Hi,
Was wondering if someone could advise on which or what type of mastic I should be using around windows and window board internally. So far I have tried Dow Corning 781 Acetoxy Silicone Sealant http://www.screwfix.com/p/dow-corning-781-acetoxy-silicone-sealant-white-310ml/45959 which gave a good finish but seemed to leave a clear line on the painted plaster where I have cleaned it off and Geocel Painters Mate Flexible Acrylic Filler http://www.screwfix.com/p/geocel-painters-mate-flexible-acrylic-filler-white-310ml/35403 which left no marks but has cracked up in places.
Any advice would be really helpful?
Thanks.
