Emulsioni paint is water-based paint, paint film performance is better than solvent-based coating.
Half of solvent-based coating of organic solvent by water instead of here, so the toxicity of organic solvents is basically solved through emulsioni paint.
then KeBao related the personnel of the service for you to solve the construction problems of emulsioni paint. The concrete construction points for attention are as follows:
one, the basic level processing
( 1) At the grass-roots level surface must be solid, level off, smooth, dry, clean, no pollution and big cracks; Adhesive mortar on the wall and debris should be clear in time, have obvious bulge of empty drum and beat should be cleared, concave part with the same as the surface composition of polymer putty or mucilage leveling for repair, and maintenance. Concrete wall room temperature curing period of 28 days, new plaster wall room temperature curing period for 14 days.
( 2) Metope USES 5 - frost area 10 oxalic acid aqueous solution. After 24 hours, metope top-down 2 -, wash with water More than 3 times, and maintain dry 3 days. Metope is less than 10% moisture content to painting.
( 3) Old metope renovation, remove dust, sand, become warped skin; There is oil, to remove the original coating, can't remove to use detergent to clean.
( 4) Putty used in facades twice, must have a certain strength, flexibility and resistance to water, and with strong grassroots binding. After the scraping, there shall not be pulverization, peeling or crack; The first line of the thickness of the putty should be controlled in 0. 5 - 1 mm, mainly through the embedded fill to fill wall defect. The second be bored with child should pay attention to leveling bedding face, scraping the thickness of 0. 5 mm, after drying with # 100 or # 120 sandpaper smooth and no scratches, surface dust to clean up.

( 1) Before painting, read product manual carefully, control moisture content is less than 10% at the grass-roots level, PH value is less than 9. 5; Construction temperature is greater than 10.
( 2) Tu, grassroots should besmear brushs alkali resistant seal primer, the purpose is to prevent water soluble substances from primary precipitation, promote grass-roots uniform absorbing coatings, enhance the durability of paint adhesion and coating, paint 10% saving 30%.
( 3) Before construction, should be fully mixing paint, make its uniform, no floating color or precipitation; Control construction viscosity of paint, so as to make it flow in the process of coating not or brush mark; Construction shall not be arbitrarily in the process of dilution water.
( 4) Choose light color or brunet wall paint, should choose the weatherability good priority pigments, such as iron oxide or phthalocyanine blue series.
( 5) Application of operation should be 'fixed' for the principle, namely determining area, dosage, construction section, brushing direction; Construction operation procedure should be first brush door, again according to the vertical, horizontal, vertical, procedures, uniform thickness. The thicker the coating, the more prone to float and shading.
( 6) Exterior besmear to brush the large area, seam line should be divided, wall Angle of Yin and Yang, or leader, of the same metope USES the same coating, each coating shall not be too thick, time interval shall not be less than 2 h. Each picture is in the direction of a painting, a picture to go to another direction. Ensure uniform coating, if the top-down no trace, color, line is clear, neat, straight.
( 7) Construction of exterior wall coating, it is necessary to understand and grasp the weather at any time, to prevent the rain of coating before drying, strong current, high effect of dust pollution.
decorate construction paint notice:
1. Coating operation considering the weather conditions, such as humidity above 80%, the coating surface condensation, should stop the work, this is the winter construction of a special point.
2, in order to do not pollute the surrounding environment, the construction should be keep out, also known as protective engineering.
3, color separation line, coating boundary should be clear in advance design intent, and
5. Paint coating weight should faithfully conform to the provisions of the dosage, and pay attention to the edges and the cavity, so as not to cause insufficient coating. Paint besmear to brush, brush again after the dry film thickness in 20 - Around 30 m, more than 75 um film thickness is more ideal. There is a requirement for long-term anti-corrosion and drug resistance for adornment, need to have 100 - 200 m thickness can play an effective role, so you need to choose the thicker coating or increase the number of coating.
6 should give full consideration to storage, coating must comply with the request of 'hereby, in order to avoid the paint is not bad, coating shall be kept in the cold, dark place.
