Is Exterior Paint Thicker Than Interior Paint?

Why is exterior painting thicker than interior painting? It is due to the additional additives needed to keep the paint resistant to weather. Decorative paint for the exterior of your home is more decorative, and exterior paint can be harmful indoors. Learn more about the differences between interior and exterior paint and how they can impact your home. And don’t forget to read the manufacturer’s instructions to determine whether your chosen paint is safe to use indoors.

Alkyd paint

Most house painters use alkyd exterior paint. The thicker texture is good for covering large areas. However, many homeowners find that the cost of alkyd exterior paint can be prohibitive. However, there are many benefits of using alkyd house paint. The paint will last longer than other types of paint. It is also more resistant to scuffing than other types of paint. Moreover, it is easier to apply than latex.

The only downside of alkyd exterior paint is the fact that it may oxidize on exterior surfaces exposed to the sun’s ultraviolet rays. However, it will not chalk or crack over time. Compared to latex paint, alkyd exterior paint is much less likely to peel off. It is also much easier to apply a second coat. However, the paint may need solvents to dry after the first one.

Another benefit of alkyd exterior paint is its ability to resist moisture. This property makes it ideal for use in bathrooms and hallways, and it is also resistant to fading. Because of its moisture resistance, alkyd paint is also suitable for kitchens and bathrooms. In fact, Valspar Signature is a popular brand for these areas. It is a highly durable paint and can be applied to a variety of surfaces.

Alkyd exterior paint can be applied over both latex and unfinished wood. It is easier to apply than latex, which makes it an excellent choice for bathrooms. Alkyd exterior paint requires fewer preparations than other types, such as stripping old paint. On the other hand, it can be more toxic to the environment than water-based paints. It also tends to spatter more and needs greater care to apply than latex paint.


One of the biggest differences between interior paint and resin is the thickness of resin. While both types of resin are thick, low-viscosity resins take longer to dry and cure. They can be worked with while they are still a liquid, but once cured, they must be completely dry before applying a final coat of resin. Because the wide range of brands of resins is so large, it can be difficult to choose the best one for your project. Here are a few to consider:

The thicker consistency of resin makes it ideal for wall coatings, such as faux-finishing. They are also a better choice for outdoor use, but aren’t ideal for precise coloring. Additionally, they may fade over time or fade when exposed to ultraviolet rays. Because they are thicker than traditional paints, you should be cautious when applying them outside. As they dry to a grainy, stone-like finish, resin may not be the best choice for outdoor use.

ArtResin epoxy resin bonds well to nearly any surface, except plastic, wax paper, and natural objects that repel water. ArtResin epoxy resin is a good choice for paintings, sculptures, and other art projects. It’s flexible enough to cover wood and tile, but not for carved or raised surfaces. It’s also great for jewelry projects. The epoxy resin is a bit thicker than interior paint and may sag.

To apply resin, gather all materials needed close by. Make sure to protect the surrounding area with plastic sheeting or a tarp. You must make sure that the area is completely clean and dry, as resin can leak out of wood. Also, remember to lightly sand the surface, as the resin will be harder to apply if it’s not perfectly smooth. For best results, mix the resin well.


While most interior and exterior paints are considered “waterproof,” exterior paints must meet the American Society for Testing and Materials’ (ASTM) standards. ASTM specifies various criteria for quality and performance, including aesthetics, ease of application, and durability. Sherwin-Williams develops interior paint to meet these standards. Its latex paint, for example, is extremely durable and can be cleaned with soap and water and light scrubbing.

The quality of exterior paint is often surpassed by its price, so premium brands are often more expensive than budget-friendly versions. Popular brands of premium exterior paint include A-100 and SuperPaint, which can be applied in temperatures as low as 35 degrees. These products are made from premium ingredients and offer greater durability and long-term protection. Listed below are some advantages of using premium exterior paint. These paints will last longer and look better.

Exterior paint contains heavier-duty resins to withstand harsh weather. They also contain additional additives to prevent fading, inhibit mildew, and resist tannin staining. In addition, interior latex lacks these additives, so it is less likely to scuff and fade over time. This means it should be avoided if you are allergic to mildew. Also, consider the paint’s VOCs.

In addition to these premium pigments, exterior paints are often made thicker and longer-lasting by adding extender pigments. These ingredients add weight to the paint and control its gloss. Some extenders also provide additional film performance. Clay, talc, and silica are common extenders. They offer increased durability and scrub resistance, while silica is excellent for reducing abrasion.


If you’re thinking of painting the exterior of your home, you’ll probably want to consider the cost of exterior paint, which can be anywhere from $15 to $80 per gallon. The difference in price reflects the thickness of the paint and its finish. Exterior paint has a softer resin, making it more durable against scratches, scuffing, and sunlight, while interior paint is thicker and more rigid. Exterior paint can also be more toxic to the environment because it releases more volatile organic compounds, or VOCs, when it cures, compared to interior paint. Some of these chemicals are so toxic that you can’t even use them indoors, and the smell can trigger allergies and asthma.

When it comes to selecting paint, you can purchase a wide range of brands. You can buy a low-cost paint with a basic consistency, and you can upgrade to a more expensive brand if you want. Exterior paint is generally thicker than interior paint, but the price difference isn’t very significant. You can buy a thicker, more durable paint that is also waterproof. It’s possible to buy a higher-quality product that’s a bit pricier, but it’s best to stick to your budget.


There are a few important differences between interior and exterior paint. While the former is thicker, interior paint is thinner. The difference in paint thickness between these two types is most noticeable in the appearance of the paint on the exterior of the home. Exterior paint is also more durable and resists the effects of UV rays and environmental factors, while interior paint is more suitable for interior applications. Exterior paints also tend to be more pigmented than interior paints, making them easier to apply to the exterior of a building. Exterior paints are also often more flexible, which is why they are used on wooden cladding, fences, and decking.

Moreover, interior paints are designed to resist staining and mildew, while exterior paints are made to be more stain-resistant and easy to clean. Despite these differences, all paints are made from the same basic components: solvents, pigments, and resins. All these factors play a significant role in the thickness of the paint, so make sure you choose one that has the right thickness and quality for your home.

When it comes to color, there are many differences between interior and exterior paint. Interior paints are more durable and can hide brush marks, while exterior paints are more likely to fade with time. Exterior paints are designed to be resistant to the elements, while interiors are designed for a more controlled environment. For example, interior paints are usually low-VOC, which reduces the risk of exposure to harmful fumes. And because interior paints are often touched and werehed, they have a longer shelf life than interior paints.

While interior paints are made with a solvent, exterior paints contain more resin. This resin is what gives exterior paints their durability. This resin is a natural ingredient in the paint, and it will outgas during the first 48 hours after painting. This process helps the exterior paint resist chipping and fading. If you’re concerned about how exterior paints are different from interiors, consider hiring a professional to help you.
