AC-512, 514 Aerosol Spray Sealers

Spray sealers provide quick drying, smooth, durable, hard coatings for all acrylic and stained surfaces. The sealers give the colors brightness, enhancing the colors and providing varying degrees of glossiness. 

AC-512 True Gloss Spray provides the ultimate in gloss sprays. For those pieces that need to resemble a fired glaze surface this is the perfect choice. The acrylic colors will appear bright and wet.

AC-514 Matte Spray produces a satin sheen. This is the most preferred spray for all around use. Two light coats will give a pleasing shine to the finished piece. Three light coats make it a bit shinier. Too much can give a slightly yellow cast. Matte Spray is a good choice to use to set colors while working.

Application Recommendations

  • The piece should be dry before applying an aerosol spray sealer.
  • Shake the can well. This should be done for a minimum of two minutes to mix the ingredients well.
  • Hold can approximately 10-12 inches from the surface of the ware.
  • With the nozzle facing away from the piece press down to begin the flow of spray.  Gently wave the spray over your piece while dispensing the spray.  Face the spray away from your piece as you stop dispensing the spray.
  • Periodically shake to remix the ingredients in the can.
  • Make sure each coat is dry before applying the next.
  • The spray nozzle should be completely depressed when spraying. Not fully depressing the nozzle can cause the spray to falter. Keep your finger out of the spray as larger droplets can form and be transferred to the surface.
  • To insure that the can functions properly for the next usage, invert the can and depress the nozzle to clear the opening. This should take only a second or two. Depress the nozzle only until no spray escapes. You will hear air escaping, but will not see any spray being emitted.

Helpful Hints

  • Spray applied to wet acrylic can cause the color to bleed if applied too heavily.
  • For the final coating of sealer, allow the piece to dry a day or two as moisture can be trapped into the spray sealer.
  • The final sealing “coat” is two to three light coats of the desired spray.
  • A “set” coat can be applied with a sealer while work is in progress. Apply one very light coat; just enough to set the color for further decoration. Either Porcelain Mist or Matte Spray is preferred.
  • When spraying, the distance from the ware should be 10 to 12 inches. Refer to the label for any noted difference in this distance. Spraying from a greater distance can cause the tiny droplets of sealer to dry before they come into contact with the piece. Holding the can too close can cause runs, drips and discoloration in the final coating.
  • For best results, spray at room temperature (70° F-75° F) and do not spray in high humidity areas. The humidity in the air can be trapped in the layers of the sprayed surfaces producing a cloudy look and should be taken into consideration when using.
  • Use sprays only in a well-ventilated area. A spray booth should be designed with enough air draft to pull the overspray away from the user and large enough to keep it off other objects.
  • As a precautionary measure Mayco recommends the use of a NIOSH respirator. Make sure the room is proper ventilated.
