What Does Paint Primer Do?
In a world where no door handle goes untouched and no seat goes un-sat on, it’s no wonder why small scratches and marks appear on everything we use. But is this due to general wear and tear or a bad paint job?
Primer exists to reduce these small imperfections and stop bigger issues occuring, like corrosion and mildew. But what else does primer have to offer?
In this article, we will cover:

What Is Paint Primer?
Primer adds another step to your DIY project, unless your paint already includes primer, like ours. However, if you need to buy paint primer separately, you need to know what type you need, including colour, benefits, and thickness. But what is paint primer and why is it important?
Paint primer is an undercoat substance applied to surfaces before painting. It allows the main paint to efficiently stick to the surface and resist damage over time. It can also hide surface stains and lighten dark colours so you can use a brighter one for your main paint.
What Does Paint Primer Do?
Paint primer has many benefits you likely haven’t considered before. It’s common knowledge that primer can make your paint long-lasting, but what does paint primer do specifically?
- Hides stains and odours
- Tones down dark colours
- Better adhesive for your paint
- Seals pores in unpainted surfaces
- Covers patches and repairs
- Reduces the strength of topcoat needed
- Resistance against certain chemicals
- Reduces corrosion and mildew
- Protects against marks and scratches
- Prevents chipping and scuffs
- Can provide anti-slip properties
- Better weather and UV protection
Not every paint primer will offer these benefits. In fact, most primers are created with just a set of advantages in mind. If primer is already included in your paint but doesn’t provide all the features needed, there is nothing wrong with purchasing another primer type for better protection.
What Is Primer Paint Used for?
The type of primer you buy will determine what surface it can be used on. Typically, paint primer in general can be used on any surface or material because it’s so important.
Knowing that, what is primer paint used for? Well, it’s commonly used for:
- Metal benches
- Wooden tables
- Plastic containers
- Industrial concrete
Do I Need Primer?
Yes, we absolutely recommend using primer!
But just because we recommend it, does that mean you need it? Technically, you don’t need primer, but you won’t see the full benefits. It won’t be as durable or even long-lasting. Ultimately, using paint primer can save you time and money for the same project years later.
When to Use Primer
So, when ‘do I need primer’ for specific projects? If you are simply doing a quick touch-up or painting a small object for fun, you don’t need to buy primer. However, if it’s a big project that requires a lot of time, effort, and costs, and is likely to incur damage, primer is always best.
Here are our tips for when to use primer:
- Porous surfaces
- Walls and floors
- Any surface that gets a lot of use
- Radiators to prevent corrosion
- Unpainted surfaces, such as drywall
- Dark to light colours
- Glossy or oil-based paints and finishes
- Patched or repaired surfaces
- Surfaces will multiple marks or scratches
