My kitchen has black sealant between the dark tiles and the horizontal worksurfaces and metal sink. The sealant is three years old and has fallen out around the sink (in spite of being wiped dry each time the sink had been used), and has parted from the worksurface all the way along. Four years ago the same fitter installed a bathroom, and the white sealant used is still 100%. I need to replace the kitchen black sealant. I've no idea what product was used. Do black sealants contain particles of black, and is this why the sealant has failed? Do all black sealants have this problem? Are some (uk) black sealants better than others? What would you recommend?
Use Stixall, it's available in black,it's hybrid polymer based sealant,a superb sealant,can't praise it highly enough, sadly it's only available from our host competitors,& they stock the black. See video in this linky. http://www.everbuild.co.uk/stixall/stixall-1
