Seals and stains on Caithness Stone / Scottish Slate - TilersForums.com

[stanbalder]

Hey Folks,

I am putting down some Caithness stone in a kitchen area. The stone is laid and now needs sealed. I have some Lithofin MN StainStop left over from a previous job and have applied this. I spoke to Lithofin themselves and they recommended I use this.

I have prepared a sample tile with the MN StainStop. The problem is, it stains. I spilt some oil on the sample, and its pretty obvious, and doesn't clean off. Can anyone help? Are there other sealants that would work / are better for kitchens or am I simply using the wrong cleaning products to shift the stain.

Regards

Stan

Hi Stan.. How long did you leave the sealer once applied before doing this test.? and how many coats..?

Hi Dave,

Thanks for your reply, it was one coat only, and I left it 24 hours before putting oil on it.

Having noted on the tech sheet they say 5 days keeping the stains off, perhaps I have been hasty in my testing?

Regards,

Stan

I think so and you need to add sealer till the stone will not take anymore.. then yes leave to cure..
