting, and the full pulp rate on the back should be checked.

Don't scrape too much glue at a time.

One-time scraping area is too large, which will cause the surface of ceramic tile adhesive to dry and solidify. In dry and windy outdoor weather, the scraping area of rubber cloth batch is too large, and the construction front layer is dry and solid, which will lead to brick falling; Therefore, the tooth scraper should be used to scrape the cement evenly on the working face, and the wall should be wetted in advance in the outdoor dry climate of about 1 m2 for each construction.

Do not paste directly.

When the wall is not firm, sandy, greasy or has too many defects, you can't directly stick tiles. Low base strength and oil pollution will affect the cohesive force of tile adhesive, leading to empty drums and bricks; Uneven walls and large defects will also cause the contact between tiles and walls to be out of place, which is prone to the problem of empty drum. Therefore, before the ceramic tile is pasted, the wall surface must be leveled to ensure that the wall surface is firm and smooth, and there are no factors that affect the cohesive force, such as oil pollution.
