What is the best mortar mix for Stone?
If you’re looking for a reliable, general-purpose mix, type N mortar might be the winner. This mortar mix has a medium compressive strength and consists of 1 part Portland cement, 1 part lime, and 6 parts sand. It typically achieves 28-day strength at approximately 750 psi.
Can you use mortar between stones?
Mortar can be used as a 1/2-inch to 1-inch-thick base under pavers as long as a 4- to 6-inch-deep layer of crushed rock is underneath the mortar to form a foundation. Mortar also can be used in the joints between pavers, just like grout is used between tiles.
Can mortar be used as grout?
Mortar should not be substituted for grout unless the substitution is allowed by the architectural specifications. Mortar often is too stiff to flow around steel into small cavities or cores without leaving voids. These voids not only reduce strength but also can lead to water leakage problems.
What is Type O mortar used for?
Type O mortar mix is low-strength (350 psi) mortar used in non-load-bearing interior projects. It’s often used to repair mortars and is generally used with sandstone and other materials with low compressive strength, since it’s very flexible. This mortar has very limited exterior use.
Can you mortar stone to plywood?
Using Stone Veneer Mortar. In this application, stone veneer is being placed over plywood. It is important to install a water resistant barrier prior to installing the stone veneer. Once the barrier is in place, metal lath is nailed to the plywood.
What kind of joint do I need to fill between Patio stones?
Once complete, the joint material has the appearance of sand hardened solid in which the sand particles are about the size of granulated sugar grains.

How do you fill a Granite worktop joint?
Push the resin into the joint using a filling knife working it in and ensuring that there are no gaps. Once the joint is totally filled you can remove the masking tape, leaving you a neat joint. Granite is a very heavy, very expensive material.
Can you put polymeric sand between flagstone joints?
Sure, but not forever. Polymeric sand is generally intended for dry laid paver applications. Natural flagstone, concrete paver and ceramic brick patios and walkways are set upon gravel foundations, their joints then need to be filled.
How is dry sand used to joint stone?
It is then scattered onto the surface of the paving and swept into the joints using a soft brush. Because the dry sand/cement mix is relatively light in weight, it rarely fills the joint properly; instead, it lies in the joint all fluffy and airy and not very convincing as a jointing medium.
