Hi
Can I run a second bead of sealant over a newly cured first bead ?
(gap was a bit large for a single bead)
will it stick to the first bead of will it lift in time?

thanks

It will lift, I'd do the whole lot again. Sorry!

It'll be fine unless the first one has been contaminated with
something (soap, etc.).

Build it up like a Welder would make a thick bead, five lines, three
lines, two lines and finally one line. Pascal's triangle.

That's not a Pascal's triangle... (I think he'd be insulted that you
suggested such a thing!) ;-)

When I moved into my house in 1990 the sealant behind the sink had peeled
away from the tiles slightly and gone mouldy in th gap. As I was extremely
poor at the time I cleaned it up and just covered over the top with a
thicker bead of kitchen and bathroom sealant. Lasted fine until the kitchen
was redone 9 years later.

A clean fresh layer is fine - the new stuff will stick perfectly. If
it's a bit older you might want to trim a little bit off the get a good
bond.

When I had a big gap to deal with (bath + uneven wall) I (under)filled
the gap roughly, didn't smooth off, and went back the next day to put in
a smoothed, shaped topcoat. There's no way to get them apart now.

A bit of pressure on the second coat (just from smoothing it) will help
it stick.

You're right. It is 5, 4, 3, 2, 1 rods per row. I sit too far from the
monitor,

It's more the *contents* of the rows... See
http://mathworld.wolfram.com/PascalsTriangle.html for further info,
although I don't think it'll help the OP with sealing his bath so
perhaps this is getting a tad OT... ;-)
