When decorating a house with ceramic tiles, we will use many auxiliary tools, such as tile adhesive, which is the most common one. So, how to use tile adhesive? How to choose tile adhesive Do you know? Then follow Zhongtao Jun to find out more!
1. Three principles for purchasing ceramic tile adhesive
1. Look at the nature of the grassroots level
When it comes to the base layer, the two most common ones are concrete or brick. When choosing tile adhesive, you must understand the material of the facing material. In layman's terms, you must understand the characteristics of the base layer.
The base layer can be roughly divided into two categories: rigid base layer and flexible base layer. Concrete, brick masonry, masonry mortar and cement mortar belong to the rigid base layer, while cement fiber board, gypsum board, plywood and external wall insulation system belong to the flexible base layer. Grassroots level.
When choosing tile adhesive for rigid base layers, the tile adhesive will be selected more based on the performance of the main material and the location where it is used; while the tile adhesive used for flexible base layers generally requires a certain degree of flexibility, otherwise it will be used later. It is easy to cause hollowing and falling off due to deformation of the base layer.
2. Look at the substrate parameters
When choosing tile adhesive, you need to pay special attention to the water absorption and size of the tiles. The lower the water absorption rate of the tiles, the denser the tiles are. It is required to choose a tile adhesive with a better suction cup effect, that is, a high-level tile adhesive.
The larger the size of the ceramic tiles, the greater the load, which places higher requirements on the bonding strength of the ceramic tile adhesive.
When encountering some special substrates, we also need to consider the problems of efflorescence and color bleeding. For example, light-colored natural stone has more micropores, and tile adhesive is usually cement gray. When such gray tile adhesive is used to paste natural stone, it is prone to color bleeding, which reduces the appearance of the stone.
In order to avoid this situation, it is generally recommended to choose white tile adhesive as the tiling material.
3. Look at the usage area
Different usage scenarios, tiling areas, and matching tile adhesives have different performance requirements.
For example, the threshold stone area located at the junction of the kitchen and bathroom, hall, and room is the transition point between dry and wet areas. This area requires tile adhesive.In addition to adhesion, it is best to have waterproof and impermeable properties.
In this way, water vapor can be prevented from running into the living room and rooms and causing water vapor attack on the floor and wall paint.
In an environment like a bathroom that is immersed in water for a long time, it is best for the tile adhesive to have a certain degree of impermeability. Therefore, in order to improve the impermeability of ordinary tile adhesive, tile adhesive partner DL can be added to the tile adhesive, so that the durability of the tile adhesive is more guaranteed.
For parts such as flues and lightweight partition walls, they have a common feature that they often vibrate or the base layer is unstable, so it is necessary to choose a flexible tile adhesive. In this way, the deformation and vibration of the base wall are buffered by the flexible tile material, so that the tiles can be firmly adhered to the wall.
2. How to apply tile adhesive
1. Why can’t cement be added
The ceramic tile adhesive production process consists of five parts: calculation of proportions, weighing, mixing, processing, and ceramic tile adhesive packaging. Each link has an important impact on the performance of the ceramic tile adhesive product.
Tile adhesive itself contains an appropriate amount of cement components. It is scientifically formulated by adding various additives to enhance bonding strength and flexibility on the basis of cement.
Add cement mortar at will, which will change the proportion of production ingredients of ceramic tile collagen. In fact, there is no way to guarantee the quality. The tiles are prone to hollowing and peeling.
Because tile adhesive has good water retention, the drying time is slightly slower than that of cement. Blindly adding cement or adding water will cause the tile adhesive to lose its original effect.
2. Stir with an electric mixer
It is strictly prohibited to use shovels, wooden sticks, etc. for manual mixing. Because water is added by manual mixing, once dough appears, water must be added, which indirectly changes the ratio of the tile adhesive, causing the viscosity of the tile adhesive to decrease.
When using tile adhesive, it should be configured according to a strict water-cement ratio, and use an electric mixer to stir evenly for 3-5 minutes to form a uniform glue without lumps.
3. It should not be left for too long after stirring
After the tile adhesive is mixed, it generally needs to sit for about 5-10 minutes. The strength can be increased after a second stirring. Letting stand has two functions: one is to eliminate stirringSecond, the air brought in during the process allows the tile adhesive to fully mature, which is conducive to maximizing the adhesion force of the tile adhesive.
It is best to use up the mixed tile adhesive within 1-2 hours, otherwise it will lose its original sticking effect. Tile adhesive should be used as soon as you stir it. If it exceeds 2 hours, discard it and replace it with a new one.
Some masters will mix the tile adhesive left over the night before with water and tile adhesive powder the next morning. In fact, the active ingredients of the tile adhesive have already undergone a chemical reaction. Adding water only changes the operating performance, but will still cause problems. Resulting in insufficient bonding strength later.
4. The scraping area should not be too large at one time
In order to save trouble, some masters apply tile adhesive to a large area of the base layer, and then proceed with flow-type tiling. If the scraping area is too large, there will be no time for construction, causing the surface to dry and solidify, and re-laying bricks will cause bricks to fall off.
For correct construction, a toothed scraper should be used to evenly scrape the glue on the work surface. Each application should be within about 1㎡. The wall surface should be pre-moistened in dry outdoor weather.
5. Do not use tile glue to fill the gaps
Tile adhesive and grout are both building material auxiliary materials, but tile adhesive can only be used to stick to the back of tiles.
If you use tile glue to fill the joints, it will block the shrinkage joints of the floor tiles, causing the floor tiles to arch when heated, and they are easy to hollow and fall off. Therefore, special caulking or seaming agents must be used to fill the joints.
3. Correct construction steps of tile adhesive
Tile adhesive is an ideal material for tile pasting, and its construction method is thin sticking. The thin bonding method has higher requirements for the flatness of the base layer. The flatness of the base layer must be less than 3mm, and the verticality of the base layer must be less than 3mm.
1. Clean the base layer and keep it clean and strong
2. Hanging wires and arranging bricks
3. Configure glue
First add water to the mixing container, then pour in the tile glue and stir. Stir for about 5-10 minutes to form a uniform paste, then let it sit for 3-5 minutes until it matures, then stir a second time.
4. Use a serrated trowel to apply the glue to the base layer, comb it into strips, and paste the tiles in time
If the surface of the glue is dry, remove it and re-scrape the glue; for large-size tiles or tiles with deep grooves on the back, scrape and apply glue once before they can be pasted. The thickness of the glue can be controlled within 4mm.
If it is full ceramic tile, vitrified tile, stone and other low water absorption tiles, it is recommended to apply adhesive on the back of the tile. Inferior ceramic tiles have poor adhesiveness and will cause the ceramic tiles to fall off if they are not firmly adhered. In the end, the ceramic tiles will have to be reworked.
The above content is what Zhongtaojun shared with you How to use tile adhesive and How to buy tile adhesive. So, have you learned it? I said it in detail. You don’t want you to think you have learned it. I want me to think it, not what you think. Hahaha, that’s it for today’s content sharing. Zhongtao Jun will leave first!
