Can exterior wall waterproofing putty powder be used for interior walls 5

The putty used on the exterior wall is also suitable for indoor use, because the quality of the exterior wall putty is water-resistant than that used indoors, and the putty generally has the distinction of interior wall putty and exterior wall greasy, but the products of the exterior wall and the interior wall are not the same, and the exterior wall must be better than the interior wall, if the time is still sufficient, you can try to do a simple test first.

Exterior wall putty has a certain waterproofness, not afraid of rain, it belongs to oily putty, both internal and external walls can be used. Whereas, interior wall putty does not have waterproof properties and cannot be used for exterior walls.

The difference between exterior wall putty powder and interior wall putty powder.

1. The main difference between interior wall putty and exterior wall putty is that the ingredients are different.

Second, the interior wall putty is made of double fly powder (big white powder) as the main raw material, so its water resistance and hardness are relatively poor.

3. Exterior wall putty is made of white cement as the main raw material, so its water resistance and hardness are much stronger.

Fourth, there is not much difference between the thickness (particles) of interior wall putty and exterior wall putty, and it is difficult to distinguish it only by looking at it and touching it.

Fifth, there is not much difference between interior wall putty and exterior wall putty in terms of environmental protection, because the environmental performance of the raw materials used is basically the same.

6. Exterior wall putty is mainly of high strength, and it is not as operable as interior wall putty when scraping on the wall, and it is not easy to polish after drying.

7. The main raw material of interior wall putty is white powder, and the main raw material of exterior wall putty is white cement, and the difference between white powder and white cement is too big.

8. No matter how the large white powder is formed, the strength is very low after drying, and the traces can be scraped with the nails, and it will soften again after encountering water.

9. The strength of white cement is very high after hydration and solidification, and even a small hammer can not knock out traces, and it will not be hydrated or softened again after encountering water.

10. Performance: The putty on the interior wall is delicate, but it is hollow and falls off when it encounters water, and the putty on the exterior wall is rough but waterproof.

It is best not to, the flexibility of the exterior wall putty powder is insufficient, it is easy to crack when used for interior walls, and the exterior wall putty powder is relatively coarse, and the decoration effect of interior wall use is relatively poor. It is recommended to use Dajiang putty powder produced in Fuzhou, standard type.

From the construction point of view, it is completely possible, but the cost is relatively high, the decorative effect of the paint is not as good as the indoor putty, and the environmental protection is not as good as the indoor putty, if you use it indoors, you can buy water-resistant putty, and the high-grade water-resistant putty of Jinyu is very cheap and the quality is also very good, or buy Jinyu full-effect water-resistant putty, or the easy scraping flat 800 of Meichao

Won't your costs increase? Don't you want to use the interior wall and go directly to the exterior wall? If that's the case, you'll have a bumpy wall! The interior wall is leveled and the exterior wall is lightened, which is very effective.

Summary. Dear, it's okay, it's just more wasteful. Try not to use exterior wall putty to brush the interior wall, because the exterior wall putty will be much more expensive than the interior wall, which also leads to an increase in decoration costs, and the decorative effect is relatively rough after construction, not as delicate as the interior wall putty, which will affect the effect of painting in the later stage.

Dear, it's okay, it's just more wasteful. Try not to use the orange of the exterior wall greasy bend pin to brush the interior wall, because the exterior wall putty buried in the group will be much more expensive than the interior wall, which also leads to an increase in the cost of decoration, and the effect of the decorative bucket calendar after construction is also relatively rough, not as delicate as the interior wall putty, which will affect the effect of painting in the later stage.

The most significant difference between these two types of putty is that the oak brother is in the ingredients, for the exterior wall putty, it is mainly prepared with white cement, while the interior wall putty powder is mainly made of double fly powder. The hardness of the outer wall is greasy and the bush will be stronger than the inner wall putty. At the same time, they are also different in terms of water resistance, exterior wall putty has good water resistance, while interior wall putty is inferior to a cherry, this is because exterior wall putty powder is mainly used on the exterior wall, and the environment of the interior wall putty is different, so the water resistance and hardness are required to be good.

Summary. Exterior wall putty powder can be used on the interior wall, but try not to use exterior wall putty to brush the interior wall, because the exterior wall putty will be much more expensive than the interior wall, which will also lead to an increase in decoration costs, and the decoration effect is also relatively rough after construction.

Exterior wall putty powder can be used on the interior wall, but try not to use exterior wall putty to brush the interior wall, because the price of exterior wall putty will be much more expensive than that of the interior wall.

