Paint TechTalk with Lettie: Can I Paint Permacoat Latex Over Acrytex Primer?

Hi, Lettie.

I primed my concrete with Boysen Acrytex Primer. But now I want to use Boysen Permacoat Latex as a topcoat finish. Is this okay?

Thanks.

Hi, Boysen User P.

Thanks for your inquiry!

The answer to your question is yes. Generally, you can apply Boysen Permacoat Latex on top of a surface that has been primed with Boysen Acrytex Primer.

It all boils down to paint compatibility. You did the right thing by making sure that your primer and topcoat are compatible with each other. Because, as you may already know, certain paint products when used together or in the incorrect order will cause paint problems.

For example, working with both a solvent-based paint, like Acrytex, and a water-based paint, like Permacoat, on the same surface can be a bit tricky. Typically, a water-based paint can be applied on top of a solvent-based paint. You cannot, however, apply them the other way around—such as using a water-based primer then a solvent-based topcoat. This will cause a paint problem called saponification or kumukulong pintura.

You’ll notice saponification on your walls when the paint you’ve applied does not seem to dry. When you touch it, the paint will feel sticky or tacky even days after you’ve finished painting. You might even notice it as you’re painting—the paint you’ve just applied doesn’t seem to sit right or isn’t as smooth as it should be.

The easiest way to ensure that all the products you’re using for your project are compatible with each other is to follow a product’s painting schedule.

Each Boysen paint product will have a manufacturer-recommended painting schedule. The painting schedule is essentially a quick guide for the other necessary products that are compatible with your already chosen product and the sequence in which they’re to be applied—in short, it’s a cheat sheet.

If you would, however, like to use different products together, such as what you intend to do with your painting project, it’s always best to consult with the manufacturer as there might be issues with paint compatibility. So, good job doing so!
