How to prepare a ceiling for painting with water-based paint: whether it is necessary to wash it off with your own hands and how correctly, grouting concrete than washing and how, video

It is extremely important to properly prepare the surface of the before painting. The ceiling and walls have been very popular with water-based paint recently. This is due to the fact that this material is practical and durable. Before applying to the surface of the concrete ceiling paint, you must properly prepare the surface. This will ensure a better grasp of the material. To make a training by one's own hands is easy. The main thing is to follow a number of simple rules.

How to prepare the shelf for painting

Surface preparation begins with a primer. It is worth noting that you need to start this process after you remove the whitewash from the surface. To finish the concrete ceiling, it is necessary to use primers with a deep penetration. These materials will protect the ceiling from fungus and mold. Alternatively, general primer materials can be used.

If you want to prepare a wooden ceiling, you should use specialized impregnations. They will reduce the risk of rot on the surface. In addition, such impregnations will protect the ceiling from bedbugs and other pests.

Primer is an important stage in the preparation of the ceiling, as it helps protect the surface from fungus and mold

Ceiling primer algorithm:

1. First, dilute the mixture.
2. After this, pour the primer into the bath. It is desirable that the bath has a flat ribbed configuration.
3. Dip the roller into the bath.
4. Roll the roller on a ribbed surface.
5. Apply the mixture to the surface.
6. After this, wait until the first layer dries, and apply the second one. If you want to speed up the drying process, use a heater.
7. After work is finished, stick adhesive tape on the ceiling. If it will hold, then you put the mixture on the surface correctly.

Do I need to wash off the ceiling before painting the surface

If you are preparing the ceiling for painting, then you need to wash off the whitewash from the surface. Otherwise, the water-based paint will not fall well. Grout is made with the help of vinegar, soda, roller, spatula, foam sponge and polyethylene film.

Before painting the ceiling with water-based paint, it is necessary to completely wash off the old whitewash

Cover the furniture with film before starting work. Then you need to prepare the mixture. To do this, mix 10 liters of water, 3 tablespoons of soda and 2 tablespoons of vinegar. Stir the mixture to a homogeneous consistency.

Grouting is carried out in the following order:

• Before washing the ceiling, moisten the surface with water. In order to speed up the wetting process, you can use a special spray gun.
• Then, with a spatula, carefully remove the whitewash. If desired, you can additionally wet the surface.
• Dip the foam sponge into a pre-prepared mortar.
• After this, rinse the remaining whitewash from the ceiling. Then allow the surfaces to dry out, and start applying the putty.

Prepare the ceiling and walls for painting with your own hands

After you have removed the whitewash and applied the primer to the ceiling, you need to start strengthening the surface. This procedure will help to give the surface extra strength. To strengthen the surface you will need a fiberglass.

Ceiling reinforcement algorithm:

1. Treat the ceiling area with a glue solution.
2. Press the first piece of fiberglass.
3. Grease the other section of the ceiling with glue and press the second piece of fiberglass to it.
4. With a stationery knife, make a common cut. It is desirable that he was in the place of overlap.
5. Remove excess webs.
6. Glue the entire ceiling.
7. Wait until the fiberglass has dried and apply the next layer of adhesive.

After reinforcing the surface, proceed to the putty. In order to qualitatively level the surface, you need to perform this procedure in a darkened room. Use a light bulb as a light source.

Before applying the putty, the ceiling must be reinforced with fiberglass

Apply the filler in the following order:

• First, prepare the putty mixture.
• Apply the first coat. After it has dried, apply the following. Remember that the second layer must be perpendicular to the previous one.
• Use a sanding paper to treat the surface.
• Then apply a thin coat of primer, and on top of it several layers of putty.

Surface grinding for painting

The final preparation stage is surface grinding. You can do this manually. To do this you will need a specialized grater. If you do manual grinding, be sure to use a respirator and glasses.

When choosing a grater, consider the following nuances:

1. Do not use a solid grater with grooves.
2. It is recommended to choose graters to which a grinding network or sandpaper is attached.
3. If you choose between sandpaper and mesh, give preference to sandpaper. This material is more durable. In addition, the grinding network wears out quickly.
4. Use sandpaper made from fabric material.
5. Pay attention to the graininess of the sandpaper.

If you are using a grinding machine, be sure to attach a heat insulating plate from the seal to its sole. Its thickness should be at least 3 millimeters. This technique will protect the instrument from wear and tear.

For grinding the ceiling, it is better to use a special grinder and, without fail, respiratory protection

When working with a grinder, consider some of the features:

• Before proceeding with grinding, On the rack you need to install a light bulb. This technique will help you to identify irregularities on the surface easier.
• For finishing, use mesh No. 100.
• When working with the machine, monitor the degree of mesh wear.
• During operation, use a dedicated stand. If you have the opportunity, use machines on which a special rod is installed.

It is not difficult to prepare the preparatory works. Start the work with the elimination of defects using sealants or putty. Only after this it is necessary to start the priming and subsequent work. When choosing materials, it is necessary to take into account the material from which the ceiling is made. Also do not forget to carefully polish the ceiling. If the surface is rough, the paint will be better to lie down.
