The Importance of Priming Before Exterior Painting

Introduction

Homeowners who want a quick, economical, but effective way to refresh and update the look of their properties turn to painting.  Not only does a fresh coat of paint beautify your home, but it can also protect it against the elements and help extend its life. The not-so-secret of an exterior paint job’s success doesn’t only lie in quality paints and well-chosen tools. Prep work is also crucial to achieve the desired results in your paint job.

In addition to cleaning the exterior surface, priming is essential depending on the surface type and condition, the paint you choose, or a drastic color change. Priming can be a necessary part of surface prep work that helps the finishing paint adhere better to the surface, resulting in a durable and long-lasting paint job.

To prime or not to prime?

Whether or not to prime the exterior surface of your home before painting depends on several factors:

Surface condition: If the surface is in good condition, clean, and smooth, you can skip priming. But if it’s rough, porous, or has stains, priming is recommended to create a smooth base for the paint.

Type of surface: Certain surfaces like bare wood, metal, or masonry may require priming to ensure proper adhesion and longevity of the paint job.

Type of paint: Some paints have built-in primers or are formulated to adhere well without a separate primer. Check the manufacturer’s instructions to see if priming is necessary for your specific paint.

Weather exposure: If the surface is exposed to harsh weather conditions, priming can provide an extra layer of protection against moisture and UV rays, extending the paint job’s life.

Color change: If you’re drastically changing the color of the surface, especially if going from dark to light or vice versa, priming can help achieve better coverage and color accuracy.

In general, it’s often recommended to prime exterior surfaces before painting, especially if there are any doubts about the surface’s condition or the paint’s compatibility. It’s an extra step that can significantly improve the durability and finish of the paint job in the long run.

You want to update your home’s exterior with new paint and color schemes to enhance its curb appeal. But you know that exterior painting can be complex and risky, so hire a professional contractor. By leaving the job to the pros, you will save time, energy, and stress. But is there any responsibility left for you in the project?

Yes, you still have a role in the project! While you may not have the skills or training to paint your home, you still can contribute by preparing your home for professional painting. It is a big job, so before signing a contract, discuss with the contractor whether they will allow you to prepare the site before the crew arrives on painting day. 

Many contractors may include prep work elements in their job estimates or be willing to do it for an extra fee. However, they may allow you to do the worksite preparation and thus exclude it from their job estimates. 

One of the main benefits of preparing the site by yourself is cost savings. You may have to sweep your deck or trim the bushes, but a little effort won’t hurt. Besides, you’ll be able to save money while still getting the benefits of a professional paint service. 

Before your contractor comes to paint your home, several responsibilities fall on you to ensure the site is properly prepared:

  • Clearing the area – Remove any obstacles or items from the work area, such as outdoor furniture, potted plants, decorations, etc. This ensures easy access for the painters and prevents accidental damage to these items.
    • Trimming vegetation – Trim back any bushes, shrubs, or trees obstructing the painting surface. This includes cutting back branches that may be touching or close to the walls.
    • Turning off the sprinklers – If your sprinkler system has a set timer, turn it off before the crew arrives on painting day. You don’t want them to get soaking wet. Also, you don’t want some water drips or streaks landing in the paint finish.
    • Protecting surroundings – Cover nearby plants, windows, doors, and other surfaces that will not be painted to protect them from overspray or accidental paint splatters.
  • Keeping children and pets away (and cleaning after them) – Arrange to keep children and pets away from the work area. It ensures their safety and prevents any accidental disturbances to the painting process. If your pets or children leave some mess in the work area, clean up their waste and dispose of it properly.
  • Checking weather conditions – Ensure that weather conditions are suitable for painting. Avoid painting in extreme heat, cold, rain, or high winds, as these conditions can affect paint application and drying times.
  • Communicating with the painter – Discuss any specific concerns or requirements with the professional painter before they begin work. This includes discussing color choices, paint types, scheduling, and other relevant details.

By taking care of these responsibilities, homeowners can help ensure that the painting process goes smoothly and that the finished result meets their expectations.

Making repairs

Guide to fixing common exterior surface problems

Fixing common exterior surface problems is crucial before painting to ensure a smooth, durable finish. Here’s a guide to address some of the most common issues:

Peeling paint

  • Cause: Usually due to moisture getting underneath the paint, poor adhesion, or painting over a dirty surface
  • Fix: Scrape off the peeling paint, sand the area to smooth out the edges between the peeled and non-peeled areas, prime the bare surface, and then repaint.

Mildew

  • Cause: Forms in areas with moisture, poor ventilation, or shade.
  • Fix: Clean the surface with bleach and water (1 part bleach to 3 parts water) or a commercial mildew cleaner. Wear protective gear, scrub the area, rinse thoroughly, let it dry, and then apply paint.

Cracks and gaps

  • Cause: Movement in the building, settling, or temperature changes.
  • Fix: Use a high-quality exterior caulk to fill small cracks or gaps around windows, doors, and trim. For larger cracks, you may need to use a patching compound. Allow it to dry according to the manufacturer’s instructions before sanding smoothly.

Chalking

  • Cause: Degradation of the paint due to sunlight exposure, leading to a powdery residue.
  • Fix: Clean the surface with a power washer or hand-washing with a detergent solution. Rinse thoroughly and allow it to dry before repainting.

Efflorescence

  • Cause: Salt deposits that come to the surface of masonry or concrete as moisture moves through the wall.
  • Fix: Remove by scrubbing with a stiff brush, water, and muriatic acid (following the manufacturer’s safety instructions). Neutralize the acid with water, rinse the area well, and let it dry before painting.

Rust stains

  • Cause: Metal fasteners or fixtures corroding over time.
  • Fix: Remove rust with a wire brush, sand the metal until smooth, prime with a rust-inhibiting primer, and repaint.

Wood rot

  • Cause: Typically occurs in wood that is frequently exposed to moisture.
  • Fix: Remove the rotted wood, treat the healthy wood with a wood hardener if necessary, and then fill the area with a wood filler. Sand smooth once dry and apply primer and paint.

Fading paint

  • Cause: Exposure to sunlight and elements, using a paint color that’s not resistant to UV rays.
  • Fix: There’s no fix for fading other than repainting. Use high-quality, UV-resistant exterior paint; consider lighter shades that fade less noticeably.
