HG 506100106 Impregnating Protector Against Penetration of Grease & Dirt-Pre-Treatment for Natural Stone, White, 1L

This is a clear liquid. The instructions suggest rolling it on - two coats. We have recently had a Bath Stone hearth installed. Bath Stone is a very porous and fragile sandstone and we wanted to protect the hearth from stains. This product was easy to apply and we left it a few days to dry in. Once dry the impact on the colour of the stone is minimal - it does not darken it at all. There is no odour. We have only had one spillage - of water - since and it beaded on the surface for easy mopping up. Overall, I can highly recommend this product for protecting porous stone.

è facile da applicare sia su pietra che su rivestimenti a parete, con normali pennelli. L'appicazione va ripetuta più volte una volta essiccata la presedente. Il risultato è ottimo anche a distanza di tempo.

Ok

Looks to have done the job on an outside marble table which had got filthy over the years. Only time will tell how well it is now protected.

I applied the product to my recently installed limestone hearth. It was easy to apply and didn’t change the appearance of the stone. I always find HG products to be safe and reliable for cleaning and protecting natural stone.
