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

Putty powder is a kind of surface-leveling powdery material that is used to pretreat the construction surface before the paint is applied. According to the formulation and water resistance of the putty powder, we can divide the putty powder into the exterior wall putty powder and the interior wall putty powder. In the construction industry, there is a saying that the interior wall is not used externally, and the exterior wall is not used internally. That is, the interior and exterior wall putty cannot be confused. Therefore, the two putty powder formulas are different. About the interior and exterior wall putty powder formula , Xiao Bian here will do a detailed introduction for everyone and the difference between inner putty powder and putty powder on the wall. Interested friends can take a look.

Putty powder

Putty powder is an indispensable decoration material in decoration, which belongs to a kind of wall surface leveling and repairing base material, and is a good foundation formed for brush painting and decoration of other decorations. The wall surface is painted with putty powder, which can maintain a good smoothness and has a uniform effect, so that the future decoration works can be performed better. It is an indispensable material in the decoration.

Putty powder is generally based on the base material, filler, water and additives, but also can add some fiber components, can play a good role in crack resistance. Usually, the base material of putty powder is gypsum or cement, so that its surface is rough but can be easily bonded. Generally, the base layer can also be coated with an interface agent to seal the base layer and improve the adhesion of the wall surface during construction. The purpose of doing so is to be able to better increase the bondability of putty powder and make the construction more convenient.

Inner wall putty powder:

PuTTY powder is a one-component interior wall putty powder made of high molecular polymer, methyl cellulose ether and other raw materials. The putty powder produced by our factory has good characteristics such as good sturdiness, bonding strength and good waterproof capacity. It is suitable for high-end venues, hotels, restaurants, convention centers, and families, as well as high-end venues that need to prevent the infiltration of external walls.

Product Features: The walls of putty powder fiber can be washed with water, do not fall off, do not fall off, and slight impact without leaving marks.

How to use: PuTTY powder is mixed with water and stirred for 10 minutes. The paste putty is left standing. After 5 minutes, it can be scraped on the wall. Generally, it is scraped twice. The second time it is scraped, it must wait the first time. After drying, sandpaper should be used immediately (within 24-48 hours). After the leveling, the dust on the entire wall should be removed, and the latex paint can be applied after being dried.

Safety and stability: Normal and high temperature decomposition are non-toxic and chemically stable.

Exterior putty powder:

The putty powder is made of imported high polymer polymer redispersible powder, mixed with methyl cellulose ether, modified starch ether, anti-crack fiber as the putty powder mixture weight ratio (3%), and other advanced high-grade putty made of other raw materials. The powder has strong resistance to the micro-cracking of the wall, and has the characteristics of good forehead viscosity, impermeability, reliability, and no shrinkage.

Product features: The putty powder produced by our factory has good crack resistance, which greatly saves the overall strong maintenance cost.

How to use: Put the wall putty powder into water and stir it into a paste for 5 minutes. Then apply it on the wall. The general thickness should not exceed 2-3mm. According to different requirements, it can be divided into one to three batches to increase the thickness.

Matters needing attention: As the external wall putty powder has good water retention capacity, it can slow down the solidification and avoid the occurrence of early dry shrinkage cracks. Therefore, care should be taken during construction to ensure that the first layer is dry before the second layer can be used. The temperature of the construction environment must not be less than 5 degrees. It cannot be constructed on rainy days.

The difference between inner putty powder and exterior putty powder:

The interior wall putty powder has its own characteristics, the outer wall is also the same, but also has its own drawbacks, why not recommend the use of interior wall putty powder as a wall putty powder used? First we look at their own characteristics, the external wall Putty powder is highly resistant to earthquakes, flexibility, weathering, and water resistance. Interior wall putty powder requires environmental protection and other properties. In order to achieve weather resistance and super water resistance, glue must be used. Although this glue is environmentally friendly, it will become environmentally unfriendly if it is added in a large amount. Therefore, if the interior wall putty powder is used as an exterior wall, its weather resistance and super water resistance are up to Not to.

Exterior Putty Powder Formula

1. Stone powder + gray calcium + cement + cellulose + powder (EVA, PVA);

2, the wall putty powder and water in accordance with the ratio of 3:1 added to the container, stirring for 5~10min;

3. Stir the putty for 10 minutes after stirring and stir it again. The second stirring for 5 minutes can be used for scratching.

Remarks: When using, add clean water (normally the ratio of water to powder is 1:2-3), the preparation container must be clean, and mix it with electric stirring for 20 minutes, so that the polymer in the product can be fully reconstituted and hydrated before use. Stir and scrape once.

Interior wall putty powder formula

1, heavy calcium (or talcum powder) 70% ~ 80%, gray calcium (lime powder) 20% ~ 30%, plus fiber appropriate amount of cellulose;

2, interior wall putty powder: water = powder: water = 1:0.35;

3. Add appropriate amount of fresh water to the bucket, pour the putty powder into water, and mix it with an electric stirrer for 3-5 minutes until it is evenly filled with no paste, put it aside for 5-10 minutes, and stir it 1- 2min can be scraped for use;

4, due to the different flatness of the grass-roots level and the difference in construction levels, each putty consumption is different, generally 0.6-0.8kg/m2.

Note: Stir the good putty should be used within 3h, dry hard putty must not be mixed with water after mixing, the product should be stored in a dry place, no exposure, rain, damp, frost.

Editor's summary: The relevant information on the differences between interior and exterior putty powder formulas, inner putty powder and exterior wall putty powder was introduced here for everyone. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom.
