hi there, we have interior feature brick in our house and it is dark and dated looking. I've noticed bunnings sells gyprock sheeting and cornices quite cheap, so my question is..is this job as easy as it sounds? can i just use some kind of glue (liquid nails?) and screw these panels onto the existing brickwork? will the gaps between the bricks (morar) be a problem for any reason? any tips would be appreciated:)
