Ok, doesn't mean it is bad though.. but Stonefix adhesive was like that ..
If i dropped , say Weber spf rapid white and left it for a few hrs , then it would require a scraper to get it up.. but this depends on the adhesives set time and some are 3 hrs to grout but can be longer to fully harden and this will male cleaning off tiled floors easy .
ah, fair enough. I tend to use Webber mostly, so it's probably just because i'm coming from that.
