Do I need to redo the wall before scraping the wall after waterproofing?

After the wall is waterproofed, there is no need to do the wall solid before scraping the putty, clean up the dust on the surface, if the wall has peeling, it needs to be shoveled off to make it strong.

Wall solid, that is, interface agent, interface agent is the supporting material for wall base treatment in decoration projects. It is suitable for the interface treatment of concrete, aerated concrete and brick-concrete wall plastering putty or plastering before the base layer. It is suitable for artificial "wool making" on the wall base layer, that is, to make cement and brush, and is also suitable for pasting wall cloth, wallpaper and paper products.

The main function is to strengthen the bond between the two layers of materials, so that the putty can be better combined on the wall, and reduce the probability of quality problems such as hollowing and delamination.

How to use wall reinforcement correctly?

First, use a roller to apply the wall solid on the base surface, which should be left in a short time, and wait for the water to volatilize, the surface is sticky, slurry, close to the initial setting, and the subsequent material can be pressed into without slipping, and the putty can be plastered or draped putty.

The cement base is firm and the surface is smooth, and the putty is difficult to adhere, you can brush the interface agent to reinforce, but it is more recommended to chisel or pull the wall. Under normal circumstances, if you have made a putty base wall, please shovel off the putty layer and then make the wall solid.

Special attention should be paid to some decoration companies to enter the site to brush the wall solid, and then start to change the water and electricity slotting and other processes, which is unreasonable, the main role of the wall solid is to prevent powder and sand, after brushing the wall solid should be brushed putty as soon as possible to avoid other decoration dust secondary pollution of its surface.

If the cement mortar layer is of excellent quality, it does not need to be treated too much, and if the blank wall is very easy to sand and powder, it should be resolutely eradicated and redone.

The wall of the new house is a cement mortar wall, but it is not possible to ensure whether the cement quality is up to standard, and it is better to brush the wall solid.

It must be brushed to be more durable.

No, there are several reasons inherent in the wall, one, the good-looking wall is the wall, and the ground is the green space of the yellow wall. Second, it is a gelatinous stable dust. Third, one more project and one more project decoration company is good to collect money, and there are profits. That's why there is this piece.

It's best to brush it all over and take a stable one.

It is better to brush it with cement. This is easy to level and save materials.

You can brush the wall to scrape the putty, the effect is still relatively obvious, very good, the top scraping will be very beautiful, and it will not easily drop the color and foam is very perfect.

Brush the polyurethane wall, be sure to sprinkle coarse sandpaper on the material surface layer of the polyurethane wall, and then use 108 glue live cement brushing, and wait for the hardness of the wall to improve before the bottom glue scraping putty, if not in such an order of construction, the scraped putty will easily fall off.

This is also possible, but the wall surface of the polyurethane brush will be more slippery, and the putty will have to go through special treatment when scraping, which is more troublesome.

First, the role.

1. Prevent hollowing.

The wall solid has good permeability, can well infiltrate the surface of the wall base layer, and makes the base layer tight through gluing, improves the interface adhesion, improves the adhesion between the mortar or putty and the wall surface, and avoids hollowing. In fact, wall solidification is a kind of interface agent, which mainly plays the role of connecting the upper and lower levels, consolidating the substrate and allowing the coverage of other substances. If there is some powder on the interface, it is also possible to use it for the back cover.

However, if the ratio of cement mortar on the wall of the owner's home is appropriate, or the quality of the leveled gypsum is qualified, each step is in accordance with the construction standard, in fact, the wall can not be solidified.

2. Inspection of the wall treatment process Nowadays, more and more people use colored wall solids, and some people may feel that they will affect adhesion, but in fact, this is not the case, the reason why colored wall solids are used is mainly to facilitate management. For example, the wall solid yellow can detect whether the putty and wall paint are up to standard. But it's important to note that:

If the quality of the wall is not good, the interface is too smooth or the base layer is not clean, etc., there will be a phenomenon of wall delamination, so we should leave more whether the quality of the wall is passed.

Second, how to use.

Different uses, the use of wall solids is different. For example, the wall surface can be brushed, the wall solid and water can be mixed in a ratio of 1:1, and then the mixture and cement can be rolled in a ratio of 1:1, and the next step can be carried out after drying;

Many people may think that the role of the wall solid is waterproof and moisture-proof, in fact, the wall solid is to make the follow-up construction more convenient, increase the adhesion of the wall, brush the wall solid is equivalent to the wall base treatment and the next process between the addition of a layer of glue to improve the adhesion, and does not have the effect of waterproof and moisture-proof. The following is a detailed introduction to the role and use of the wall solid.

