I saw a great video on You Tube about applying sealants with the use of a special masking tape which looked liked Sellotape.
He taped a line of it above the sealant area - then a line of it below leaving a space for the sealant to be easily applied.
I found some sealant tape at Homebase but it wasn't the single tape - you had to apply both top and bottom at the same time and it was really difficult to get straight. I ended up cutting it down the middle but this was very fiddly.
Does anyone know where you can buy SINGLE rolls of this tape as in the YouTube video?

you dont need tape,anyone can do a good silicone job,go back to youtube
and enter,how to silicone a shower in a static caravan.

'Anybody' does not include me - I have tried it before and got into a right mess - but I will watch the video and see if I can improve - I did find it easy using the tape though.
