If I use the Britannia Aquashield High Build, https://www.rawlinspaints.com/home/...n ... build.html, as some gaps/holes could be wider than 3mm, which cheap scrim / alternative could I use under the paint?
Could I paint, put scrim then paint again?
Or should I use the two items below instead:
[IMG]Acrypol + Waterproofing - Grey 2.5Kg
and
Acrypol Flexible Reinforcement Scrim Tape - 150Mm X 20M
