Can you repoint bricks in the winter?
I do not recommend repointing when the surface temperature of the brick masonry is 40 F or less. … Although Type III portland cement will perform slightly better than Type I in this situation, the advantage may not be enough to prevent freezing.
What is the lowest temperature for pointing bricks?
Below 40 °F to 32 °F (4.4 °C to 0 °C) Do not lay masonry units having either a temperature below 20 °F (−6.7 °C) or containing frozen moisture, visible ice or snow on their surface.

Mortar – Ideal temperatures for the placement and curing of masonry mortar is the range of 70°F + 10°F. In cold weather (40 degrees Fahrenheit and below) mortar materials need to be heated, otherwise the mortar is likely to exhibit slower setting times and lower early strengths.
How cold is too cold tuck point?
The quickest answer is both yes and no. The best weather conditions for tuckpointing work occurs in an air temperature between 40-90° F for the previous 24 hours and following 72 hours.
Does Frost affect mortar?
Freezing temperatures significantly reduce the compressive strength, the bond strength and also decreases the water penetration resistance of masonry. If the newly placed mortar does fall below freezing before developing enough strength, it will result in cracking, scaling and crumbling of the product.
What temperature can you do pointing?
The most ideal tuckpointing conditions will involve outside air temperatures between 40-90° F for the previous 24 hours and following 72 hours, with no heavy precipitation the day before or several hours after installation.
