Can Interior Paint From Valspar Be Used Outside?

Paint expert Ray Brosnan suggests that while it is generally not recommended to use interior paint on exterior surfaces, there are some instances where it may be feasible. These include repurposing leftover interior paint for small, low-impact outdoor projects, and using door paints and trim paints that are specially formulated for both interior and exterior use. However, it is important to note that interior paint does not offer the same level of durability and weather resistance as exterior paint, which contains special additives like heavy-duty weather-resistant chemicals and mildewcide to withstand heat, cold, snow, rainfall, and the sun’s rays.

Using interior paint outside is not recommended due to its lack of durability, weather resistance, and UV protection. It is best to invest in high-quality exterior paint for long-lasting and visually pleasing results. If a renovation or addition has changed an exterior wall to an interior wall, you can confidently paint over exterior paint with interior paint. However, using interior paint on outdoor surfaces might lead to serious disappointments, such as peeling and voiding.

It is crucial to use products as labeled, as interior paints are not usually designed to withstand the sun’s rays, bad weather, or contraction and expansion cycles of exterior surfaces in changing temperatures. Exterior paints are not evaluated for indoor air conditions and contain extra additives like anti-mould and other compounds that off-gas, which can be harmful to health.

To use interior paint on exterior surfaces, properly prepare walls and ceilings, including previously painted and primed plaster, wood, brick, drywall, cement, and metal. Valspar Interior/Exterior High Gloss Enamel can be used to prime interior bare surfaces before applying the finish coat. Both manufacturers and pros recommend using each can as labeled, as interior paints inside and exterior paints outside are not recommended.

What can I add to interior paint to make it exterior?

Exterior paint is designed for outdoor environments to handle extreme temperatures and be flexible enough to withstand significant temperature changes. Its binding resins allow coverage to expand and contract without peeling or chipping, while additives help resist staining, mildew, and fading. Interior paint can be transformed into a durable exterior paint by combining it with an Outdoor Additive by The Real Milk Paint Co. Outdoor paint also has a formulation that promotes better coverage on rougher surfaces, but it contains more VOCs than interior paints, making it suitable only in highly ventilated areas.

Outdoor paint comes in flat, gloss, or semi-gloss enamels, making it limited in color choices. Painting techniques and surfaces also differ, with some jobs requiring scraping away old paint before application.

Can I mix interior paint with exterior paint?

The application of interior and exterior paint in a single coat can result in poor adhesion, which may manifest as peeling, flaking, or cracking. Furthermore, it can result in an uneven coloring and finish due to the presence of varying gloss and texture levels. Furthermore, exterior paint contains elevated levels of volatile organic compounds (VOCs) relative to interior paint. This may pose potential health risks if applied within indoor environments. It is therefore imperative to refrain from mixing paints.

What happens if I use interior paint outside?

Interior paint used on an exterior surface can cause aesthetic flaws due to its inability to withstand exterior elements, leading to cracking, blistering, bubbles, and peeling. It is not recommended to use interior paint on an exterior surface as it may not last long. Repairing this damage requires sanding the paint off the substrate, sealing with an outdoor primer, and repainting the entire area with the appropriate outdoor wall paint.

This can be time-consuming and costly. If an accident occurs and indoor paint is used outdoors due to a wrong label, applying 1 or 2 coats of outdoor paint immediately after drying can save the paint.

Can interior wall paint be used outside?

Interior paint is not durable enough to withstand outdoor elements like wind, rain, and sunlight, leading to color fading, peeling, bubbling, and cracking. The best exterior paint for exteriors is oil-based and latex, which can cover various materials like stucco, brick, aluminum, wood, and rust on outdoor furniture or fences. These paints should not be used outside, as the hard work put into the paint job may be wasted in just a year.

What is the difference between exterior paint and interior paint?

Interior and exterior paints have distinct compositions, with exterior paints designed to withstand environmental conditions like UV rays and temperature fluctuations, while interior paints prioritize low VOC levels for indoor air quality and resistance to scuffs and stains. Exterior paints contain softer binding resins and additives for flexibility and UV resistance, while interior paints use rigid resins for durability and often feature lower VOCs for health safety.

Choosing the right type of paint is crucial, as using interior paint outdoors can lead to finishing issues like cracking and peeling, while using exterior paint indoors can pose health risks due to higher VOC content and inappropriate formulation for confined spaces. Understanding these differences is essential for maintaining the aesthetic and structural integrity of a painted surface and choosing the right product for the right place, whether you’re planning to refresh a single room or revamp the entire exterior of your home.

In conclusion, understanding the differences between interior and exterior paints is crucial for maintaining the aesthetic and structural integrity of a painted surface and choosing the right product for the right place.

Can Valspar interior paint be used outside?

It is crucial to use products as labeled, as interior paints are not designed to withstand harsh weather conditions or the contraction and expansion cycles of exterior surfaces. However, if a product is labeled “Interior/Exterior”, it can be confident of its performance in both environments. The right brush or roller can make a significant difference in a paint project, and if you’re unsure which one to use, give your brushes a little TLC to ensure years of service.

For latex paint, remove excess paint while it’s still wet. For dried paint, use a brush comb and wash off the remaining paint under running water. Oil-based paint should be removed with mineral spirits, rinsed in tap water, and washed with soapy water. Rinse the brush until the water runs clear.

Is there really a difference between interior and exterior paint?

Different paints have different properties due to their manufacturing purposes. Exterior paint is designed to handle mildew and fading, while interior paint is designed for cleaning and stain resistance. Understanding the difference between these two types requires understanding the chemistry behind each type. All paints are formulated from the same basic ingredients, including resins, additives, solvents, and pigments.

How long will interior paint last on the exterior?

Outdoor interior paint may need repainting after a year or two, depending on the area’s exposure. Consider sealing it with weather-resistant sealer or waterproof paint at Walmart.

Do you need special paint for outside of house?

The best exterior paint is designed to withstand harsh weather, sunlight, and varying temperatures, making it essential to choose the right formula for your home. It’s crucial to paint in the right weather, as most paint won’t dry completely in temperatures colder than 50-degrees Fahrenheit. In warm temperatures or direct sunlight, paint may dry too fast, causing lap marks. Wind, rain, and humidity can also affect drying time and appearance. Extreme cold or hot climates may require a special paint formula.

Water-based paint is faster than oil-based paint, so it’s a good option for those in a time crunch. Before applying a larger amount, purchase a small sample of the new color and wait a day or two to let it settle.

Why is exterior paint cheaper than interior paint?

There are two main types of paint: interior and exterior. Exterior paints are more expensive due to their added ingredients for toughness, moisture resistance, and UV color corrosion. Interior paints are more basic and less expensive. Paint finishes can range from flat to high-gloss, and the choice of finish doesn’t affect the cost. The four typical finishes are Flat, Eggshell and Satin, Semi-Gloss, and Gloss.

Professional paint testers look for specific qualities in paints before they are available for purchase. Before being available for purchase, paints undergo rigorous testing to ensure they meet the necessary standards.

Can latex paint be used outdoors?

Latex paints are easier to work with, go on easier than oil, are nearly as durable, and can be cleaned with water. They can be used on any surface, even metal, but they don’t dry as hard as oil. If you choose latex paint, choose an exterior one, not an interior one. If your home was previously painted with oil-based paint, use oil-based paint again. To determine if the paint was used, peel a small chip of old paint off your house and examine it. If it’s very hard and unbending, it’s likely oil-based.

If you try to apply latex over an old oil-based paint, the latex will peel off, rendering your efforts useless. If you need a professional to handle your exterior painting job, KrystalKlean’s pros can help.
