Hello. I was in B&Q and asked about a sealant that I can use behind kitchen counters and the stove. The lad working there gave me soudal roof and gutter sealant. I asked him a few times if it was a suitable kitchen, he has confirmed with confidence. I have applied it and started reading online and worried about its safety. What do you think? Should I remove it or is it fine to leave it?
