First post; Building or General forum? I've decided the former, but please be gentle if wrong; I did think before I posted.
I have just moved in to a conventionally built modern house with stud walls. One of the fitted shelves is tearing the "heavy duty" plasterboard type Rawlplugs(tm) out of the plasterboard because the holes were drilled about 1mm too big (11mm when 9 or 10mm is actually needed). In fact it's a wonder that the screws were ever nipped up in the first place as I reckon the plugs have turned round and round.
The shelf is 10" deep and 2' wide and fixed by two T brackets where the long arm of the T bears the shelf and the short arm (about 4" long) mounted vertically on the wall has two screw holes. Maximum load will be about 10Kg including the weight of the shelf itself.
I want to keep the shelf in exactly the same location, so need to fill the holes and redrill them; I don't want to use spring loaded expanding toggle bolts so the question is, "fill them with what?"
Do expanding foam gap fillers permit drilling followed by load bearing such as with a snug fitting Rawlplug? If so, what type of Rawlplug? Plasterboard or "conventional brick type"? The bottles mention sanding, but not drilling, hence the question. One thing that I am aware of is that if I use such a product I need to leave room for further expansion as the foam cures as well as a water mist per the instructions.
Many thanks.
