  1. Vladimir – VG Groundworks

    Goes on Nice and thick. Really good waterproofing for buried roof. Came next day and cheaper than other shop. Happy.

  2. Umberto – UK Wallcraft

    I use this all the time for the outside of block walls, it’s thick enough to get in to all the nooks and crannies and into the corners. There’s a bit of a knack to using it, you have to be good with a trowell, but great product. Good service too.
