Sealant around bath against travertine - TilersForums.com

[JulesA]

Hi

I've looked and looked and I couldn't find an answer. But I'm happy to just be referred to an existing thread if I've missed it.

I need to replace the sealant around the bath. But the fact it's against travertine seems to make it tricky. I thought I could just buy any sealant until I noticed on the tube I'd picked up it said not to use with natural stone. Topps Tiles said not to worry, to just use anything, but when I called their helpline they said to make sure I used a neutral-curing one.

I've found a few posts where people recommend neutral-curing sealant, but apparently there are some neutral-curing ones you can't use. According to the technical specs anyway. I found Soudal Silirub+, but the S8000 that you can buy in Screwfix says not to use it on natural stone. It specifies Silirub+ S8800 for that, but I can't find where to buy it! And someone recommended Mapei Mapesil, but in their technical spec it says it's suitable for natural stone but that it might stain porous stone; so can you or can't you! And where do you buy it?!

I just want to replace the sealant without messing up the tiles!!

Hope someone who has had experience with using them can help.

Thanks

Jules

Stonetools.com sell Ottoseal S70 for natural stone.
I use it and it's very good.

I use Mapesil on all jobs including stone without any staining issues

Ottoseal S70 also from Broken Link Removed. Excellent stuff.

Likewise....never had any issue

Mapei do a neutral cure silicone specifically for stone.

Thanks everyone

Can I check that someone recommending Mapesil meant Mapesil LM: Broken Link Removed Seems to be the stone one. Although the spec doesn't mention using around baths. I like it when the spec confirms what I want to do with it!

Or the Ottoseal S70 sounds good.

Looks like whichever one I go with I'll have to order it online though. Unless anyone knows of a London shop where I can buy them? None of the chain trade places, never mind DIY, seem to sell any to use with stone.

Thanks

Don't use MapeiSil - even LM (low modulus)
Use the proper gear for a proper job.
MapeiSil is ok but not for stone.

I was led to believe LM was made specifically for stone.
How do the two compare on cost?

Ottoseal S70 is cheaper and far better.
The risk with these "in-between" types like Mapeisil is a risk of silicones in solution staining the stone.
With specific sealants like Otto there is no risk.
It's also very thick and REALLY easy to apply.
Seriously - try it!

This leads us to believe it can fix tiles to wood too!
