Preparing for Interior Door Painting

Before you start painting a door inside, get everything you need. This includes the right paint – one that’s durable and has a nice finish. You’ll also need things like drop cloths, wood shims, a 2-inch brush, painter’s tape, a paint pail and liner, a small roller and cover, a utility knife, and maybe a tack cloth and a Pelican paint pail. Make sure to properly prepare the door. Run a tack cloth over it to clean off dust. Cover hardware like knobs and hinges with tape. Lay down drop cloths and use shims to stabilize the door while you paint.

Necessary Supplies

You’ll need some key things to paint a door right. Start with high-quality paint that has a strong, glossy finish. Add drop cloths to protect your area, wood shims to steady the door, a 2-inch brush, painter’s tape for precision, a paint pail with a liner, a small roller for even coats, and a utility knife for any cutting needs. Consider also a tack cloth and a Pelican paint pail for smoother preparation and painting.

Door Preparation

Good prep work makes your door look professional when it’s painted. First, use a tack cloth all over the door to remove dust. Then, tape up any hardware to keep it clean. Lay down drop cloths to catch spills and use wood shims to stop the door from moving. Fill in any door imperfections with wood filler and sand it down for a smooth finish. If your door had oil-based paint before, it needs a primer before using latex paint. New doors that are already primed don’t need the extra primer. Cleaning, taping, and making sure the door is steady are key steps for a great paint job.

Interior Door Painting Techniques

To paint a door that’s still on its frame, painting an attached door is the way to go. Start by painting the panels inside. Use a brush for those hard to reach spots. Then, a small roller is great for the flat parts.

Start from the top and work downwards. Paint the horizontal rails and then the vertical stiles. Watch out for any drips, especially near the frame.

Painting an Unattached Door

Painting an unattached door is simpler. Take the door off its hinges and lay it on sawhorses. This makes doing the edges easier. Use a helper for support.

To start, brush the edges. Keep the standard painting pattern. Paint one side, let it dry, then do the other side.

Painting Different Door Styles

Every door style has its painting different door styles method. Flat doors are easy with a roller. For painting panel doors, use a brush and work from inside out.

Doors with painting doors with glass or mirrors need special care. Use masking tape to protect them. Painting bi-fold doors needs patience. Open them slightly to paint, and be careful at the edges.
