Garage flooring options

If going a plasterboard route it needs to be moisture barrier backed and one or two inch battens to fix to with polystyrene insulation in between battens wouldn't be a bad thing.

I'm probably going to do that in the corner of my garage where I'm going to have the gaming room there.

Agreed but they make a right mess everywhere so you need to mask/paper up. Also you would need to hire a decent paint sprayer gun and compressor to do a decent job. Would have increased prep and cleanup time also the cost of hiring the kit would have been added. Also spraying tends to use more paint as needs more coats most of the time in my limited experience.

The guys that sprayed my dad's factory years ago had decent spray kit, compressors and full body suits with filtered breathing apparatus.

cant see why you say that plasterboard wouldn't last?, although not my preferred method there is absolutely no reason why you can't use dot and dab plasterboard in a dry garage as long as it's cavity wall construction with fitted dpc etc and it doesn't need to be heated, you can still use plasterboard on solid 9 inch walls but by battening first and using vapour barrier membranes and/or vapour check plasterboard, this would be a far more effective method for damp solid brickwork than using sand/cement render which will still be problematic on badly effected damp walls, even if applied correctly, seen many sand/cement renders fail on severe damp walls in my years. You can actually get waterproof plaster which I did get a plasterer to apply to a commercial solid blockwork wall a few years ago, however, it's bloomin expensive and you would definitely need to use a highly experienced plasterer.

Perhaps I have done you an injustice,
In a dry cavity wall garage with a decent roof, dpc etc it will probably be okay. Will you be fitting a skirting board? What is the ceiling detail? Damage to plasterboard is easy. The boards will need a finish either tape and joint or skim coat of plaster followed by paint.
Careful where you put the vapour barrier, there is a calculation which tells you where it is needed, in the wrong place it will trap moisture, the green moisture resistant boards would be a good choice.

no worries matey, this was a question asked by "rivarama" who wanted to query a quote for rendering his garage walls internally, who has now painted the block walls instead, you will be glad to hear I prefer wet plastering over dot and dab

LoL - this convo has turned into a detailed analysis of what is the best construction known to builders when it comes to wall finishing techniques... this forum never ceases to amaze me !!

New house will be getting purpose built garages, part of the design will need to be the overall finish and this thread has provided lots of points to consider, keep them coming

Another coronavirus job - I never really loved the finish of the paint job I did last year; those cement blocks are tough to paint. That’s the reason why I had decided to delay the flooring, until I finally addressed the wall situation.
After staring at the walls imperfections for over a year, I decided to give the spray gun a go... all it took was a big load of paint to be sprayed everywhere, and a quick brush of water on top for the paint to penetrate those crevasses.
I have to say the finish is near perfect and I am please with it.
I am now going to start hooking frames, shelves and banners - and the flooring will go soon after.

Now you need to get a student from a local art school to come in and paint a big Maserati badge on there. (After the lock down ends, obvs.)

Dead easy to do Ewan. Get the flag/symbol onto your laptop and use a projector to project the image onto the wall. Trace out with a marker pen and then paint... easy to follow and I used the same many years ago unsing an overhead projector to decorate the children's ward at my local hospital (not maserati stuff, Disney of course)

I did this in my previous house when the kids were small as well - drew a lot of great children books characters like “le petit prince”, “Peter rabbit, the gruffalo etc... worked a treat.
You can buy one of those iPhone projectors for £50 on amazon - I might just do that if I fail to find a hot italian art student to come and paint my garage first :)
