Carborundum Stone

Arrived in good time, well packaged and a good quality product.

Good product

I used this to flatten and smooth off a sand and cement floor screed which had a float finish. This stone worked really well, I wetted the surface and worked progressively across the floor using a circular rubbing motion, it took out all the float marks and there is very little wear from the stone.

Very poor compared to others that I have used.

This works quite well at smoothing down concrete screed, it requires a good amount of effort but it works better than most of these I've tried and it lasts a long time. The price is a bit high but probably works out better value than buying two in the long run

Yes that's the one.

Concrete floors

Used this to rub down any high points in the floor screed prior to tiling the floor
