How to choose paint

How to Choose Paint

Early on in any project, you will need to work out the criteria you need to fulfil and the specifications you are working to in order to choose the best, most appropriate paint.

01 What surface of substrate are you painting?

• What are its qualities and do you need specialist paint to suit these?
• Wooden panelling will require a different coating to a metal radiator.

02 How does this surface act?

• Does it expand? Is it susceptible to moisture?
• More often than not, you will be painting a plaster wall. This requires a breathable paint, and I recommend looking for paint containing natural binders such as lime or clay.
• Look into the SD value to determine the breathability of the paint.

03 What are your own criteria?

• Is there anything you are unwilling to compromise?
• What is your budget? How does this impact the paint you can buy?

04 Do you need to prepare the substrate, and how?

• Is a primer required, and if so, which one?
• Every paint will have its own preparatory system, so follow the manufacturer's recommendations.

05 What sustainability credentials does the paint have?

• Investigate how the paint is made. Even if a paint says it is eco-friendly, you may have to dig deeper.
• Are the ingredients free from fossil fuel derivatives?

06 How durable do you need the paint to be?

• Paint containing binder will fare pretty well against scuffs and splashes.
• Eggshell finishes typically contain more binder.
• Matt emulsion paints that claim to be wipeable will likely contain microplastics which are problematic for the environment.

The main things I look for in a paint

1. Below are the three crucial criteria I apply when choosing paint
2. Its ability to support and maintain the building it's applied to
3. It shouldn't unnecessarily represent an environmental burden
4. The occupants of the building should not be adversely affected
