How To Polyurethane Kitchen Cabinets: A Step-By-Step Guide

Are you tired of looking at your dull and worn out kitchen cabinets? Polyurethane can give them a fresh new look, and protect them from scratches and wear. Here’s a step-by-step guide on how to polyurethane kitchen cabinets.

Step-by-Step Guide

Step 1: Preparation

Remove all cabinet doors and hardware. Clean the cabinets thoroughly with a degreaser, and let them dry completely. Sand the cabinets with a fine-grit sandpaper to remove any existing finish and create a rough surface for the polyurethane to adhere to. Use a tack cloth to remove any dust.

Step 2: Apply Polyurethane

Apply a thin coat of polyurethane with a brush or sprayer, starting with the cabinet frames and then moving on to the doors. Be sure to follow the manufacturer’s instructions, and apply in a well-ventilated area. Let the first coat dry completely before applying a second coat.

Step 3: Sand and Repeat

Once the second coat is dry, use a fine-grit sandpaper to lightly sand the cabinets. Apply a third coat of polyurethane, and repeat the sanding and applying process until you achieve the desired finish. Let the cabinets dry completely before reattaching hardware and doors.

Top 10 Tips and Ideas

Protect surrounding areas with plastic sheeting or drop cloths.
