Hi Tex,
We bought a house recently that is approx. 20 years old. Most of the interior floors are slate. In some places the sealant has completely worn off in other areas the sealant is ok but I can't get it really clean and in other areas there are salts leaching up. How do I get all of it clean and ready to reseal and what sealant would you recommend? Toxicity levels are a concern to me with 2 small children.
Thanks

Hi Nicole,
if wishing to use a water based topical sealer like:
http://cswcoatings.com.au/topical-natural-stone-sealer/
, you may apply over existing sealer providing it is of a sound nature..eg: no peeling or flaking bits. This will present a semi-gloss finish opposed to our penetrating line which is pretty much invisible. You'll be pleased to know also that our water based lines are all low VOC meaning no intoxicating smells!
In order to remove the salt deposits there really is only one compound that is effective, please use a phosphoric acid like:

Unfortunately in some areas there are flaky bits. What do I do there?

existing sealer will need to be stripped. Please use:

once stripped, either a topical or penetrating sealer may then be used!
Hope this helps.

Have laid a slate tiled patio some months ago and some of the tiles are delaminating a little following very hard and frosty winter. I believe it needs sealing please advise which of your many products you recommend for best effect, longevity and DIY application it is an area 6 x 7 metres

Hi John,
best place to start is our Slate sealer section here:
https://cswcoatings.com.au/product-category/slate-sealer/
as we supply quite a few different products.
First step is to determine if wishing for a Film Forming or Penetrating sealer. You can read about the differences here:
https://cswcoatings.com.au/film-vs-penetrating/
Please note: A product like our Protect & Enhance (film forming) is a popular choice and may help slow down further deterioration though will not help with existing delamination/deterioration.
Any further questions please do not hesitate to ask.
