Masonry Adhesive vs Mortar: Best Applications
Glue Strength and Durability
When comparing masonry adhesive and mortar, understanding their strength and durability is essential to choose the right application. This section discusses tensile vs. compressive strength and durability in various conditions.
Tensile vs. Compressive Strength
Tensile Strength:
Construction adhesive generally has higher tensile strength compared to mortar. This means it can stretch and flex without breaking. Tensile strength is crucial in dynamic environments where minor shifts and vibrations occur. For example, construction adhesive works well for non-structural components like securing a tile or attaching decorative elements.
Compressive Strength:
Mortar, on the other hand, excels in compressive strength. It bears heavy loads without crumbling, making it ideal for load-bearing applications such as brick walls and stone structures. If structural stability is the primary concern, mortar is the better option (Homey Cons).
| Strength Type | Masonry Adhesive | Mortar |
|---|---|---|
| Tensile Strength | High | Low |
