Common Mistakes to Avoid When Painting Your Home’s Exterior

Jun 10, 2024Home Value

Giving your home’s outside a fresh coat of paint can make it look bright and new again. But painting the exterior is tricky. If you’re not careful, you could end up with a streaky, flaky mess! 

Let’s go over common mistakes homeowners often make when tackling this project.

Painting Pitfalls When Refreshing Your Home’s Exterior

Here are some of the most common mistakes to avoid when refreshing your home’s exterior:

Not Preparing the Surface Properly

The most important step happens before you even pick up a paintbrush. You’ve got to prepare the surface by:

  • Scraping off any loose, cracked, or peeling old paint
  • Sanding rough areas until they’re smooth
  • Wash everything down to remove dirt, mildew, and chalk

If you skip this preparation work, the new paint won’t be able to grip and will start flaking off in no time.

Picking the Wrong Paint

Using the right type of paint is important for an exterior job. If you plan to use the paint outdoors, choose a high-quality acrylic latex paint with 100% acrylic content. Compared to cheaper interior paints, these hold up much better against the sun, wind, and rain. When in doubt, ask for help at the paint or hardware store to ensure you use the most durable option for your climate.

Not Allowing Proper Dry Time

Exterior paint takes longer to dry and cure fully than interior paint. Be patient! If it’s hot or humid outside, the paint could take over a week to harden completely. If you try to rush it by adding an extra coat too soon, the layers won’t be able to bond properly. This makes it very likely that the paint will start cracking, peeling, or bubbling soon after.

Skipping Primer on Tough Surfaces

While primer isn’t always necessary for every exterior project, there are some cases where it’s an absolute must:

  • Painting over stains or bleed-through areas
  • Switching between oil-based and latex paints
  • Painting over slick, non-porous surfaces like metal or plastic

Without primer, the new topcoat won’t stick to these tricky spots. Over time, the paint will lose its grip and peel right off.

Painting in Bad Weather

Painting the outside of your house is an outdoor activity, so you’ve got to keep an eye on the weather forecast. Avoid rainy or super humid days, as moisture can prevent full curing. Extra hot and sunny conditions aren’t ideal either. The best temperature range is between 50 and 90 degrees Fahrenheit, with minimal wind and mild humidity. These moderate conditions allow the paint to dry evenly and grip well.

Not Using Proper Safety Gear

Don’t forget to protect yourself from accidents when scaling ladders and handling toxic materials like paint and caulk. Have the proper safety equipment on hand:

  • Safety goggles
  • Chemical-resistant gloves
  • Properly stabilized ladders or scaffolding
  • Hard hat (if working at serious heights)

Splattering paint into your eyes or taking a nasty fall can quickly ruin your paint job and pose serious risks. Play it safe by dressing up appropriately.
