The basis of the surface for repair can be a variety of materials: concrete, wood, brick, plaster. They have different properties, because the adhesion with materials for decoration will be different. And in order to make it as durable as possible, it is necessary to use a primer - impregnation for walls that penetrates to a depth of 0.5-1 cm. In addition to improving adhesion, the primer has moisture-proof and anti-bacterial properties.
In stores you can find a large number of primers of deep penetration - you just need to choose the most suitable option.
Types of primers, their advantages and disadvantages

Tips for choosing a deep penetration primer
According to experts, the best primer is one that fully meets all requirements. When choosing a composition, a number of factors should be considered:
- Place of work - for internal or external processing. If you have to work with facades, you should choose frost-resistant impregnations - acrylic and silicate mixtures will do. When working indoors, it is necessary to choose odorless formulations, such as acrylic or latex. When working in a bath or other rooms with high humidity, you should choose antiseptic compositions.
- The material of the treated surface. For example, for concrete it is necessary to use compositions suitable for absorbing bases - alkyd or acrylic. For wood, it is better to choose oil impregnations with antiseptic effect, while working with bricks - anti-alkaline, for tile - those that have antifungal effect.
- Drying time of the composition. When carrying out interior work, it is important that the primer dries out faster, because it will have to be applied in at least two layers, and the long drying time will delay repair.
- Finish This factor should be taken into account. To find out which impregnation is suitable for wallpaper, tile, putty, study the manufacturer's instructions for this information. You can choose a universal composition.
- Cost and manufacturer. When choosing a primer for deep penetration, give preference to well-known manufacturers who have proven themselves to manufacture quality compounds.
