Natural lacquer construction program: wall surface repair, processing, batch putty for exterior wall (2 times), distributing, textured paper, closed primer (1 times), natural lacquer (2 times) to cover coat (1 times), paying owners acceptance
A, wall construction requirements: in order to ensure the quality of construction, cement metope of general newly painted some in dry, sunny weather and aging time (half a month in the summer, spring, autumn and winter, a month or so), so that the wall pH value is less than or equal to 10, before the construction of metope moisture rate less than 10. Temperatures above 5 degrees Celsius, before the construction to completely remove the wall grease and attachments, in order to reach the construction requirements.
Two, basic level processing: for wall uneven place, No. 425 cement repair, the flat wall. For concrete or cement inside and outside the wall and brick wall, as well as asbestos cement board, wood, gypsum board, polyurethane foam board, etc.. At the bottom of the construction material base surface should be flat, clean, and has good strength, new wall should be action a month before construction, renovation of the old wall, first leveling base, remove loose, peeling and dust grease and other impurities before construction.
Third, primer: will clean the wall, uniform brush natural real stone closed primer 1, prevent the alkali of the wall is too strong, and enhance the adhesion of natural lacquer. Let the basic level to maintain consistent color, natural stone to prevent uneven color.
Four, the coating: the primer to dry for at least 3 hours after, uniformly spraying natural lacquer 2 degrees (at least 4 hours per time interval), three-dimensional size can regulate the caliber gun, in order to achieve a variety of three-dimensional effect, also can spear spray method or layer by layer spray method, but each spray method using amount of each are not identical, three-dimensional pattern is different.
Protection layer: to be coated completely dry, evenly spraying (brush) 1 lacquer finish, thickness not more than 70 microns, can not be less brush or brush leakage. The natural lacquer to not easy to accumulate dust and has certain self clean, effective prevent stonelike coating aging and enhance lacquer of waterproof function.
Six, the construction process of the construction process: natural stone
Seven, construction equipment and requirements:
(1) air compressor: power 5 or more, with plenty of gas, at least three trachea, can meet the construction of more than three people.
(2) under pot spray gun: 500ml, more than 1.3 mm caliber, capacity can not be too big, or too heavy, inconvenient operation, small caliber, the construction speed is slow, may delay the time limit for a project, not large area construction.
(3) lacquer spray gun, gun, guns, guns and other, according to different colors to select monochrome projector, dual color, multicolor with guns, gun, in order to adapt to the different construction technology, spewing more ideal effect.
(4) all nozzle caliber: 4mm, 5mm, 6mm, 8mm, and according to the requirements of a model selection of different nozzle, aperture is small, spraying effect is smooth and uniform, large caliber, spend a little more, concave convex sense is stronger.
Eight, construction technology index:
(1) spraying truestonepaint: selection of lacquer spray gun, air pressure control in 4-7 kg / cm2, the construction temperature above 10 degrees Celsius, thickness of about 2-3 mm, such as the need to apply two, three, is interval of 2 hours, dry for 24 hours before can be polished.
(2): use 400--600 sandpaper polished, smooth gently raised surface to sand stone. Note that force can not be too fierce, otherwise it will destroy the film, caused by the bottom of the loose, serious will result in poor adhesion, imitation stone paint off.Nine, for different objects of lacquer spraying spraying technology:
(1) brick shaped stonelike coating: first according to the requirements of designed brick shaped size and in primed walls with wooden box frame do brick shaped model, and then spray lacquer, lacquer has not yet been dry before taking undergrowth box can be.
(2) perpendicular to the surface of the painting: the circling method, distance 30cm-40cm, painted with radius of about 15cm horizontal circling, does not shake the spray gun, such spray speed and uniform, and easy to control, if using a row of a row of main reduplication spraying, the speed is slow, handing over place to control uniform, will influence appearance, coating defects.
(3) Roman column spraying: because it is cylindrical, so the "m" linear spraying, distance slightly far about 40cm, Lance must be vertical cylindrical spray, from top to bottom, sprayed side turn again on the other side, the steering angle of about 60 degrees is appropriate.
(4) square columns spray: square column angular, easily because of spray uneven blurred edges and corners, to spray coating is convenient, to a distance of about 50cm spraying edges and corners, spraying distance, fog flowers scattered open, large area and uniform, if the distance is too near, little attention has been paid to will be spraying thickness, uneven spray, angular lines appear not to come out, losing the overall appearance of the beauty of the original building.
(5) cylindrical small gourd spray: modern architecture with cylindrical small gourd decorative railings, mostly spray lacquer, due to small and exquisite, highly ornamental, of spraying process is much more detailed. Do the railing decoration of the gourd column, distance is too close, some places simply can not spray, so by the conventional spray method is unable to achieve the desired effect. Spray a small selection of nozzle, distance of about 40cm, fast casual spray lacquer, from top to bottom side to side to spray, can not face to face spraying, jitter of the spray gun, ordered around try to spray lacquer and brush flat brush lacquer, no spray to place can also brush slightly wipe on a layer of, and then spray powder spray again, must not be too thin or too thick, covered with brush marks can be, thin not to good protection effect, thick, covered with the beauty of the original line, cracks and other undesirable surface phenomenon may also occur.
Note:
1, large wall coating construction should be 1.5 square meters per case, and then by grid spraying.
2, the bottom paint can be used roller coating, brush or spray coating process. The main material of the spray coating should be according to the decoration design requirements, through the test spray to determine the material viscosity, nozzle diameter, air pressure and spray pipe size.
3, main floor paint spraying and color spray Xing operation personnel should be in groups of two, construction of a painting, a person be matched to ensure uniform spraying.
Ten, the construction quality acceptance criteria: natural stone paint spraying engineering quality standards
Notes:
Natural lacquer is the natural crushed stone and the high water soluble resin combination, sometimes stone color due to natural factors, a lighter deviation, so products and chart color will appear deviation, is a normal phenomenon. Don't spray work on rainy days or severe weather (5)..
