Hi,
Im going to use Vandex BB75 for the first time and Ive read two different methods for preping the substrate. Its a brick wall only just below ground and feels quite dry. The methods I have read are first brush and wet down then either 3:1 render beforehand, or direct application (brush/trowelon) of Vandex?? Which should I do?
Then I have a stone wall in the cellar.. very flaky.. again, which to use?
Any help gratefully received.
Cheers
Martin.
