Hi, I've had just had my living room skimmed, and have bought some 100mm primed mdf skirting to fit. When the plasterer was here I asked him to try to get as low as possible to the floor, as I was planning to stick the new skirting with GripFill or something... But he didn't go as far down as I'd liked. There's approx. 50mm gap between the bottom of the skim coat and the floor, and the edge is quite rough as well. I'm not sure there is enough flat, smooth plaster to stick to, so I'm considering using plugs and screws, but being dry lined, this adds to my confusion - should I just use plasterboard plugs, or drill a much deeper hole right into the block and use longer screws? Also - as there is a gap behind the bottom half of the skirting, I'm concerned this will cause the screws to pull the bottom in and make the top stick out.. How would I stop this from happening? Any thoughts / advice very welcome! Thanks.
