IMPORTANT: Ceramic restoration materials are not food safe, liquid or heat proof (over 190 caste F) and repaired items should non be used on cooking or food serving ware more...
To match placement of broken pieces so that gravity lone tin can keep proper alignment, fill a container, that is slightly larger than the piece you want to gear up with plastic pebbles, rice, or sand. This volition cradle and concord the repaired slice still and in place while it cures.
Where to get supplies
Make certain the pieces are clean using alcohol. If the item has been fixed before clean off whatsoever quondam adhesive, or the new adhesive may not bond properly. Instruction to remove old adhesives. Fill up a container, that is slightly larger than the piece you desire to gear up with plastic pebbles, rice, or sand. This will cradle and concur the repaired piece still and in identify while information technology cures.
Identify the larger broken part in the PVC pebbles / resin pellets (rice or sand) so that gravity will hold the top piece in place. Verify fit before applying adhesive.
Place even amounts of 5-minutes articulate epoxy on a paper or cardboard pad
Mix epoxy well with a pin tool, paper clip or a wooden stick.
Utilize epoxy mix to one side using a pintool or a wooden stick. Utilize only enough agglutinative to cover the border. Also little will leave gaps, resulting in a weak repair
Place broken piece over the epoxy. Important: You have just about 60-90 seconds from start of epoxy mixing to consummate the broken piece's permanent placement earlier the epoxy becomes mucilaginous and not workable
Quickly join the pieces together while applying light pressure to clasp actress epoxy out. Apply tweezers to utilise small pieces. You lot only accept about 60–xc seconds from start of epoxy mixing to placement before the epoxy becomes mucilaginous and unworkable. Do not wipe off the squeezed-off epoxy to avoid smearing. Expect at least twenty minutes earlier proceeding with the adjacent slice.
If your particular is broken into more than a couple of pieces, plan the zipper sequence to avoid being left with a final piece that cannot exist easily attached or fit in. Numbering the pieces after a dry out run is a skillful idea and will assist in the actual implementation. Let each joint cure earlier repairing the next one.
Verify that pieces tin stay steady during the cure period (let it cure at 75 degrees F or warmer)
If pieces do not concord well using gravity, use clay for additional support
Let the epoxy cure for 60 or more minutes before removing backlog cured epoxy with a blade
Bend blade for better access clearing unwanted cured epoxy. Warning - wear protective eyewear
Make clean surfaces with alcohol for proper filler bonding
What you will need for filling steps: ane. Two parts Epoxy filler PC-xi 2. Dremel EZ lock 120 grit disc iii. 220 grit sand paper 3. 400 grit sand paper iv. Rag 5. Mini Spatula 6. Paper pad to mix Epoxy on 7. Denatured or 91% Alcohol
Where to get supplies
Of import: Ceramic restoration materials are not food-safe, liquid or rut-proof (over 190 degrees F) and repaired items should non be used on cooking or nutrient serving ware more...
Wipe all surfaces with a 91% alcohol to remove grit and hand 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 pocket-size heater and keep it at 100 degrees F.
Apply thin layer of filler while pushing in to fill cracks and missing fragments
Allow filler epoxy to cure for 12 hours or more than at a temperature of 75 degrees F or warmer. We place our filled projects in a 140 degrees F oven over night.
Placing under a lamp is another good choice to optimize hardness for ameliorate sanding performance. Place at to the lowest degree 12" abroad from repair item to avoid overheating.
Use Dremel EZ lock sanding disc 120 dust for sanding Warning - wear protective eyewear
Use depression speed to avoid burn marks and apply lite pressure
If sanding past hand, start with 220 grit sandpaper and finish with 400 grit
If upon inspection, missed cracks are institute, repeat the steps above for the selected areas

Choosing your adhesive Specific kinds of adhesives are generally used to mend ceramics. We recommend clear, five minute setting ii-function epoxy. There are cases where a slower setting epoxy will work better. In lodge to choose the correct adhesive for a ceramic repair, you must kickoff identify the type of ceramic involved. Because an verbal fit is essential in repairing ceramics, you must accommodate the pieces precisely before the glue sets. Five-infinitesimal epoxies and instant glues might cure too fast and are not recommended if y'all demand longer time to match and adjust a precise fit. We use different adhesives for dissimilar applications. For the purposes of this tutorial, we recommend more commercially bachelor brands that are listed in our Where to Purchase Ceramic Repair Materials.

If the item has been fixed earlier, undo the quondam repair (run into how to remove old adhesive lesson), or the new agglutinative may not bail. Before handling the pieces, you may want to put on clean gloves to protect your easily from sharp edges. Make clean the pieces with alcohol.

Likewise fiddling will exit gaps, resulting in a weak repair; besides much will get in difficult to attain a tight joint. Warming up the ceramic pieces to 110-140 degrees F will thin the epoxy, creating a ameliorate fit, but will result in a faster cure time. Quickly join the pieces together while applying low-cal pressure squeezing actress glue out. Make full a container with plastic pebbles, rice, or sand which will hold the repaired slice in place while it cures. Use dirt as illustrated above to concur the pieces together if gravity alignment is not possible. Avoid shifting the pieces; small particles may come loose, ruining the repair. Any glue that oozes from the joint tin can be removed after using a razor blade. You may utilize tweezers to apply small pieces.
Fixing an particular with multiple breaks If you lot have a piece of pottery, ceramic or porcelain that is broken into more than a couple of pieces, programme the sequence in which you will adhere each slice to avoid existence left with a last piece that cannot be easily fastened.

A) Infrequent adhesion B) Will not shrink while curing C) Workable - tin can be drilled and sanded D) Paintable E) Water / oil proof F) Will tolerate broad temperature range without shrinking or expanding. We allow the filler epoxy cure at 140 degrees F enabling the filler to cure very hard which is optimal for sanding.
