Choosing exterior and interior house paint – should you consult a professional?

Do you need to consult a professional when choosing exterior or interior paint for your house?

It’s not as easy as just going to the local hardware store to pick up a bucket of paint and splash it onto your walls. There are many factors that go into choosing the right paints for your home’s exterior and interior paint colours.

We’ll discuss what goes into your paint, and the differences between exterior and interior paint. You will always know what paint you should use.

These are the main components of any paint

You need to understand the components of all paints in order to appreciate why they are different. The four major components of any paint are pigments and solvents. resins and additives. These four components are what give paints their unique properties and which surfaces they can be used on.


Pigments are finely ground particles that are added to the paint to give it colour.


Solvents are liquids that have all other components suspended in them. These solvents give the paint its water content and make it easy to spread across surfaces. Latex paints are primarily water-based. The solvent in latex paints, whether oil-based paints or alkyd-based paints, will typically be either water or a mixture of solvents. The solvent evaporates as the paint dries and leaves behind other components.


These additives give the paint its properties. The colour accuracy of paint is affected by additives. They aid in the prevention of mildew development, determine ease of application and influence how easy it is to clean after the paint has dried.


Resins, also known as binding are what hold your paint to the surface. These resins hold pigments together to form paint film. They can be made from silicone, acrylic, seed oil derivatives, and epoxy.

Soft resins

  • Make the colour last longer endure temperature changes,
  • Moisture resistant,
  • Better Adhesion
  • Prevent paint from UV fading due to sunlight

There are many differences between exterior and interior paint

Both exterior and interior paints have different additives that help to regulate drying times and maintainability over time. Because they don’t contain heavy-duty additives, interior paints will not last long outside.

Many exterior paints can’t be used indoors as the additives can make them unhealthy and dangerous when used in enclosed spaces where fumes don’t disperse fast enough.

You can use some paints indoors or outdoors. Because of their greater versatility and utility, these paints are usually more expensive.
