Is it better to use pure cement for wall tiles or to add sand? What s the difference?

First of all, in terms of cost, cement is better than sand.

It is much more expensive, so adding sand and gravel will reduce some manufacturing costs.

Secondly, the thickness of pure cement is limited to less than 5 mm, and if it is too thick, it will flow. In addition, if the cement slurry is too thin, it is easy to lose water during curing and the strength is insufficient. The cost of pure cement slurry is higher, which is why pure cement slurry is not commonly used, and it can also be used with a small amount of quality assurance.

In addition, cement has dry shrinkage properties. Sand and gravel is an aggregate, which can not only improve the strength, but also inhibit the dry shrinkage and deformation of cement. When using pure cement, a big change in temperature and humidity in the following environment will quickly collapse, which is what we call a hollow drum.

Fall down! This is because it is said that wall tiles are not the same as floor tiles.

Different. Wall tiles are generally glazed with clay, which is not as strong or dense as floor tiles, with a relatively high water absorption rate and high adhesion to wall tiles. <>

It is not recommended to use pure cement for wall tiles, as they are much more demanding than floor tiles, and many decorators use pure cement to prevent trouble. The decorator told me that using pure cement will cause the wall to expand and crack, and pure cement paste is not as good as cement mortar.

Stickers are effective. If there is no thickness requirement, you should ask the home improvement master to use cement mortar to tile. <>

In general, it is better to use pure cement or add sand to the tiles on the wall, both of which have their own advantages, but it is better to add sand to the wall, because it can increase the adhesion of the tiles. And the addition of sand can also greatly reduce the cost, reduce the cost and improve the quality, that is naturally the best choice. But I have also seen the use of pure cement, tiles, and the effect is still very good, which is to make a choice in the quality of the tile, be sure to choose those tiles with strong adhesion, and better quality tiles, because there are some tiles after the completion of the paving Its water absorption is not strong, so it will cause it to be hollow, and it will fall off after a long time.

If it falls off, it will be very serious, and if it hits us, it will be a very big thing.

You need to choose cement and sand first, because when you use pure cement to pave tiles, it will absorb the surrounding moisture when it hardens, which will become tight, causing the tiles to fall off. Cement sand will not appear this problem, it can ensure that the tile paste is stable, the actual operation should be in accordance with the order from bottom to top, from left to right, and the tile should be soaked in water for more than half an hour before construction, so as to ensure that the small holes of the tile fully absorb water, avoid the absorption of water in the cement after paving, resulting in the situation of falling off.

The application of cement cement mortar to the wall tiles is the most traditional way to apply tiles, which is the wet hanging method we often hear. In the case of floor tiles, cement and sand are mixed evenly according to a certain proportion to paste the floor tiles。Cement cement mortar can often paste the tiles, in fact, it relies on the tensile force of a device generated between the cement cement mortar and the wall tiles after setting.

One of the most important tensile forces is the tensile force caused by the mutual penetration between the cement mortar and the porosity of the back of the floor tiles. The proper noun of technical expertise is called mechanical equipment embedding cooperation. The stronger the mechanical equipment, the stronger the tile will be.

Nowadays, this kind of practice is getting lower and lower, but cement cement mortar is the most traditional auxiliary method, and the ratio of cement and sand is generally 1:2;The greater the cement, the stronger the tensile strength, and this kind of auxiliary wall tile is generally called wet auxiliary method. This kind of wet auxiliary method is mainly based on a kind of natural door handle produced by cement cement mortar and wall tiles after condensation; This kind of tensile force is mainly based on the interaction between the eyeball on the opposite side of the wall tile and the cement cement mortar, but when using this kind of auxiliary method, we must remember that the market share of cement is too high, otherwise the cement will be established after the condensation of course, the door handle will crack the wall tiles.

Many customers have cracked after the end of the auxiliary installation of the wall tiles in the bathroom, and the customers want to blame the wall tiles of the store for product quality problems, which is caused by the wrong proportion of mortar in the work.

