Can You Spray Lacquer Over Latex Paint? [Answered!]

Lacquer is a great solution if you’re looking for something to add an extra layer of protection to the surface. But what if the surface is latex-painted? Can you spray lacquer over latex paint?

Yes, it’s 100% okay to spray lacquer over latex paint but only if the paint comes with no sheen. Unlike oil-based paints, lacquer paint has better bonding qualities. But make sure you don’t apply too much lacquer to the paint because there’s a chance for the paint to blister or wrinkle.

Also, there are a few crucial factors you must know instead of jumping to a conclusion. So, let’s keep reading and find the necessary information.

Can You Spray Lacquer Over Latex Paint?

There has been a lot of debate lately on whether or not you can spray lacquer over latex paint. The answer is, it depends. 

If the latex is flat with no sheen then you can spray lacquer over it. If the latex has sheens and you spray lacquer directly, the rapidly evaporating solvents in lacquer may damage the latex. In addition, the lacquer may crack over time. 

Some fixative chemicals are used to give sheens to latex paints. These chemicals react negatively to lacquer causing wrinkles when it is applied over. With flat latex paints, there are no such chemicals and you can spray lacquer on safely.

Will Lacquer Stick to Latex Paint?

Many people are concerned about how well lacquer will stick to latex paint. Unfortunately, this is a common question that doesn’t have a simple answer. There are many factors that can affect how well lacquer will adhere to latex paint, such as the type of lacquer, the quality of the latex paint, and the surface on which the lacquer is being applied. In general, though, most lacquers will stick to latex paint if it’s applied in a thin layer and if the surface is clean. Test a small area first to make sure that the lacquer will adhere before applying it to a large area.

Spraying Lacquer Over Latex Paint: Instructions

  • For best results first spray some flat latex, thinning them with 10% water, and then spray the lacquer over. 
  • If you insist on spraying lacquer over latex with sheens make sure to use primers to avoid any problems. We recommend using Sherwin Williams shellac-based primers. They contain all types of finish including latex and roof emulsions. 
  • Also, check with your supplier to be sure about the correct primer. In addition, before bedding in your lacquer, make sure you are using a waterborne version of the lacquer finish. 
  • Don’t spray too much lacquer at once. If the lacquer is too thick or too harsh it may wrinkle or blister the latex paint. Apply multiple thin coats from a reasonable distance. 
  • Usually, latex paints should be coated with a minimum of two coats, but three or even four coats are usually better. It’s important to allow the first coat to dry completely before applying a second coat. For latex, letting each coat sit for at least three hours is recommended.
