Looking for some economically viable ways to tart my garage.

It is a large space of circa 100m2 (6 car) and underneath the house. When I bought the house, the walls had some evidence of damp and flaking. I got a quote from someone to treat the walls but given the size of the space it was prohibitively expensive and remains unjustifiable - if I were to ever sell, a buyer would probably not be as interested in the garage as I am as a petrolhead.

To make it look better and as a lockdown project I sprayed the lower section of the walls (the upper section being free of any evidence of flaking) with black paint. Since doing so, the flaking has almost stopped completely, almost as though the wall has been sealed.

The walls look good from 5 yards away but up close still show the unsmooth texture of previous damage.

I wondered whether I could somehow cover them at a proportionate cost - was thinking perhaps a thin plywood or Perspex sheeting all round up to about 2 metres in height. If I were to bond or just screw black plastic sections around to that height it would improve the look and make it smooth.

Seeking some advice as to flaws in my logic...which I have no doubt there are!

I'd suspect the flaking is moisture related, so anything you put on needs to be quite 'breathable'?

ZINSSER Peel Stop might be a good bet

What is interesting is that since painting the walls (nearly 5 years ago now!) there has been very little evidence of ongoing flaking.
