Many people like the look of marble but are on a budget that makes real marble unaffordable. Cultured marble features a combination of real marble and resin, which creates a realistic look but also makes the material weaker than pure marble. It is often used to make sinks, which receive heavy use and can crack. Rather than discarding a cracked cultured marble sink, repair it by following the steps below.
You will need:
• Silicone caulk
• Caulk gun with appropriate size tip
• Binding strap (type used to secure cargo to a truck bed)
• Tack cloth
• 2-part epoxy
• Disposable plastic spoon
• Disposable plastic bowl
Step 1: A superficial crack is usually easy to fix with a caulk gun and silicone caulk. Use a tip on the gun that will fit into the crack. Squeeze enough caulk into the crack to slightly overflow the crevice. Wet your finger and push the caulk into the crack, smoothing it in the process. Let the caulk settle for one hour and then remove the excess with a damp rag. Allow the sink to sit for a day before using it.
Step 2: A deeper crack will require use of a product that holds the weight of the marble. Follow the manufacturer instructions for mixing the 2-part epoxy with the plastic spoon in the plastic bowl. Work fast so the epoxy does not set prior to application. Pour the epoxy into the crack, filling it halfway.
Step 3: Use a binding strap to bring both sections of the sink together. Wrap this strap around your sink, connecting the strap at the bottom of the sink. Crank the strap until both parts of the sink join.
Step 4: Some epoxy will seep out from the top of your sink. Do not wipe this off. Instead, allow it to cure (refer to manufacturer instructions for curing time) and sand it with the sandpaper until it is flush with the sink surface. Remove debris with the tack cloth.
