Shower Tray Sealant

[Shutpa]

Am now ready to start applying the Dow Corning recommended earlier but, (as usual), I have a problem. According to the tube, the silicone offers excellent adhesion to porcelain, glass, ceramics and painted surfaces but makes no mention of aluminium! I had intended to apply it around the aluminium strips beneath the doors and at the side. Will it do the job and seal the aluminium/ porcelain join?

If the aluminium is anodised (which it probably is) and the coating is in good condition, I don't see why it wouldn't stick and seal long term. Naked aluminium oxidises with a poorly adherent oxide layer which might be more problematic and might require an etching primer before application. I would phone the technical dept at Dow Corning and hopefully they can give you definitive advice.

It will stick as long as you clean surfaces with white spirit.

Contacted DC's customer support on line and they gave the go-ahead. Still, I like the idea of a final clean with white spirit and will take your advice. Thanks again.
