I ended up having to buy a bag of Norcross Pro 50 leveller yesterday........they should be done under the Trade Descriptions ActThat's a good call to make a frost proof ,waterproof leveller ,
But one more for the list
Norcross pro 50 I've been told is suitable for outside but I would want to interrogate their tech about that a bit more before using .
