Cannot really tell
Sent for a sample tin (which was not cheap) and the tin I was sent was very small - could maybe cover one or two blocks. I was expecting to be able to cover a reasonable area to try since it is quite an expensive product but could not. When I asked to return the sample unopened I was told I had to pay the postage myself. So a good idea to try a sample but it hasn’t worked out. In the end I cut my losses and put it down to a bad example of customer experience with that company.
