Preguntas Frecuentes

What is the difference between mortar types?

Type M is strongest, Type S is medium, Type N is standard, Type O is softest. Choose based on structural demands and weather exposure.

What is the standard mortar mix ratio?

Type N mortar is 1:2.25 (cement to sand). Type S is 1:2. Type M is 1:3. Type O is 1:2.5. Add lime to modify properties.

Can I make mortar without lime?

Basic mortar can be made with just cement and sand, but lime improves workability and durability. Hydrated lime is recommended for most applications.

How long does mortar take to cure?

Mortar sets in 24-48 hours but continues curing. Wait 28 days for full strength before heavy loads. Weather affects curing time.

What consistency should mortar have?

Mortar should hold a shape when formed into a cone but spread easily with a trowel. Add water gradually until the right consistency is reached.
