Pointing
- Ideally,
pointing should be done within 4 hours of a paving being layed
and ideally in a dry but cool part of the day.
- Make
a mix of 4 parts building sand to 1 part cement, just about
enough so it clumps into a ball when compressed in the hand.
It also helps to use a plasticiser.
- Using
a pointing trowel, feed mortar into joints, being careful
to avoid staining the slabs. Pack down with the trowel. 'Polish'
mortar with a rounded pointing bar (e.g. a short length of
copper tube.)
-
When
mortar starts to set use a soft brush to sweep ACROSS the
joint to dust off any mortar left on the surface of the
slabs.
