HOW TO GET THE BEST INSYNC SPRAY GLAZE RESULTS:
1. SHAKE CAN VIGOROUSLY!
- Listen for mixing ball to rattle/move freely inside can.
- Rotate can slightly to change arc of internal mixing ball.
- Ensure specified nozzle tip is utilized and clear of residue.
2. PREPARE RESTORATION(S) AS CUSTOMARY FOR STAINING AND GLAZING
- Always spray on restorations that are dried and cooled to room temperature
- NEVER spray on heated restoration(s) as it causes the spray to” flash-dry” with little or no adhesion
- Shake can often to keep a homogenous mixture of Glaze
3. SIMULTANEOUSLY SPRAY GLAZE ALL UNITS
- Units can be sprayed singly or in multiples on sagger tray
- Peg putty can be priceless; no handling of restoration(s) is required once sprayed
- Rotate the restoration(s) while spraying to ensure even and accurate coat (some labs like to use a ‘Lazy Susan’)
4. DISTANCE FROM RESTORATION SHOULD BE APPROXIMATELY 3-5 INCHES
- Spraying too close results in sheeting or running of spray - “WET” appearance
- Spraying too far away creates a surface that resembles a macro powder build-up – “POWDERY” appearance; glazes to an undesirable textured surface (mottled, pebble-grain like).
- Distance is also a function of can contents: pressure, propellant and glaze material
5. SPRAY ANGULATION
- Spray perpendicular to the surface you are spraying as angulation will decrease spray effectiveness
- It is customary to have to apply 2-3 coats for adequate coverage before firing. Technique will vary the amount of coats, but 3 thin coats is usually 100%
- Under pontics can be sprayed by placing dies in adjacent teeth and spraying first. Dried spray easily can be brushed off any dies afterwards
- Be smart! Wear protective equipment such as a properly fitted respirator and have adequate ventilation.
- Taking 2 or more glaze firings: Glaze is not applied thick enough. Remember, a single pass/coat is very thin, so it usually takes 2-3 coats.
- Has ‘satin’ appearance on zirconia or pressables: Insufficient amount of glaze, needs another application + firing. Sometimes it takes 5-10C more to mature the glaze in certain situations.
- Surface of glaze seems pock-marked, irregular: Glaze sprayed too far away from restoration and surface is dry and lumpy, which fires to an uneven surface.
- Glaze is easily disturbed if touched prior to firing: Glaze should not be touched prior to firing due to its delicacy, thus peg-putty and sagger pegs prior to spraying is helpful.
