Working temperature for mortar

[lhuhn]

I have just started my first course for the oven dome and with colder temperatures here I am concerned about continuing to work. I can enclose the working area and heat it if necessary but for how long after I set brick. Can anybody advise me on working temperatures and how long I would need to heat after setting brick if the temp. is below the working range? Thanks

I wouldn't lay brick much under forty degrees F. You will want to keep it from freezing until it dries out, lest freezing water force apart your new masonry work. Needless to say, it takes longer for things to dry out in cold weather, to say nothing of the disagreeable nature of working with brick and mortar in the cold.

But if you can keep it above forty, and a ordinary halogen work light in an enclosed tent should be enough to do this, then by all means proceed.