The water resistance and hardness of exterior wall putty powder are much stronger than that of interior wall putty powder, as for environmental performance, thickness, and fineness, there is not much difference between the two. The color of the exterior wall putty powder will not be particularly white, which will also affect the high effect of scraping out the wall surface.

OK. However, it is not recommended to use it in this way.

Because the exterior wall putty powder does not meet the environmental protection standards of building materials, because the exterior wall must use glue in order to achieve water resistance, excessive glue will produce formaldehyde and other pollutants. If it is used as interior wall putty powder, it will affect human health.

Exterior wall powder is made of kaolin as the base material, with fibrous starch materials and other additives finely processed. Its outstanding characteristics are high bonding strength, alkali resistance, good construction performance, as a surface leveling material for outdoor buildings, to avoid the occurrence of peeling, blistering, chalking and falling off.

It cannot be used for repairing large cracks and potholes on the ground, ceiling and wall, and the follow-up construction of this product can only be carried out after being treated with anti-cracking substrate with different functions, otherwise it is easy to crack.

The putty used on the exterior wall is also suitable for indoor use, because the quality of the exterior wall putty is water-resistant than that used indoors, and the putty generally has the distinction of interior wall putty and exterior wall greasy, but the products of the exterior wall and the interior wall are not the same, and the exterior wall must be better than the interior wall, if the time is still sufficient, you can try to do a simple test first.

1.Exterior wall putty powder can be used for interior walls.

2.But try not to use exterior putty to brush the interior wall, because the exterior wall putty** will be much more expensive than the interior wall, which will also lead to an increase in decoration costs.

3.Moreover, the decorative effect is also relatively rough after construction, and it is not as delicate as the interior wall putty, which will affect the effect of painting in the later stage.

Ask Lafarge caulking paste primer, and then batch interior wall putty, will there be anti-alkali phenomenon, and if so, is there any way to remove it.

Answer 1: If it is only the phenomenon of alkali return on the surface, it is mainly caused by the poor compactness of the material inside the material and the easy absorption of water. The treatment method is surface cleaning, combined with the surface pollution and acid rain reaction of the material during use, and a certain proportion of oxalic acid solution is used for regular cleaning.

This is a pretty good way to deal with it.

Question: What is the cause of the anti-alkali phenomenon in the general interior wall?

The general reason for answering the alkali return is that the solid particles that cannot be firmly coated after the solidification of the base layer, middle layer and surface layer are soaked out of the surface by external force and produced after drying. Cement alkali return may have certain reasons related to cement quality, sand, water, air, temperature, and humidity.

There are many reasons for the alkali resistance of interior walls.

The material of the interior walls can be caused by.

1.Putty does have interior wall putty and exterior wall putty, but the products of exterior wall and interior wall are not the same, and it is not that the exterior wall is necessarily better than the interior wall.

2.From the implementation standard, the crack resistance and weather resistance of the exterior wall putty are very high, and the water resistance is certain, but the exterior wall putty does not need to do the environmental protection testing of indoor materials, so the exterior wall putty is generally through the blending of glue (this glue is much better than the performance of the same, and it is much more expensive) to achieve crack resistance and weather resistance, and the environmental protection of the glue used is relatively poor, if it has to be used in the interior wall, it is easy to cause formaldehyde and VOC to exceed the standard.

3.Another important point is that the common exterior wall putty on the market is almost all fake, in other words, it is inferior exterior wall putty that does not meet the standard of exterior wall putty but pretends to be exterior wall putty. Most of this kind of putty is not two-component, that is, there is no need to blend glue, although the risk of environmental protection is reduced, but the performance is very doubtful, and it is difficult to say whether it can really meet the standard of indoor water-resistant putty.

4.If the time is still sufficient (more than 7 days), it is recommended to do a simple test first: to a little sample of exterior wall putty, after stirring, evenly wipe it on the wall or cement board, after 7 days, splash water to moisten the putty, rub it with your hands to see if it becomes white pulp, if so, it is not a fine leveling with good water resistance, if not, then you can use it (provided that it cannot be mixed with glue).

From the "Red Book of Wall Decoration".

Exterior wall putty powder can be used as interior wall putty powder, but it is not recommended to use it this way.

Reason: Exterior wall putty powder requires high requirements such as earthquake resistance, flexibility, weather resistance, and water resistance, but exterior wall putty powder does not need the environmental protection standards of building materials, because the exterior wall must use glue in order to achieve weather resistance and super water resistance, although this glue is very environmentally friendly, but it becomes unenvironmentally friendly if it is added more, so it is not recommended to use the exterior wall as interior wall putty powder, which will produce formaldehyde and other pollutants.

