Why Contractors Always Use Primer Before Exterior Painting?

When painting the outside of your home, it’s important to use a primer. But you might wonder why an extra step is necessary for the anticipated colourful aftermath. Here is why primer is so important before you start painting your home.

What is Primer, and Why is it Necessary?

Primer is an initial coating applied to surfaces before painting. It serves several important purposes that contribute to the longevity and quality of your exterior paint job:

1. Surface Preparation:

A primer is essential for creating a seamless, consistent surface that allows the paint to stick well. It fills in small imperfections and promotes better glueing, ensuring that the topcoat of paint goes on evenly and lasts longer.

2. Enhanced Durability:

Primer helps prevent paint from peeling or cracking by creating a strong bond with the surface. This added durability is especially crucial for exterior surfaces exposed to harsh weather conditions.

3. Stain Blocking and colour Enhancement:

Some primers contain ingredients that block stains and hide underlying colours, providing a clean and uniform base for the final paint colour. This is particularly important when covering dark or discoloured surfaces with lighter hues.

The Process of Exterior Painting: Why Primer Comes First

Imagine your home as a blank canvas awaiting the perfect brush strokes of colour. Here’s why contractors always start with primer before applying the best colour combinations for exterior painting:

1. Preventing Moisture Damage:

Primer is essential for protecting your home from moisture, mold, and mildew by forming a barrier that prevents water damage. You can find out more about home painting services online.

2. Enhancing Colour Accuracy:

Applying primer before painting allows the true colour of the topcoat to shine through, achieving the desired hue with greater clarity and vibrancy. This is especially important when transitioning between light and dark colours or covering surfaces with different underlying shades.
