How do I prep and paint interior walls?

they tell you to wash walls but i just dust them and repair the holes ect. with a SPONGE if you sand and the walls are new it will sand the wall too smooth and leave a spot that looks different

First you need all the tools needed paint brush, rollers, pan for paint. I use inserts so you don't have to clean pan, drop cloth, paint, spackle, frog tape, second, wash walls base board etc. If you need to cover nail holes spackle , sand..third painting, do cutting in first all trim, then roller walls, may take 2 coats, lastly I do base board use frog tape make sure the paint is dry on walls before putting tape on...you can also use f.tape for ceiling so you don't get paint on it..good luck...I love to paint rooms..hope you take your time and enjoy it too..

Your local paint store is perfect for newbies. (I'm talking Sherwin Williams, Benjamin Moore, Miller) They have pros to help explain every step, and the supplies to set you up for success. I recommend waiting for a sale because it an be expensive to outfit yourself when first starting out.

Once you've got some confidence, you can go to the local hardware store to replenish for the next project.

Clean with a dry swiffer is my advice to add to Leisa's. It's great to keep the dust down.

My favorite brush for cutting in is this one because it's flexible in tight spots due to the short rubber handle:

I also like using a roller handle that extends and has a cushioned handle. I've only found it at Home Depot.

If you are messy, wear a cover on your hair. Lay down a tarp or drop cloth to protect furniture and floor. Take your time.

WASH your walls with TSP. Trust me, they are filthy. Paint won't last if the surface of anything you want to paint isn't squeaky clean. Easier to paint empty rooms but that isn't always possible. Cover with plastic sheeting and use drop cloths. Here are some very handy sites:

Even though it sounds like you are painting walls that have already been painted, you may still want to prime especially if you are trying to cover a darker color with a lighter color. A special primer (like Kilz) is definitely needed if you are trying to cover stains. Finally, primer is cheaper than good quality paint so you may save in the long run. Good luck!
