Hi, Lettie.

For my new exterior concrete wall, we unintentionally applied Boysen Permacoat Flat Latex instead of Boysen Acrytex Primer. How do I fix this? I want to use Acrytex.

Thank you.

Hi, Painter J!

I’m happy that you thought to message Paint TechTalk with Lettie before moving forward with your project. Otherwise, you would probably be dealing with a major headache right now! You’ll see why in a bit.

For now, I’ll have to be the bearer of bad news. To be able to use Boysen Acrytex, you will have to strip your wall back to bare concrete. You will need to remove the Boysen Permacoat Flat Latex you’ve already applied.

And when that’s done, you start over and apply Boysen Acrytex Primer this time around. Then you can move on to putty and topcoat.

The reason you have to start over? Paint incompatibility. As paint products differ in formulation from each other, it follows that some of them cannot go together.

In this instance, when you apply Boysen Acrytex, which is a solvent-based paint, over Boysen Permacoat Latex, which is a water-based paint, you get every painter’s nightmare—kumukulong pintura a.k.a. saponification.

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.

So, it’s a good thing you sent your inquiry when you did!

Are you planning on using Boysen Acrytex for your topcoat? Moving forward, if you’re ever unsure of what products can go together, check the painting schedule. It tells you what primer and putty to get.

A painting schedule is essentially a quick guide for the other necessary products that are compatible with your preferred one. Think of it as a cheat sheet. Every Boysen product comes with one. Just check Boysen.com.ph! The one for Boysen Acytex is shown above.

Taking a look at the painting schedule before you start your project can save you a lot of trouble.

Hoping everything goes smoothly with your project from this point on. Good luck!
