PerfectPrimer Encapsulant - Seals Unwanted Mastic & Prime for New Application - Matte Grey, 1 Gallon

The PerfectPrimer covered the removed tiles better than we expected based on others reviews. Make sure to use the ‘Gatorade’ type rinse included in the packaging to treat the black mastic areas. The primer also covered over well with using cement paint. I bought 3 gallons if the Primer due to concerns of poor coverage but only needed 2 gallons and was able to return the unused / unopened remaining gallon. Our project was about 300 to 330 sq feet. Would recommend using the PerfectPrimer to other DIY ers. Good luck on your project.

Was unsure about ordering online but transaction went very well. Packaged carefully and it was worth the 3 extra days because this product is perfect for priming over old adhesive that contained asbestos. Came with a cleanser to prep surface. Application went very well

PerfectPrimer completely encapsulated the old asbestos tiles on my basement steps. It was easy to apply and it did a great job. Yes, it is expensive but it's a lot cheaper (and safer) than hiring someone to remove the asbestos tile.

I ordered this for a friend to be used in a basement over an old floor before the floor was painted. I saw the finished project and the floor looked amazing.

Covers well but expensive

Delivery was fast and accurate 🙏🏼

Was kind of skeptical at first but after applying primer then the floor im very happy with the res

Excellent in all respects

Just applied so no rating on long term effects-does it do what it says it will-time will tell. Very pricey. This is not a WalMart product, so rating is not related to Walmart!

If you touch it, even after a couple days, it comes up. It seems to need to be built upon immediately - possibly while its wet?
