Thin paste method construction process, thin paste method and the advantages and disadvantages of traditional methods of comparison

I. Comparison of the advantages and disadvantages of the thin paste method and traditional methods

Thin paste method process

▲Unit adhesive dosage is small, the coating is thin, only 3kg/m.

▲Construction speed is fast, up to 20m/manual day.

▲Unlimited grass-roots level, no need to use water to soak the bricks, saving labor and materials, environmental protection.

▲Strong bond, low comprehensive cost, construction quality is guaranteed.

Traditional thick coating wet bonding process

▲Unit adhesive dosage is large, the coating is thick, up to 10kg/m or more.

▲Construction speed is slow, only 6-8m/labor day.

▲The grass-roots level is limited, and it is necessary to dip bricks in the wet wall, which is labor-intensive, water-intensive, and pollutes the environment.

▲The bonding force is poor, easy to appear hollow drums, alkali problems.

Two, thin paste method and the traditional construction process way to compare

Thin paste method construction process

1, directly on the wall slurry scraping slurry with a special toothed tile scraper.

2, tile kneading.

Traditional construction process

1, soak the brick, mix the material on-site tile leveling.

2, wall sprinkling brick back to wipe slurry.

Three, the use of high-quality tile adhesives and experienced construction team

Quality tile adhesives, that is, a pre-mixed polymer mortar materials, cement, aggregate and polymer modified materials **** with the composition of the dry powder in the factory in strict accordance with the ratio of the mixing product, it is a more stable quality, the scene only need to add water mixing on the use of the product The stability of the product is easy to be controlled and convenient to use. At present, there are many kinds of domestic and imported products, and it is very important to select the products with mature technology and good brand.

With good materials is not enough, the construction of the link is also very important, choose to understand the construction of thin paste method of construction team to operate, is to ensure that the quality of the project is the key. At present, some manufacturers have begun for such construction team certification work, choose to certify the construction team is a good way to ensure the quality of construction.

Four, thin paste process

1, advantages and disadvantages

Advantages:

①construction efficiency, low requirements, saving space and materials

② quality relative to the thicker paste better, low drum rate, strong firmness.

Disadvantages:

①Relatively speaking, the cost is relatively high, mainly labor costs

②High requirements for the grass-roots level, if the wall is not flat, paste out the effect will be extremely poor

③Limited to the wall

2, grass-roots level:

①Cement layer should be strong, no hollow drums, no cracks, no holes.

② grass-roots level, no dirt, grease, dust, unevenness, sand (error in 3mm)

③ construction temperature 5 ℃ ~ 35 ℃

3, adhesive treatment:

① tap water into the mixing bucket, and then paste the agent to join one by one, the mixing ratio of water 1: agent 4.

②, let stand for 5 minutes! After 5 minutes, the second mixing, about 1~3 minutes can be.

Five, paste method

1, the base coating method:

Appropriate amount of bonding coated in the construction of the bottom surface, with a spatula along the straight line direction of the comb into a stripe, the tiles will be coated with adhesive coated grass-roots level pressed.

First smear a thin adhesive on the wall, the thickness of the adhesive is 3mm, and then use the spatula to scrape the cement mortar just smeared into a tooth mark

2, back coating method:

Back coating method needs to be removed from the back of the tile of dust and debris, and then a small amount of bonding agent mastic, scrape the back of the tiles full of scraping with the spatula, using a serrated knife scrape out the streaks, will be smeared with bonding agent mastic The tiles will be pasted onto the wall as required.

3, large size combination method:

①Apply the appropriate amount of adhesive on the construction of the bottom surface, along the straight line direction of combing out the striped texture.

②A small amount of bonding agent slurry, with a spatula hard full scrape on the back of the tiles.

③Paste to the proper position, the tiles have been pasted 15 minutes after the tiles can not be moved.

④If you need to adjust, you can must quickly remove the adhesive on the back of the tile and the construction surface, and reapply adhesive.

Six, notes:

1, after mixing the adhesive, must be used up within 2 hours. And stir every half an hour to keep the binder alive and not to be used after curing.

2, the construction of 4~6 hours to set, before the surface of the subsequent construction, such as hook joints.

3, tile paving also pay attention to the direction, otherwise it will affect the beauty of the pavement.
