Airless paint sprayer to spray waterproofing acrylic coatings


A roof coating is a monolithic, fully adhered, fluid applied roofing membrane. It has elastic properties that allows it to stretch and return to their original shape without damage.

Typical roof coating dry film thickness vary from paint film thickness (plus or minus 3 dry mils) to more than 40 dry mils. This means a roof coating actually becomes the top layer of a composite roof membrane and underlying system. As such, the roof coating is the topmost layer of protection for the membrane, receiving the impact of sunlight (both infrared and ultraviolet (UV), rain, hail and physical damage.

Conservation Technology Acrylic Roof System is usually applied by roller or brush, but¬†the most cost efficient (especially for large jobs) is the high pressure airless sprayer. The waterproofing coating¬†will be¬†pumped from the bucket¬†to a pump where it is pressurized to 3000psi or more. The waterproofing coating is sprayed through an airless spray gun with a small orifice (usually 0.029- 0.040″).

When the pressurized coating comes out of the spray gun and is at atmospheric pressure, the pressure reduction causes the coating to atomize into small discrete droplets.Typically airless sprayer are characterized by their spray rate (eg. how many liters per minute) and their pressure. The number of spray guns that can be operated from the same unit are often listed. If you take the medium capacity pump

like DP6337ib sprayer pump ,   DP9600 hydraulic driving piston pump sprayer, it will support 2 guns (2 peoples spraying together),  we have also the bigger pump DP-GH6833 hydraulic airless paint sprayer, that model would support 3 or more guns for spraying


For successful roof coating spraying, the pump should have a delivery rate at 6L¬†per minute and a tip size of 0.030″. Pressure should be at least 2,000 psi. Larger units will allow for longer hose runs. This can be helpful on large jobs where the coating and the airless spray unit can be kept on the ground and only the hose and gun are actually on the roof. The above 3 models DP6337ib could support max.90 meters for the waterproofing acrylic paints horizonaly, or max.60 meters height.But the item DP9600 / GH6833 would support max.120m horizonally or 90m from height.

DP6337ib Airless sprayer is powered by brushless electric motor which is smart and intelligent.

DP9600 & DP-GH6833 is hydraulic pump powered by HONDA petrol engine which is more powerful.

While the electric motor may be less prone to the complexities associated with a gasoline engine, it may require a very long extension cord. There is an appreciable electrical current drop when the long extension cords are used. This can adversely affect the motor’s efficiency. By contrast the gasoline airless sprayer is fully self contained.

If the airless spray unit has a pump filter or gun filter, this should be removed. While the filter is needed for applying fine finishes and enamels, it merely increases the ‚Äúback pressure‚ÄĚ on the unit and lowers coating throughput.

Above three items are proven very reliable performance .
