Indoors, brick walls are painted for aesthetics or to keep the room dust-free. In the first case, the walls are sometimes specially dismantled down to the ordinary brick to achieve the naturalness and texture of real masonry in the interior.
This is done in eco-styles – Scandinavian, Danish or loft.
Sometimes in new premises, brickwork is not initially puttied in order to save on finishing materials – then the wall is painted to keep the room dust-free.
Walls made of ordinary brick must be covered with varnish or paint. This type of brick is not intended for cladding – it has a rough uneven surface for better adhesion to the mortar, and it dusts due to the high content of sand or cement in the composition. In addition, if the ordinary brick is not painted or at least covered with putty or masonry mixture (mortar), over time it will begin to crumble.
Facing brick is often used for finishing facades. It does not need painting: it is a durable material that is not afraid of the sun or rain. Modern facade bricks come in many colors, and the color can be selected at the stage of building the house. But if you decide to change the color, the facing brick can also be painted.
However, most often, houses with facades made of sand-lime bricks are painted. This type of brick absorbs moisture well, so painting is needed not only for beauty, but also to create an additional protective layer.
