Why don t you leave some wall putty?

The wall putty is not left for better ventilation, so that the wall will not bulge and is relatively flat.

There is no trace of the construction process of scraping putty.

Different base construction processes:

1. The process flow of scraping putty on concrete walls is as follows: base treatment - base repair - brushing caustic alkali aqueous solution - coating binder (juice slurry) - scraping big white putty - repairing and polishing - putty survival.

2. The process flow of scraping putty for concrete floor slabs and floor joints is as follows: base treatment - base repair - brushing caustic alkali aqueous solution - coating binder (juice slurry, spraying glue) - scraping white putty - repairing and grinding - putty survival.

3. The process flow of plastering cement mortar and scraping putty on the surface layer of paper mortar and paper glue is as follows: base treatment - coating binder (juice slurry) - scraping large white putty - repairing and grinding - putty survival.

Construction process: What skills are used to scrape putty quickly and flatly.

1. Grassroots treatment.

Cast-in-place concrete wall, due to many reasons such as floor slabs, materials, separators, etc., the flatness of the wall is poor, and there are often pores, honeycombs, hemp surfaces, yin and yang angles are not smooth and bulging, so it is required that the convex places are smoothed and smoothed, and the recesses should be filled and filled. For the precast concrete floor slab and slab joint base, it must be brushed by a special person with a wire brush to remove the floating sand particles, pimples, dust and other debris on the surface. For the cement mortar paper reinforcement ash surface layer, the surface base layer is required to be dry, solid and clean (no floating soil oil stain).

2. Grassroots repair.

After the concrete roof and slab joints are cleaned, the gypsum putty is filled and compacted with a steel scraper for larger defects such as honeycomb, and the horizontal wipe is scraped vertically (the top surface with a smooth surface can not be scraped). Gypsum putty mix ratio (weight ratio) is gypsum:emulsion:

Cellulose aqueous solution (concentration 5%) = 100:5-6:60.

Brush caustic soda aqueous solution: Brush twice with 5% caustic soda solution, if you use 10% concentration to brush once. It should be rinsed with water immediately with the brush, and then the next process should be carried out after drying.

3. Coat binder (juice slurry).

Before scraping putty, spray glue first, spraying must be uniform and consistent, and there must be no leakage where the glue mix ratio (weight ratio) is clear water: emulsion = 100:15-20.

Scrape the big white putty: scrape the putty with a steel scraper to scrape back and forth, pay attention to the upper and lower left and right connections, between the two scrapers to be clean, do not allow floating putty, scrape putty to prevent staining or mixing into sand and other debris. The mix ratio (weight ratio) of large white putty is large white powder:

Talc:cellulose solution (concentration 5%):emulsion = 60:

What technique to use to scrape putty quickly and flatly.

4. Repair and polish.

If there is a problem, use putty to repair and level the collapsed part, and after the putty is dry, polish, smooth and sweep with sandpaper.

5. Putty survives.

Scrape the big white putty twice, and then scrape it a second time after the first putty is dry, and it is generally required to survive at least twice. The surface is required not only to be smooth but also to have a uniform texture, otherwise it is easy to have inconsistent color shades and affect the decoration effect.

If you don't brush the wall, you won't necessarily scrape the putty directly.

If the base layer of the wall is relatively smooth, and the ratio of cement mortar is appropriate, then the putty will not fall off directly, and the wall can be solidified; If the wall is a little dusty or sandy, in this case, it is best to clean it and brush the wall 1 or 2 times is more appropriate.

Before the construction of the liquid surface of the wall, if the wall solid products can be used on the base layer of the wall, it can better play a bonding role and close the bond between the foundation wall and the putty. However, if the ratio of cement mortar is reasonable, and the wall base is flat and dry, the putty can be scraped directly without using the wall solid, and the putty will not fall off easily.

