Most homeowners choose exterior house painting to revamp their property. It is a hassle-free and cost-effective home improvement project that enhances curb appeal and perceived value. A new coat gives your home a fresh look and appeals to your neighbors and future buyers. It protects the home against external elements and prevents structural damage. 

Many DIY homeowners start the project with excitement, but become frustrated when the color and finish do not match their desired results. They often make preventable mistakes such as choosing the wrong paint, failing to prepare and prime the surface, and failing to protect the landscape. Such mistakes affect the appearance and durability of paint and waste your time and effort on the project. This blog highlights the mistakes homeowners must avoid to get a higher return on their investment and enhance the appearance and value of their property.

Mistake #1: Skipping proper surface preparation

The most costly mistake happens even before the paint touches the surface. A thorough surface preparation creates a stable base for paint to adhere to. Applying paint to dirty, peeling, or damaged surfaces causes uneven application and premature peeling. Dirt, mildew, cobwebs, and loose paint often create a barrier, affecting adhesion. 

Solution

Clean the surface thoroughly with a pressure washer or mild soap. Scrape off old, flaking paint and sand rough areas. Fill any gaps with sealant or caulk, use a primer, and check if the surface is dry before applying paint. 

Mistake #2: Choosing the wrong type of paint

Exterior paint is formulated to withstand rain, UV rays, physical wear, and temperature changes. Most people make the mistake of purchasing paint solely based on color and price alone. They do not factor in the durability and performance of different kinds of paint. 

Cheaper paint does not last long, and the cost of repainting is higher than investing in high-quality paint in the first place. Not considering the quality and formulation of paint affects the results and also increases the hassles and cost of repainting.

Solution

Consider your local climate when choosing paint. Desert environments require a different formulation than coastal or humid areas. Choose exterior paint that includes UV blockers, mildew resistants, and resins that expand and contract with temperature changes.

Mistake #3: Applying paint too thinly or too thickly

Applying a too-thin or too-thick layer of paint can ruin the finish. Most people only apply a single coat to finish the project quickly. A single coat does not cover imperfections, fades quickly, and does not protect against weather elements. A thick coat, on the other hand, drips and sags, creating an uneven finish. It also leads to cracking and peeling as the top layers dry faster than the bottom. 

Solution

Proper paint application techniques provide consistent color and sheen, prevent lap marks, and help paint cure evenly. Apply two thin coats for proper color development and even drying. 

Use angled or straight-edge brushes with synthetic bristles for smooth strokes and the right amount of paint application. Apply paint in controlled, even strokes, focusing on small sections at a time.

Mistake #4: Skipping caulking or sealing

If there are cracks or gaps on the surface, sealing and caulking are non-negotiable. Caulking prevents moisture intrusion, mold growth and improves the appearance of paint. Most homeowners neglect areas like window trims, door frames, and siding joints when caulking, leaving the exterior with an imperfect finish. 

Solution

Choose exterior-grade caulks to seal and create a smooth surface before painting. 

Mistake #5: Failing to protect landscaping and fixtures

Plants, walkways, and fixtures can get permanently damaged by paint overspray and drips. It costs far more to repair the damage than to prevent it. Homeowners avoid using masking tape and plastic sheeting to lower expenses, but end up spending thousands to repair damaged landscaping and fixtures. 

Solution

Homeowners must spend significant time covering up the surrounding surfaces and protecting them from paint. Make sure to completely cover air conditioning units, outdoor furniture, and lighting fixtures. 

Mistake #6: Neglecting safety precautions

Many homeowners do not get the right tools and safety gear to complete the project, and end up harming themselves and damaging the property.

Solution

Use a proper ladder to reach higher surfaces, and do not rely on unstable surfaces. Wear gloves, a mask, and eyewear to protect against paint drips and fumes. Read the instructions to handle paint, solvents, and equipment correctly to avoid chemical reactions and accidents.
