Review on Ampulla Water-Resistant Garage Wall Protector - German Design (1/4" Thick, White) by Jake Meyer

Used on a concrete wall in my garage. Adhered firmly to the concrete with no issues and even without major cleaning (I blew the dust off with an air compressor first, but nothing else). This stuff is great as advertised but it's only 1/4 inch thick and while it's very hard and dense I just can't trust it as much as I would like. If it was 3/8" thick or 1/2" thick I would definitely trust him 100%. If I was using this on wood or drywall it would probably be fine, but on a solid concrete wall I'd prefer a little more padding. edges and I am very happy with the end result.
