04 Setting up your airless sprayer

  • Make sure your airless sprayer has fresh seals. Ceramic particles are hard on seals and accelerate wear on already worn seals. If you have used your sprayer with solvent-based systems, we recommend a fresh seal kit prior to use of our product. Use leather seals if possible.
  • Be sure to purge airless sprayer with 15-20 gallons of water and circulate prior to placing pickup nozzle into product. Pull the orifice nozzle out of gun or remove gun to bleed any trash or unwanted items and cover intake tube with a mesh to prevent intake.
  • Prime sprayer with product by removing spray nozzle orifice to insure that all trash is removed from system. This is especially important if sprayer is used often and lines are not new.
  • In confined spaces, use ventilation fans to help evaporate moisture when spraying the coating as humidity will increase as the coating dries. This rise in humidity will lengthen the dry time. Air movement will greatly reduce drying time.
  • In hot, extremely dry climates (very low humidity conditions), lighter coats of 12 mils WFT (DFT 0.25mm) may be appropriate versus 24 mils WFT (0.5mm DFT) if you notice the top layer of the coating drying first and preventing the lower layers from evacuating moisture and drying properly.
  • In colder climates, spray a light 5-10 mil (0.25mm) coat initially and let it tack dry. This will help to deter sliding of product due to excessive thickness initially. This will also expedite dry times.
  • Spray more light coats as opposed to one heavy one in colder or in extremely dry climates. Work smart and think out strategy prior to spraying. Spray areas that are hard to reach prior to bulk of application. Use ladders and scaffolding if needed.
  • If product is found in undesired space or area, clean immediately via water and scrubbing method.
  • If product slides or blobs occur, smooth out with brush or let dry thoroughly prior to sanding smooth removal via wire wheel or scraping.
  • If spraying more than one coat, tinting can be used to differentiate coats. Standard acrylic tint can be used and is found at most paint supply houses. A good method is to use a hopper system (see Hopper system). Mix one ounce of black tint (will tint the coating gray) per five-gallon pail. Pour the tint into the bucket after the coating has been mixed. Stir the tint into the coating briefly. Periodically mix the hopper with the paddle. By using this method, a consistent color will emerge. DO NOT TINT THE FIRST COAT! It is important to keep the first coat white, as it will help differentiate the substrate and the insulating coating.
