Hotspot Slate Oil Sealer is easy to use. Do make sure your area is well washed, free of dirt and totally dry before applying the Slate Oil. Rub it on well with a lint free cloth. We use it on our hearth, which is smooth sandstone (from an old pigsty roof). Easier if you do small areas at a time, then sweep your cloth over the whole. Allow to dry (2 hours for us on a warm day). Give a second coat as before. Leaves a lovely soft sheen, which can be washed. We have a multi-fuel stove which is left on 24 hours during the colder months. Hearth is washed every morning and retains its colour and sheen. We reapply the Slate Oil once each year to continue protection and keep it looking good, and have done this now for a number of years. Highly recommend this product and will continue to purchase and use.Read full review

I used the old oil product on my slate hearth in the past, I now believe this is no longer in production. I bought this replacement which can only be described as a milky white gloo which retains this milky appearance once set. Really awful so much so I spent 3 days with wire wool and white spirit trying to dislodge it from my fireplace. I would not recommend this product to anyone, Hotspot please bring back the old slte oil product which was really good.

Tried this based on the various internet reviews. It's easy to use, does an excellent job, and the small bottle was easily big enough to allow me to use 3 coats on my new slate hearth. Definitely recommended.

Used it to seal my newly cut fireplace slate, only used 1 coat rubbing it in and it came up a beautiful deep black, couldn't be happier.

Don't use it does not work . Called the manufacturer and this has been superseded by a clear liquid. Had to remove the the white version with white spirt.
