Longer-nap roller covers are better for textured walls.

If you’re using an old roller, make sure it doesn’t have any dried paint on it that could cause lumps or bumps in your paint job.

On the flip side, too little paint can leave your paint job streaky and thin. Try to strike the balance in between too much and too little.

Professional painters can paint up and down in straight lines, but it’s a little bit tougher to do. If you’re a beginner, try a W or N pattern to start.

This is a little bit objective, and it might take some practice before you find the right pressure point for your paint job.

This is the easiest and best way to make sure you don’t get any streaks in your dried paint.

You can paint around the floor and ceiling first to make your paint job easier, or you can save it until the end.

Doing an entire wall at once ensures that you’ll keep a wet edge the whole time.

This is also called “back rolling,” and it’s a super important part of smoothing out your paint lines.

You can also sand in between coats to erase streak marks as they happen. Sanding also works well on paint drips or bubbles.