Before painting putty and latex paint, it is necessary to do some base treatment on the wall, and the use of wall solidification can reduce the appearance of sand or uneven particles when scraping putty in the follow-up, or hollowing and cracking after painting latex paint on the wall, so as to make the wall base more firm. Wall fixing can be used instead of transparent primer, and after drying, it can be further painted or wallpapered. However, painting the wall is not a substitute for waterproofing, and for damp and seepage walls, waterproofing treatment must be used to solve the root cause of water seepage.

Although it costs more money on the surface of brushing the wall, for the sandy wall, the use of the wall can reduce the probability of hollowing cracks, and if all of them are eradicated, it must be higher than the cost of brushing the wall. However, if the quality of the wall is very good, there is no powder and sand, and there is no need to brush a layer of wall solid, you can directly carry out follow-up operations.

Different uses, walls are inherently used in different ways. If the wall surface is brushed, the wall solid and water can be mixed with water 1 to 1, and then the mixture liquid and cement are mixed 1 to 1 and then rolled over, and the next step can be carried out after drying. If the wall is renovated, the original paint on the wall can be removed to the putty layer, the wall solid and water are mixed 1 to 1, painted on the wall, and the next step can be carried out after drying.

The role and use of wall solid is introduced here, before the construction is best to judge whether to use the wall solid according to the actual situation of the wall, if the quality of the wall is very poor, it is best to remove all the reprocessing, only rely on the wall solid can not be greatly improved.

Wall solid is an environmentally friendly product, the use of water-soluble resin, multi-functional additives refined water-based interface treatment agent, has a strong penetrating force, can fully penetrate and infiltrate the mortar base, effectively improve the bonding force between putty and the substrate, enhance the compactness of the base, improve the adhesion between the layer, so as to ensure the performance of the wall coating. From the perspective of color, there are mainly two types of transparent and colored walls on the market, and the colored walls are mostly yellow.

The effect of wall solidification is to the construction of the new house blank house or the renovation of the old wall, it is found that the surface of the wall is relatively loose, and the sand particles are seriously pulverized. The wall solid has excellent permeability, by brushing on the cement mortar layer, can effectively improve the mortar or putty and the surface of the wall bonding strength, the mortar layer itself is hard, the putty will have better adhesion, will be firmly attached to his surface, so as to prevent the phenomenon of hollowing.

What is Wall Solid? The function and use of wall solid and construction precautions.

What is Wall Solid?

Wall solid is a new type of material, this material can penetrate into the wall of cement mortar, firmly lock the cement wall, make the internal structure more stable, will not fall off the problem. Moreover, the mortar on the surface will be integrated, so that the surface and the internal structure can be effectively combined.

Generally speaking, it is a milky white liquid, which can improve the adhesion, and is more suitable for concrete or brick-concrete walls.

The scope of application and function of wall solidification.

1. Concrete surface: improve the adhesion of mortar and other materials on the smooth concrete surface, anti-aircraft drum;

2. Old walls and walls shoveled through the putty layer: it can prevent powder loss and improve adhesion;

3. Basement, door and window edges, kitchen, bathroom: reduce the influence of moisture on the decorative layer;

4. Sand aerated block wall: reduce the water absorption of the wall, improve the hydration process of cementitious materials, and improve the strength.

5. Batch scraping putty: add double fly powder and white cement and stir it to be constructed.

How to use wall fixing.

It can be brushed, roller applied, and sprayed.

Construction works: concrete surface can be directly painted, wall solid: 425 cement: sand 1::1.

Decoration engineering: the putty layer can be directly painted, when the viscosity is large, it can be diluted with water below 10, and when pasting tiles, it can be directly mixed with cement, and the wall is solid: cement 1:2.

1. Clean back covering: dust-free, oil-free and clean.

2. Glue: Glue this product by weight: ordinary cement mortar or adhesive = 1: Preparation, slowly pour the rubber powder into the glue, mix while pouring, stir well and form a porridge-like slurry without particles.

3. Gluing: Evenly brush the back of the vitrified brick and stone with a brush (it is advisable not to flow), generally brush 1 2 times, brush for about four hours and then paint the second time after it is completely dry, and the total thickness of the coating is about about about that.

4. Maintenance: Place in a cool and ventilated place, and put it into use only after it is completely dry.

When bonding wallcovering and wallpaper, if the viscosity is high, a small amount of water can be added to dilute it, and water should not be added to "make hair" with wall solids. Consumption: Theoretically, 1 kg of wall solid can be coated with 10 square meters (one time), and the actual amount is determined by a variety of factors in construction.

