How to make a primer for walls with your own hands. In order for the finishing layer in the form of decorative plaster or paint to stay on the wall as long as possible, before finishing work, it is required to first cover the wall with a layer of primer. In the construction supermarket at the moment there are a huge number of primer varieties on sale, which are produced by many manufacturers.
But not every person knows how to make a primer with his own hands, which will have a much lower cost than the finished one.
As stated above, Primer Compound helps extend the life of the wall covering and also improves the adhesion of the finishing material to the wall surface .
.. a primer is a liquid mixture that is applied to the surface of the walls in an even layer, and as it dries, it creates a dense film on which paint, plaster, wallpaper and other types of coatings will perfectly fit. If plaster is falling from the surface of the walls in your apartment or house, and the walls themselves are dilapidated and loose, then the plaster will help to strengthen them additionally in tandem with a primer.
Based on what functions the primer will necessarily perform, it can be divided into the following varieties:
Moreover, the primer has antiseptic and anti-corrosion properties. In certain formulations, the use of additional components can impart refractoriness to the surface.
Please note, what is worth knowing that priming the working surface is required for almost all finishing works, for example, when plastering aerated concrete and foam concrete walls, painting works like painting concrete floors or even slate.
So, before you prepare a primer yourself at home, you should decide what functions it should perform, since its further composition will depend on this.
The question of how to make your own primer mixture for the surface of the walls, at the moment, worries many people. But it seemed that such a thing if you can just go to the nearest construction market and buy a ready-made solution? But if you take a closer look at the walls, then you will understand that there is a difference, and a big one. The primer consists of very inexpensive and simple components. The most important thing is that the composition is correctly selected and the exact amount of all elements is calculated.
How to make a primer mixture that will increase wall strength
To prepare a surface primer, you will need to take the following components:
A suitable sized saucepan or enamel bucket. Ideally, the dishes should be unnecessary for the future, because after preparing such a solution, it will not be possible to cook food in the dishes.
And now step-by-step instructions:
Stir the mixture from time to time to avoid lumps.
Good advice! If during cooking you miss the moment and lumps still form in the solution, then you can get rid of them if you use a standard mixer or even a hand blender. But be careful not to break the technique.
Rinse thoroughly immediately after removing the mixer from the solution.
To ensure the walls of your home or apartment are protected from adverse environmental conditions, you need to use a primer with deep penetration , which is most often made on the basis of PVA glue. To create a deep penetration primer, you will need to buy construction PVA glue, which will ideally cope with the task of increasing the strength of the walls and their waterproofing. Although it may seem that with such useful properties of PVA construction glue, they could also replace the primer. But this categorically cannot be done, since PVA glue on the surface of the walls is able to form a moisture-proof film, which after a while will begin to peel off along with the layer of plaster.
Moreover, you probably remember from school that PVA glue has the properties of starting to turn yellow after some time, and this negatively affects the appearance of the finish, in particular on the wallpaper.For this reason, PVA glue must necessarily be used, but not as a main element, but only as an additive.
Making a primer from PVA glue is quite simple, and for this you need the following components:
Little is required from you - mix glue with water, add cement to the mixture, mix everything well together, and then strain through several layers of gauze or a sieve. The advantage of this method is that preparing the primer with your own hands is simple, convenient, and there is also no need to spend time to first bring the mixture to a boil, then cook it, and then wait until everything cools down. a primer made on the basis of PVA glue will be ready for use immediately after you strain the finished solution. The only drawback is that it can be stored for no more than a day, so it will not be possible to stock up on such a solution for future use.
There is also a little trick to determine if the proportions of glue, cement and water that have been used are correct.
Before you start treating the walls with a primer solution, you should apply it to a small section of the wall and let it dry. If, as a result, a dense film did not appear on the surface of the site, then the proportions were taken correctly, and the priming process can begin.
Among other materials, wood processing is perhaps one of the most difficult tasks. First, you need to figure out in which cases the wood should be primed at all, and when you can only cover the surface with a special impregnation.
Priming of wood is required if:
Acrylic, alkyd, shellac and antiseptic primers are usually used for additional protection of the wooden coating, but they are special, and it will be risky to take on their own production. Wood is a rather capricious material, and if you experiment with it using different types of primers, there is a high probability of damaging the material.
Therefore, in this case, it is better to use ready-made priming solutions.
Some of the DIYers were able to save a lot of money and at the same time make life easier by simply combining wallpaper glue and a primer mixtures in a single solution.In this case, wallpaper glue will play the role of an alternative replacement for construction PVA, since it has similar physical properties and penetration depth. Another advantage of replacing PVA glue with one for wallpaper is that you do not need to wait until the primer layer dries. Once you have treated a section of the wall with wallpaper glue, you can immediately apply a sheet of wallpaper of the desired size to it.
And at the end we will tell you a little about how to apply the priming layer correctly:
In addition, experts advise applying a layer of primer with one sweeping movement of the hand, from the bottom up. Try to apply it so that the roller does not pass over the same spot twice, as otherwise the primer layer will be uneven.
To make the layer denser, let the first layer dry first, and only after that you can apply the second and the next layers.
