Q:Cross stud is in the wrong place so can't fix to that. The cabinet is large and the ceiling is sloping (attic) so I'm restricted in where it can go. I can see a cross stud but it's not wide enough - when I marked the screw holes the screwdriver went straight through and didn't touch anything. Will toggle bolt type fixings be adequate don't want it too fall off wall with everything in it and break the basin and tiles!!

Spider anchors. Which are a slitted metal tube with a nut fastened into on end of it. You read the picture instructions and follow that. Ask hardware store. There are also large twisy plastic ones which work as well by a different principle. Your choice. Ask the staff there OR Cut out the plaster board and put cross board in lower and reaffix the plasterboard OR Put on a plywood sheet on the wall first and screw that sheet to the cross boards and verticals. Use 3/4 -1 plywood. Then finish it off with a corner moulding all around the cabinet. Each way works. It depends on the amount of work you want to do

Q:I am making a model that requires me to shape, paint, and glue something that will represent small stone slabs (1/2 thick). I do not have access to power tools. I need to cut out unique shapes and then sand them down considerably to make a dome. I was thinking about plaster board but the material I need does not need to be that sturdy. I basically need something between plasterboard and styrofoam (if that makes sense). Any ideas would be appreciated.

I have no idea why you would make a dome like one would make an iglu? When you could use plaster of paris in the same why you'd do paper mache or putting an arm in a cast. Blow up a ballon to just under the size of the dome you need then apply the plaster thicker when you get close the size you want so to be able to cut it to size and sand it smooth.

Q:We need to put new wallpaper up in the bathroom but the wall is not plasterboard its chipboard. Do you use a special paste/glue as won't wallpaper paste (or paint as an alternative) soak into it? Also would we need to use a lining paper too as that is what we have taken off with the paper that was up.Thanks for your help.

1. Prep the wall by sealing it. Mix PVA with water about 50/50, and paint this on and let it dry, then do it again with a second coat. This will stop the natural absorbency of the chipboard from soaking the water out of the wallpaper adhesive (causing it to fail to set correctly). That way, later coats of wallpaper will stick. 2. Final prep: wash the dry, PVA-sealed surface with a coat of wallpaper adhesive that has been mixed too thin, so that after it dries there is a very thin coating of adhesive on the surface of the wall. 3. Apply lining paper horizontally onto the prepped dry wall in the normal way with wallpaper adhesive mixed as per the packet instructions. Allow to dry totally. 4. Wallpaper in the normal way. This is exactly the same procedure if the chipboard is not raw but has a veneer skin. You still need the PVA coat - on veneered board it isn't to compensate for the absorbency of the chipboard, but to compensate for the fact that wallpaper paste won't stick to naked veneered chipboard NB choose your wallpaper carefully - many are not suitable for the steamy atmosphere in a bathroom and will peel off after a few weeks
