Yep—I know it says to use it on floors but I’ve seen people use it on walls too. Also make sure whatever brush or roller you use is a material that it won’t melt (like cotton).

Even just a nylon paintbrush or rubber roller should work but ofc read the instructions

IMPORTANT EDIT: do NOT use an angle grinder and steel brush is you use this stuff lol. You will have to scrape it by hand after but it comes off like butter peel
