The Essential Steps to Prepare Your Home for Exterior Paint


Properly preparing your home for exterior paint is crucial to achieving a stunning and long-lasting result. In this comprehensive guide, we will outline the essential steps involved in preparing your home’s exterior for a successful paint job. From planning and pet control to surface preparation and weather considerations, following these steps will ensure a professional and reliable outcome. At Al’s Painting, we pride ourselves on our expertise and commitment to delivering exceptional exterior painting services. Let’s explore the necessary preparations for transforming your home’s exterior.

The Importance of Prep Work for a Paint Job

One cannot overstate the significance of thorough preparation for a successful paint job. Adequate prep work ensures proper paint adhesion, enhances durability, and offers optimal protection for your home’s exterior surfaces. Neglecting to prepare properly can result in paint peeling, cracking, and premature failure. By investing time and effort into the preparation process, you lay the groundwork for a beautiful and long-lasting paint job. We have many jobs around Eau Claire where we spend more time on preparation than we do on actually painting the house – the importance of this time spent cannot be understated.

Planning a Paint Job

Before starting any exterior painting project, careful planning is the next most essential part of a successful paint job. Determine the best type of paint for your project, the areas to be painted, and the colors you desire. Look ahead at the weather and make sure it is dry and warm enough for the work to be completed end to end, as exterior painting is best done in our warmer months in Wisconsin when the temperature is high and humidity is low. Proper planning allows us to gather the necessary tools, materials, and paint, ensuring smooth and efficient painting days.

Pet Control

If you have pets, it’s crucial to consider their safety during the painting process. Keep them away from the work area by confining them to a separate part of your home or arranging for them to stay with a friend or family member. Paint fumes and wet paint can be harmful to pets, so it’s best to keep them in a safe and comfortable environment until the project is complete. It’s also a hazard on the jobsite because an errant dog or cat can easily disrupt a painter on a tall ladder. Because we always strive for as close to perfection as we can get, we never want the unknown factor of a family pet around strangers.

Ladders and Scaffolding

To access all areas of your home’s exterior, you may need ladders or scaffolding to reach high eaves or fascia boards. Safety is always a priority when working at heights. Always ensure that your ladders are in good condition, stable, and placed on a flat surface. If using scaffolding, follow the manufacturer’s guidelines and secure it properly – don’t let it hang about without being anchored. Exercise caution and work with a partner whenever possible to ensure stability and minimize the risk of accidents. Use safety harnesses as necessary, especially if you decide to paint from the rooftop.

Exterior Paint Ground Cover

Protecting the surrounding areas from paint splatters and spills is an important part of the prep work. Use drop cloths or plastic sheets (which you can buy locally) to cover the ground, plants, landscaping, and any surfaces you absolutely do not want to be accidentally painted. This precaution minimizes cleanup and safeguards your property from potential damage. Pro tip: It is easier to park your car across the street than it is to cover it fully with painter’s plastic. If you have the opportunity to remove valuables, we will always recommend you do it – just in case.

Trimming Back Your Plants

Before initiating your exterior painting project, it is essential to carefully trim any nearby plants, shrubs, or trees that may bump against your house. By pruning foliage, you prevent interference with the painting process, ensure convenient access to the surfaces, and minimize the risk of paint transferring onto the plants. Additionally, trimming overhanging branches creates an unobstructed workspace, facilitating more efficient and precise painting. We will always try to point out the areas that may need a trim during the estimating process, and we will always do our best i​​f there is some tree or bit of foliage that you don’t want cut.

Monitoring Weather Conditions

There is a reason that all of our exterior painting happens in the summer. Weather conditions significantly impact the success and longevity of an exterior painting project. It is crucial for us all to closely monitor the weather forecast before and during the painting process. Ideally, the weather is dry, with several consecutive days of fair conditions projected. Avoid painting on excessively hot or humid days, as these conditions can affect paint drying and result in uneven finishes. By choosing appropriate weather conditions, you promote optimal paint adhesion and achieve a seamless outcome.

Sanding the Exterior

Sanding is a critical step in the preparation process as it smooths out rough or uneven surfaces, removes loose paint, and promotes better paint adhesion. Use a power sander or sandpaper to carefully sand the exterior surfaces, paying close attention to areas with peeling or flaking paint. After sanding, thoroughly clean the surfaces to remove dust and debris before moving on to the next step.

Cleaning the Exterior Surface and Removing Contaminants

Thoroughly cleaning the exterior surface is imperative for proper paint adhesion and a flawless finish. Prior to commencing painting, meticulously wash your home’s exterior to eliminate dirt, grime, mold, mildew, and other contaminants. Employ a pressure washer or a garden hose with a nozzle attachment, using a mild detergent or specialized cleaning solution. Pay close attention to areas prone to buildup, such as eaves, gutters, and corners. A clean surface not only enhances paint adhesion but also ensures vibrant, long-lasting results.If you are signed up with Al’s Painting, we will take care of this for you on your behalf to make sure we are delivering a strong, lasting product.

Caulk Gaps, Patch Holes, and Find and Replace Wood Rot

Inspect your home’s exterior for gaps, cracks, holes, or signs of wood rot. Use high-quality exterior caulk to seal any gaps or cracks, preventing water intrusion and creating a seamless surface. Employ an appropriate patching compound to repair holes or damaged areas. If you discover wood rot, address it promptly by replacing the affected wood to maintain the structural integrity of your home and ensure a smooth painting surface.

Protecting Non-Paintable Surfaces, Windows, and Doors

Safeguarding non-paintable surfaces, windows, doors, and other vulnerable areas during the exterior painting process is essential. Utilize plastic sheets, drop cloths, or masking paper to cover these surfaces, securing them with painter’s tape. Taking this precautionary step ensures that paint is applied exclusively to the intended areas, minimizing the need for extensive cleanup afterward. Protecting these surfaces preserves their appearance and minimizes the possibility of unnecessary touch-ups or repairs.

Priming for Paint

Priming is a crucial step in the preparation process, particularly when painting over bare wood or previously unpainted surfaces. A high-quality primer creates a smooth and uniform surface, improves paint adhesion, and enhances the overall durability of the paint job. Apply a coat of primer using a brush or roller, following the manufacturer’s instructions. Allow the primer to dry completely before proceeding to the final step.

Painting Time

Finally, it’s time to apply the paint to your home’s exterior. Choose a high-quality exterior paint suitable for your specific surface type and desired finish. Begin by cutting in around windows, doors, and other edges using a brush, then use a roller or sprayer to cover larger areas. Apply the paint evenly and in thin layers, allowing sufficient drying time between coats. Multiple coats may be necessary to achieve the desired color and coverage. Take your time and ensure the paint is applied smoothly and evenly for a professional-looking finish.


Preparing your home for exterior paint requires following a series of crucial steps that establish the groundwork for a successful and long-lasting paint job. Whether considering hiring a professional or DIY, each step contributes to achieving a seamless and professional finish.
