The difference between internal and external painting
Posted on: January 8, 2025, Categories: Exterior House Painting, Exterior Painting,
Painting is one of the most common methods to improve the appearance of your house, however there are many other possibilities as well. We have to consider both the interior and exterior of our house when doing a total renovation, which leads to the issue of painting both of them. We will take a deep look at both interior and exterior paints in this article.
Paint Types:
All paints can be divided into two main groups: oil-based paints and water-based paints, which also include latex or acrylic paints. Because it was more economical and long-lasting, oil-based paint was frequently applied to external surfaces. But due to evidence that it is hazardous to the environment and your health its usage has decreased.
Water-based paint:
Nowadays, water-based paint is often used for exterior and interior painting. Numerous chemicals have been improved to increase adhesion and coverage, and it has several benefits, including a quicker drying time, less odor, and a considerable reduction in the amount of volatile organic compounds (VOCs) released during the drying process.
Oil-Based Paints:
Oil-based paints contains oil, either natural or artificial, as one of its primary ingredients. It is very hard to dry so, it is incredibly resilient to dents and scratches. Additionally, it will resist stains as well.
Oil-based paint is very durable, making it perfect for woodwork that may need to endure heavy activity, such baseboards, bookshelves, doors, window trim, and cabinets. It is a wise choice for kitchens too because the oily foundation also creates a glossier surface which is simple to clean.
Interior and Exterior Paints:
Paints are separated according to their intended use, such as metal, wood, marine, and industrial paints. When it comes to paint for the domestic uses, two categories immediately spring to mind: exterior paint and interior paint.
The formulation makes both of them different. For simple housekeeping, interior paints must be long-lasting and easily wipeable. On the other hand, exterior paints require weather resistance and UV protection in order to last for a long time on the outside of your house.
Properties of Interior Paint:
This kind of paint is applied for aesthetics and decoration. Interior paint also provides qualities like simple maintenance, washability, and moisture resistance.
The formulation of inside paint makes it resistant to scars. It is also intended to be gentler than exterior paint because it shares the same area as humans.
This kind of paint is scrub-able and stain-resistant. It has no fade-resisting qualities because it is not exposed to sunshine. Furthermore, sunshine is not necessary for it to heal.
You can also wash markings and stains from children and dogs, as well as markings from rollers and brushes.
Exterior Paint improves your house exterior while withstanding the weather. It is exposed to harsh temperatures, wind, rain, and UV radiation. Due to its permeable composition, mildew cannot grow since water cannot become trapped. Molecules in flexible resin can expand and shrink in response to temperature changes. Additionally, its flexibility aids in resistance to discolouration, peeling, and chipping.
There should be very few or no volatile organic compounds in interior paint. This lowers health hazards and is essential for maintaining household air quality.
Properties of Exterior Paints:
Among the varieties of exterior paint are acrylic, latex and oil-based. Oil-based paint is less popular than latex and acrylic paint due to its hazardous fumes. Outdoor spaces with adequate ventilation are ideal for oil-based exterior paint. Compared to interior paint, weather-resistant outdoor paint has more volatile organic compounds. Because of its design, it can stick to rougher surfaces including stucco, brick, metal, and wood. Exterior paint offers fewer color and finish options.
When to Apply Each Paint Type:
The success of any painting task depends on knowing when to use exterior paint or interior paint. The guidelines are straightforward: interior paints provide a long-lasting finish that is simple to clean and maintain as they are made for the regulated climate of the interior. On the other hand, exterior paints are the heroes of the outdoors; they are designed to withstand the damaging effects of UV rays and to deal with the unpredictable weather and temperature fluctuations.
Because interior paint lacks the essential protection from the elements, trying to apply it to an outdoor surface may be an expensive mistake that results in a finish that is prone to peeling and splitting under harsh conditions. On the other hand, exterior paint’s composition is not appropriate for your house interior because of its greater volatile organic compound concentration.
