I was just doing some work at home and needed to attach some conduit to block wall. Got the screws and drill bit at the local big box hardware store. They were Tapcon brand, but I assume other would work.

Subject: [CRTech] Attaching foam to our walls
www.atsacoustics.com about how to install their panels but they only suggested using plywood behind them. Our studio walls are painted cinder block walls and have tried MANY things, even like liquid nails.
Nothing holds them for more than a day or two. They are 15” x 36” so there is some weight to hold to the wall.
Any tube or paste or ideas you have tried would be GREAT to help us.
