The correct choice of paint will substantially increase the house’s aesthetic value. But if you truly want to know more about the difference between interior and exterior paint then this article can fulfill your need.
Overview: The Difference Between Interior and Exterior Paint
Any one of us wants to have a beautiful home. And paint can help you do that in an economical and effective way. But have you ever think about the difference between interior paint and exterior paint? It’s wrong to assume that you can use any paint you want since the needs are unique at each location of the house.
Don’t know if you had used the suitable paint or not? Well, you learn about the distinct features of each type of paint right here and right now.
What is the difference between interior and exterior paint? This question seems to be more important nowadays compare to 20 years ago when the paints are interchangeable. The environment, the expose of sunlight, the weather, ….these factors have made the choice of paint is not that simple as it looks like anymore.
Well lucky for you, this article will present you with useful knowledge about that.
The difference in ingredients
The pigment is what gives you a can of paint its original color. The organic pigment is mostly used in making interior paint. When being exposed directly to sunlight or the environment, organic pigment tends to shade fast. This will make you have to repaint the wall again and again in a very short time.
This is why you should never use interior paint on an exterior wall or somewhere directly expose to the environment.
This is the ingredient used to bind the pigment and everything else together. Exterior walls are expected to deal with the harsh and constant weather so the paint used on it must utilize a special binder. Namely, to keep the paint and the wall tightly stick together then prevent the forming of cracks and holes.
Base on that, it’s very ill-advised to use exterior paint on an interior wall. You won’t need such options in an enclosed space which can be said to be outright unnecessary.
Depend on regulations, the liquid of the interior paint must contain VOCs at the minimum level. VOCs, or Volatile Organic Compounds, are used as solvents ingredients in paint. They can vaporize base on the temperature and this may cause health problems if use indoor.
VOCs effect may range from short-term dizziness to long-term liver damage, depending on the exposure. Exterior paint doesn’t have to follow this requirement though since it’s in the open. Another reason why you should not use any paint you like.
It’s also good to know that VOCs did come with an advantage: superior resistance. To put it short, low–level VOCs paints have better endurance than zero VOC ones. So you may want to consider your option well. But in case that you want a little bit of both then it’s ok to pick low–level VOC paint.
The advance of technology makes the low–level VOCs standard of today the same as zero VOCs standard a decade ago.
As mention before, the exterior paint has to frontally face the atmosphere and the weather by itself. It’s only natural that it’s got many extra additives in its ingredient list. They will preserve the wall surface while ensuring paint integrity. But they don’t do as well as the interior paint when it comes to scratching and scuffing, also not very easy to clean and wipe.
Another reason why you should use the right stuff for the right place.
The difference in usage and behavior
• Aesthetic value
Both the interior paint and the exterior carry their own share of the house’s aesthetic value. But the exterior paint must be a durable layer to oppose the harshness of the outside space. This is why the exterior type is a bit rough and thick which makes it look not that good inside your house.
The color may last longer but it’s not really worth it, especially when you got a better option available.
The added resin in most of the exterior paints will cause a phenomenon called outgassing. Pretty much like the VOCs problem, it’s vital that this won’t happen indoor for safety reasons. The outgassing may last for 48 hrs in some cases but most will be a slow process over the years.
In addition to the moisture found in walls, it’s essential that you allow the walls with exterior paint to “breathe”, especially in brick walls.
Interior paint also encounters this issue but not in the same fashion. This makes it a good choice for indoor use. You still need to ensure adequate ventilation though, just to be on the safe s side. And no matter what kind of paint you use, a gas mask or face protection is advised.
Create maximum airflow while you paint the wall and keep it like that for a few hours after you are done.
Can we really use this paint in place of the other? or Can I mix interior and exterior paint?
Not that you can’t do this, it’s just generally unwise to do so. Each painting has been designed for specific requirements and to go against that is simply ill-efficient. There is a way to save you trouble deciding on a good paint and that is the hybrid paint. This kind of paint got the benefits of both exterior and exterior paint but there are trade-offs.
Hybrid stills are a fairly versatile paint and an appropriate option for indoor and outdoor walls. Go with this if you don’t waste too much time deciding what to pick.
