Hi,
My question is can you please tell me what ratio of mix I should use for SBR when rendering concrete blockwork and also some areas where existing scratch coat is present?
BAL's date sheet has lead me to the following:
Slurry coat 1:1 cement and SBR let down with water up to 1:1:1 and brushed on.
· Whilst slurry coat is still tacky apply scratch coat (4:1) ,mixed with water/SBR mix (5litres of SBR, but this seems to much to me?). Allow this to dry.
· Render coat; (5:1), mixed with water/SBR mix (5litres of SBR?) Then wet dash on this.
The amount of SBR seems excessive, can you guys tell me what your doing?
