What Is the Difference Between Interior and Exterior Paint?
Architectural paints are the most basic building equipment material, providing the aesthetics and protection of the building.
However, different types of paint are used for the interior and exterior of a building.
Interior and exterior paints are specially designed to protect the building from negative external influences.
So why is the color used in a building divided into two parts: interior and exterior, what is the difference between interior and exterior colors?
Before answering these questions, let’s take a closer look at paints and then at the raw materials for interior and exterior paints.In this way we can make the answer to the question what is the difference between interior and exterior colors more understandable.
water-based paints are the preferred household paints.
These paint types consist of water, binder, filler, pigment and additives.
The types and proportions of these substances vary depending on the properties of the paint.
colors are divided into application areas such as industrial type, marine type, wood color, metal color.When it comes to home paint, there are two types of paint: interior paint and exterior paint.
Users mainly try to choose the color that offers the best performance and aesthetics among the brands, colors and varieties.
They are therefore looking for answers to questions such as which color is best for indoors and which is best for outdoors.
The answer depends on the application and the cost of the paint.
Basically, a paint should offer good opacity and long-term protection.Undoubtedly, the aesthetic aspect and the cost are also important.
Interior paints are colors used inside buildings, in spaces such as bedrooms, hallways, offices, bathrooms and kitchens.
The basic characteristics of the paints used for interior walls are good coverage, the absence of pollutants and the aesthetic aspect.
Properties such as resistance to dirt, gloss and clean ability can also be expected from an interior paint, depending on the user’s requirements.
Whereas interior paints used to contain solvents, we now use water-based products.
Because the solvent releases many harmful gases during and after use. Since the carrier phase of water-based paint is water, the water it contains evaporates as the paint dries, so it has no harmful effects on human health.
If you wish, for a better understanding of what is the difference between interior and exterior paints, you can read the articles that we, as construction chemistry specialists, have detailed below in the table of contents.
What Is The Best Interior Paint?
Paint manufacturers have divided the types of paint according to the area of application, e.g. B.
interior paints, exterior paints, wood paints, metallic paints.
These classifications are based on the properties and content of the paint.
The prices of the paintings are also fixed accordingly.
When selecting an interior color, the user makes a choice based on the color and luster of the paint.
Interior colors differ in their degree of gloss, for example high-gloss, semi-gloss and matt. Since the kitchen is a more used part than other rooms in the house and is more likely to get dirty, a more specific color may be preferable here.
Choosing a washable or stain-resistant kitchen paint ensures long-term use.
In addition, choosing a paint with 0% VOC and using a washable paint in children’s rooms will extend the life of the paint.
How to Paint Interior Walls?
You can paint your house yourself without the help of a professional.
The steps for this are quite simple, but for long-term use, these steps should be followed carefully.
First of all, the surface to which the paint will be applied must be well prepared.
Old paint should be sanded off and repaired if there are cracks or holes.
After repairing surface defects and sanding the paint, the surface should be vacuumed and treated with a suitable primer. After the primer has dried, the paint can be applied.
Before using the paint, read the instructions on the packaging and take appropriate measures.
Water-based paints do not need to be thinned.
Once diluted with water, the paint could lose its opacity and cause flow problems as its viscosity would decrease.
How Long for Interior Paint to Dry?
In addition to the advantages of water-based paints, such as B.
the absence of harmful substances, ease of use, the wide range of colors compared to solvent-based paints, the drying time is also very short.
Water-based paints are available for the second coat within 2-3 hours depending on ambient temperature, time of year and weather conditions.
It takes 5 to 7 days for the paint to dry completely and reach its final properties.
Interior wall paint can be dry and ready to use in 1 day.
However, we must not forget that it takes an average of 7 days for the paint to reach its final properties and during this time it must be protected.
How Often Should You Paint Your House Interior?
Parents rooms are less used and dirty rooms.
Therefore, the need to change color here is usually caused by a desire to change color or pattern.
In such rooms, color renewal can be carried out from 5 to 7 years.
In children’s rooms, on the other hand, the surfaces are more heavily used and get dirty.In such rooms, color renewal can take 2-4 years.
Because the kitchen is a busy space and exposed to contaminants such as oil and leftover food, the paint on the walls can be renewed in 2-4 years.
As can be seen, the times when the interior facades need to be repainted vary depending on the conditions of use and the type of parts.
In general, it takes 5 to 7 years to redecorate a house.
What Is The Best Exterior Paint?
In addition to the aesthetic aspect, resistance to external influences is also important for facade paints.
The exterior paint must be light, dirt and weather resistant.
facade paints can also be water-based.
In addition, acrylic, silicone and granular paints can also be options.
Silicone paints are dirt-repellent, so they hold dirt less than acrylic paints.Grainy colors create a textured image due to the ingredients.
Here too, as in the interior, the choice can be made according to the aesthetic aspect desired by the user.
Unlike interior paints, exterior paints require professional work.
However, you can paint small parts of the house yourself, such as the balcony, since there will be relatively less rain.
When it comes to painting, the same rules apply as for interior use.In other words, the application surface must be properly prepared and the application carried out according to the paint’s instructions for use.
Textured, granular or mosaic stone colors can also be used outdoors.
These colors contain ingredients that create a textured effect.
Applications are often performed with implements such as a trowel.
How Long Does Exterior Paint Need to Dry Before Rain?
The processing time for the second coat of facade paint is usually 2 to 3 hours.
It can be applied 6 to 7 hours before rain during rainy seasons.
It is also recommended to wait at least 1 day after rain before applying.
Application on a damp surface causes blistering, poor adhesion of the paint to the surface and loss of performance.
For exterior paints, remember that the paint will reach its final hardness and strength in 5-7 days.Therefore, days with no risk of rain and warmer weather should be preferred for outdoor renovations.
Can the Exterior Paint Be Applied to the Interior Wall?
If desired, the color used on the outside can also be used on the inside.
However, the paint used indoors is not suitable for outdoor use.
These paints are more resistant to external influences.
They are insensitive to rain and do not fade.
Based on these properties, it contains binders and additives with higher performance parameters.
Therefore, their prices are higher than interior paints.
Because of this, using the paint used on the exterior wall for the interior increases the cost.
mosaic stone colors with a textured effect can also be used on exterior facades.
These colors create different aesthetic attitudes on the applied facade.If desired, these colors can also be used on interior walls.
