I need to plaster up a section of wall approx 6 foot high by 6 inch wide. The previous occupiers had a cupboard standing in front of it. !! The wall is a 'dot & dab construction'. This section was obviously knocked out to put in a 10mm2 cable for a shower. What is the best type of (DIY) plaster to use and can I just 'clag it on' over the T&E cable? I am not too bothered about having a perfect finish as the wall is going to be wallpapered after.
TIA
John
