I'm resurfacing a fireplace wall with MSI Ledger Stone Panels (6 in. x 24 in. x ½ to ¾ in.), but I didn't want to deal with the mess and hassle of mixing and troweling Thinset, - nor did I want to sacrifice performance over
convenience. I mean, who wants panels or tiles falling off the wall. This stuff is about twice the cost of other products I've used in other renovations, but stuff works extremely well. There are other products that are more expensive than this, too, but I'm not trying to glue a 50-pound anvil to the wall either.
Bottomline: More expensive. Quick grab, yet allows several minutes to fine tune/level tile or panel. Super hold. I had a panel upside-down and had to peel off… did I mention sick Grab”? So far so good .. only time will tell for sure.
