How to prepare the walls of the house for painting?

Painting the facade, the walls of the house outside.
The quality and durability of painting the house outside to a great extent depends on the proper preparation of the wall surface. The base on which the paint will be applied must be dense, strong and primed. Preparation for painting old walls of the house To improve the condition of the base, as a rule, is always necessary before painting the old walls of the house. Before painting, the old wall must be cleaned from dust, mold, moss and easily exfoliating layers of old coatings. To do this, the wall is best washed with pressure washing, for example, automotive. Or you can wipe the entire surface of the wall with a stiff brush, but this option is more laborious. It is better to use both methods, after washing, to brush only the places of intense dirt.

Clusters of mold, moss after their removal must be treated with a liquid bioprotective drug. Otherwise, parts of these biological substances that will quickly germinate through a new paint may remain in the thickness of the wall covering. Then they repair the plastered surfaces, close up the cracks, places with peeling plaster. Old paint on the facade should not peel off and dust. Places with peeling paint are cleaned, primed and covered with an additional layer of new paint.

If the old paint is damaged in a large area, then it is better to remove it from the entire surface of the wall. To remove the old paint is convenient to use sandblaster.

How to determine the surface strength of the painted wall?

To do this, stick a sufficiently large piece of transparent stationery tape on the wall and after a minute, with a sharp movement, tear it off the wall. If, together with tape, the base pieces did not come off the wall, then such a wall can be primed and painted. At otherwise, the wall surface should be cleaned by removing the old paint.

Preparing for painting the facade of a new house
Plastered facades of new homes are quite durable. Preparing the facade for painting a new house outside is reduced to the following steps: It is imperative that you dry the freshly plastered facade for at least 30 to 60 days. The wall must be completely dry. Apply a primer to the wall of the house. Not plastered facades of silicate brick can be covered with a special colorless protective composition, or you can simply paint it with facade paint. In any case, the surface of the wall primed. Facades from a front ceramic brick usually do not paint. It is better to paint new walls of ordinary ceramic brick in the first two years, before the appearance of efflorescence on them.

Priming the walls of the house outside
The primer allows: to strengthen the dusting basis; increase adhesion (adhesion) of paint to the base; reduce water absorption of the coating; reduce the consumption of facade paint. Facade paint is easier to spread over primed
surface, and its consumption is markedly reduced. It is best to use a primer recommended by the manufacturer of the facade paint chosen for painting the house outside. The quality of painting the facade of the house can be improved if the primer is tinted to match the color of the facade paint. As a primer sometimes use facade paint diluted with water in a 1: 1 ratio. The primer is applied to the surface of the wall in the same manner as the paint. Before painting, the primer must be allowed to completely dry for at least a day.

How long does the paint dry?
Most facade paints dry out completely and create a durable coating 24 hours after application to the wall. The second layer of paint, as a rule, can be applied earlier, without waiting for complete drying. The first layer. Information on the length of the period through which the second layer of paint can be applied is contained on the paint package.

How to apply paint?
Facades are most often painted with a roller, brush or spray gun. The choice of instrument is determined by the consistency (viscosity) of the paint, the texture of the surface to be painted and the qualifications of the workers.

Paint the facade of the house outside with a brush and roller
Walls with a smooth surface painted with a brush or roller with a short nap. It is more convenient and faster to paint with a roller than with a brush, besides, less paint is consumed. When painting walls with textured surface or directly on the brick, use a wide brush with long bristles. Spray gun can paint the walls of any texture, both smooth and relief. Painting the house with an airbrush requires more skill and work experience from the artist. It is necessary to choose the viscosity of the paint, pick up the nozzles on the sprinkler apparatus. The practical skill of uniform paint application on the wall surface is also required. Painting the house with an airbrush is better to entrust the specialists. In the case of the use of special textured paints of high viscosity with a filler, in addition to the above tools, a spatula is also used for applying paint on the facade.

Before work, all non-painted parts of the facade (windows, doors, slopes, basement, blind area, etc.) are protected with plastic wrap. Painting work is performed in dry weather in the absence of strong wind. The ambient air temperature must be within the working range indicated on the exterior paint package. Before starting work, see the weather forecast. To paint the facade at a height, install scaffolding. It is not convenient and dangerous to paint the facade from the stairs. Coat of paint on one wall of the house put, without doing long breaks in work. If part of the wall is painted the next day, then there will be stains on the wall – places with a different shade of paint. The second coat of paint is applied after a break, not earlier than indicated by the manufacturer on the paint package. In order not to wash the roller or brush before each break in work, wrap the tool in a plastic bag – the paint will not dry.

Paint the walls of the house outside with exterior paint
Paint is distributed by moving the roller or brush in different directions alternately – vertically, horizontally and diagonally.

How to store paint?
Packing with paint should be protected from direct sunlight and frost. Paint should be stored at a temperature of +5 to +25 in tightly closed packaging. Paint that is stored in such conditions remains usable even after the expiration date printed on the package. If the paint has exfoliated during storage, mix it thoroughly with a mixer – with a nozzle on an electric drill, and the paint will again be usable.

How much does it cost to paint a house

Paint packaging always has ink consumption information. Usually indicate the specific consumption of facade paint – the number of liters (kg) that will need to be spent for painting 1 m2 of the facade in a single layer, l / m2. Sometimes on the front paint packages there is an inverse value of consumption – the surface area, which can be painted with 1 liter of paint, m2 / l.

Usually indicate the paint consumption in a certain interval, for example: consumption of 0.1 – 0.25 l / m2. Here, a smaller value of consumption is for smooth primed surfaces, and a large value is for rough, textured, not primed facades. On the websites of manufacturers and sellers of paints, you can find calculators to calculate the amount of selected paint, depending on the area of ​​the painted facade of the house, the number of layers and the roughness of the painted surface.

Facade paint is usually applied in two layers. For painting the house outside, the amount of paint is determined by multiplying the area to be painted surfaces – m2, specific consumption – l / m2, number of layers – 2, safety factor – 1.1. A safety factor of 10% is needed to avoid an unpleasant situation when there is not enough paint at the end of work.

How much does it cost to paint a house interior

Nothing is as refreshing as a new layer of paint. Whether you are painting yourself, or you hire a professional for this, if you know how to calculate the price for painting a square meter of a house, you can calculate the price and compare prices. By calculating the amount of paint needed per square meter, you can find out how much paint you should buy to do all the work.

Calculate the area of ​​painting, multiplying the length by the width of the room or rooms that you want to paint.

• Add individual amounts together.

Measure the height and width of each door and each window of the room that you are going to paint.

• Multiply the height by the width to get the area of ​​each door and each window.

• Fold the areas of each door and window to calculate the area that you will not need to paint.

• Subtract the total area of ​​the door and windows from the total area of ​​the room to get the area to be painted.

• The average window size is 1.5 square meters, and the door – 2 square meters. If the window or door is smaller, multiply the area by 0.8, and if the larger one, multiply by 1.5.

Decide whether you will paint the ceiling.

• Find the ceiling area by multiplying its two adjacent sides.

• The ceiling is usually spent on 85% more paint, in particular for acoustic ceilings.
