How To Paint Your Interior Walls

Step 1: You Will Need

To fix this problem you're going to need to pick up some supplies.
-Masking tape
-Paintbrushes
-Paint rollers
-primer
-paint
and finally
-plastic coverings for floor and furniture.

Step 2: Prepare the space.

If the walls have been subject to lots of grease and grime, you'll need to wash them first to help the paint stick. Also, patch any holes or gashes and everything before priming.
Move your furniture and cover it and your floors with plastic or old sheets.
Remove the plates from your light switches and electric outlets and cover with a piece of tape.
Tape over the edges of your trim with masking tape.

Step 3: It's Prime Time.

You will want to use primer, especially if your paint changes colors dramatically from what you currently have. Prime it again after it dries. Primer coats the surface, giving your paint a better chance to stick the first time, meaning you won't have to use as many coats.

Step 4: Paint the walls.

With a roller, paint large diagonal stripes like a “W,” then spread the paint out up and down. Do this in areas about 4 feet square, overlapping before each previous edge dries completely to smooth the seams.

Add extra coats of paint as needed.

Step 5: Detail

Using a paint brush, paint the corners, trim and other areas you cannot reach with the roller.

Step 6: Watch it Dry

If you find yourself caught in this step, now might be a good time to make sure you have lots of ventilation to provide fresh air to equalize the paint fumes. Perhaps you could use this time to make touch ups or clean up after yourself.
