How to Fix a Cracked Stone Flower Planter


Planters with flowers, plants or herbs are used by homeowners to add color to a particular spot, both indoors and outdoors. Stone planters that are placed outside are susceptible to damage caused by natural elements or accidents from human error. These planters can crack with time, causing unsightly cuts, tears or cracks to appear that deteriorate their appearance. These cracks need immediate attention to prevent them from getting worse and possibly ruining the planter.

Step 1

Examine the planter to determine the location of the crack and both its tips. To do this, scrape the planter to remove visible dirt and plant debris. Mist any stubborn dirt particles lightly to loosen them and then wipe them with a terrycloth rag. Use a sponge to remove any dirt from the surface of the planter once the crack is visible, so both the tips are easily visible.

Step 2

Drill a hole at one end of the tip of the crack, spacing it 1/4 to 1/2 inch away. Repeat the process at the other end of the crack, drilling very slowly so the planter does not break. Also drill a hole in the center of the crack if it is very long. Use a masonry drill bit with a tip made from carbide, a hard metal that penetrates through stoneware easily. These holes are called relief holes and their purpose is to prevent the crack from spreading.

Step 3

Slip a thin piece of wood into the crack to pry it open. Line the inside of the crack with a thin layer of waterproof silicone caulk. Remove the wood piece.

Step 4

Insert a length of wire through the hole at the top of the crack, run it around the planter and insert it through the second hole. Cut excess wire off with wire cutters, and twist both the ends together inside the pot with pliers until the crack is held tightly and closes. Flatten the ends against the planter. Apply steady pressure when twisting the wire to prevent the planter from breaking.

Step 5

Follow manufacturer's instructions to allow the silicone to dry thoroughly. Remove the wire and remove excess silicone with a blade.
