Hi Michael. I am assuming you are having laminate worktops fitted and hence your concern, (granite, quartz, corrian etc would not pose a problem). There are two things to bear in mind with laminate, it is bolted together so you will need to leave room for the bolts - around 100mm. Secondly, even with the joint fully sealed with Colourfill there is still a good possibility that it will 'blow' over time if it is constantly wet. Hope this helps, Karl
