New Garage Interior Finish
Permalink  

Hi guys,

I am starting the construction of my new garage next week and I am wondering what kind of material I should use to finish the interior walls.

My options are either gyproc, aspenite or plywood.

I think plywood would be more solid if ever I want to install cabinets or various support and racks on the walls and would also absorb moisture in the garage.

I would imagine that he would be a clean finish once painted.

What do you guys think? Any ideas or recommendations?

Thanks

Steve, I'm in the same boat, built mine 4 yrs. ago, 24 X 36 have it insulated & vapour barrier up & heated. I was going to do it in plywood [ easy to hang tools etc. ] & cheaper than drywall & no taping, but then someone said insurance co. might not insure it anymore due to fire hazzard!!! SSSOO, now I'm back to drywall,going to see about an estimate soon, as the ceiling is too high & I'm not as young as I think I am!!!!!!!!!! Pete

ask your insurance company about fire rated paint being used over aspenite or plywood.

Plywood or chipboard for backing covered w/ drywall or siding mounted vertically..

If drywall use the bathroom/basement moisture resistant stuff!.

The vertical siding is great if you're washing cars inside also nice for easy periodic cleaning w/ a pressure washer!.

If you use real plywood you will never regret it. Either painted or if you tin it, you will have the most solid backing . I regret using that crap OSB chipboard anywhere I have in the past....

Check the building code. Unless your shop is attached to your house it doesn't reguire the same fire rating as a residential occupancy. In a commercial building they drywall and then sheet with wood. The wood shouldn't affect your insurance. That is bulls**t.

I also hate OSB or MDF ... they act like a sponge. If you use drywall, use blue or green board on the bottom row. Make sure you seal all gaps/holes if it's attached to your house (carbon monoxide/smoke/fumes).

Speaking of smoke/fumes, does anyone have a tailpipe hose to go outside of their workspace? What kind? Where did you get it?

Yah, hate OSB with a passion. Really concerns me when I drive by a new subdivision and see OSB being installed on the roof.

Bought a tailpipe hose set about 25 years ago. It works for both single and dual exhaust. Came with the hoses and a flapper for thru the garage door. Brought the hoses with me when we moved but didn't have the heart to take the flapper

drywall over plywood is a very expensive finish... you might want to look at hardi-panel or something similar if you want a water resistant and durable panel... plywood on its own its quite good as well, better than osb....

I used drywall in my shop. Nice and bright and easy to finish. My foundation comes up about 8" so the drywall is not to the floor.
 If I am installing something on the walls I put some type of backing behind it and screw it to the wall studs.

 A couple questions
Are you building the walls on 16" centers?
Are you going to heat the shop all the time or only when you are in it? Are you going to be washing your car or spraying water in the garage?

Thanks guys,

SD396,

Yes I'm building the walls on 16" centers and it's going to be heated all the time.

I don't plan on washing the car in the garage

Similar to Brad, my garage is 1/2" gwb... i put blocking where i think i might need it, but at 16" o/c there's more than enough opportunity to screw to... but being an unheated garage some tape joints let loose a bit...

Here are a few reasons why I used drywall in my shop:
To avoid paint peeling off wood. I wanted my shop all white inside for brightness.
Cost. cheaper than steel and easier to clean.
Seals up tighter, less drafts
Looks clean.

I will be sheeting the inside of my new garage next week and have had more than one discussion regarding the material of choice. However, insurance is a significant factor and followed closely by expense. Plywood is very expensive compared to gyprock so in that respect there is no comparison. Therefore, I am going with gyprock and will paint the bottom row with a water resistant product...although I don't plan on washing my cars inside. I have 8" of concrete between the floor and the gyprock.

Regarding fume extraction, check out a product called 'Whole Home Fans'. A friend has one in his garage/house and it changes the air in no time. Due to the size of my garage I am going with the AirScape 4.5 unit rated at 4673/3100 CFM.

One more thing to consider...when you have any 'pieces' or end cuts laying around take the time to nail/screw them between the studs where you think you will be hanging stuff. I have been doing this in the evenings when the framers are gone. It's a great way to reduce the garbage pile and a trip or two to the dump. Good luck with your project.

If you are going drywall you should use the waterproof, bathroom style board. It is only a couple of dollars a sheet more but it will be worth it. If it was my shop I would use 1/2 plywood and just paint it white. No taping. In the future when the shop requires paint again and you want and can afford it you can drywall and tape it then and make it pretty again.

I personally have not carried insurance on my shops for over 25 years. The cost was ridiculous. I live in the country and there are no fire hydrants, the insurance co. would not cover me for explosion, electricial, or water damage. In 1985 the cost was just under $2000 a year. So over 25 years I saved $50,000. I did have insurance on the house and my attached 24x24 house garage. In order to satisy the bank for mortgage reasons I had the house insurance raised to cover the balance of the mortgage and the bank was the first payee.

Hey guys have you ever considered using painted steel roof type sheeting?  I just put 1x4's over the vapour barrier and screwed in the low ridge sheets vertically.  Fire protection, brightness,  painting,  and general ease of cleaning are taken care of in one step

here is a shot of my shop last year when we were working on  some sets for a play just to give you an idea of what it looks like.  i used galvanized on the ceiling because i had some laying around, although I would have preferred white.

You can also get the sheets cut to any length you speciify (at least I could) so it saves even more hassle.

I used 1\2 inch plywood on my shop. Sealed and painted it white. It's bright and solid wiht usable walls and it's been on there for 11 years now. It does not show any signs of needing repainting yet. I used one coat of sealer and two finish coats of paint.
I would do it the same all over again as I am thrilled with the results. I have infloor heating so everything stays dry all the time. Maybe that helps with the paint staying good for so many years.

As you can see, I don't have a lot of wall space left but here are some overview shots and some closeups. Let me know if you want more pic's.

Thanks Lotsatas for the pictures. Nice signs collection you got there :)

I'm still undecided, but I still have time to think about it.

Thanks guys.
