FAQ

How much water should be used to obtain a quality mortar?

For best results, add a maximum of 145 mL (5.0 oz) of clean water per 1 KG (2.2 lb) of SAKRETE mason-craft, into the mixer. Gradually add SAKRETE mason-craft to water and mix with either a paddle mixer or drill mixer. Operate until the mix is heavy-bodied enough to retain its shape when fashioned, by hand, into a ball. Wait approximately 30 minutes before the application. It is important to mix the entire contents of the pail.

Why is it important to use only the recommended amount of water when preparing mortar with SAKRETE mason-craft?

Use only the recommended water content to achieve the desired plastic and hardened mortar properties.

What should be done if you need an N-type mortar or a conventional S-type mortar when applying a type O mortar?

For applications requiring conventional Type N Mortar, please refer to SAKRETE Mortar Mix, Type N; for applications requiring conventional Type S Mortar, please refer to SAKRETE Mortar Mix, Type S.

What is the yield of the SAKRETE mason-craft?

300 mL (10.1 oz) tube fills a space approximately 6 mm (1/4 in) x 13 mm (1/2 in) x 3.6 m (12 ft).

In which situations should SAKRETE mason-craft not be used?

SAKRETE mason-craft should not be used where Type N Mortar or Type S Mortar is specified

What is the recommended maximum depth for each layer of SAKRETE mason-craft when repairing a joint?

Place SAKRETE mason-craft into the joint in successive layers, to a maximum depth of 6 mm (¼ in).

How long should the surface of SAKRETE mason-craft be kept moist-cured?

SAKRETE mason-craft should be moist-cured for a period of 3 days.

What is the recommended temperature range for substrate and mortar when applying SAKRETE mason-craft?

The substrate and mortar temperature should be between +5 °C (40 °F) and +38 °C (100 °F) and maintained in this range for 72 hours after mortar application.

How to clean the surface before repairing the seal with SAKRETE mason-craft?

Clean the area to be repaired, removing all loose material, at a thickness corresponding to 2 times the thickness of the joint. Moisten the area to be repaired with potable water, leaving the old masonry unit saturated but free of standing water (SSD). Place SAKRETE mason-craft into the joint in successive layers, to a maximum depth of 6 mm (¼ in). Compact well and let dry slightly before adding additional layers. Tool the joints prior to the final set time, to optimize carbonation.

How long should the wet cure be carried out for the ripening of the mortar?

Curing is essential to optimize the physical properties of the mortar. Curing is performed by using a wet cure that must start from the initial set of the mortar and continue for a period of 3 days.

Is it possible to add on-site admixtures to modify the properties of the plastic or hardened SAKRETE mason-craft?

Never use on-site admixtures to modify setting time, workability, or any other properties of plastic or hardened mortar.
