Hi all,
I have just finished rendering a fairly large wall and forgot to add waterproofer to my render (5+1+1, plastering sand, cement, lime). The wall will be painted with exterior paint and should be pretty water tight. However, I am worried about water seeping up from the ground that could freeze and cause the render to come away. Is there any kind of material that can be applied to the render near the ground that would penetrate and provide some kind of waterproofing function. Or am I better off waiting for the render to fail and then replacing with appropriately waterproofed version? Any help much appreciated.
Best wishes,
John
