What It Is For

- Laying brick, block and stone, and repairing masonry walls.
- Tuck pointing and repointing existing mortar joints.
- Barbecues, pillars, planters and garden walls, the jobs a small bag actually suits.

Getting the Consistency Right
Quikrete gives a simple field test. The mortar is right when a half inch thickness of it will not fall off a trowel held close to vertical. Too wet and it slumps out of the joint, too dry and it will not bond.
Working Practices Worth Following
- Never mix a large batch for repointing. Mix only what you can use in about 45 minutes.
- Curing is usually unnecessary. Only in very hot, dry or windy conditions, and then a gentle water mist is enough.
- Protect from freezing for the first 48 hours. Use plastic sheeting or insulation blankets if it may drop below 32 F.
- Expect some colour variation. Mix water, mix time, curing conditions and finishing all shift the final shade.
- Wear impervious gloves, nitrile for example. Wet cement burns skin.
A Note on Water Behind Walls
Excess moisture trapped behind a masonry wall causes deterioration of the wall and rusting of any metal components in it. If you are repointing because water is getting in, find and fix the source rather than relying on the mortar to hold it back.
