## How to Refinish a Fiberglass Kitchen Sink
### Materials You’ll Need
– Fiberglass repair kit
– Sandpaper (120-grit, 220-grit)
– Orbital sander or sanding block
– Acetone or denatured alcohol
– Clean cloths
– Mixing cups and sticks
– Gloves
– Protective eyewear
– Respirator
### Step 1: Clean the Sink
Thoroughly clean the sink with acetone or denatured alcohol to remove any dirt, grease, or other contaminants. Wipe the sink dry with a clean cloth.
### Step 2: Sand the Sink
Sand the entire surface of the sink with 120-grit sandpaper. This will remove any imperfections or roughness. Use an orbital sander or sanding block for best results.
### Step 3: Apply the Fiberglass Resin
Mix the fiberglass resin according to the manufacturer’s instructions. Apply a thin layer of the resin to the sanded surface of the sink. Use a brush or roller to apply the resin. Allow the resin to dry for the recommended time specified by the manufacturer.
### Step 4: Apply the Fiberglass Mat
Cut a piece of fiberglass mat to the size of the sink. Place the fiberglass mat on top of the dried resin and smooth out any wrinkles. Apply a second layer of resin over the fiberglass mat. Allow the resin to dry for the recommended time specified by the manufacturer.
### Step 5: Sand the Surface
Once the resin is dry, sand the surface with 220-grit sandpaper. This will smooth out the surface and remove any imperfections. Use an orbital sander or sanding block for best results.
### Step 6: Apply the Gelcoat
Mix the gelcoat according to the manufacturer’s instructions. Apply a thin layer of the gelcoat to the sanded surface of the sink. Use a brush or roller to apply the gelcoat. Allow the gelcoat to dry for the recommended time specified by the manufacturer.
### Step 7: Sand and Polish the Surface
Once the gelcoat is dry, sand the surface with 120-grit sandpaper. This will remove any imperfections or roughness. Use an orbital sander or sanding block for best results.
Polish the surface with a rubbing compound and a soft cloth. This will bring out the shine and protect the surface.
### Step 8: Final Cleaning
Wipe the sink down with a clean cloth to remove any dust or debris.
Your fiberglass kitchen sink is now refinished and ready to use.