There are many kinds of pure cement, masonry batch putty cement, floor leveling cement, masonry ground leveling two-in-one cement, composite Portland cement, six or nine quick-setting cement, interior decoration can not use pure cement to pave wall tiles, with masonry batch putty cement to pave wall tiles, the initial compressive strength is not very good, there is almost no compressive strength, if the masonry batch putty pure cement is used to pave the wall tiles, there will be product quality problems, because there is no actual effect of final setting, Therefore, it is impossible to condense at all, and there is no doubt that the cement paved wall tiles without condensation will fall.

Masonry batch putty cement is more common, cohesiveness and water retention performance is better, the key is made of dynamic thermoplastic resin, coal ash and hydrated lime powder putty powder mixture, the main push is used to masonry scrape the wall, the project temporary settlement of simple mobile houses, can also be used for large buildings to do backfill, because the masonry cement is affordable, the sales volume of the decoration industry has been good, the general self-built house wall plastering wall is a good choice, the biggest advantage of masonry cement, the price is affordable,The construction of the project is simple and convenient, and there are some project construction community owners who use masonry cement to make cement pavement, save decoration costs, and the cost is lower.

cement mortar; Cement mortar is better, the service life will be longer, and it is also very convenient when cleaning.

Cement mortar will be stronger, pure cement is not strong, and the cost is also high.

Houses like cement mortar have good breathable building strength, and are good building materials that can play a waterproof role.

There is no need for cement and sand anymore. Tile adhesive is suitable for indoor and outdoor concrete or cement mortar substrates, tiles, marble, granite, mosaic paste.

Features:

The construction is simple, there is no need to soak the brick wet wall, and the work efficiency is high.

The adhesive layer is thin, the adhesion is strong, the material is saved, and it is uniform, and the hollowing is avoided.

Green, safe and non-toxic.

Base Requirements:The surface of the substrate is strong, dry, clean, free of oil, concrete curing agents and other loose materials.

Construction method

Mixing ratio: water:powder = 1:4 (kg).

Pour water into the container, then add the tile adhesive in proportion, stir it into a homogeneous, grainless paste with electric stirring, let it stand for 5 minutes and stir for 1-2 minutes.

Use a toothed scraper to apply the tile glue to the base surface. Make it evenly distributed, and form a strip of teeth, apply about 1 at a time, and then knead the tile on it.

If the groove on the back of the tile is deep, in addition to applying tile adhesive on the working surface, the adhesive should also be applied on the back of the tile.

Precautions

This product is suitable for construction in the environment of 5 -40, and the vertical and flatness of the base surface should be confirmed before construction.

It is best to use up the tile adhesive that has been stirred with water within 2 hours, and do not mix and mix the tile adhesive that has been dried and solidified, and only after 24 hours after the construction is completed, you can step into or fill the joint.

Chimeric dry paving method: first set up grooves at the four corners of the tile, then fix the chimeric piece on the ground, install the two butt, and finally paste the adhesive on the back of the tile, which can prevent the tile from sliding everywhere and will be safer. Our home is decorated with floor tiles.

At present, almost all of the floor tiles in our country will use cement and sand. There are actually three ways to use cement and sand to lay floor tiles: the first is the most traditional wet paving method.

The second is the more popular dry paving method. The third is to use adhesives to lay floor tiles.

Due to the new ceramic tile auxiliary materials on the market, the use of cement and sand for pasting ceramic tiles is very few, and now the decoration of pasting tiles, the use of ceramic tile back glue, tile adhesive, new decorative materials. Due to the relatively short time to market of the two materials, the principle of tile paving is similar to that of a keel for paving floors, a steel skeleton with leveling screws. After the skeleton is ready, the foaming agent is applied to the skeleton.

Paste the tiles. The use of tile paving racks can be done without cement mortar.

Save on shipping, upstairs fees. Now the freight and upstairs fee of cement and sand are a high cost.

<> by using marble glue on the back of the tile.

Paste as a structural support, the construction process of dry hanging is very fast, the effect of the later stage is also very good, and it is very strong, it is rare to appear like a wet shop with a hollow.

or the case of a drop. But the cost of dry hanging will be higher, and then dry hanging needs steel structure priming will increase the share of space tile adhesive, 20-25 kg a bag, directly mixed with water, with a toothed spatula, a bag can be paved 3-4 square meters, the adhesion is 2-3 times that of cement, the bonding thickness is only 3-6 mm, no waste of space, the ratio of not using cement yellow sand began to slowly improve, tile adhesive is the main alternative. And now many users like floor tiles on the wall, whether it is a background wall.

