This is one of the types of work more prone to the DIYer, and at first blush it seems deceptively easy. I mean how hard can it be to slap a couple coats of paint on a wall? Some paint and a brush and you are good to go.
But not so fast. Before jumping into this there are a few things you should consider. Lets examine interior paintings for starters. You must first calculate the square footage of the rooms you are going to paint, including trim, to be able to determine the cost of the paint. Got that? Good. Next you need to determine the type of paint you are going to use, flat, semi-gloss, or glossy.
Once you have this down and the paint selected (don’t forget the primer), you need all the other stuff required for painting. You need brushes for walls and trim, rollers for walls and ceilings, drop cloths to keep the messy paint off floors and furniture, painters tape to tape up areas to don’t want to get paint on, a screw driver to remove all the wall plates and fixtures, water and wet and dry cloths to wipe mistakes and spills, a ladder, a container to pour the paint in, a couple saw horses to lay things on like trim strips and doors that you are going to paint. And some old clothes you don’t mind ruining.
Now you are ready to go. First pick a room. In painting, the prep work usually takes at least half the time. Ideally you can remove the trim before you paint it. Put it across the saw horses and get it all painted and put it aside to dry. Then start with the ceilings and roll on the ceiling paint, taping the walls first. Let it dry. Then paint the walls. When everything is dry put the trim and fixtures back up and voila! You have a beautiful new room! Then move to the next room.
