Are you in the process of sprucing up your home exterior? Maybe you’re considering adding a fresh layer of paint on your walls, but you’re unsure if you can paint elastomeric paint over your existing latex paint. Well, put your worries to rest because I’ve got the answer for you.
Many homeowners wonder if elastomeric paint can be applied over latex paint. The good news is, it can! You don’t have to remove your existing latex paint before applying the elastomeric paint. However, it’s essential to know a few things before you start painting.
Firstly, elastomeric paint is a high-build coating that provides excellent waterproofing and protection against the elements. It’s ideal for use on a variety of surfaces, including concrete and stucco. Secondly, before applying the elastomeric paint, make sure the surface is clean and dry. Any chipping or peeling areas must be repaired before painting. With these simple tips in mind, you’ll be on your way to a smoother and more durable finish in no time!
Differences between Elastomeric paint and Latex paint
Elastomeric paint and latex paint are two popular types of paint used in many different applications. However, there are significant differences between them, including:
- Elasticity: Elastomeric paint is designed to expand and contract with the surface it is applied to. This makes it ideal for surfaces that are prone to movement, such as concrete and stucco. Latex paint, on the other hand, does not have the same elasticity and can crack or peel over time on surfaces that are prone to movement.
- Thickness: Elastomeric paint is much thicker than latex paint, typically five to ten times thicker. This thickness makes it ideal for covering cracks and imperfections in the surface being painted. Latex paint, while it can also be used to cover imperfections, does not have the same thickness and may require multiple coats to achieve the same level of coverage.
- Water resistance: Elastomeric paint is highly water-resistant, making it ideal for use in areas that receive a lot of moisture, such as exterior walls and roofs. Latex paint is also water-resistant, but not to the same degree as elastomeric paint.
- Coverage: Because of its thickness, elastomeric paint typically covers more area than latex paint. This means that you may need fewer gallons of elastomeric paint to cover the same surface area as you would with latex paint.