Precautions for wall solid construction.

The surface of the base layer should be solid and free of floating ash and oil stains.

After diluting the wall solid with 20% 30% water, apply it to the wall with a roller brush and apply it 1 or 2 times.

Wool making: Mix cement and wall fixing agent into a paste, and apply it to the base layer with a tool.

The construction temperature is above 5, and the unused glue should be sealed.

It is strictly forbidden to mix with other brands of adhesives.

How to tell if the wall is good or bad?

1. First of all, open the barrel to observe whether the wall is uniform, there should be no delamination, agglomeration, and pungent odor.

2. During the construction process, the wall should not produce a large number of pungent odors, and the smell should not remain for a long time after the construction is completed.

3. Wall solid is a kind of permeable curing agent, the firmness of the wall should be significantly improved after the construction is completed, and the wall solid penetrates the base but there should be no obvious film formation on the surface.

4. The wall should have water resistance, and the water will not fall off or fade after the construction is completed. If the glue type wall is thick and thick, there will be obvious film formation, and the coating film is not water-resistant, and there is a great risk of bleeding and peeling of the late tiling or batch scraping putty powder.

5. In addition to the above performance, it should also have bright colors. As for adding powder to the wall solids for better coverage, this product will significantly sacrifice the curing ability of the wall solids to the base layer.

Decoration Engineer Da Cui explained the construction site of the wall brushing, which can inhibit hollowing and falling off.

Wall solidification is a wall curing glue, which is a substitute for 108 glue and interface agent, and is a green, environmentally friendly, high-performance interface treatment material. The wall solid has excellent permeability, which can fully infiltrate the surface of the substrate, make the base layer dense, and improve the adhesion of the smooth interface. The wall solid is non-toxic, tasteless, and is a green and environmentally friendly product.

OK! It's best to use waterproof putty! So as not to tide up later!

If needed, even if you can't shovel it down, you can put it on the wall on some solid foundation in turn to fix the plaster putty.

Putty and wall lining have the same effect, so that the wall surface is smooth, the wall lining is better than putty, more expensive than putty, it is its replacement product wall solid and interface agent, is used to enhance the adhesion of wall paint.

The main function of wall solidification is to infiltrate the surface of the base material of the wall, make the base layer dense through gluing, improve the interface adhesion, improve the bonding strength of the mortar or putty and the surface of the wall, and prevent hollowing. It is cross-linked with the filler with strong shading to form a film, which can effectively solidify the loose particles in the inner and outer layers of concrete, promote the formation of a tightly hardened closed whole on the ground, and achieve its overall closed film-forming water-resistant and moisture-proof function. The main function of wall solidification is sand fixation, so it cannot replace waterproof coatings.

It is also possible, it is equivalent to an interface agent, which has strong permeability and increases adhesion. But it's better to use waterproof again, it's safer! Home improvement is not a waste of money.

The ground solid moisture-proof and waterproof can avoid the deformation of the wooden floor caused by moisture erosion, and can also avoid throwing ash from the cracks of the floor in the future. There is a little bit of a role; But if it's long-term, it's basically not good.

Wall solids and ground solids have a certain moisture-proof effect, but they are not professional waterproofing agents after all. In addition, it should be noted that the composition of the wall solid is acrylic, which will not react with the waterproof coating under normal circumstances. However, some wall solids are made of vinyl acetate emulsion, and the brush directly destroys the waterproofing effect on the waterproof layer.

Moisture-proof with ground and wall solids is only an auxiliary practice. The key areas should be treated with professional waterproof materials.

Wall solids and ground solids are a class of substances, and the wall solid is taken as an example to illustrate:

The wall is solid, with excellent permeability, can fully infiltrate the surface of the wall base material, make the base layer dense through gluing, improve the interface adhesion, improve the bonding strength of the mortar or putty and the wall surface, and prevent hollowing. It is suitable for the compacting treatment of brick-concrete wall plastering and batch scraping putty before the base layer. Wall solidification can improve the adhesion of smooth base layers, and is an alternative product of traditional building interface agents.

The conjunctiva it forms has a moisture-proof effect to a certain extent, but it is not a waterproof layer in the true sense.

Waterproof coating: The waterproof film formed by the curing of the waterproof coating has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, which can play a role in waterproofing, impermeability and protection. These characteristics are not available in wall and ground solids.

For true moisture and water resistance, it is recommended to use waterproof paint.
