do-it-yourself questions with their 20 plus years of experience and knowledge.
The most common types of mortar are M, S and N. They correspond to compressive strengths of M=2500 PSI, S=1800 PSI, and N=750 PSI. The bond strength being less significant in some cases, it is better to use a lower classification or a weaker mortar, than it is to use a stronger mortar, because of the bond strength, and the extent of the bond. Bond is the amount of contact of the mortar with the masonry unit that is being used. As has been demonstrated in the past, bond strength is adversely affected by the compressive strength, therefore the relationship between mortar compressive strength and bond strength is that as the compressive strength decreases, the bond strength increases. Complete and full contact between the unit and the mortar is essential for water tightness and tensile bond strength.
Proper proportion of the mix is a very important factor. Large batches can have batch variations, and this has to be avoided, and can be following ASTM C-780. This is used to monitor variations of the mortar production.
A finely washed, dried and angular sand.
Proper proportion of mason sand to the mortar is a must, and being consistent
- Mixing Ratio (1) 80 lb bag : 300 lbs mason sand
Different applications as in grouting scratch coats will change mason sand and water quantities.
Metal lath used for thin veneer applications.
Available in 26" x 96" designed for overlapping installation.
Additives may be required in different application. Such additives are mixed with
mortar, concrete, etc. to increase adhesion between stone and mortar .
Acryl 60 is an acrylic -polymer emulsion mixed with portland cement mortars, plasters, stucco and concrete mixes to enhance their properties adhesion ton substrates, and durability.
Excellent chemical and UV resistant, which promotes long lasting repairs
- Will not re-emulsify when exposed to water
- Suitable for cold climate
Select Stone also offers equipment rentals only for use on products purchased from Select.

Efflorescence occurs when moisture introduced into the masonry wall remains there long enough to dissolve naturally occurring salts found within the masonry units, the cement and the sand. Through evaporation and wicking, these salts migrate to the surface of the brick, where they are deposited. If the proper amount of water is used in the construction process, and normal curing and evaporation takes place, visible efflorescence will be minimal. During the winter, however, low temperatures, high humidity, and rain can saturate a masonry wall. These conditions slow evaporation, making for a perfect environment for efflorescence to occur.
When the following three conditions exist, salts are precipitated on the evaporation surface:
- There must be soluble salts in the wall.
- There must be a source of water that comes in contact with the salts and forms a salt solution.
- There must be a pathway for the salt solution to migrate to a surface and evaporate.
