Oil Over Latex or Latex Over Oil?

One of the most common mistakes in painting is applying oil over latex paints. Although, despite this simple rule, it can raise other concerning factors: can you use a waterborne alkyd over latex paint and vice versa? And if so, does it require a primer? Today we will discuss these concerns as well as give a quick tutorial on how the process should be executed. If you have any questions about this blog or any other paint related inquiries, please contact your local Houston Interior Painting?experts, Pro Painters, for additional information.

Sometimes it can be difficult to determine if it?s safe to apply oil paint over latex paint, but we assure you, overtime it will ruin your surface. Due to the flexible qualities of latex paint and the brittle characteristics of aged oil paint, it can eventually split and crack the painted surface. Another concern is whether or not it?s safe to apply waterborne alkyds over latex. Waterborne alkyds are a low-VOC paint that provide a clean durable finish and are mainly used for wooden cabinetry. They are available in odor-free options and can safely be applied over latex paints. Although, perhaps one of the best features about alkyds aside from providing protection to your surface, is that you rarely have to apply a primer on top.

If you plan on using waterborne alkyd paint over latex paint we first suggest that you thoroughly clean the surface you will be working with. This is a key factor. The surface must be free of all dust and grime as well as any wax, oil, grease, or mildew. In addition, try your best not to have any soap or water soluble materials left over from the cleaning. You want it to be bone dry. If there are any peeling flakes or blemishes in the surface, you?re going to need to properly sand off these areas so everything is clean, crisp, and uniform. Next, begin applying your alkyd paint. It is best to use a nylon/polyester brush or roller. Also, you should consider setting up additional ventilation in your work area to ensure that the paint dries rapidly.

Painting can be fun and easy, but it is always good to thoroughly research the materials you will be working with. In addition to understanding the safety information, it will help you prevent any possible future damages to your surface. And remember, never apply oil paints over latex unless you are using a waterborne alkyd which will safely coat the more flexible layer beneath. Although, to fully ensure the job is done right, we highly recommend you utilize the expertise of a Commercial Painting Contractor.
