//6 Reasons to Use a Wall Primer Before Paint

You may or may have not heard of a wall primer before. Many of us who are familiar with a wall primer, often have different opinions when it comes to using it.

Experienced painters that take pride in their work will always prime your walls first. Many who choose to paint their own walls often skip this step, but priming is always the best way to paint a wall.

There are times that you can get away with not priming your walls, but there are also times that you have to prime your walls. Therefore, it is important to understand the importance of a wall primer and know when to use it.

1. Drastic Colour Changes Need a Wall Primer

Dramatic colour changes are our number one reason for using a wall primer. The truth is if you know a thing or two about colour theory, then you have the basic knowledge of how colour works.

It is nearly impossible to go from a dark colour to a lighter colour without a wall primer. This is not to say that you can not achieve this, but it will cost you both time and money. You will need multiple paint coats to cover your original dark colour. The number of coats also depends on how light your new colour is.

If you have the time to paint a coat, let it dry, and do it all over again then you can skip this step. However, if you are looking to achieve a better result, it is always recommended to use a wall primer. You will save on your costs too because a wall primer is cheaper to use than paint.

2. Wall Primer For New Drywall and Bare Wood

A wall primer is needed for both new drywall and unpainted wood. If you try and apply a coat of paint on any of these two surfaces without a primer, you will see that the paint quickly disappears.

This is because both new drywall and bare wood are highly porous. As a result, your paint is quickly absorbed into the surface. If you want a consistent appearance, then always use a wall primer on new drywall and bare wood.

3. Stained Walls

After a while, stains and damages will always appear on your walls. They often happen to bleed through your new paint, but this also depends on the paint colour that you are using.

By priming your walls first, you can ensure to eliminate any stains that could bleed through your new paint. There are many stain-blocking primers that you can choose from, but we recommend you to use the highest-quality primer for those greasy spots and crayon marks that you may have.

4. Eliminate Odors

Believe it or not, your walls soak in odours over time, and there is specific odour sealing primers that you can use for this. Homeowners with pets or smokers know exactly what we mean by that.

If you want your home to smell fresh then you need to use a primer first. Paint alone cannot remove the odours, but a primer will ensure to seal your walls properly to keep those odours away.

5. Glossy or Oil-based Paint

Before you begin to apply your new paint, you must consider the existing type of your current paint. Both glossy and oil-based paints cannot hold your new paint well.

The new paint that you are going to apply needs a surface it can adhere to. As a result, you always need a wall primer on glossy and oil-based paints. There are specific primers that you can use that are only for glossy and oil-based painted walls.

6. High Humidity

Ground floor and basement flats will always suffer from high moisture. High moisture turns into condensation on your walls and increases dampness.

Mould spores thrive on damp surfaces, and therefore can easily grow on your walls. You can prevent the growth of mould on your walls by using a mould-resistant wall primer.
