Different architectural modeling base hydraulic sand bags should pay attention to?

Water package of water type and package type sand coating application is more and more widely in the building exterior wall decoration. The vertical construction usually encountered in the construction. When encounter other surface structure ( Such as the Roman column, column, etc. ) 。 ) , these should be how to build? Cylindrical spraying methods: cylindrical spraying tool should choose small nozzle, shake gun as much as possible in the surrounding spraying water sand coating water and package, and then use the brush water bag water sand coating and water bag. If you meet not spray, you can also use the brush coating a layer of a little, then spray gun spray it again. Be careful not to use structure thickness is too thin or too thick. Three-dimensional spraying method: Roman column when meet this kind of working face, need to 'M' linear spraying method, about 40 cm from base. Vertical injection spray gun from top to bottom on the cylindrical surface. When spraying side, can be sprayed on the other side, spraying Angle of 60 degrees. Square column spraying method: because the square column angular, uneven spraying in the construction process can lead to fuzzy edges and corners, spraying distance of 50 centimeters, guarantees the construction of the whole original and beautiful. Planar construction spraying method: first, spraying groove part of the grid lines. Pay attention to evenly sprayed grooves. For really high, rectangular section must be vertical spraying. After spraying groove part, metope can spray. Spraying, pay attention to the uniform coating, keep the distance between the gun and guns, pay attention to the pressure gun, because the spraying effect is too thick, will appear at the bottom of the painting. The sand in the water after drying for the first time, in order to appear more vivid stone effect, can be the second spraying.
