Many homeowners have asked this question at some point or another, “can interior paints be used on exterior surfaces?” However, the answer, as it turns out, is complicated.
Certain paints are specifically designed for exterior use, and these will perform better in harsher weather conditions. But if you’re careful and choose the right kind of paint, you might get away with using interior paint on the exterior of your house.
Let’s discuss some vital information to help you fully realize your options.
Things To Consider Before Using Interior Paint on Exterior Surfaces
The Type of Paint
When selecting the right paint for an outdoor project, it is essential to consider factors such as waterproofing, UV protection, and fade resistance.
Different kinds of interior and exterior paints include:
- Latex and acrylics: These paints are great for exterior painting because they offer excellent durability and resistance to moisture.
- Oil-based paints: These paints provide an extra layer of protection, so they are often used on the exterior of houses. They are long-lasting and perfect for areas with high temperatures or humidity.
You should also consider the durability of the paint. Exterior paints are formulated to last longer, even on surfaces exposed to water, wind, and extreme temperatures.
Interior paints may not have the same staying power outside and could easily chip or peel under weather conditions.
Using interior paint on an exterior surface may be cost-effective in the short term. Still, it can be more expensive over time.
It’s because interior paints are typically cheaper than professional-grade exterior paints and require less preparation. However, they will likely need repainting more often due to their lower durability rate.
Using a good primer before applying exterior paint is essential for making sure your surface is properly prepped before painting. Primers provide an extra layer of protection over the existing surface and help ensure your coating adheres correctly.
Whereas interior painting may not require professional priming services, exterior painting typically does need professional care to ensure an excellent finish.
Consequences Of Applying Interior Paint to The Exterior
Interior paints won’t stand the same level of wear and tear as exterior paint. They may chip or peel more quickly and won’t provide adequate UV protection – an essential factor in the longevity of your home’s exterior.
Additionally, interior paint is not designed to be waterproof, meaning moisture and humidity can cause damage over time.
Why Are Water-Based Paints the Best for Exteriors?
A professional painting contractor will generally recommend using water-based exterior paints if you plan to paint your house’s exterior. These paints are highly durable and weather resistant.
They can also withstand harsh climates, fluctuating temperatures, and UV rays without fading or chipping away.
Water-based paints dry quickly compared to oil-based paints and don’t have a strong odor like oil-based products. They come in various colors, so you can find one that perfectly matches the look and feel of your home’s exterior.
How To Plan Your Next Exterior Painting Project?
Before you begin your painting project, consider a few things. First, ensure that the surfaces you are painting are adequately prepared by removing all dirt, debris, and any old paint that may be flaking off.
Before applying paint, you should also seal the surface with primer. This will help protect it from water damage and give it an even finish when finished. Additionally, you’ll want to use professional-grade tools and materials throughout the process for the best results.
Choosing the correct exterior paint for your house’s exterior is also important. Different paints have different features, so research which one best suit your needs.
Why Should You Avoid DIY Painting and Hire a Professional Painting Contractor Instead?
Quality painting and professional techniques are essential for a professional-looking finish. Attaining the desired results requires special tools and experience, so DIY painting is not ideal nor recommended if you want to achieve professional-level results.
A professional painting contractor can advise you on which paint type and brand will best suit your home’s exterior based on the local climate, weather conditions, your house’s siding material, and more.
Equipment, Tools, And Safety
A professional painting contractor will have the right equipment, tools, and safety gear to paint your house’s exterior properly. Without proper tools and safety gear, you can risk not only the quality of the job but also potential injury.
Professional painting contractors typically follow a set process to complete the job on time while ensuring the best results. DIY painting may take longer than expected due to a lack of knowledge or experience in professional techniques.
Most professional painting services offer warranties that cover any future defects caused by improper application or faulty paint materials. With DIY painting, you won’t get such protection if something goes wrong with the paint job.
Professional painting services will thoroughly inspect your home’s interior and exterior before beginning the job to ensure everything is in order. DIY painting doesn’t always guarantee a thorough inspection, which could lead to problems.
Professional painting services may initially appear more expensive than DIY painting. Still, they offer better value in the long run due to superior results and fewer potential problems.
DIY painting can be dangerous if proper safety measures are not taken. Professional painters have the knowledge and experience to work safely on ladders, roofs, and other heights with professional-grade safety equipment.
Interior and exterior paints differ in their properties and should not be used interchangeably. Hiring a professional painting company is your best option to ensure quality results and safety when painting your home’s exterior or interior.
