I am planing to use a mix of SBR and cement to waterproof a damp wall.
What ratio of SBR to cement would you advise?
This is going to be applied to an existing cement render then plastered on top, will the plaster adhere to this slury successfully?
Unfortunately this is about the only option open to me as the house is old and built of random stone, so there is not much I can do about adding a dpc.
The wall is an internal one and as long as this method works for 5 years or more I'll be happy to re-do the whole job again then.
