Paint that cracks or won’t stick is usually a preparation problem, not a paint problem, but what is the difference between paint and primer? To put is simply, primer prepares the surface and paint delivers the colour and finish.
Here’s how each one works and when skipping primer costs you.
What Does Primer Do That Paint Doesn’t?
Primer seals the surface and helps the topcoat bond. On metal, the right primer also adds anti-corrosive protection. It creates a smooth base, but it isn’t designed to look good.
Paint does the visual work; it gives you your colour and a gloss or matt finish. You need both for a lasting result.

Which Surfaces Always Need Primer?
Some surfaces should never be painted bare. These are the surfaces that always need primer:
Concrete: Primer seals the surface and gives paint something to grip. See our concrete paint.
Metal: Primer improves adhesion and protects against corrosion. See our metal paint and steel frame building paints.
Wood: It’s porous, so primer seals it before the topcoat goes on. See our wood spray paint.
What Happens If You Skip Primer?
When you skip primer, porous surfaces absorb paint unevenly. Without a sealed base, the coating can crack and peel early.
Skipping primer also means a rougher finish. You may need extra coats to compensate, and a failed coating means repainting. Primer takes longer to apply. It saves time and money in the long run.
When Should You Use Primer on Floors?
Use a floor primer on any high-traffic floor. Primer gives the topcoat a stable base, so paint applies more easily and needs fewer coats.
It matters most in demanding settings, such as:
Which Topcoat Should You Use Over Floor Primer?
Follow your primer with a quality floor paint. Two pack epoxy floor paint is a durable option for heavy-traffic floors. It can also freshen up older floors that look tired.
Kitchens face constant foot traffic and splashes. Pair your primer with industrial kitchen floor paint for better protection. Where slips are a risk, consider anti-slip floor paint.
How Do You Apply Primer Correctly?
Surface preparation decides how well your coating performs. Follow these steps to apply your primer correctly:
- Clean the surface: Remove dirt and loose material first. Make sure it’s dry.
- Check the data sheet: Technical data sheets cover application methods and drying times for each product.
- Let it dry fully: Apply your topcoat only once you’re sure the primer is ready.
- Use the right tools: Choose suitable brushes or paint rollers.
Our paint thinners are formulated to work with our coatings, so we recommend using them together. Not sure which product suits your surface? Ask our team before you start.
