I've had some plaster coving put up in my lounge by a builder who used Coving Adhesive. Is it normal when putting up coving that on one length of the wall that 2-4 pieces might be used as I think they were offcuts from my bedroom. As the problem I have is that where there is a join you can see all the adhesive on top which I've put down as shoddy!! – can this be sanded down as I tried a little (possibly with the wrong sanding paper) and some paper came off!! I just thought that a long piece of coving would have been used and if any joins they might be nearer to the corners. I probably wouldn’t have had a problem with 2-4 pieces being used but as its so obvious now I know that once I paint it it will highlight this even further. I'm getting the builder to come back but just want to know if this is salvageable and get him to sand back the bits that are bad or if I should just ask him to take it down the only joins might be in the corners – my room is 12ft 8 by 11ft 5. I hope someone out there can help me cos I was happy with all of the other work he did for me - but obviously coving definitely isn’t his thing!
