What’s the Difference Between Interior and Exterior Painting Services on the Gold Coast?by Marta Jordan Writer
The benefits of a fresh coat of paint are well understood. Clean, well-maintained painted surfaces not only look good but provide valuable protection against external elements. The structural integrity of a property can be greatly enhanced through protective paint coatings applied on a regular, scheduled basis.
However, the difference between interior and exterior paint is not always well understood. The two serve very different purposes and so are considered by professional commercial painters to be separate products and processes.
Teams who provide painting services on the Gold Coast are experts in this distinction, as well as being skilled tradespeople. The value of a property can be significantly increased through regular upkeep of painted surfaces, however it is important that the right product is used in the right environment.
Paint makeup: interior vs. exterior
All paints contain the same basic ingredients, which include:
● Pigments: to provide colour.
● Solvents: either oil or water, create the liquid texture.
● Additives: a range of substances that assist with colour accuracy, improve ease of application and adhesion, and prevent mould growth.
● Resins: bind pigments together.
The main difference between the ingredients of interior and exterior paints is the combination of additives and resins. Additives are typically added to exterior paint to improve weather resistance and so may be missing from interior paints, whilst the resins used in an interior environment allows the paint to be easily cleaned.
Exterior paint provides valuable protection against environmental factors including sun, wind and rain. This means it needs to be tough to prevent peeling and chipping and also mould-resistance, due to the amount of moisture the surface will come into contact with.
The types of additives and resins used in exterior paint are not suitable for an interior environment, due to the chemical strength. Interior paints are typically of a lower ‘volatile organic compound’ (VOC) rating, to protect the health of inhabitants.
Interior surfaces also undergo different stressors, including fingerprint markings, food stains, and dust and cobwebs. Paint used in an interior environment must therefore be cleanable and scrub resistant.
Are they interchangeable?
The short answer — no. It is not advised to use an interior paint on an exterior surface and vice versa.
Using an exterior paint in an interior environment poses great risk to the inhabitants of a building, due to the typically high VOC content found in these products.
An interior paint in an exterior environment will not provide an adequate level of protection against environmental elements. You will find that a fresh coat of paint quickly fades and exposes the structure to potential long-term damage.
There are some paints that are made to suit both environments, however it is recommended that you contact a professional before making any decisions or undertaking painting activities. Teams who provide painting services on the Gold Coast have an in-depth understanding of the environmental considerations and will be able to advise you on a paint selection that is both practical and aesthetically pleasing.
