Before spraying, the spray gun and high pressure water mist, the construction surface clean of debris.

　　2. Control the spray gun and the distance between the construction surface, generally in a 1-1.5 m

　　3. According to the construction of the diversion valve at the end of the gun, strictly control the good water added. Add water will cause the ejected material too thin, poor adhesion force and collapse. Add water starts to cause the springback amount increases and waste of raw materials. Therefore, control the water content is a key in the spraying construction.

　　4. The spraying direction should be perpendicular to the surface, and spray gun mouth constantly do a spiral movement, partition spray, spray to the design thickness at a time.

　　5. The thickness of construction control is in the anchoring all buried after spray paint have not reached the initial setting, use the single 3 mm metal probe (or welding electrode) inserted after spraying the construction surface of its thickness measurement. If did not meet can continue the construction surface spray and the thickness of the has been achieved so far.

　　6. This is required for a large spray construction joints.

　　7. Spraying after completion of construction to achieve initial setting, do flat with spraying the surface of the parts.

　　8. Construction personnel in the process of construction, good wear labor protection articles, especially good to wear protective goggles, spraying parts high erection of scaffolding, construction should fasten your seat belt.
