I want to install porcelain tile on my concrete patio.
I removed the indoor outdoor carpet with no problem.
Is there any way to remove the yellow/brown color glue.
Tried a 4" grinder but it just makes the glue soft and makes a mess
On the grinding wheel.
Tried a scraper with no luck.
Should I use a glue remover solvent,and if I do will the thin set
Still bond to the cement.
