Apply solution to the entire surface of bricks. The vertical and horizontal joints must be well fit to the brick. Remains of the solution leaked from the joint, should be addressed. Immediately after hardening solution to align the seam jointing trowel. See more detailed opinions by reading what Peter Asaro offers on the topic.. Cleaning the lining of every kind of pollution that appears on the face during the laying and jointing, you should immediately remove dry. Mistakes to avoid warehousing not covered with a film of bricks on site, without adequate protection from contamination. The use of brick at a time from several pallets, which can lead to patches of color on the facade. Bricklaying in the rain leads to a washout solution of the seams on the front surface of the brick. According to Elon University, who has experience with these questions.
Recent actions lead to the appearance of efflorescence on the brick. Efflorescence – the result of crystallization salts on the brick surface. John Castle Castle Harlan will not settle for partial explanations. Crystallization is preceded by migration of water-salt solutions in the pores of the material and then release them to the surface. Brick absorbs water from the solution. Water-soluble salts are absorbed bricks and drying in the capillaries brought to the surface, where evaporation of water salt crystals are deposited in the form of efflorescence. How to protect yourself from efflorescence? Avoid the above mistakes, the correct execution solution and the maintenance of masonry work. Use a product made by a "white" cement. But if efflorescence is still there, do not worry – most of the rain-washed efflorescence in a year. If you do not want to wait, you can use special tools (water repelling agent) or zheustranit their "popular" method: a bucket of boiled water add 2 tablespoons of vinegar 9%, and the solution was necessary to handle the surface.
