Rendering - Monte Dwyer
Monte shows us how to render an unsightly wall using the instructions supplied
with the Mitre 10 MitrePlan.
You can use “ready mixed mortar” which contains the lime cement and sand but you
will need to add an adhesive such as Bond-crete so the render sticks to the
Monte uses “Render- it” available from Mitre 10, the only thing you will need
to add is water.
The surface needs to be cleaned of all foreign matter such as dust and dirt,
mould and any unsightly protuberances such as loose bits of mortar. Try using
White Knight concrete etcher for a perfect surface preparation.
The mix needs to be just right; we add 1 part water to 5 parts “Render it”
and should be mixed to a smooth stiff slurry. The wall must be moist before
adding render. Build a ‘hawk’ (a handle on a board) and using a steel trowel
load the mixture onto the wall. Don’t cover breather holes.
Once wall is rendered wait for the cement to “go off” then smooth surface
with a wooden float.
Bagging a wall - Faye De Lanty
Faye uses exactly the same rendering solution as Monte except she adds more
water so the mixture has a ‘slurpy’ consistency. You can use a hessian bag to
apply the mixture however Faye prefers to use the head of a soft bristle broom.
As with rendering, scrub wall to clean and add the bagging mixture to a moist
wall using a circular motion depending on the desired pattern required.
When dry you can simply leave it or paint over.
