In my kitchen the wall resembles the Himalaya Range of mountains.
I would like to stick some plaster board onto the wall to cover it all up and then put some tiles on. Length approx 19' (foot) x 18" high (inches).
The only bags of plaster that I can purchase from the local builders supplies is quite large and most of it would be wasted. No DIY shops for 8 miles.
I was thinking of stick plasterboard to wall with something that I can put in my sealant gun. I know this would probably cost more than plaster but at least none would be wasted.
Your suggestions as to what to use would be most welcomed.
