Hi, Lettie.

I have exteriors that are already painted with Boysen Acrytex. It has lasted me a long time but now I’m planning to repaint it. I’ll be using Acrytex again but I have a few questions that I hope you can answer.

First, what is the procedure for painting Acrytex over Acrytex? Do I have to scrape my old paint? Second, can I apply a skimcoat over my old paint and then apply the new Acrytex?

Thank you very much in advance for your help. Looking forward to your response!

Hi, Boysen User J!

Thanks for your message. I would be happy to answer your questions on Boysen Acrytex! Boysen engineers formulated it to be extremely durable and long-lasting, so hopefully this was true for you and will be true again.

Repainting Acrytex Over Acrytex

Paint TechTalk with Lettie: How Do I Repaint Over My Acrytex Exteriors? | MyBoysen

Alright, let’s start with your first question. You don’t have to scrape if your existing paint is in good condition. This means that you don’t see flaking, chalking, blistering, and other paint problems. Painting over such problems will likely just ruin your new paint. Sayang naman.

So, if your old paint is in good condition the first thing to do is to clean it. After, sand the surface lightly using sandpaper so your new paint can adhere properly to the surface. Remove the excess dust and make sure the surface is dry before you start painting.

Now you can start painting. If your existing paint color is darker than the new one, apply one coat of Boysen Acrytex Primer. If not, you can go straight to using Boysen Acrytex Topcoat. Apply two coats and you’re done!

Using Skimcoat with Acrytex

Moving on to your second question. The answer is no, you cannot apply skimcoat over your existing paint. Skimcoats are meant to be applied on bare concrete only. This means that if you would like to correct imperfections using skimcoat, you would have to strip back to bare concrete first.

If you’re set on using skimcoat and are prepared to strip to bare, I recommend Konstrukt Permaplast K-201 High Performance Acrylic Skimcoat. This product is compatible with the Boysen Acrytex system.

However, if the imperfections on your surfaces are less than 1mm, consider using putty instead! It’s enough to correct those. I recommend Boysen Acrytex Cast for your exterior concrete walls with existing Acrytex paint.

And that’s it! I’m happy you like Boysen Acrytex enough to repaint with it again. Wishing you luck on your repainting project!
