Tried using a heat gun to remove old tile adhesive and it went sideways

I was stripping the floor in my kitchen and thought the heat would soften the mastic faster than scraping. It just made a sticky, smelly mess that took twice as long to clean up. Anyone have a better method for that stubborn black adhesive from the 80s?

Skip the heat gun, it just cooks that old tar into a nightmare. Get a floor scraper with a long handle and a pack of sharp blades, the kind you hit with a hammer. Spray the mastic with a product called "adhesive remover," let it sit for like 20 minutes until it turns dark and bubbles, then go at it. The chunks will come up way cleaner. You'll still be sore tomorrow, but you won't have that gummy tar soup everywhere.

Ever try a wallpaper steamer on that mastic after the remover softens it?

Yeah I was a total heat gun believer too, thought it was the magic fix. That black gunk from my bathroom reno last year proved me wrong, it just turns into this awful tar-paste hybrid. I switched to a chemical stripper like Goof Off, let it soak in good, and it scraped up in these perfect rubbery sheets. Complete game changer.
