Lime is sold as mason's lime
, quick-lime or just plain lime in waterproof sacks that hold up to 60 pounds.
A high calcium lime sold in feed stores is perfectly acceptable to use, but Type N builder's or Type S mason's lime
are considered better because they must meet ASTM standards for performance in construction.
Mortar is made from masonry cement (a combination of Portland cement and hydrated mason's lime
), fine mason sand (also known as fine aggregate), and clean water.
