Spray application of our elastomeric coatings is simple. Most porous or rough textured substrates require initial application with brush or roller for proper penetration; however, on smooth surfaces spray application is ideal.
To obtain best results choose the diameter of hose and gun consistent with maintaining maximum pressure at the tip. Larger diameter hoses produce less pressure loss as the Product is pumped through it. The least restriction in the gun will also assist in maintaining the required pressure for atomization at the tip.
It is generally preferable to maintain the spray nozzle perpendicularly to the surface. A pole extension of a few feet will make this easier.
Because of the exceptional high solids content of 1530, 1655 and 2010, an airless spray system must be capable of developing 3,000 PSI measured under static conditions at the pump Outlet, to properly atomize without dilution. When applying 1650 material, an airless spray system must have a static pressure capability of 2,500 PSI.
Tips in the range of .025 to .031 and a fan width ranging from 10 to 16 inches are most suitable for 1530, 1650, 1655, 2000 and 2010.
When using sprayed application for textured products, please contact Weather Barrier for application equipment.
