bath sealant - 2 layers?

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.

O O O O O O OOOOO

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, Chris.

It's more the *contents* of the rows... See
