Setting Bed
- Use of Type N Masonry Cement is highly recommended for the setting bed cement mix. White Cement does not contain the chemicals that when activated by water can cause unsightly staining. Typical fine sand will be adequate for the cement mix. A setting bed depth of 1” to 1-1/2” is recommended.
- The concrete slab should be cured, and 30 days of curing would be ideal.
Grouting of Joints
- Grouting or Pointing of the joints can be done with the same Type N White Masonry Cement (mixed with White Sand to allow for accurate coloring). For an even more water repellent joint, the use of Urethane/Polyurethane sealant is recommended.
Waterproofing the Stone
- Alternatively, a cementitious based waterproofing could be applied to the backs and all unexposed sides of the stones to protect the stones from moisture sources and thereby prevent staining where a standard Type N gray masonry cement is to be used in the setting bed or grout. A recommended waterproofing product is (White) Super Thoroseal made by Thoro Products.
Delivery, Storage and Handling
- Product will be supplied adequately packaged on pallets or timbers to keep finished stone clear of the ground.
- Storage area should be a well-drained space graveled or chipped for protection against mud splatters.
When using pry bars to move stone into place, use padding to protect the edges of the stone.
Cleaning
- After mortar has set, the pavers should be brushed down with a stiff fiber brush, and then carefully rinsed with clear water to remove any accumulation of stain or matter foreign to the Limestone.
