Thank you for your comment. The Tenon Concrete & Mortar Dissolver RM is a less aggressive concrete remover to get unwanted dried concrete off of tools, ready mix trucks, etc. This is another step people can take to make sure their equipment is clean and free of dried concrete.

If you mixed it properly and used the right product, they just don't! Some thinsets got this property also, but in my experience they are way more expensive e.g. 2x, 3x the price of the stone veneer.