Or the bathroom, they like to use the moisture content.

The lower glazed bricks are done, and they can be renovated after a long time, and the rich play time.

You can use the chimeric dry paving method: first set up the grooves at the four corners of the tile, then fix the chimeric piece on the ground, install the two butt, and finally paste the adhesive on the back of the tile, which can prevent the tile from sliding everywhere, which will be safer and more convenient.

The principle of tile paving is similar to that of a keel for paving floors, a steel skeleton with leveling screws. After the skeleton is ready, add foaming agent to the skeleton and paste the tiles. The use of tile paving racks can be done without cement mortar, saving freight and upstairs fees.

Now the freight and upstairs fee of cement and sand are a high cost. As long as the floor is slightly higher, the upstairs fee often exceeds the ** of sand. Last year, a six-story multi-story house cost 8,000 yuan for bricks and cement sand alone.

Another benefit of the tile paving hanger is that it can be installed quickly and the construction period is shortened. Some people may be worried about the strength and whether it is easy to step on, but in fact, it can bear the weight of a car after being installed flat. If it is a metal weight, the tile will cause damage regardless of the method of laying the tile, and it is relatively easy to replace it with a tile paving rack.

Do not use cement and sand to lay tiles, you can pave them overhead, that is, install the keel on the ground, lay the tiles on the keel, and then use adhesive to lay the tiles, directly on the ground to wipe the adhesive, and pave the tiles.

At this time, you need to use super glue, apply a little glue under the tile, and then cover the tile.

In addition to cement and sand, you can also use super glue or glass glue, first to make a skeleton, and then lay the tiles and penetrate the glass glue into the gaps between the tiles.

When pasting wall tiles, many people also want to use only cement, so is it okay to stick wall tiles with pure cement without sand? It's also a very important question.

It is also possible to use only cement for wall tiling, but it is also very demanding for construction, and the cost of materials has increased. This aspect is something that needs to be known.

If it is considered thinner than the thickness of the package, it can be applied directly to ordinary cement slurry.

If the thickness of the packaging material is not required, it is recommended to use cement mortar for economical decoration.

The first trowel must be carried out after the uneven wall surface is cleaned after the uneven wall cutting and repair of the wall surface with a layer of cement mortar sold with a layer of cement mortar at least 15mm thick, before pasting, the base layer is cleaned to produce a thick, rough and smooth substrate.

Both verticals are important: the internal tile adhesive and the elastic line of each wall panel, the standardization for each size, the uniformity of the internal rules of the wall surface in size, the measured pseudo-tile adhesive layer usually has a thickness of 15-17 mm. Pure cement without sand to stick the wall bricks on both sides of the wall tiles, the length is 1mm, and then used as the standard thread-by-line thread paste bricks.

Elastic horizon lines and surface planarization lines: These are key measures to ensure that the plywood is horizontal and vertical, as well as the surface is flat.

Use the level to draw horizontal lines. The surface roughness of each tile wall, which is located on both sides of the hook layer of the thin steel plate tensioned with right-angle fracture paste (white line), is tension flat, white striped surface line: pure cement without sand pasted to the wall bricks The flatness of each row of bricks helps the bricks to control the height of each row.

Tile product selection to understand.

Living room if the size of the wall is generally a living area is based on the size of the indoor space is relatively small, to determine the size of the wall, try to choose a few specifications, such as less than 30 square meters of living room area, we can consider 600 * If the 600 mm specification requires the wall, larger than the 40 square meter living room area, it is recommended to choose the specifications of the wall 800 - 800 mm, the wall area is 1000 * thousand mm can be considered.

Kitchen & BathroomSince the kitchen and bathroom space is relatively small, we usually choose smaller tile wall tiles, such as 300*300mm wall tiles. When building an open kitchen, you can choose a larger tile: 600*600mm.

If your bathroom area is large, you can also choose 600*600mm tiles.

When tiling the pure cement wall, it is also necessary to understand the construction.
