So you're finally ready to paint that room you've been talking about for months. It seems like you're finally ready to get started but don't know

exactly where you should begin. Well, have no fear I'm here to help you get through this. I'm going to give you some painting tips that

will help you to complete your interior painting project, and before you know it, you will be painting like a professional in no time.

Remove The Furniture

First, you'll need to clear the room of furniture and remove everything from the walls. If it's not possible to remove all the furniture from the space

then move everything away from the walls to the middle of the room. This will allow you to have easy access to the walls and trim.  

Cover Everything

As a general rule, I like to cover just about everything! When I'm doing residential painting I don't like to take any chances. If there will be furniture

in the middle of the room while you are painting, then cover your furniture. It's better to be safe than sorry, trust me it will prevent a lot of

aggravation later on (I'm speaking from experience). For covering furniture, I like to use plastic sheeting because it's cheap and it covers well.

A drop cloth will work as well, but I usually use a lot of drop cloths when doing exterior painting not interior. For interior painting projects I like to

use plastic sheeting. Remember, if you're going to paint your ceiling cover the floor completely. I can't stress this enough!  

Prep The Walls

Remove all the light switch covers. If your walls are dusty you can take a damp cloth and wipe the dust off the walls. If the walls are greasy then

you can take some soapy water and wipe the grease off the walls. Either way, this is a good way to clean your walls in preparation for painting.


Every professional painter will tell you that interior painting usually requires a lot of caulking. Gaps between the wall and trim must be sealed with

caulk. Caulk provides an airtight seal that acts as insulation, and it also makes the work look so much more professional 


Check your walls for nicks, dings and holes that need to be repaired. Patching is an important part of the interior painting process that shoild not be

ignored. Be patient and take your time to check your walls for holes that need to be patched. I personally recommend using Easy Sand 45 Joint

Compound for all patch repair work. "45" is what I like to use, it's a great product and it allows you to use only the amount that you need to do the

job. Just put some powder in a mud pan or paint pot, add water and mix with a putty knife. It's that simple!

Sand The Walls

After you patch, you need to sand the walls, especially the areas of the wall where you have patched. Never over sand, but sand the walls

smooth. Run your hand over the walls to feel for "snots" and "snags". These rough spots you can sand off easily until you feel a smooth surface.

Spot Prime

Spot priming is essential when prepping your walls for painting. Spot priming will prevent the patches from "flashing" or being visible after you

paint. "Flashing" occurs when patches are painted with only on coat, which is inssuficient to hide the outline of the patch. You can use a

brush to paint over the patches, but I prefer to use a small "whizz" roller (aka hot dog roller) because I don't like to leave brush strokes. So

whether you use a roller or a brush make sure you spot prime before you paint.

If you prepare your room by taking these steps before you start your residential painting project will come out right !
