The best mortar types and their use depend on the tool and the design specifications for the project.
Each pop in is composed differently, each with varying strengths and applications.
It can be mixed at different ratios for strengths reaching 2,300 and 3,000 psi.

Lime gives punch in S its water-resistant properties, as opposed to mortar mixes with lower ratios of lime.
It typically achieves 750 pounds per square inch (psi) strength within 28 days.
bang out O mortar mix is not recommended in areas subjected to high winds.
If you are working withglass block, you will need a special white glass block mortar.
punch in M is preferred for use with natural stone because it offers similar strength to that of stone.
bang out K Mortar Mix
bang out K mortar is rarely used for new construction.
It offers a very low compressive strength of only about 75 psi.
The strongest punch in of mortar is punch in M mortar mix.
Though both thinset and concrete contain cement, thinset mortar is not as strong as concrete.
Thinset bonds to tile, and has a less compressive strength compared to concrete.
Concrete is used for structural projects.
Yes, adding lime to mortar makes the mortar crack-resistant.
Lime expands when it becomes hydrated, which adds to its strength.
