Primer filler walls before.

repair - troublesome and costly.I would like to make high-quality and inexpensive.But sometimes it happen?Economy - is good, but the repair is not done for a year.Therefore, the sequence of works it is necessary to adhere to.

primer filler walls before - though imperceptible at first glance the process, but very important.Do not execute it, you risk a month later regret their savings.Also wash the walls before the filler can save on the replacement of cladding materials.

Purpose primer

best way to save for a long time on the walls and ceiling decoration materials - is to use a special primer to increase adhesion.If the filler is not to produce a primer surface is coated with a plaster or tile adhesive over time begins to flake.Also, some types of primers are antiseptic and prevent the occurrence of mold.

To prevent trouble (cracking, loss and sagging putty layers of wallpaper), which often occur after putty rough surfaces will help to wash the walls before the filler.Photos help to understand

the features of primers and nuances of their application.

How to choose a primer for walls

primer to the walls of putty starts with choosing a suitable mixture.First, attention should be paid to the degree of surface porosity.Brick, concrete, and other materials have a different percentage of moisture absorption.This factor influences the adhesion strength to the surface finishing material of the wall.

For dense, low-porosity bases suitable primer with high adhesive properties.If the surface is loose, very porous, it is better to use the soil with a deep level of penetration.Universal tools used for the foundations of medium porosity.

Most primers designed for a specific type of substrate (manufacturers indicate them in the package) to achieve maximum effect.

Species primers

Primers there are many species with different properties for different surfaces.

acrylic primer (Universal) - suitable for most surfaces.Drying time is directly dependent on the humidity of the room does not exceed 4 hours.Acrylic solution is ideal for priming the walls before the filler.

Alkyd - only used for wood surfaces.You may not use together with putty.

glyptal primer - designed for finishing of wood and metal.Highly toxic, it is recommended to work only in well-ventilated rooms a respirator.

perhlorvinil solution - the most suitable for use in brick and concrete surfaces after shpatlevanija.Designed for outdoor use only.

phenolic primer as glyptal applied on wood and metal surfaces, where the depth of absorption is not important.Do not use before putty walls.

Polystyrene - is used for priming of wood and plastered, coated surfaces.It has a very toxic compound.

Polyvinyl acetate - for priming surfaces to be painted PVA paint.Time primer is completely dry - about 40 minutes.

Price category

In terms of price / quality primer can be divided into four main groups:

  • cheapest.They are used when the price is the dominant factor, but the quality is not particularly important.This applies to the low-budget construction, decoration of public non-residential buildings.
  • average price.Domestic producers, manufactures primer on the basis of imported components.
  • price above average.Putty and primer-known foreign manufacturers (widely represented in Russia).
  • high price.Elite foreign producers subject to additional special additives.Such material is made and sold under the order.The price may be higher value mixtures of the third group of at least several times.

    quality in most cases, is directly related to the price of a primer.But there are exceptions.There are options for a good primer for an affordable price, they are enough to have produced a quality primer to the walls of putty."Knauf" - range primers that are perfectly reinforce the base, quickly dry.In addition, absolutely non-toxic - are made from environmentally friendly components.


Preparing for the priming is not less important than the process of applying the mixture.

Before starting work, you need to take care to acquire all the necessary tools and materials.Application tools can be a roller, brush or sprayer.Also, when using the platen need a special container for easy operation.The number of coats is calculated based on the total area on which will be made to wash the walls before the filler.Consumption - about one liter per square 3-5.m (depending on the type of primer).

After that blanketed floor (if you do a partial repair).Suitable plastic film.Next, prepare the wall, remove the possible fastening elements are embedded potholes and cracks.Primer filler under the walls before the wallpaper requires careful removal of remnants of the old wallpaper to prevent delamination of fillings.

Description of work

Peeled wall prepared carefully handle a wet sponge to remove dust.Then pour into the prepared container primer and apply it on the wall.Apply the material to the wall is more convenient roller than with a brush: primer mix goes smoothly, while work is progressing quickly.

Movement first roller made from top to bottom, then left to right.Hard to reach places that lack roller coat with a brush.

Upon completion of waiting for drying the primer layer.Depending on its type, such as walls and humidity, this process may take from 3 to 15 hours.After drying the walls can start to putty.
