Mortar Recommendations
Masonry cement/sand and plasticised cement/sand mortars are suitable for use
with
Key Stonework Cast Stone, however, mortars containing lime are highly recommended
as they have a lower permeabillity are give greater resistance to rain penetration.
Mortars must be able to resist frost and develop durability quickly, however,
unnecessarily strong mortars should be avoided as they concentrate the effect
of any
differential movement.
