Hello, so around 6 months ago I re-tiled our kitchen. The tiles go down to just above the existing worktop as they had done before, so there was a gap to fill which varies from about 2mm to 4mm at the most. I looked online for ideas and decided on using standard white kitchen sealant to do the job. It looked great at first and for a while, but has now started to "pull apart". This is along most of the length now, apart from a couple of areas which are still OK. I'm going to remove it all soon as it looks very unsightly but I don't know what to replace it with. Should I try sealant again but using a much larger bead, or something else like small plastic trim? I'm not really sure why this has happened as I don't think the worktop has moved (and certainly not the tiles
) Any ideas welcomed. Thank you
