“I found this product very good and will continue using it. The only qualm I had was -I made a bit of a hash of it trying to keep within the ruts of the tiles.I'd read the instructions but didn't have much success
.I'm sure if there had been a nozzle which could have been screwed on to the top, I would have made a much better job of it. Never mind,as I continue with my quest hopefully,I will get betterat it ( It's old hands trying to do a neat job)”
