Different Types of Paint for Interior and Exterior Surfaces

0 14

One of the most common mistakes many people make when selecting paints is not knowing the difference between paints suitable for exterior surfaces and that ideal for interior surfaces. While interior paints are specifically made to give rooms bright and smooth looks, exterior paints protect the sun, rain, and other outside elements. They are also made for easy maintenance. To ensure that your project uses the right paint, you can hire professionals such as Surepaint for interior paintRead below to know the different types of paint for interior and exterior surfaces.

Water-based paints

Water-based paints are probably the best option for interior surfaces. They generally provide good coverage and are relatively easy to work with. Since the solvents in water-based paints are not harmful, they don’t leave behind toxic residue when they are dry. They are also easy to clean up with soap and water. The disadvantage of water-based paints is that they tend not to stick to surfaces well, so they are not suitable for exterior surfaces exposed to harsh conditions.

Oil-based paints

Oil-based paints are usually composed of a binder (either an oil or synthetic resin) and pigments, which give it its colour. Oil-based paints have some advantages over water-based ones: they dry slower than their counterparts (thus providing more working time), are less affected by moisture, and allow for better adhesion to surfaces. However, oil-based paints have some disadvantages as well: fumes from the solvent can be harmful if inhaled in large amounts (hence why you should always use a respirator mask), solvents take longer to evaporate, which means that you should avoid using them in closed spaces, and they are more expensive than water-based paints.

Alkyd-based paints

Alkyd-based paints fall between oil-based and water-based paints. They dry faster than their counterparts (though not as quickly as water base) but have a longer working time than oil-based paints do, and they also resist moisture better than most of them. The main drawback of alkyd-based paints is that they are very flammable, so you should avoid using them in areas where there might be excess heat.

Masonry paints

These types of paint have been explicitly designed on brick and masonry surfaces. They usually contain acid-resistant pigments, which allow them to stick better on porous surfaces, and their ingredients are generally more resistant than those in ordinary paints.

Latex-based paints

Latex-based paints provide excellent coverage, and they don’t require much maintenance once dry. Moreover, this kind of paint is often used for interior painting because it renders a smooth finish that is easy to clean up after drying. Latex-based paints can cover a wide variety of different materials, including wood, metal, masonry, and plastic.

Enamel paints

Enamel paints are durable, and they offer a good finish. They provide good protection for exterior surfaces such as wood. However, they are not suitable for interior surfaces because it tends to be tough to clean up after drying.

Polyurethane paints

Polyurethane paints are designed to provide reasonable protection, and they are a good choice for exterior surfaces, but they can be challenging to clean. Moreover, they are best for painting wood but not necessarily suitable for painting floors.

Vinyl paints

Vinyl paints are made from vinyl resins that have pigments, and solvents added to them. They are the least toxic types of paint since they do not contain any nitrates or aromatic compounds. They cost more than latex paints but less than oil-based and alkyd-based ones, thus making them a good choice for people who want to save money on their painting projects without compromising quality.

Epoxy paints

Epoxy paints are usually composed of a binder (epoxy resin) and polymer pigments. They are suitable for many different surfaces, including metals and plastics. Their main advantage is that they are very durable, thus making them an excellent choice for people who want to paint their cars or boats. 

Acrylic paints

Acrylic paints are polymerized acrylic resins, making them water-soluble and transparent. They are not very durable and therefore have limited uses, but on the other hand, they can be easily removed without damaging most surfaces (unlike enamels). Acrylic paints also dry faster than oil-based or alkyd-based ones, making them suitable for people who want to paint smaller areas of their homes.

Choosing the best paint is a vital decision. Like all decisions, it shouldn’t be made in haste. Instead, collect the requisite information first. Hopefully, this article has provided you with the details you need to make an informed decision when painting your property.
