Brick primer - application and how to choose the right one
Is a primer solution required for wall surfaces, made of bricks? Some people believe that painting brick walls or applying plaster on it without priming, because such materials already perfectly fit the surface of the base to be treated, providing a high-quality level of adhesion to surfaces.
But this statement is correct not for all building-type mixtures, but only for primer additives that contain primer-varnishes, primer-paints or even primer-putties.
If there is no such element in the composition of the finishing material, then applied without preliminary plastering will soon begin to crack, and the paint and varnish material will peel off. So, let's take a closer look at the brick primer.
The use of priming mixtures when performing repair work has long been a mandatory requirement.
The fact is that all materials must adhere firmly and firmly to the base. For this purpose, a primer is used. But it is not always easy to figure out which primer is more suitable for the wall surface. A good composition will become an indispensable material for any repair process. Thanks to the use of such materials, the overall quality of finishing work is improved.
Moreover, the service life of the pasted wallpaper and, in general, all materials by means of which the surface will be processed, increases.
Consider the main functions that a primer composition for wall surfaces perform:
The quality of construction and finishing works will depend on the correctly selected primer, depending on the condition of the brick wall and further decorative design.
The wall priming suction will provide:
- Adhesion (adhesion) of the finishing material to the base surface.
- Strength (when using reinforcing mixtures with deep penetration), which is extremely important when strengthening crumbling or old walls.
- Water resistance - additional protection of bricks from atmospheric precipitation or in a room with a high level of humidity.
- Protection - primers with antiseptic additives reliably help prevent the development of fungal colonies and mold.
- Efficiency - after using primer mixtures, further consumption of paint and varnish material or tile glue will be much reduced.
- Finishing quality - on a primed wall made of bricks, the paint and varnish material will lie flat, the plaster will not crack, and the adhesive composition for the tile at moderate consumption will ensure reliable adhesion of the decorative tile to the base.
When choosing a primer for processing the wall surface, consider:
In addition, the chemical composition of the primer for plastering bricks should be taken into account:
They can be used before applying any topcoats.
They fit perfectly on any bricks that provide high-quality adhesion and protection from external conditions. Often, deep penetrating mineral-type mixtures are used to improve the strength properties of indoor and outdoor walls. They are non-toxic and also environmentally friendly. These primers can be used prior to any decoration type.
for work only on brick bases, it is recommended to take special primer solutions.
How to choose a primer composition - deep penetration or simple, and what is its active component, everyone must decide for himself when buying. If for some reason you find it difficult to choose, you should seek advice from a sales consultant in a construction market.
So that the wallpaper or tile is held fairly firmly, and the paint and varnish material and plaster do not cracked, it is required not only to select the required primer composition, but also to apply it to the surface of the walls in compliance with all technology.
Before starting priming, the base should be prepared:
Once the brick wall has been cleaned and properly prepared, priming can begin.
They can be carried out using the following devices:
Please note that both deep penetration primers and conventional primers are applied in a thin layer on a brick base, and left for a couple of hours to dry.
If necessary, the procedure should be repeated several times, achieving the required properties of the walls before applying a decorative type of finish.
Choosing a primer mixture in accordance with the base and finishing materials, and in full compliance with the priming technology, you can provide durable high-quality repairs.
