Repairing Deteriorated Mortar Between Landscape Bricks

A homeowner needs to replace missing/crumbling mortar between landscape bricks and asks if sand mixing is required.

Mortar Basics

Mortar = sand + lime + water + cement. Types vary by ratio (N, S, etc.) for indoor/outdoor/water-resistant applications. Mortar composition guide.

Application Methods

• New brick laying: Wet mortar technique
• Repointing existing: Repointing guide (wall concept applies to patios)

Practical Tips

• Big-box stores sell pre-mixed "patch kits" (just add water)—convenient for small jobs
• Read bag labels for coverage, water ratio, and working time
• It's messy labor—consider hiring a mason for large areas

Match mortar type to exposure conditions (exterior = Type N or S typically). Proper joint preparation (clean, damp) ensures adhesion.
