Sealant around bath against travertine

[AliGage]

Well that answered my question

Just thought I'd say I used the Ottoseal S70. It was great to use! Went on really smoothly. I think I need a bit more practice before I manage to do a perfect job though.

In the past I have found it hard to get the Silicon to take to travitine! I find forever white works quite well.

You didn't read the previous comments then....?

Ben is new!
If I had to read through all of the comments on some threads I'd have retired 6 years ago!

Should I have?

I have always used Mapei Silicon for travertine & never had an issue,
When I fit travertine it gets either 2 or 3 coats of sealer so I don't see how the Silicon can then stain the stone?

I contacted Otto Chemie who were really helpful and sent me this little pack from Germany. I'm very impressed with the metallic ones!

It's because sealers don't seal against acid.

Ah ok, I use Mapeisil & it's solvent free..

OK, thread resurrection time!

Otto seal, looking at either S130 or S70. After reading the data sheets it would appear that both need primers for sealing against uPVC and/or acrylics. I have both, (window and bath), along with counter tops and bath panel which are vinyl wrap. Walls and floor are trav.

So the question is to those of you using Otto is do you use any primers? If not have you had any known issues?

Ta!

Use primers.

How did you get hold of them? Do you have their contact details?

Sorry to raise this again.

I've been in contact by phone to the UK distributor of Otto. Very confused now!

First person I spoke to recommended S100, very nearly placed an order and then realised that this product is NOT suitable for stone! I rang back and was told that I need S70 but I don't really need to use primers. I then re-read the data sheets.

Now I have four different materials to seal to; travertine, an acrylic bath, a vinyl wrapped bath panel and a uPVC window. having read the data sheets it is recommended to use a primer for PVC unplasticized. Primer 1217/1227. The distributor only has 1217 and it's nearly £18 for 250ml. They also didn't tell me I should use it.

Has anyone that has actuay used this stuff used the primer? Are there any aternatives to Otto for the purposes I need to use it?

Any help and/or advise appreciated!
