Home Exterior Painting Tips: What You Need to Know Before You Start

Are you ready to spruce up your home’s exterior with a coat of paint? If so, you’re in for an exciting DIY project — with a few hits and some misses. As with any home renovation project, there’s a lot to consider before you start painting: materials, weather, safety, and more.

So to give your curb appeal a makeover to remember, here are some essential home exterior painting tips that you need to know before you swing your first brush. Get ready to give your home a layer of love to last you years to come!

Weather Conditions and Temperature

When it comes to painting outdoors, weather conditions should always be taken into consideration before any work begins. Being mindful of the temperature and precipitation levels can be a decisive factor in the quality of the paint job.

Humidity and Temperature Considerations

When it comes to humidity and temperature, careful consideration should be taken when painting the exterior of your home. Humidity is generally higher in the morning, which can cause condensation to form on surfaces. This can create problems with adhesion, so it’s best advised to wait until midday or later before you apply your primer or paint. Temperature plays in important role in paint application as well. Generally, temperatures lower than 50 degrees are not ideal for exterior painting. A good rule of thumb is that if you experience cold at night in your area, you won’t want to paint outdoors during the day. You’ll want to wait until temperatures reach at least 55 degrees before beginning a project.

It can speed up the drying of the primer and topcoat, resulting in an uneven finish because of differences in sheen that may have occurred due to application technique variations. It’s best advised to stay away from extreme hot weather conditions and aim for ideal temperatures around 70-85 degrees Fahrenheit.

Now that we’ve explored both possible weather extremes, let’s discuss ways to protect your home exterior against them causing harm during painting projects!

  • According to a survey, painting the outside of your home has been shown to increase its property value by an average of 5-10%.
  • A good quality exterior paint job typically lasts 7-12 years.
  • Studies have found that certain colors can help reduce the temperature on external walls by up to 14 degrees Fahrenheit.

Protecting Against Extreme Weather Conditions

Once humidity and temperature considerations have been taken into account, another important factor to consider for exterior painting is protection against extreme weather conditions. Painting outdoors comes with a level of exposure to severe weather that must be prepared for. As temperatures fluctuate, it’s vital to take time to inspect the painting before and after each climate change.

Excessive heat can cause paint to bubble up due to moisture being trapped beneath the surface. Extreme cold temperatures can render some paints and coatings completely unusable as they may freeze while in application and cracking will occur when thawed. Homeowners should also plan in accordance with inclement weather like storms, windy days, or high humidity levels.

As such, it is important to protect the job site and materials from any harsh weather conditions. Plastic sheeting can be used to cover any exposed surfaces and window films can help prevent any dust particles from settling onto wet paint surfaces.

Applying these coverings are relatively easy decision compared to choosing how often you should monitor the humidity and temperature levels steadily or if you need drastic action, such as turning off the air conditioner temporarily or using a dehumidifier to reduce indoor moisture levels due to higher outdoor rain conditions.

By understanding all factors when planning your painting project, you can properly prepare your home’s exterior by protecting it against extreme weather conditions. Once accomplished, you’ve gone a long way towards ensuring that your project outcomes arrive in good condition and last for many years of future enjoyment under the element’s onslaught.

Exterior Materials and Surface Protection

Once the exterior of your home has been adequately protected from extreme weather conditions, you can begin to think about the surfaces that will be painted and what materials may need to be used. Typically, an exterior wall is either masonry, a composite, or wood siding.

Masonry requires a special primer and sealant in order to make sure that the new paint sticks properly. Composite siding requires a similar preparation process where a special sealant needs to be applied before it can be painted. Wood siding is often easiest when it comes to painting as all that is needed for adequate protection is to sand and smooth the surface before applying paint.

It’s also important to consider the type of paint being used on the exterior of your home. It’s often best to use an exterior-grade acrylic-latex paint as this type of exterior paint offers excellent protection against mildew, moisture damage, fading and chalking.

Oil-based paints offer a more durable finish but require more layers of protective coating and are prone to yellowing over time. Ultimately, when selecting which type of paint you should use for your project, consider the climate in which your home exists and what features will give you the best amount of protection for your investment.

Finally, once the surface has been adequately prepared, it’s a good idea to give it an extra layer of protection with a sealer. Sealers are typically available in clear or semi-transparent colors and provide an extra layer of insulation against wear and tear from rain, snow, sun exposure and everyday dust accumulation. A clear coat of sealer also gives surfaces a beautiful shine that makes them look brand new for years to come.

Now that you have a better understanding of exterior materials and surface protection, it’s time to move on to prepping your home so you have the best possible finished product–prep work is key in achieving a quality paint finish!

Prep Work to Ensure Quality Paint Finish

Now that you’ve considered the exterior materials and have taken steps to protect any vulnerable surfaces, it is time to begin the prep work for the painting process. Every surface must be thoroughly cleaned and prepped in order to ensure a quality paint finish. This involves pressure-washing, scraping, and sanding any loose or flaking paint.

Controversy does exist over whether to use sandpaper or steel wool when it comes to preparing a surface for painting; proponents of sandpaper argue that it can leave a smoother finish than steel wool which may help improve the look of your overall project.

However, many disagree; some argue that steel wool leaves behind fewer fibers that can interfere with paint adhesion while also providing more flexibility while you work on uneven surfaces. For the best results do your research and consider what the experts recommend for your specific situation.

No matter which method you choose, taking the time to properly prepare your home’s exterior can make an incredible difference in the longevity of your paint finish. It certainly requires an investment of time and energy but this critical step will more than pay off when you come away with a sleek-looking finish that is sure to last through all changing weather conditions.

With the prep work complete, you are ready to move on to the next step: safety precautions during the painting process. Taking safety into account is always important whenever dealing with any project involving power tools or chemicals, especially those performed outdoors where circumstances can change quickly and unexpectedly. Optimizing your safety measures now will not only result in a successful project but also peace of mind.

Safety Precautions During the Painting Process

Safety is paramount when it comes to exterior painting. Before beginning, it is important to read through safety precautions relevant to the particular materials being used and follow guidelines accordingly. Oftentimes, homeowners must wear protective gear such as gloves, goggles, and a respirator to protect against splashes of paint or fumes from solvents that may cause irritation. Additionally, steps must be taken to avoid accidents like falling off ladders or scaffolding while reaching higher up surfaces.

While there may be debate surrounding the need for professional help when it comes to exterior painting, taking all necessary safety measures is of utmost importance regardless of who is doing the work. For example, one should always check the conditions of their ladders prior to use and do a walkthrough of the area where the painting is about to take place for any nails, sharp protrusions or other hazards.

An experienced painter should also understand which materials are most appropriate for particular areas and circumstances — such as using outdoor paints on outdoor surfaces — in order to ensure a high-quality job without compromising safety.

Professional painters often have access to special paints not available for homeowners that may be more durable in harsher climates as well and would thus be better suited for certain projects. Ultimately, researching and seeking out professional help when necessary could save time and money while also protecting you from potential harm. Taking extra precautionary steps such as these can lead to a safe and successful exterior painting project.


Painting a home’s exterior can be a daunting task, but with the right preparation and safety measures in place, you can create a beautiful finish that will last for years to come. Taking the time to prepare the surface properly is of utmost importance. Once the prep work is done, be sure to double-check safety precautions and take all necessary steps to ensure your protection. As long as you are diligent in these areas, you can enjoy a successful and beautiful exterior paint job that will last for years.
