Cementing Ceramic Broken Pieces
Brand certain the pieces are clean using alcohol. If the item has been fixed earlier clean off any old adhesive, or the new adhesive may not bond properly. Instruction to remove old adhesives.

Filling, Sanding and Surface Preparation
Wipe all surfaces with a 91% alcohol to remove dust and paw oils prior to applying filler epoxy
Mix even parts of PC-11 epoxy filler. For ease of application, work in room temperature of 75 degrees F or warmer. We place the PC-xi in a small heater and keep it at 100 degrees F.
Employ sparse layer of filler while pushing in to fill up cracks and missing fragments
Allow filler epoxy to cure for 12-24 hours (or longer) at a temperature of 75 degrees F or warmer. We identify our filled projects in a 140 degrees F oven over dark.
Placing under a lamp is some other good selection to optimize hardness for meliorate sanding performance. Identify at to the lowest degree 12" away from repair detail to avoid overheating.
Use Dremel EZ lock sanding disc 120 grit for sanding.
Apply depression speed to avoid burn marks and apply light pressure. Go out the final 10% or so for sanding past hand.
Warning - wear protective eyewear
If Dremel is not available, sanding the whole job by paw (using dust 220 sandpaper) will take longer but will yield the same results
Repeat process on platter'south other side
Continue sanding by mitt using grit 220
Apply long strokes for authentic surface continuity
If upon inspection, missed cracks are found, echo the steps in a higher place for the selected areas
Use 91% alcohol for clean upwards
After the beginning round of sanding, a 2d finer filling is required using a pocket-size sepulcher tool
Same filler (PC-eleven) is used for second application
Mix well the epoxy filler two even parts
Inspect surface with UV calorie-free or a spotlight for whatsoever surface defects (cracks, pits, pumps, etc.)
For seamless surface fill the defects with PC-11 lightly
Wait for filler second layer to cure in a warm room (see more above) before sanding
Sand second layer by hand with long strokes using grit 220, and so grit 400 and finish with dust 3600. It may be necessary to apply a third or fourth layer if UV / light close inspection reveals more than surface defects
Wipe with alcohol for better paint bond
Painting and Glazing
Airbrush over the repair line and taper off for shine color integration to original background coat.
Painting over the repair line will erase painting details which will be replenished after
Wait a solar day or two for the acrylic paint to dry out well and apply thin layer of cold glaze to protect the applied the painted areas.
Use fine brushes to apply colors
For translucent effect, paint several coats of thinned paints
In this instance, apply black color last
Wait for painting to properly dry (a couple of days) and airbrush articulate glaze
A second layer of clear glaze may be required. Sand surface with a 3200 grit micro-mesh (later waiting a day or ii for 1st layer curing), wipe grit off and reapply cold glaze
