Really stone paint have any requirements on metope at the grass-roots level?

Really stone paint structure is composed of different coating systems, the quality of the coating system directly determines the quality and the service life of really stone paint. Coating system is divided into four parts: basic layer, the main coating and paint, primer. As the basis of the coating system at the grassroots level is the most important link in coating construction. Unqualified base coating treatment can lead to serious problems, such as peeling coating, coating layer empty drum and frosting. Version really stone paint, therefore, brings us to today's really stone paint construction of standard basic requirements of metope. Hope to be able to help each person's life! 1. Strong. Qualified to grassroots must meet strong degree. Walls of the empty drum, delamination, cracking and spalling can affect the construction. Judgment at the grass-roots level is strong, can be combined with percussion, visual, scratches and so on the many kinds of detection methods, to ensure that at the grass-roots level and firm, conform to the standards of construction. 2. Flat and level. Leveling is an important step to ensure coating decorative effect. At the grass-roots level uneven affect coating final adornment effect, such as frosting. If the grass-roots flatness is poor, fill the rest also can increase the workload and material consumption. Pay attention to detail: Yin and Yang Angle is vertical, founder, facade is vertical, and so on. 3. Dry. Technically, moisture content should be 10%, at the grass roots level by a professional testing instrument. If the moisture content is exorbitant, grassroots will lead to loss of alkaline, coating film is slow, easy to cause drooping and expansion. Tiantai building materials expert proposal, general cement mortar in the case of maintaining good ventilation, summer days 14 and 28 days of winter water content to meet the requirements, in order to catch up with the time limit for a project, basic maintenance should not be ignored. 4. Neutral: usually use strong alkaline cement mortar construction, high alkaline base will lead to coating high alkalinity, discoloration, and even affect coating adhesion. Therefore, in order to prevent the phenomenon of high alkaline, alkaline ph should be neutral. In general, the alkaline ph value should be 9. 5. Clean. 。 Clean up at the grass-roots level surface to improve adhesion of the coating to ensure construction quality. Therefore, rust, debris, oil, silicone, in addition to requests and so on. Should be cleaned before construction at the grass-roots level surface to ensure that the grassroots clean. If primary quality not up to standard, the quality of coating will be not guaranteed. '?