Knowledge development: the difference between exterior wall putty powder and interior wall putty powder.

1.The composition is different, the exterior wall putty powder is mainly white cement, and the interior wall putty powder is mainly old powder and talcum powder in China.

2.The water resistance is different, and the exterior wall putty powder has very good water resistance after drying, mainly because the cement content is different or the rubber powder content is different.

3.The exterior wall putty powder cement content is high, so it is generally more alkaline. The interior wall putty powder is relatively delicate to meet the characteristics of interior wall construction; The grinding performance is also better than exterior wall putty powder.

4.Exterior wall putty powder is stronger; The construction is relatively difficult. Generally, it is not mixed and cannot be used on interior walls.

Exterior putty can be used indoors, but it is generally not recommended for interior use. On the one hand, the reason is that exterior wall putty is much more expensive than interior wall putty, and if the exterior wall putty is used internally, the cost will increase; On the other hand, the exterior wall putty is more coarse than the interior wall, and the interior wall putty is not as white and delicate as the interior wall putty, and the effect after painting latex paint is not as good as the interior wall putty!

Yes, the effect will be better, because the main difference between interior and exterior wall putty powder is that the exterior wall powder has more waterproof effect and higher strength; The interior wall powder is not waterproof, the wall of the home accidentally got water, and the slag will fall off the skin after a long time, my house is the exterior wall putty powder used indoors, and the effect is very good. With good quality.

Yes, but you have to consider whether it is safe to perform as a gas.

The waterproof glue powder on the wall is better than the waterproof glue powder on the inner wall, the putty ash on the outer wall is not flexible enough, the inner wall is easy to break, the putty powder on the exterior wall is relatively thick, and the use effect of the interior decoration wall is relatively poor, of course, this is not completely impossible, but the cost is relatively high. The decorative effect of the finished paint is not as good as that of the interior putty. Protecting the environment is not as good as indoor putty.

If used indoors, waterproof putty can be purchased.

However, it is not recommended to use it in this way, and the putty powder of the exterior wall does not meet the environmental protection standards of building materials, because the exterior wall must use glue in order to achieve water resistance, and excessive glue will produce formaldehyde and other pollutants, which will affect people's health.

OK. However, it is not recommended to use it in this way.

Reason: Exterior wall putty powder does not meet the environmental protection standards of building materials, because the exterior wall must use glue in order to achieve water resistance, and excessive glue will produce formaldehyde and other pollutants. If it is used as interior wall putty powder, it will affect human health.

Interior wall putty powder:

1. The base layer should be solid, clean, roughly flat, and free of open water, and the strength of the base layer should be greater than or close to the strength of putty.

2. The base layer with strong water absorption should be moistened with water or sprayed with glue for back sealing treatment, and then putty should be scraped (the consistency should be suitable for construction).

3. The newly plastered cement wall should be scraped putty after the curing period.

4. Stir evenly according to the ratio of putty powder: water = 1:, let it stand for 10 20 minutes and stir it evenly again.

5. Use a steel scraper or spatula to scrape according to the conventional batch, the number of scraping and coating should not be too much, usually two batches of scraping, and the second coating can only be constructed when the front coating is dry.

6. Batch scraping thickness, dosage 1, generally two times can be.

7. After the putty is dry, polish it with 320 or 240 sandpaper, and paint or paste the wallpaper as soon as possible.

8. Dosage: In the case of flat base, each kilogram of putty powder can be about square meters of flat wall.

We recommend exterior wall putty powder as interior wall putty powder. Because interior wall putty powder has its own characteristics, exterior wall putty powder is the same, and it also has its own drawbacks. The composition is different, the exterior wall putty powder is mainly white cement, and the interior wall putty powder is mainly gray calcium and heavy calcium. The water resistance is different, and the exterior wall putty powder has very good water resistance after drying, mainly because the content of white cement is different or the content of redispersible latex powder is different.

The exterior wall putty powder cement content is high, so it is generally more alkaline. The interior wall putty powder is relatively delicate to meet the characteristics of interior wall construction; The grinding performance is also better than that of exterior wall putty powder, and the decorative effect of latex paint is better at the back. Exterior wall putty powder is stronger; The construction is relatively difficult.

**Generally exterior wall putty powder is more expensive. There are also a lot of interior wall water-resistant putty on the market, and choosing a good line of interior wall water-resistant putty powder can fully meet your requirements.
