Morning all
Need some urgent advice. I'm having the whole of my house rendered beginning on coming Wednesday. My builder is sub contracting out to another guy. So that I can quiz him correctly before he starts, can you give me some advice on which additives he should add to the render before applying please?
I happened to be in Wickes yesterday and saw more types than I expected. I live in Hertfordshire. Weather today is rain, but I'm hoping that its not going to become too cold.
The options they had at Wickes are:
- Frost proofer and rapid harderner
- Mortar plasticiser
- Waterproofer
- Waterproofer & retarder
Given its external, a waterproofer seems a sensible.
Do I need a frost proofer in current weather?
And does plasticiser make mortar too smooth? I want a smooth finish but not smooth like internal plastering else I fear the wall lights will highlight any imperfections.
All walls will be painted in due course.
Thanks vm..
