I have a customer with some pretty severe reflective staining from spot bedding on his Indian Sandstone patio.
It was laid 2 years ago and has never been sealed.
Does anyone know of any way of reducing the staining effect?
I understand that some sealers / colour enhancers can help so am going to try Resiblock Sandstone Colour Enhancer on a discreet area. Has anyone used any other products that are worth trying?
Thank you.
