Stucco Mason

I am currently getting my chimney rebuilt with 4" block and the temperature is 35 degrees F. The mason will be putting on the scratch coat of stucco then applying the finish coat in 3 days. Is this OK or is it too cold? Please help. From what I can tell… Stucco hates cold temperatures. IF you are using stucco in climates of freezing temperatures, I hope the stucco is acrylicized. IF not, water will get in it, freeze, and the stucco will shale. Stucco should not be set at temps that concrete would not be set at. The cure rate is very very slow. IF it is applied at too cold temperatures, sag will result.

    Yes it can be too cold to apply stucco. Good thing summer is coming though. I was getting tired of how cold it was. Bill |

    It's okay as long as the temperature is not below freezing.

    The temperature needs to be a minimum of 40 Degrees F. And should not drop below 40 degrees for two days after application.

    It's ok. . . . . . . . . . . . It's hard to do but we use to get it on around 10 in the morning so it could get some warmth between 11 and 3, once it has lost it's heat, the results can be a little tricky. . . . . . . . . Build a tent over it and have a couple of light bulbs going if you think it's going to freeze. Good luck.
