Can indoor concrete floors be painted?

Indoor cement floors can not be painted, paint is harmful to human health.

The cement floor is finished, and the treatment is good and beautiful.

But a set of processes is not cheap to do.

1) Leveling. 2) Sand treatment.

3) High-strength anti-cracking mortar.

4) Cement floor polishing.

5) Cement dyeing.

6) Cover wax. Cement walls can be painted, but they also need to be treated first, and at the same time, when painting, it is not just one layer, but may be multi-layered, so special attention should be paid when painting.

2.Cement wall brush coating steps: base treatment.

The new cement mortar wall should not be painted, and it is generally necessary to wait for half a year before brushing the oil. If you have to paint, you can wash the wall with water every 2 to 3 days, and repeat it many times. Before brushing the oil, 10 20% dilute hydrochloric acid water should be applied once to neutralize the residual alkali in the cement mortar layer, and then brush the acid water with clean water and dry it after a while.

In this way, the surface layer of the new cement mortar will not bite the color, lose the light and roll up after the paint.

3.Cement wall brush coating steps: the old cement mortar wall is good to first use pig blood material and water to make a rice soup shape, use a pen to brush the cement mortar wall once, and then scrape the pig blood putty after drying.

Generally, the surface dust should be removed before the cement mortar wall is painted, and the cracks, depressions and other damaged places should be filled with gypsum putty.

4.Cement wall painting steps: Painting is also a very critical step.

Many designers think that it is better to choose alkyd enamel or phenolic enamel, which has a good finish, is easy to dry, and is more convenient to brush. Generally, the wall can be brushed with magnetic paint twice, and the second time should be brushed after it is dry. The direction of movement of the oil brush during brushing should be left and right and downward brushing, so that the brush is uniform and the joint is not easy to see.

The indoor cement floor is painted with epoxy flooring.

Epoxy floor paint is very good. It is a three-component product consisting of a main coat, a thinner, and a hardener. The amount of curing agent determines the wear resistance of the paint.

This type of paint is used on the floors of many commercial shops and studios. The service life can reach more than 5 years.

Nowadays, many families will choose epoxy floor paint, which is a very common type, and the range of adaptation is very wide, not only can be used, but also is very suitable for the decoration of the ground in some public places.

What is the method of painting cement floors?

1. First of all, the ground ready to be coated with cement is cleaned, (no river sand and no dust) The thorough way is to sweep the dust with a broom first, and then drag it again with a mop. It is mixed with tung oil and rosin perfume in the same proportion, stirred evenly and then applied to the ground. This can effectively enhance the adhesion between the cement floor and the putty.

2. Next, enter the deployment link of introducing putty. At present, the putty used in decoration is divided into two types: gypsum putty and blood putty. And the preparation method of blood putty is:

Pig blood and large white powder, according to the ratio of 16::56 for blending, of course, in order to enhance the waterproof and wear-resistant performance of putty, it is also necessary to mix a certain amount of cooked tung oil.

The preparation method of gypsum putty is: gypsum powder, cooked tung oil, pine perfume, tap water, according to the ratio of 16:5:1:6, stir evenly and use.

3. After the putty is evenly mixed, we should enter the next environment, scrape the putty to the ground with a shovel to brush the paint in advance, and it is generally more appropriate to scrape two to three articles, in short, the ground can be scraped flat, and then after the putty is dry, polish it with 80 mesh sandpaper, and you can brush the floor paint.

In the process of painting floor paint, pay attention not to be greedy, and the floor paint should not be applied too thick to avoid wrinkles. The floor paint is not one time can be brushed, generally it takes about two times, in the second time to make sure that all are dry, and then the floor is waxed and varnished, so that it is done.

Summary. Dear, the paint can not be brushed directly on the concrete floor. The cement floor can not be painted directly, we should use a broom to clean the ground dust before painting, because the presence of dust on the ground will affect the adsorption of the paint.

In addition, the combination of paint and cement is poor, before painting on the cement floor, we can apply a layer of putty on the ground or use a grinder to polish the cement floor, so as to improve the adsorption capacity of the paint and so on.

Can paint be brushed directly on concrete?

Dear, the paint can not be brushed directly on the concrete floor. The cement floor can not be painted directly, we should use a broom to clean the ground dust before painting, because the presence of dust on the ground will affect the adsorption of the paint. In addition, the combination of paint and cement is poor, before painting on the cement floor, we can apply a layer of putty on the ground or use a grinder to polish the cement floor, so as to improve the adsorption capacity of the paint and so on.

Supplement: What should we pay attention to when painting on the cement floor 1. If we want to paint on the cement floor, we must choose the paint with good wear resistance, for example, we can paint the floor paint. Try not to brush the floor with ordinary paint, because the resistance of ordinary paint is poor, and it is easy to peel on the ground.

Moreover, the wear resistance of ordinary paint is relatively poor, and the ground is easy to have problems such as paint fading after a long time of ordinary paint. 2. Before painting the cement floor, we must check whether the ground is dry. You can use a piece of plastic sheeting to cover the ground, press the plastic sheet with sand around it, and after a day, open the plastic sheet to check for water droplets.

If there are water droplets, it means that the ground has not dried thoroughly, and at this time, direct painting will affect the formation of the paint film and so on.

Yes, but not recommended. Ordinary paint has poor resistance and other factors, and it is very unsuitable for brushing the floor, so floor paint should be used.

Cement floor paint is mainly used for the protection of concrete or mortar floors. And for the concrete to provide a neat and beautiful, anti-corrosion, wear-resistant, decorative to the ground to play a protective role.

Because cement concrete is mostly made of Portland cement mixed with aggregates of various sizes, mixed with water, and then condensed by hydration. Therefore, the inherent porosity and brittleness of cement concrete, leading to its surface wear resistance is relatively poor, and it is easy to wear, whether it is the movement of people or the rolling of vehicles, a large amount of dust produced by frequent friction on the cement floor, in addition to affecting the neatness and beauty of the production workshop, also affects the normal progress of industrial production.

Therefore, the first function of cement floor is to carry traffic, cement floor paint must have enough compressive strength and hardness, with strong acid and alkali resistance, wear resistance, pressure resistance, impact resistance, mildew resistance, waterproof, dustproof, anti-slip and other characteristics, bright and diverse colors, easy to clean and a series of functions.
