Then comes sanding, followed by using an appropriate primer and paint. Let me share the complete method below to make things simpler.

Process of Painting a Hollow Core Door

Here is the method you can follow to paint a door with a hollow core:

1. Start by getting wood filler and a putty knife to fill any splintered/cracked areas. 

2. The layer of the wood filler should be a little higher than the surface of the food. 

3. Use a medium sandpaper to sand down the door to roughen up the surface. Do enough that the glossy surface of the door roughens up for the paint to adhere well.

4. Apply 1-2 coats of stain-blocking primer to keep the wood stains from bleeding through the paint.

5. Grab a semi-gloss paint in the colour of your preference to paint the door with a low nap roller for a smooth finish.

I had the unattractive hollow core doors with bogus natural wood. So I wasn’t sure if the paint would hold up on these, or what kind of paint to use. But then I figured out a decent way to paint the hollow core interior doors. Let me explain how to paint hollow interior doors.

How to paint hollow core interior doors?

• You have to remove the knobs, panels, and lock mechanism first, then put them in clearly designated containers. So you know where they belong when it's time to reinstall them.

• You can use painter's tape to cover each piece of hardware if you don't want to remove it.

• Covering the hardware with two coats of rubber cement is another option for masking it. When you're through painting, it should easily peel off.

• Fill any gaps in your doors with putty if they are in poor condition. Before you start, sand and clean them. You can use a suitable primer before painting to cover the fixed portions.

• If your door is unclean, wipe it with a scrubbing sponge soaked in TSP (trisodium phosphate). The grease and filth will be dissolved by TSP. The roughness of the scrub sponge functions as wet sanding, providing a surface for the new paint.

• Even if your door isn't particularly dirty, clean it with soap and water before rinsing it with clean water to eliminate any soap leftover.

• If you're intending to use latex to cover an oil-based paint, sand it softly and prime it with a good grippy primer first. 

• If you don't prime before painting, the paint will wipe right off before it dries. If you're not sure what kind of paint finish you have, sand and prime to be safe.

How to coat a hollow core door?

You can start with the frame and work your way up from the bottom, across the top, and down the other side. Paint the door last if you're painting the room's walls as well because it serves as an entrance and exit place. This will allow the freshly painted surface to cure without being disturbed.

After the first coat has dried, you can sand any areas that need to be sanded before applying the second coat. You have to remove any masking tape used to cover the knob and handles as soon as the second coat is applied.
