Hi all,
Grateful for some advice about sealing grey sandstone. Saw on the paving expert site that the Advanced HD sealant was one of the best at stopping stains (which is what im after) in the trial. But it's not on the recommended list on the site (and it's cheaper than those that are). Anyone had any experience of using it (seems be called Advanced Sealing solutions Heavy Duty sealer now) or know why it's not in the recommended products?
Also any top tips for getting rust stains out of sandstone (caused by leaving rusty objects on the slabs)?
Many thanks in advance for any help
Tom
