To bring new life to an old kitchen without breaking the bank, consider covering your existing Corian counters with a new paint job. Countertops get a lot of wear, so they will take some extra care in finishing, but even considering drying time, the new look can be completed in just a few days.
Clean Corian counters thoroughly with ammonia and water and let dry, then sand lightly using an aluminum oxide medium grit sandpaper. Wipe off any sanding residue.
Cover inset cutting boards or trim with painter's tape. You may also want to tape the sides of appliances that butt up against the counter to protect them from accidental paint swipes.
Prime the countertop using an oil-based bonding primer, following the manufacturers instructions. Allow to dry for at least 24 hours.
Apply a thin, even layer of oil-based paint to countertops and allow to dry. Repeat until you have three to four layers of paint.
Add decorative touches such as stenciled patterns or contrasting trim if desired.
Seal with no less than three to four coats of non-yellowing floor urethane for a tough, durable finish. Choose satin or high gloss urethane and follow the manufacturer's instructions about drying between coats. Allow at least 24 hours to dry before using the counter.
