Dry wall or thinset?

[pcoffroad]

Hi all, new to the forum (though I have been luking for awhile). I'm having a new shop being built beside and back somewhat from my old shop with a breeze way to connect the two. New shop will be 36' by 50' with a 16' carport. Interior height is 15'. I'm trying to save were I can but want my garage to look good inside. I'm not sure if I should blueboard with thinset or just drywall? My plans for the garage is to do some auto detailing (meaning washing inside in the winter time), and general repairs to my own vehicles. I spoke with one guy and he told me the problem with thinset especially on the walls is it will crack if I start hammering benches on the walls, etc. I'm not against drywall as my old garage is dry walled, painted and looks good and I can save about $1800 over thinset. The ceiling in the new shop is inclined with about a 16' flat section in the middle. Any ideas or opinions would be great. Tks ,
Paul

First of all, a correction on your terminology. Thinset is a portland cement based adhesive mortar used for setting tile and stone. The finish you are referring to for blueboard is a skim coat of veneer plaster. Veneer plaster is somewhat of a regional thing and it seems to be losing ground to drywall. There's nothing wrong with drywall or veneer plaster. I'm in Massachusetts and we still use blueboard and veneer plaster. I use it on all my jobs because once the joints are taped and the plaster is applied, I can start hanging trim (often the same day) and there's no dust from the sanding that goes along with a drywall job and the total time from when the board is hung, to when I can get to the next phase of the job is considerably less. Also you have been given bad info about the veneer plaster cracking if you attach benches to it. Veneer plaster is rugged and you should not have any issues with impacts or fasteners doing any more damage than they will with drywall. One thing I like to do with veneer plaster is let the plasterer do a "skip trowel" light texture on the ceilings and sometimes even the walls in garages. The veneer plaster is a pure white product and the ceilings won't require any paint at all. The ceilings in my garage are done this way and have had no paint in the 13 years they have been there and they're still white. So, balance project time, dust and not having to paint the ceilings against that 1800.00 difference.

I have a distrust for any kind of drywall in a working space.
It breaks under impact and ***** up water if splashed.

In your wet area go with plastic panels of some kinds.
There are a number to pick from.

In the other areas go with wood of some kind.
I prefer ply wood but lots of guys are happy with OSB.

Paint it white right away, before you start putting stuff up against it.

Would like to thank both of you for your replies. I'll give blueboard some more consideration. Not having to paint the ceiling is a plus. I also will look into putting up some vinyl on maybe the first 5 feet up the wall for water. The building has a 6" knee wall.

6"? Sounds like a shin wall.

That would be the top part of the stem wall, not a knee wall.

By 6" knee wall I mean that the 2x6 stud wall is sitting on 6" of concrete which was poured at the same time as the floor.
