In order to avoid the appearance of a white plaque on the masonry, the preservation of attractive appearance and durability facilities, you must comply with the rules of masonry:

It is recommended to use grout (cement PC 400-500) without additives. It is preferable to apply the cement made in the summer. To use sand and water containing no water-soluble salts. Apply "hard" solution, avoiding excessive dilution with water (the mobility solution should not be more than 7 mm). Not to add to the solution with additives. Use for masonry freshly prepared solution. To prevent the use of recessed seams. The maximum depth of the seam — to a depth of chamfer (no more than 3 mm deep into the masonry), see Fig. No. 1. Such seams recommend performing with special rassevat (see Fig.2). In the construction of masonry do not allow the ingress of mortar. In contact with the solution on stacked masonry — remove it with a dry brush or the next day, wipe the brush with water. Do not wipe the front wall in a burlap sack. Daily, after use, cover the walls with a waterproof material (roofing felt, film, etc.). Avoid freezing unfinished masonry throughout its entire thickness. In case of impossibility of construction of the roof before frosts — always hide the walls for the winter with roofing material to prevent water ingress into the voids of the bricks and becoming soaked joints in the masonry. Because of the glut of bricks with water, followed by repeated freezing and thawing is not excluded flaking and chipping partial crock individual bricks exposed to excessive glut of water.For the same reasons it is not recommended to use facial facing bricks for the erection of fences as a brick fence all round the year oversaturated with moisture and subjected to repeated freezing and thawing (in season more than 100 times), which drastically reduces its durability, causing cracking and delamination of the brick in the masonry fence. For fences it is recommended to use bricks with water absorption of 4-6%. To improve the durability of structures is recommended to treat the surface of masonry hydrophobic liquid. Gidrofobizatora impregnation is recommended to use the following sequence: a) before laying the front surface of ceramic bricks dip in gidrofobizatora liquid to the first row of voids; b) after completion of the work with spray coating hydrophobic liquid dry surface of masonry, until its complete saturation, with the obligatory blown seams.The seam of the masonry is characterized by the shape of its meniscus (the outer surface of the seam). Forming the meniscus, thereby sealing the outer portion of the seam, which improves the strength characteristics of the cement joint and thus increases the resistance seam precipitation. In addition, various forms of meniscus, by themselves, affect the emphasis on the texture of the masonry. Thus, the recessed seams (rounded concave and concave dvukratny), due to the play of shadows, favorably emphasize each brick, giving the masonry the maximum texture. Conversely flat and curved seams give the walls more uniform. Recommended joint thickness is 8 mm. Maximum 10-12 mm. the thicker the seam, the more conductivity has walls as the conductivity coefficient of the weld on the basis of cement mortar is much higher than the thermal conductivity of ceramic bricks. So, for example, on thickness of 12 mm resistance of heat conduction face brickwork decreases towards the walls with the seam width of 8 mm by approximately 1.5-2% (approximate thermal calculation). Meniscus seam formed with a special profile rassevat, with each bead type has its own pointing.
