When it comes to painting your house, primer is an element that should never be underestimated. While some may view it as just a step in the painting process, primer plays a role in ensuring a durable and professional-looking paint job. Let’s get into the significance of primer and why it should be a part of any house painting project.

What is Primer?

Primer is a coating applied to surfaces prior to applying the paint. Professional house painters in East Auckland always apply a coat of primer before painting. Its purpose is to create a smooth surface while improving the adhesion of the paint. Depending on the type of paint used, primers can be either oil-based or water-based.

The Advantages of Using Primer

House painters in East Auckland always vouch for utilising primer before painting your house, as it provides many advantages:

1. Adhesion 

One primary function of primer is to enhance the adhesion between the paint and the surface. It fills in any imperfections or rough areas, allowing for adhesion of the paint. This proves beneficial when dealing with surfaces prone to peeling or chipping.

2. Increased Longevity

Primer serves as a layer that safeguards against paint absorption on surfaces, resulting in a more resilient finish. This is especially crucial for materials like wood, drywall and concrete that tend to absorb paint. 

3. Enhanced Paint Coverage 

Primer plays a role in establishing a foundation for the paint, allowing for improved coverage and eliminating the need for multiple coats. By sealing the surface and preventing paint absorption, primer ensures that the colour appears vibrant and consistent.

4. Time and Cost Efficiency

Although it may seem like an extra step, utilising primer can actually save you time and money in the long term. By providing coverage and adhesion, primer reduces the number of coats needed to achieve desired results. This translates to less paint usage and less time spent applying layers.

5. Stain Blocking 

Certain surfaces, such as wood or walls with water stains, may require preparation to prevent stains from seeping through the paint. Primer, with stain-blocking properties, effectively blocks these stains, ensuring a clean appearance.

When Should You Use Primer

Primer is highly recommended in the following situations:

1. New Surfaces 

When painting a surface that has never been painted before, it’s important to use primer. This is especially crucial for materials like wood, plaster or drywall, as they can absorb paint differently and lead to an uneven finish. Applying primer creates a consistent surface for the paint to adhere to.

2. Resurfacing 

Even when repainting or resurfacing a painted surface, it may still be necessary to use a primer. Primer helps with adhesion and prevents paint from bleeding through, particularly if you’re transitioning from dark to light colours or vice versa.

3. Repairs 

If you’ve repaired a damaged area, applying primer before painting is essential. Primer seals the section and ensures it blends seamlessly with the surrounding surface.

How to Apply Primer

To ensure a flawless application of primer, follow these steps:

1. Preparation 

Before applying primer, make sure the surface is clean, dry and free from dust, grease or loose particles. Clean with soap and water. Lightly sand the surface to create a rough texture that enhances adhesion.

2. Primer Selection 

Choose the right type of primer for your project. For instance, if you’re dealing with a surface near high-traffic areas, it is recommended to go for a primer that blocks stains. Additionally, take into account the type of paint you’ll be using and choose a primer that’s compatible with it.

3. Application 

Apply the primer using a quality brush or roller, making sure to achieve a thin layer. Follow the instructions provided by the manufacturer regarding drying time and additional coats.


Primer plays a role in any home painting project. Its advantages are numerous, including enhanced adhesion and durability, better coverage and time-saving benefits.

By utilising primer, you can achieve a long-lasting paint job that will elevate the aesthetic appeal and value of your home. It is time you undertake a house painting task; remember the significance of using a primer!
