Is it OK to scrape putty powder on the wall? Will it cause formaldehyde problems?

The environmental performance is very superior, after a short period of ventilation, the formaldehyde of latex paint will also be quickly emitted, so for indoor wall decoration only scrape putty without painting, coco thinks it is okay, but it is not recommended. First of all, whether there is formaldehyde or not has nothing to do with who scrapes the putty, even if the top master scrapes it out is toxic or toxic, if from the artistic effect, it is completely okay to only scrape the putty, as for the problem of formaldehyde, it depends on the composition of the putty itself, not the craftsmanship of the construction.

The formaldehyde content of the putty itself is relatively small, but some masters will add kraft glue when batching putty, so that the formaldehyde content will be relatively large, and then the latex paint, it will also contain formaldehyde, because the place where there is glue must contain formaldehyde, that is, how much is the content, but now the aldehyde content of the materials of the big brands is relatively small, and few people react to the formaldehyde problem of general wall putty powder, and formaldehyde mostly exists in the glue of furniture and floors. For the sake of safety office furniture, please choose a qualified and guaranteed after-sales manufacturer, and recommend you to pay attention to Shengao office furniture. The decoration of the new house should be ventilated as much as possible.

Putty powder, which uses glue as a binder, has been gradually phased out. In addition, when decorating, we must pay attention to whether the putty powder is deployed on site, if it is deployed on site, workers may use construction glue or glue powder for blending in order to pursue the cost, resulting in the release source of formaldehyde. Generally speaking, putty powder is a natural inorganic mineral and is not toxic.

It's just that engineering putty is usually prepared on site, and in order to increase the adhesion of putty powder, a large amount of construction glue is added to it, and there is formaldehyde in the glue.

There is no formaldehyde in the putty itself, if it is brushed with latex paint, there will be a small amount of formaldehyde, but the development of building materials to this day, the latex paint content of large manufacturers on the market is very small, so rest assured office. In the wall decoration, scraping putty during the base treatment is an indispensable step. And when treating the base layer of the wall, some people will use some commercial glue, such as 801 glue.

The putty material itself is formaldehyde-free. However, some decoration personnel will add some thickeners when preparing putty for the sake of good-looking, beautiful, convenient and other factors, such as engineering glue, cooked paint, etc., which contain formaldehyde. Therefore, it is better to ventilate for a few days after scraping putty powder before moving in.

Formaldehyde is mainly the glue in furniture, other paint powder or some other decoration materials will only release a small amount of formaldehyde, putty powder will not have too much formaldehyde.

In fact, it is still very good, if you use more environmentally friendly materials, then it will not produce a lot of formaldehyde.

Under normal circumstances, putty powder does not have any formaldehyde components in it.

In general, putty powder is a natural inorganic mineral deposit and is not toxic. It's just that engineering putty is usually prepared on site, and in order to add the adhesion of putty powder, a large amount of construction glue (rich in formaldehyde) is added to it, which makes people talk about aldehyde discoloration.

Other engineering putty powder may also use a thickener similar to the resin such as clear oil or cooked paint, and its volatiles are slightly toxic, and the content is very low, and the volatile substances are subject to relevant standards, which will not have much impact.

Precautions for scraping putty:

The finished putty is produced according to the reasonable material ratio and mechanized method, which avoids the error caused by the on-site ratio in the traditional process and the problem that the quality is not guaranteed. It is green and environmentally friendly, non-toxic and tasteless, does not contain formaldehyde, benzene, xylene and volatile harmful substances, is ready to use with water, easy to operate and simple in process.

Is putty powder good? Putty powder is formulated with a small amount of lacquer base, a large amount of filler and an appropriate amount of coloring pigments. 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 is required and no cracks occur during baking.

Scraping putty has no formaldehyde.

