It's been 5 years since our firewall was painted with elastomeric paint. It's starting to peel on some parts so I want to repaint it again.
Do I have to remove the old elastomeric paint before applying the new one? Ofcourse the peeled parts are easy to scrape off. But what about the parts that are still bonded well, which is the majority of the wall? The peeling parts are only about 5% of the total area.

I usually scrape first using a scraping tool, after which I follow-up with a cup brush on an angle grinder. If no more paint is giving way then that is only the time I prime then proceed with the finishing coats. HTH!

Re: Old peeling elastomeric paint
Agree with opzuk. Scrape all areas and clean with mild soap and water solution the prime with a concrete primer and sealer preferably Prime_R which is made to penetrate, seal and protect your concrete surfaces. It also reconditions your existing paint and forms a protective film for next application of elastomeric paint preferably Flexseal elastomeric paint.

Re: Old peeling elastomeric paint
Yes, use Prime_R which is made to penetrate, seal and protect your concrete surfaces. It is better than the more common concrete neutralizer. It also reconditions your existing paint and forms a protective film for next application of elastomeric paint preferably Flexseal elastomeric paint.
You can PM me should you need prices for them. 🙂 We supply retail/wholesale and do deliveries too. 🙂