In order to solve this problem, we can add an appropriate amount of hydroxypropyl methyl chemical fiber when stirring putty powder, the dosage is about one ton of putty powder with 3-5kg chemical fiber, so the water retention and viscosity of the putty paste will be the best, and the probability of cracking will be much smaller after scraping on the wall. If the putty layer is cracked, if the putty powder is eliminated and brushed again, then it is fine, and the cracking of the wall is more serious, which will affect the expected effect of the visual impact of the design decoration.

There are also some tips to reduce the probability of wall putty wall plastering cracking: when scraping putty powder in batches, it should not be too thick each time, and it should be covered thinly many times, because if the batch is scraped too thick, it will crack as soon as it dries. After scraping the putty powder once, you must wait for the putty powder to be abundant before you can scrape it again, otherwise it will be easy to crack.

If the temperature is very dry, or if the air circulation is very good, close the doors and windows to prevent cracking due to drying too quickly. Putty powder is a professional term in decoration. Personally, I think that the greasy in the meaning of putty powder actually refers to the greasy feeling of greasy, which also shows that putty powder is like a mud-like object with greasy sensibility in terms of surface condition.

If you scratch putty in your newly renovated house, in fact, as we all know, the main role of putty powder is actually to find a quiet treatment for the lowest layer of the wall. Because if the wall before scraping putty powder is not a wall stucco wall, if it is not a concrete wall, a thick and thick filler must be used to scrape and fill. The original plaster used to be used is the same as the current putty powder, and the bottom floor leveling can also lay a basic foundation for the next layer of decorative construction.

After the putty cracks, it is generally the wall mixed mortar that cracks, and if it is cracked, the cracked mixed mortar must be removed, and the mixed mortar must be brushed again, and the putty will be brushed after drying.

After the putty cracks, it is generally the wall mixed mortar cracking, if you have to remove the cracked mixed mortar, brush the mixed mortar again, and then brush the greasy after drying, before the house decoration to scrape the putty powder, carefully and carefully the wall, ceiling gypsum board and gypsum board joints, walls and shells, door frame joints, etc., to see if the wall has cracks, wall cracks, etc. The home improvement ceiling production process is done well, and cracking will be avoided as much as possible in the future. First use quickgypsum ash to scrape the gap between the joints, then hang the glass fiber mesh cloth, scrape the putty ash three times, grind it after drying, and paint the wall twice, it's OK, if the putty layer is cracked, if the putty powder is eliminated and brushed again, then it's OK, the wall cracking is more serious and will affect the expected effect of the visual impact of the design decoration.

Therefore, the use of putty powder can also do a certain amount of protection for the wall, so that the service life of the wall is improved.

We can add an appropriate amount of hydroxypropyl methyl chemical fiber when stirring putty powder, the dosage is about one ton of putty powder with 3-5kg of chemical fiber, then the water retention and viscosity of the putty paste will be the best, after scraping on the wall to dry, the probability of cracking will be much smaller.

Putty powder can be used, generally need to be scraped three times, the grip of putty powder is larger, after scraping three times, you can be a good house, putty powder cracks on the wall, and can make the wall very smooth.

You can hang a net on the wall before brushing putty powder, so that the problem can be effectively solved and will not crack.

Reasons why putty is not scraped at the root of the wall: putty is prone to cracks, peeling, and falling off. The cracking, peeling, and peeling of putty are mainly caused by the poor bonding between putty and the base layer.

If the base layer is not cleaned up or the treatment method is improper, the template release agent, oil co, inorganic acid and organic acid on the base layer are not completely removed, the caustic alkali aqueous solution (used to remove the wall oil stain) is not brushed, the binder is not applied or the putty formula emulsion is improperly mixed, the result will reduce the bonding strength of the putty and the base layer.

Process introduction. The wall not only needs to be scraped putty but also plaster, but the plaster is scraped before the putty, because scraping plaster can play a role in sound insulation, and can also adjust the temperature in the room and play a role in heat preservation. And if you only scrape putty, the wall will be very rough, and the material will be relatively lost, and the overall scraped wall will be uneven, which will affect the overall aesthetics.

