Necessary Base

Must arrange for the waterproofing of foundations, as well as check and if necessary repair waterproofing between base and wall construction to prevent the rise of groundwater. Without all of these activities, funds for facades, most likely will be spent inefficiently. After carrying out these activities the professional finishers can proceed to the selection of programs facade. At the same time it should take into account a number of factors. 1. The characteristics of the substrate (base). Necessary to evaluate its deformability and strength surface layer, the degree of absorbency, absorbency, pH of the pH, the presence of soluble salts, etc. For maintenance painting is important to ensure compatibility of the new material so that the facade was finished earlier.

2. The colorful cover should have the necessary flexibility to take flawless hydrothermal expansion and contraction of the base. 3. Necessary to estimate the total amount of moisture entering the wall panels from all possible sources. The colorful cover should have sufficient water vapor permeability to prevent moisture entering the wall and could easily evaporate. 4. Must take into account the biological activity base to determine the required fungicide (antifungal), bactericidal, algitsidnye (protivovodoroslevye) properties of the coating.

5. Permeability of the coating. For example, for limestone base coating must be permeable to CO2, not to interfere with the reaction of carbonation. On the contrary, F / B basis is desirable to protect from CO2 as one of the causes of corrosion. 6. Climatic conditions. For definitions such as frost there, he must take into account the solar activity, the nature of winter, etc. 7. The state of the air basin – marine, industrial, etc., pollution of the atmosphere. Further pro-finishers must identify the requirements for materials coatings that affect the quality and timing of finishing. These requirements include: – Processing Requirements (thixotropy, ease of application, hiding capacity, ensuring uniform film, drying time, etc.
