Hello,
I need to render some blockwork retaining walls in my garden. There are some drainage points in the wall, but it does get damp in winter and I can't tell whether it's coming from behind or it's just been rained on, which is why I want to use Lime render. The blocks are standard 7N laid flat.
Here's my rough plan:
Put 1/2 inch stop beading parallel with the bottom of the wall, a few inches above ground level.
Mix 1 part lime to 2.5 parts sand in a concrete mixer, adding water later on; not exactly sure as to the type of lime or sand?
Start with two one foot wide vertical strips about 5" apart and 10mm thick.
Fill in the gap, and level it to the vertical strips, repeating until wall covered.
FIx beading to external corners, check internal corners with a right-angled piece of wood
Key surface with a diamond pattern 1" between marks
Wait four days or so,
Apply thin final coat, then finish off with a sponge
Allow to go off for another couple of days.
When dry, paint with a lime wash.
I was just going to stop bead around the seep holes, 3" rectangles in shape/
How does this sound?
Thanks
James
