Natural really stone paint construction procedures: wall surface repair, processing to batch of exterior wall putty (2 times), line, stick crepe paper - sealer (1) - natural really stone paint (2 times) to finish (1) to pay the owner acceptance

A, metope construction requirements: in order to guarantee the construction quality, usually a freshly painted cement metope must be in a dry, sunny weather, aging time (half a month in summer, spring, autumn and winter a month or so), make the wall body PH 10 or less, metope moisture content is less than 10 before construction. Temperature 5 ℃ above, to thoroughly remove oil and attachments metope, before construction to the construction requirements.

Second, the basic level processing: for wall uneven places, use 425 # cement to repair, so that the wall is flat and level. For external walls or cement concrete and brick wall, and asbestos cement board, board, gypsum board, polyurethane foam board and so on. Construction at the grass-roots level of substrate surface should be smooth, clean, and has good strength, new wall should work for a month, before the construction, renovation, the old wall to leveling at the grass-roots level, to remove loose, spalling surface impurities such as dust and oil dirties rear can construction.

Three, coat: after clean, metope even brush natural true stone seal coat 1, prevent metope is too alkaline, enhance the natural really stone paint adhesion. At the grass-roots level to maintain consistent color, prevent natural inequality really stone paint color.

Four, in besmear: wait for at least 3 hours after the primer and dry, evenly spray natural really stone paint 2 degrees (each time interval at least 4 hours), three-dimensional size adjustable spray gun caliber, in order to achieve a variety of different stereo effect, can also double gun spray method and spray method step by step, but the dosage of each spray method each are not identical, stereoscopic pattern are also different.

Five, the protective layer: stay in the besmear after completely dry, evenly spray (brush) 1 way really stone paint finish, thickness is no more than 70 microns, cannot little brush or brush. To natural true stone lacquer is not easy to accumulate dust and have certain self-cleaning function, prevent aging really stone paint and enhanced really stone paint waterproof function.

Six, construction process, the construction process of natural really stone paint

Seven, construction equipment and requirements:

(1) air compressor: more than five horse power, gas is enough, take at least three root trachea, can satisfy the three or more persons at the same time the construction.

(2) under the pot of spray gun: capacity of 500 ml, diameter 1.3 mm above, capacity cannot too big, otherwise is too heavy, inconvenient operation, small caliber, construction speed is slow, may delay the time limit for a project, not large area construction.

(3) really stone paint spray gun: points single gun, double guns, three guns, etc., according to the different design and color to choose monochrome single gun, double color, multicolor with double guns, three guns, in order to adapt to different construction technology, spewing more ideal result.

(4) all kinds of diameter nozzle: 4 mm, 5 mm, 6 mm, 8 mm, etc., according to the requirement of the template choose different nozzles, the smaller the diameter, the greater the spraying effect smooth uniform, spend diameter is, the greater the concavo-convex feeling stronger.

Eight, the construction technical indicators:

(1) spraying really stone paint: choose really stone paint spray gun, air pressure control in 4-7 kg/cm2, construction of more than 10 degrees Celsius temperature, thickness of about 2 to 3 mm, if you want to apply two, three, 2 hours, dry rear can finish 24 hours a day.

(2) grinding: using 400-600 mesh sandpaper, gently wipe the sand flat really stone paint surface bulge. Pay attention to Hard not too strong, or you will destroy paint film, caused by loose bottom, serious will cause poor adhesion, really stone paint falls off.

Nine, with different spraying object really stone paint spraying technology:

Really stone paint: (1) the bricks to design good brick shape dimension as required, and then in the metope besmear good primer with wooden frame Frame model make bricks, spray on really stone paint again, in the really stone paint is not dry before remove the wooden frame.

(2) vertical spraying: using the method of guoquan, distance 30 cm -- 40 cm, about 15 cm in radius horizontal spray guoquan, not shake up and down when the spray gun, spray so fast and uniform, and easy to control, if the rows of the main type of overlapping spraying, slow speed, uniform and junction difficult control, will affect the appearance, cause coating defect.

(3) the Roman column spraying: because of its is cylindrical, so the "M" is the linear spraying, about 40 cm is a little far, vertical cylinder spray, spray gun to top-down, gush to good side to the other side, it is advisable to steering Angle is about 60 degrees.

Square column spraying (4) : angular square column, it is easy to make fuzzy edges and corners, by spraying uneven to spray coating is convenient, the distance of about 50 cm spraying edges, the spray at a distance, the fog flower open, the area is large and even, if the distance is too close, can spray do not pay attention to a bit thick, uneven spray, the angular line showed not to come out, lost the original building the overall appearance of aesthetic feeling.

(5) cylindrical small gourd spraying: modern architecture using cylindrical small gourd railing decoration, usually demand really stone paint spray, due to the small and exquisite, have adornment sex extremely, the spraying process of them are much more careful. Do railing column decorated gourd, too close, some places cannot front spraying, so according to the conventional spray method is unable to achieve the ideal effect. Choose small nozzle spray, about 40 cm distance, fast really stone paint spraying, from top to bottom side to side to spray, not positive coating, with the method of the jitter spray gun, it try to spray around really stone paint, brush with wool and then really stone paint, no spray to brush can also be used on a slightly, the spray gun powder spraying again, cannot too thin, not too thick, brush marks cover can, thin can't have very good protection effect, thick, covered the original lines, might as well as the crack surface phenomenon.
