How do you paint your interior in 30 minutes?

The only time I have ever painted a room in 30 minutes was when it was totally empty. Prep (for me at least), always takes more time than the actual painting itself.

If you're referring to a room, I don't believe it's possible. A small closet...perhaps, but only is all taping and "cutting in" has been completed.

Impossible. Proper prep takes time. Primer needs time to dry. Finish paint needs time to dry.

If you are painting the inside of a small closet--then it can be done!

Rolling is pretty fast, but it's going to take time for the edges. It's possible to paint a room in a day though.

Well I found out how to do it in 30 minutes to an hour from The Idaho Painter. He has a lot of video’s of the different ways to paint a room in a short time. He’s from Garden City, Idaho. Check him out, you’ll find him on you tube.

Yep. Paint a room in 1 hour or less. Three guys. One tapes, one cuts in, one paints. 9" roller for small areas, 18 inch roller for the walls. Load up the roller with a lot of paint for one coat coverage. He doesn't have to pay for the paint. Works if you have the tools and a team.

A lot of other videos he's using other painters, pushing products. HEA and HVLP sprayers, 18 inch commercial rollers. naming specific paint.

Paint a window in three minutes, YES. Didn't mention how long it took to sand, caulk, plastic cover and tape the glass.

Spray paint a closet in a few minutes with a HEA sprayer.

As a former homebuilder/ remodeller Maintenance supervisor I can remove and replace a toilet in 20 minutes. How long would it take you.
