What is the difference between mildew putty and ordinary putty

Anti-mildew putty has the dual effect of architectural decoration and anti-mildew effect. It has a wide range of high-efficiency and long-term sterilization and inhibition capabilities for molds and yeasts, and a certain amount of mold inhibitors or inorganic nano powders that inhibit mold are added to the manufacturing process of anti-mold putty.

The fundamental difference between ordinary decorative putty is that ordinary putty is not mold-proof.

Putty. This entry is reviewed by the "Popular Science China" Encyclopedia Science Entry Compilation and Application Work Project.

Putty (mud filling) is a decorative material that flattens the surface of the wall, is a thick paste paint, and is an indispensable product before paint painting. It is applied to the primer or directly to the object to remove uneven defects on the surface of the object to be coated.

It is prepared with a small amount of lacquer base, additives, a large number of fillers and an appropriate amount of coloring pigments, and the pigments used are mainly iron red, carbon black, chrome yellow, etc. The fillers are mainly calcium bicarbonate, talcum powder, etc. It can be used to fill partially recessed work surfaces, or to scrape off the entire surface, usually after the primer layer has dried, and then apply to the surface of the primer layer.

Good adhesion and no cracks are required during the baking process.

<> "The difference between mildew putty and ordinary putty.

The main differences are the difference in water resistance, the difference in cost, and the difference in adhesion

1. The water resistance is different.

Ordinary putty does not have good water resistance, and the original wall paint must be removed and cleaned up during decoration, and then the putty can be scraped again. This situation will lead to an increase in decoration costs and a waste of resources, because the waste removed will cause certain pollution to the environment; After a few years of redecoration, the anti-mildew putty does not need to shovel down the putty layer first, only need to do a good job of local repair, you can directly carry out the next process, and the service life of the general high-quality anti-mildew putty is also relatively long, and the wall can basically have the same life.

2. The cost is different.

The unit price of mildew putty is 1-2 times that of ordinary putty, but although ordinary putty ** is cheaper, it cannot achieve the decorative effect of mildew putty, and from comprehensive considerations, such as the amount of paint and the cost of putty and construction costs during secondary decoration, the cost of mildew putty is low, and the unique whiteness and density, from the point of view of adhesion and coverage rate, can save 25 30% of the amount of paint compared with the wall of ordinary putty, so the cost is cheaper.

3. The degree of adhesion is different.

Anti-mildew putty has a high degree of adhesion, ordinary putty generally has a bonding strength above, and the strength after immersion has no requirements, while waterproof putty requires the bonding strength to reach, and the bonding strength after immersion in water is above. It can be seen that the strength of anti-mildew putty is much higher than that of ordinary putty, and it is not easy to produce hollowing and falling off.

1. The water resistance is different.

Due to the poor water resistance of ordinary putty, it is necessary to be careful when decorating in the future, and then clean up the putty together with the original paint, and then scrape the putty again. Not only does it increase the cost, resulting in a waste of resources and an increase in decoration costs, but also the waste that is removed will cause pollution to the environment. When the waterproof putty is re-decorated after a few years, there is no need to shovel off the putty layer, and the next process can be carried out after partial repair, usually a good waterproof putty can ensure the same life as the wall.

2. The cost is different.

The unit price of waterproof putty is 1 2 times that of ordinary putty, but the decorative effect after making waterproof putty is far beyond the reach of ordinary putty. Moreover, from the comprehensive calculation of the amount of paint and the cost of putty and construction costs during the secondary decoration, the cost of using waterproof putty is low. The unique whiteness and density of waterproof putty make the adhesion and coverage rate of paint per unit area save 25 to 30% of the amount of paint compared with the wall using ordinary putty.

3. The degree of adhesion is different.

Waterproof putty has a higher degree of adhesion than ordinary putty. The standard state bonding strength of ordinary putty is greater than that, and there is no requirement for the sock head for the strength after immersion, while the waterproof putty requires the bonding strength in the standard state to be reached, and the bonding strength and width after immersion are greater than that. It can be seen from the standard that the strength of waterproof putty is higher than that of ordinary interior wall putty, so the use of water-resistant putty is not easy to produce hollowing and falling off.

<> "What is the difference between mildew-proof putty and water-resistant putty?"

There are four main differences, namely water resistance, adhesion, strength and cost

1. Difference in water resistance.

The water resistance of anti-mildew putty is not as good as that of water-resistant putty, and it is suitable for areas such as basements and bedrooms that are not in direct contact with water, while water-resistant putty has strong water resistance and is suitable for outdoor walls to block moisture from entering indoor walls.

2. Difference in adhesion.

The adhesion of anti-mildew putty is not as good as that of water-resistant putty, and the water-resistant putty still has adhesion after being immersed in water, which can meet the requirements of batch scraping. The adhesion of the anti-mildew putty will become worse after touching the water, and the putty layer will peel off and become moldy after a long time.

3. Difference in strength.

Anti-mildew putty is only suitable for indoor batch scraping, not for outdoor walls, relatively speaking, it has limitations. The water-resistant putty can be used for outdoor and indoor walls to meet its scraping needs, suitable for a variety of substrates, good bonding strength, and basically no hollowing and falling off.

4. Cost difference.

The cost of water-resistant putty is 1-2 times that of anti-mildew putty**, but the performance of water-resistant putty is relatively high, and the applicable base is relatively wide. However, from the material cost and construction cost of putty, the cost of water-resistant putty is relatively low. Moreover, the purity and density of water-resistant putty are much higher than that of anti-mildew putty, so that the adhesion and coverage rate of construction per unit area are about 30% less than that of anti-mildew putty, so it is more cost-effective.

Kitchen, bathroom with anti-mildew putty, others with ordinary putty can be.

Distinction: 1. Anti-mildew putty will be better in anti-mildew That is to say, it can prevent the wall from becoming mildew to a certain extent.

2. Ordinary putty is ordinary putty, mildew-proof or something, not as good as mildew-proof putty, just like waterproof putty, which will have a certain effect on waterproofing, and it can prevent the wall from being damp and mildew to a certain extent.

3. This will be written on the product packaging If it is not written, it is not Don't listen to what those businessmen say This has anti-mildew and anti-mildew putty or something In fact, what is not written is different.

Antimicrobial agents are added to the anti-mold inside.

There are not many poor results, ** the difference is very large.

Look at what you're using, it's not a special environment.

This can be seen from the name.

Anti-mildew putty will be better in anti-mildew, that is, it can prevent the wall from mildew to a certain extent.

Ordinary putty is ordinary putty, mildew or something, not as good as mildew putty, just like waterproof putty, it will have a certain effect on waterproofing, and it can prevent the wall from being damp and mildew to a certain extent.

This will be written on the product packaging, if it is not written, it is not, don't listen to what those businessmen say, this has mildew-proof, and mildew-proof putty or something, in fact, what is not written is different.

Anti-crack putty is used on the outside of the insulation layer of the exterior wall, and flexible water-resistant putty is used for the interior wall.

Generally speaking, putty is distinguished from water-resistant putty, moisture-proof and mildew-proof putty, and ordinary putty.

For the exterior wall, it is mainly water-resistant putty and ordinary putty, simply putty is not afraid of water, and there is no problem in soaking in water all day long, and it will not fall off. Ordinary putty is not good, and it is very easy to fall off when soaked in water.

Moisture-proof and mildew-proof putty is mainly for interior walls: for the damp environment of the interior wall, such as the basement and the phenomenon of returning to the south sky, it plays a moisture-proof and mildew-proof role to prevent the wall from becoming mildew and black.
