- 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°-75°) 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.
- While there is no immediate danger from using spray sealers, as a precautionary measure a respirator should be used. This will also insure no escaping sealer fumes are breathed. If a spray booth is not used, a window should be opened to remove any fumes.
- Do not spray in drafty areas. Spraying outside is acceptable, taking into consideration the humidity and any wind while in use. Excessive wind can cause the spray to blow back into your face instead of onto your piece. The air temperature should be noted as temperatures of more than 85 degrees or less than 70 degrees will give poor results.
AC-516 Porcelain Mist spray gives the look and feel of fine porcelain. This product will deaden the glossiest of surfaces. It can be used over a fired glaze surface to imitate the appearance of porcelain bisque. This will allow you to decorate with stains on top of the fired glaze surface.
The application of Porcelain Mist spray should be done in several light coats with sufficient drying time in between. Insufficient drying time or insufficient shaking of the can may cause the colors underneath to appear cloudy or milky. This can also result from excessive moisture in the air or from the piece. Porcelain Mist spray should never be applied over Glitters or Metallics as they will dull the reflective surface of the color.
When Porcelain Mist spray is applied over fired gold it gives the appearance of Roman Gold and over Mother-of-Pearl it gives a subtle opalescence. If a piece has fired Gold Luster and you wish it to remain shiny after the stain decoration, apply AC-304 Liquid Mask to the desired areas to protect it from the spray. Apply two coats of Mask to give proper protection and ease of removal of the mask afterwards. Read the label for directions on using the masking agent as it pertains to the brush. Porcelain Mist spray is used on animals to give them that natural look after drybrushing.
AC-514 Matte Spray is somewhat glossy but not exceedingly so. 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.
AC-510 Gloss Spray is a shiny glossy surface. It gives the ware a nice polished shine. It works well with most techniques to provide a tough durable glossy surface. This spray will brighten and enliven your colors.
AC-512 True Gloss Spray provides the ultimate in shine. This spray is even shinier than Gloss Spray in appearance. For those pieces that need to resemble a fired glaze surface this is the perfect choice. The acrylic colors will appear bright and wet.
