Cheers I do it straight away; the tape takes away the excess leaving behind a nice neat edge. If left to cure the silicone is likely to remain 'as one' thus negating the purpose of you using the tape for a straight edge. Indeed if the silicone hasn't firmly attached itself to the tape then it'll likely leave a flappy edge at best. Mathew |

Sorry, this should have been part of the FAQ text (the one that begins with soaking your finger in 50% washing-up liquid). Smooth the silicone right down to the edge of the masking tape. Where the edge of the silicone bead meets the edge of the tape, the silicone should be no thicker than the tape itself. Then peel off the tape immediately, pulling it away from the silicone. That leaves a nice feather edge on the bead. If there is any sign of lifting, just run your finger VERY LIGHTLY along the edge of the bead to put it back. -- Ian White Abingdon, England |

Good luck! Simon. |

The tongue works well too, much better than a finger. (I tried it on food-safe silicone). Getting into tight corners may be a problem, though may be valuable practice. |

Just to be clear: remove the tape soon, but pull it off slowly and gently. The tongue works well too, much better than a finger. (I tried it on food-safe silicone).

Can anyone help me with the width issue???????????!!!!!!!! In my opinion (and no doubt others will disagree) you need about 3mm of sealant on the bath and about 3mm on the tiles for good adhesion. Maybe a bit less.

I'm sure we'd all like to see it. -- Tim Mitchell |

It's very much easier than you seem to think, or fear. You've seen hundreds of silicone beads, both good and bad. Make yours about the same width as the good ones - it really is about that simple. If it looks right, and feels right when smoothed down using the body part of your choice, then it probably *is* right. -- Ian White Abingdon, England |
