A Beginner’s Guide to the Different Kinds of Interior and Exterior Paints

Different paints have their own different properties. These properties are what make them suited for different parts of a building.

While paints for building or home interiors are made to resist staining or are made to be scrubbed for easy cleaning, exterior paints are made specifically to resist harsher environmental factors, such as fading and mildew.

What’s in the Paint?

In order to fully understand the difference between interior and exterior paints, you have to know beforehand that paint is essentially composed of the following things:

  • Binder (typically resin, which holds the pigment to the surface),
  • Solvent (which reduces the paint’s viscosity for better application),
  • Pigment (which gives the paint its color and opacity),
  • Extender (which improves adhesion in the paint), and
  • Additives (which modify the paint’s properties).

Solvents and pigments in both interior and exterior paints are similar in a lot of ways. For instance, you can use either water- or oil-based paint for outdoor paint jobs, as the binders and additives in the paint make it so that they resist external factors such as prolonged exposure to heat and rain.

However, they also have their differences. For instance, oil-based paint is almost used exclusively as an exterior paint because of the difficulty in cleaning up, as well as the strong odors and potential fumes, and most interior paints are water-based because of this.

Interior Paints

Interior paints are made to be cleaned easily and resist staining, which means that the binding resins are rigid to keep the paint from getting scuffed or smeared. This usually means that interior paints are water-based, which in turn makes them safer for indoor use.

Interior, water-based paints also have a few other advantages, such as having a faster drying time and are easy to clean up using water.

Exterior Paints

Exterior paints are made to resist mildew and fading, as prolonged exposure to heat and rain are more likely to fade interior paints. Aside from the attractive gloss of oil-based exterior paints, they also have a smooth, durable finish.

The secret lies in their binders (aka resin), which are softer to allow the paint to better resist not just the previously mentioned environmental factors, but also peeling and chipping.

Which One to Use?

At the end of the day, the primary difference between the two is the solvent. There are certain paints that can be used for both indoors and outdoors, but they do have their own tradeoffs despite their versatility.

To know which paint is best suited for the job, be it oil- or water-based, always be sure to consult a professional painter or talk to a professional painting firm where a representative can walk you through everything that you need.

The Different Kinds of House Painting Equipment

When painting your house, always be sure to have the right tools you need to complete the job. While you may already own some of these items, there may be others that you still don’t, and should consider investing in:  

1. Paint rollers, brushes, paint sprayers

While all three are used for applying paint on surfaces, they are meant to be used in different ways. For instance, paint rollers are for painting smooth surfaces in broad swaths.  

There are different types of brushes used in painting: bristle brushes, which clear up loose material from walls and floors, and wire brushes, which are great for removing plants, moss, and flaking paint. 

There even mildew brushes, which remove mildew and dirt, as well as long-handled brushes for clearing out large, exterior surfaces.

Meanwhile, paint sprayers are used quick, even applications of paint that can be used in the place of paint rollers and brushes. The key to using a paint sprayer is having the right kind for the job you need done.

2. Paints, finishes, and primers

Primers are the first coat of paint and are the initial whitewash that will bind the other coats of paint to the surface you’re painting it on. Meanwhile, finishes are there to add the desired glossiness.

3. Roller tray, grid, paint pail

Roller trays and grids are used for loading paint into rollers, and the paint pail is a container for carrying paint to the site with ease.

4. Stepladder, extension ladder

For ceilings that can be a little hard to reach, having a stepladder will save you a lot of time and will even allow you to access areas that you wouldn’t have. It also keeps you from having to balance yourself on tables and chairs, which is highly unsafe.

5. Tape measure, painter’s tape, masking tape

Tape measure allows you to accurately measure surfaces (i.e. walls, floors, and ceiling) for marking off, which will in turn save you on how much paint you will need to use.

Painter’s tape and masking tape are a must-have when it comes to protecting trims or sections of surfaces that you don’t want to get paint on.

6. Spackling paste, caulk and caulking gun

Spackling paste and caulk are used to even out imperfections and crevices in wall surfaces, but they have their own different uses.

For instance, spackling paste is used mostly for filling nail holes and smaller imperfections in walls, while caulk is mostly reserved for evening out gaps and seams in woodwork. If you do happen to be working with wood, always be sure to use ones that can be painted on.