Therefore, putty and gypsum are both needed, if the wall still has potholes, gypsum is needed to fill it, so that the wall surface is flat, and putty has no way to fill these potholes. Even if you renovate the wall, you need to remove the wall skin and then fill it with plaster, and then use putty, so that the surface can be smooth and flat.

No. The new cement wall cannot be scraped putty without 5 days, because the cement wall may not be completely dry after about 5 days. Under normal circumstances, the cement wall can only be scraped after it is completely dry, and the drying time of the cement wall is usually about 28 days, but the specific drying time should also be determined according to the ambient temperature.

Related information: 1. Before painting the wall with cement, the wall must be cleaned. And use sandpaper and brushes to clean the wall, and dispose of the floating ash and dust on the wall.

Then after grinding to a uniform condition, wait until it is completely dry, and then scrape the putty. 2. When scraping putty, be sure to test the flatness of the wall. When scraping putty again, scrape putty twice on the wall, so that the wall can be leveled and the background color of the wall can be covered.

If the flatness of the wall is not particularly good, it is necessary to scrape putty several times in some uneven places. If the flatness is particularly poor or there is an inclination, it is necessary to scrape the leveling plaster first and then scrape the putty. 3. And when brushing the topcoat, you should paint the wall twice, wait for about 2 or 4 hours between each time, and wait for it to dry before brushing the second topcoat.

Under normal circumstances, it takes about 1 to 2 days to dry after brushing. And before drying, we must make sure that the wall is not damaged, otherwise the overall effect will not meet the corresponding standards. Moreover, the surviving walls should be strong and flat, and there should be no cracks between them, and the color should be treated evenly.

In fact, there are two main reasons for the putty scraping on the wall: one is that the wall is too smooth, and the other is that there is an isolation layer on the wall. Both of these conditions can make it difficult to scrape putty.

The following will answer the treatment measures before scraping putty on the wall for these two situations.

Treatment measure 1: Spraying or brushing.

At this time, a high-strength cement slurry is used to spray or pat the original surface. The purpose is to use the cement slurry to combine with the original smooth wall surface to increase the bonding stool strength of the cement surface base.

Processing steps: First, we first purchase the finished hair spraying material, or use cement to add a jujube Heng Suiding glue to stir into a hair spraying material.

2. Use a hair-spraying machine to spray wool on the wall. Or you can use a broom to beat it.

Third, the final formation of the surface of the hairspray burr. In this way, the burr strength of the spray is qualified.

The wall putty is applied before painting, and the purpose is to fill the cracks and uneven surfaces on the original wall, so as to ensure the flatness and beauty of the final coating results. However, if the wall putty is not well brushed, it will affect the final painting effect. How to solve the problem that wall putty is not easy to brush?

1. Check whether the wall putty is fully dry.

If the wall putty is not completely dry and the coating begins, it will cause the wall to absorb too much water, and the phenomenon of chalking or cracking will appear. Therefore, before brushing the wall putty, make sure that the putty has dried.

2. Adjust the consistency of the wall putty.

If the wall putty is too sticky, it will not be easy to push away. And if it is too thin, there will be potholes. Therefore, it is necessary to pay attention to controlling the consistency of wall putty. If the putty on hand is too thick, consider adding some water to it to dilute it before applying it.

3. Choose the right tool.

The application of wall putty requires the use of a special putty brush or roller. If you use an unsuitable tool, it can cause the brush to leave visible scratches on the wall. Therefore, before painting wall putty, it is necessary to choose the right tool.

4. Master the correct painting method.

When painting wall putty, we should pay attention to the method, so that the brush is evenly and evenly painted, and sometimes it is necessary to properly cross paint to achieve better results. If the builder brushes too much area when brushing the wall putty, the putty will be difficult to control if the putty dries for too long, which will affect the painting effect.

In short, before painting the putty on the wall, you must first check whether the putty is dry, then adjust the consistency, choose the right tool, and grasp the correct painting method. These methods can effectively solve the problem of wall putty is not easy to brush. If none of the above methods work, you can consult a professional construction personnel for better guidance.
