DIY House Painting – 4 Things You Need to Know When Painting Interior Walls

Whether you’re painting a single wall or an entire room, the job at hand is relatively easy; however,  getting the desired finish is what many do-it-yourselfers can’t seem to achieve. In fact, there are a couple of things you need to carefully consider if you want your walls to have the perfect finish.

With that said, let’s take a look at four essential things you need to know before painting interior walls.


1. The Weather/Temperature Plays a Role in the Outcome


Humid days are the worst conditions to undertake a DIY house painting project. A scorching and humid day can cause paint to dry up too quickly which leads to speckling, visible overlapping and an uneven finish. Brushes/rollers will also dry up quickly which will require frequent cleaning before using them again (this is extremely troublesome to do).

Also, the water content in paint tends to evaporate faster than it should which, in turn, leads to cracks in the finish. This is why we suggest picking a cool day to paint your interior walls to avoid all the cons that come with painting in humid conditions.


2. Miscalculations When Buying Paint are Costly and Inconvenient


If you’re wondering how to buy just the right amount of paint, we’ve got your back! Most homeowners end up buying too much or too little paint which can be costly and inconvenient, respectively.

Speaking in approximate amounts, one gallon of paint is generally enough to cover 400 square feet of wall. If you’re planning on using two coats, two gallons of paint is advised. Bear in mind that rough or textured walls absorb more paint than smooth, finished walls and hence, may require an additional canister of paint.


3. Preparation of the Surface Must be Thorough


If your walls aren’t prepped thoroughly, nothing else will matter! The perfect paint finish is achieved when you sand, scrape and clean up any stains or adhesives on your walls before applying the primer/paint.

Double check the wall for any rough patches, dirt and peeling to ensure that it is ready to be painted. To clean sticky or dirty stains from your walls, use a mild solution of dish soap and water. Remember to let the wall to dry up completely before wiping it with a clean cloth to remove dust and then apply a primer or paint.


4. Overlapping a Dry Edge is a No-No!


Whether you’re using a roller or brush, you need to be somewhat quick in applying paint as it can start to dry in under a minute. While you may want your walls to dry up as quickly as possible, allowing the edge of a roll/stroke to dry up before going over it will leave visible, unsightly overlapping lines. The trick here is to paint the area beside it (overlap the edge of the paint) while it is still wet so that the color and finish merge properly.


So, if you’re planning to paint your interior walls as a do-it-yourself project, we strongly recommend you to follow the advice above for the desired outcome. If you are worried about the issue of your project, don’t fret! You can always ask for help from a professional painter for that perfect finish!