Under normal circumstances, interior wall putty powder is formaldehyde-free, and putty used in construction is divided into ordinary putty and water-resistant putty. Ordinary putty is dedicated to indoor use, which is generally composed of heavy calcium powder and rubber powder. The main ingredient of calcium powder is calcium carbonate, which means that there will be no formaldehyde in the fine noodles ground from stones.

At that time, everything made of gray calcium powder and cement did not contain formaldehyde, so you can rest assured when you use it.

Putty powder is one of the indispensable decoration materials in interior decoration, usually when the wall is decorated, putty powder will be painted for base leveling. When you apply putty to a highly absorbent base layer, you need to wet the wall with water first. Then brush the putty, generally the putty should be brushed twice, and the thickness of the batch scraping is about right.

After the putty has dried, it can be sanded with sandpaper, painted with paint, or pasted with wallpaper.

Purchase Notes:

When purchasing putty, it is necessary to look at the test report of the product, whether there is a ten-ring Duanchun certification logo, etc. When you buy putty powder products from well-known brands, you should see whether the merchant has an authorization letter. When buying putty, it is also necessary to see whether the product packaging is Hongxian has the implementation standard, weight, production date and other relevant information.

Do not buy expired products, if the putty powder has passed the expiration date, there will be problems such as no stickiness, and try not to buy non-finished putty. You can feel the putty with your hands to see if it is delicate enough. If putty is divergent and has pinholes, it means that it is of inferior quality.

At the same time, in order to avoid others from counterfeiting the products, many manufacturers will affix their own anti-counterfeiting marks, usually scratching off the coating to dial ** to distinguish the real from the fake.

There is formaldehyde. Under normal circumstances, putty powder does not contain formaldehyde, but if it is directly mixed with putty powder with water, it does not contain formaldehyde. However, the adhesion between the putty powder mixed with water and the wall is not high, so in order to increase the adhesion of the putty to the wall, glue will be added to stir, and formaldehyde in the glue is unavoidable.

How to make wall putty? 1. Shovel wall skin, you can do a slight moisturizing test to check whether the adhesion of the original coating is qualified, and the vast majority of the wall surface has been inspected in one word: shovel!

The wall is closed with 801 glue to enhance the adhesion between the putty and the wall. If you encounter an old house, you can brush the interface agent to increase the insurance factor. The yin angle is treated with the "elastic line" on both sides (pay attention to the verticality), and the yang angle is treated with a leaning rod.

Use gypsum powder and 801 glue to prepare gypsum putty, and straighten all the gypsum putty. In general, plaster lines are not recommended.

2. Leveling the wall, first check whether the wall has a "hollow drum" (can be struck, listen to the sound and noisy to judge), and then use a slightly longer aluminum alloy ruler to check the depression of the top and the wall, mark it, and flatten it with gypsum greasy lead.

3. Formally scrape the putty, and after the gypsum putty is dry, scrape and apply the putty (each time it must be thoroughly dried). There are two ways to test whether the putty is dry: first, observe whether the color is consistent; The second is to see if there is a phenomenon of "sticking sandpaper" when sanding.

Strong light oblique grinding, the top surface can be 360 sandpaper.

How to hang the net with batch putty? The procedure for the hanging net on the wall is to brush the glue first, polish the putty two to three times, and then level it. After that, it is a brushing of paint, brushing the matching primer once, and the topcoat twice.

1. Before the decoration wall treatment, the most important thing is to check the wall to see if it is solid and smooth. If there are cracks or holes in the wall, they need to be repaired and leveled with plaster.

2. Prepare the materials for decoration wall treatment to protect the materials and furniture in the room and clean the floating dust in the room. Then roll the concrete interface paint evenly on one side, and after it dries, you can start scraping the putty. If it is a newly built wall, you need to wait for the 28-day cement curing period before scraping putty.

3. Scrape putty for decoration wall treatment, generally scrape the putty on the wall 2 times, the wall with poor flatness needs to be scraped several times, and the more serious ones need to be leveled by gypsum first, and each putty scrape needs to be more than 2 hours.
