Onethe most important elements of any repairs and construction is primed walls.What does it represent?

Waterproofing properties

waterproofing properties

primer for walls, floors, ceilings and any other construction element is designed to solve a huge pile of problems.Chief among them is the bond base.It creates a strong film that can withstand heavy loads.That it manages by deep penetration capabilities.These properties are the types of acrylic primer designed for concrete, plaster and putty walls.

chemical activity of the formula by reacting with the oxygen starts to polymerize (harden).In the plane of drawing substance crystals grow long artificial polymer which form strong bonds with each other.

second objective to be pursued and successfully implemented a primer - a waterproofing.Due to the formation of a dense film on the surface of the base mois

ture there is no room to penetrate deep into the wall.But it is a porous structure.

important function of any primer for the walls is corrosion protection and antiseptic.When applying it to the metal surface it provides maximum grip topcoats with a base material that provides resistance to wet environments.When using a primer for dry wall (brick, CBC block, plaster, putty), it acts as an antiseptic.It kills all kinds of micro-organisms that are even deep into the structure of the material and create antiusloviya for their future existence and occurrence.

types of primers for walls

today produced different types of primer mixtures for different types of material base of the wall:

  • for metal surfaces;
  • Bulk Cement porous structures;
  • for wood.

On sale there are also some types of primers, which are securely fastened, even with plastic products, which then allows them plaster, plaster or paint.It is composed of Compounding and resinous components.

The types of primers on different grounds

Primer walls under the wallpaper, the latest of which is covered mainly filler, the process would be an integral part of repair work.There are used an acrylic-based mixture.They have excellent penetrating ability that allows you to get a solid and reliable basis.Especially for wallpapers and such need.However, even the wallpaper paste can be used for the treatment of the walls of the bulk material.It has all the same properties as the acrylic primer, also thanks to the fairly thick consistency of the resulting mixture may be a means for leveling cracks, micropores and other small surface defects.

When preparing homemade primer for walls, to maximize the quality of the texture.To a perfectly smooth wall was not hardened clots and speckles, while stirring the glue in the container is inserted a piece of fiberglass mesh.On her stick all undissolved pieces of adhesive and debris that will further allow unimpeded dip the roller into the container.

If the walls are made of wood, which in the future it is necessary to glue the wallpaper, there are applied alkyd primer.They have a characteristic pungent odor, so the room should be well ventilated.Primer for plaster material that creates a durable coating, because it penetrates deep into the wood structure, bonding and preventing its desiccation.In addition, it is also a good remedy against various parasites.

sale as there is still a primer concentrate for walls, ceilings and floors of the loose surfaces and wood.This highly concentrated substance called acrylic dispersion before use is diluted with water in various ratios.The proportions of the components depend on the forthcoming works.

example, primer Armor concentrate is mixed with water in the following proportions:

for facade work - 1: 0.6;

for the purpose of work - 1: 0.8;

Interior finishing - 1: 1.

proportions of dilution per 1 m2 of water consumption and the area indicated on the packaging, so before use of a concentrate to be thoroughly acquainted with the instructions.

Priming of walls before plastering

Primer for plaster plays the most important role in the whole process of construction or repair.When the walls of the ASG blocks, bricks or concrete at its surface fine particles are always present the same material.They will be an obstacle to a lasting solution contact plastering walls and even a strong adhesive for tiles.Primer for plaster walls to resolve the issue of education chalk dust on the surface of these materials, is firmly fastened them to the main structure.Many people mistakenly believe that the wall just enough to moisten with water, and the solution will be fine hold.But this is not so, because even within a short period of time on a section of the wall is clearly visible from the backlog of plaster blocks or bricks, which can nullify all the work carried out.Therefore, to avoid these troubles and subsequent unforeseen costs should be carried out this important step.Thus necessarily need to wait for the complete drying time before further processing works.If loose and suspicious surface primer for plaster walls should be carried out several times, giving the previous layer is completely dry.

Priming the walls with a brush in hard to reach places

term drying and concentration of the dilution of primers is always indicated on the package, so be sure to read the instructions before using it.The average polymerization surface after treatment period is 24 hours at normal humidity and a temperature not lower than 150C.

primer before painting the walls

primer for painting walls

Today, there are many ways to finish the walls, which are subsequently painted colors of different types.But its lasting adhesion to the surface is also required to wash the walls before painting.Thus, depending on the type of finishing coating is chosen and the type or number of layers of primer.For sufficient water-based paints front and one layer of soil, but using oil or other types of coatings, it is better to perform processing in multiple layers.

technology and tools for priming walls

Choosing the type of material now look at how to prime the wall for painting.

to perform works on priming the walls need to roll for ground brush and container.

Many types of soil, even nearly all, begin immediately to set.Therefore, necessarily and personal protective equipment.This rubber gloves, a hat and breeches appropriate clothing.

brush is recommended for high-quality processing of the places in which the roller can not penetrate, even with a long nap:

  • angles;
  • depression;
  • openings;
  • projections;
  • decorations.

This brush bristles can be any non-rigid to prevent damage to the base (plaster).Roller should use foam, velor or cloth.

When applying the primer it is important to remember that with a strong surface wetting may damage the substrate.This is especially true putty.Therefore, soil deposition process on the surface is better to carry out in one move in one place.
Below is a short video in which the basic principles of the priming of the walls.
