How to Repair a Broken Cement Gargoyle

Gather up all broken pieces of the cement gargoyle and wash them thoroughly with warm water and liquid dish soap. Allow the pieces to air-dry for at least one hour in a warm place.

Fit the broken gargoyle together, figuring out where each piece goes. Remember this pattern so you know exactly where to place the pieces when bonding them. Set the largest intact piece on a work surface and lay the other pieces around it.

Mix mid-cure epoxy per the manufacturer's instructions. Apply the mixed epoxy to a broken side of one of the gargoyle pieces. Press the piece into place on the largest intact section of the gargoyle firmly and hold it there for one minute. Use a rag to clean up any excess epoxy that seeps out from between the pieces.

Repeat the process of adhering pieces to the gargoyle with epoxy until everything is back in place. If you have several small pieces, work with them last. You might need to use duct tape to hold pieces in place as you go. Allow the gargoyle to dry overnight or for about 10 hours.

Remove any duct tape from the gargoyle then blend the epoxy clay per the manufacturer's instructions. Begin filling in the cracks in the gargoyle with epoxy clay, smoothing it with your fingers to match the surface. If you are missing any pieces, recreate them directly onto the gargoyle with the epoxy clay. Allow the clay to dry for 24 hours.

Mix epoxy concrete, according to the manufacturer's instructions. Paint a thin layer of concrete over the entire gargoyle with a paintbrush. This will disguise the repairs and make the surface even. Alternatively, you can use cement paint to color the entire gargoyle. Allow the gargoyle to dry for 12 to 24 hours.

Paint a layer of cement sealant over the entire gargoyle to protect it from the weather if applicable. Allow the sealant to dry for at least 48 hours before placing the gargoyle outside.
