Bought 2 tins. The 1st went on well and looked very nice. Really pleased with it. Started the 2nd tin and it would not mix well when stirred. Very streaky with tints of white. When applied came out very patchy with no consistent colour and looked really poor. Not sure if it was a faulty batch or old stock.

Easy application

Great coverage has a fine grit to this anti slip would recommend, when it's on your hands and it's hard to get off this means it's good stuff will buy this again to do my shed next as its hard wearing for walking on so it will last longer

This stain which is supposed to be slate when first applied looked fine but as you work down through the tin even with stirring it soon becomes lighter and lighter. Very poor and would not but again or recommend

I bought this yesterday, picked it up today,
Says slate on the tin, it says try it first, but when you have a nice day you have to just get it done. It's not slate it's very light grey.
