I'm using the sbr slurry to bond to the existing walls but thought that it might help to use the fiberglass mesh to stop cracks appearing as the house is next to a main road and this has caused it to crack before
If I apply an sbr slurry ( 1 part sbr - 1 part water - 5 parts cement ) to an external wall and want to embed fiberglass mesh into the render would I apply it straight onto the wet slurry and then immediately apply the sand cement scratch coat???
