It's getting cold in the shop........

PostBy: oliver power On: Tue Nov 12, 2013 8:40 pm

Putting up a masonry chimney in shop. Had a hole dug 4 feet deep. Poured a 3-1/2' x 4' x 12" concrete slab for footer. Laid up 12 block so far. Film of ice in bucket this morning. So, didn't lay any block today. Seems I've heard/read of using anti-freeze when mixing mortar, but not sure. It's been many years since I've PLAYED with masonry. Never did it for a living. Any tips on laying block in these cold temps? Anti-Freeze, hot water, etc.. Thanks, Oliver Edit: I just realized I posted this in the wrong place. Sorry....

Warm water helps(but thats working with concrete,I'm not sure about mortar) but try to avoid doing it in cold weather unless you can keep it above freezing(maybe build a vertical tent with some heat :?: ) I would wait until the temps stay above 32* or warmer for a few days and then knock the job out.Keepaeyeonit

OP, next week is supposed to warm up--but YES a good pint of full strength anti-freeze in a standard mixer will work--always worked in Vt. when the idiots would call in the middle of the winter & need brick work done on their chimneys

Thanks guys. It is supposed to warm up some. I'm going to take both your advices. I've got 6 more groups of 6 blocks to do. I'm going to use hot water when mixing mortar. And do it in warmer temps. Should the temps take a dive, out comes the anti-freeze.

It is not an "accepted" practice, to put automotive antifreeze,
in mortar..

But obviously, there are those that have done it,
or "heard" of it done, and did not experience anything
wrong... to their knowledge..

The setting of concrete or mortar, is a chemical reaction,
it isn't actually "drying".
Adding chemicals other than clean water, can effect
the finished product. Because you do not know how the
anitfreeze chemicals react with the cement/lime in the masonry product.

It's best, to use heated materials, and keep the project from freezing temps.
Remember, you are just trying to keep the project from freezing.
So it does not have to be 75°. 40 will do it.

I hate to step on your professionalism, but anti freeze is tried & true by myself for years in Vermont's harshest elements & in 10 yrs never had a call back--or, YES you could complicate the hell out of it & go the proverbial BOOK route--KISS CS--PS-don't forget the coal ash content:)

Make sure your not laying mortar on a block that has a film of ice on it. Masonry in the winter is always fun, I think back to those days when I go to work and listen to certain idiots cry the end of the world when their room is 65 instead of 75 degrees :roll:

I 'did' say, that many have done it, and have no probems that they know of..
Glad you are one!
But keep in mind, that 10 years "should" be a drop in the bucket
for the lifespan of a masonry chimney.
Like you and I, the older we get, the more likely something is going to happen..
I could work like a bull.
40 years ago..

My experience was with concrete mostly, a cousin of mortar, so to speak..
The ASTM does not recommend it, that's all I was refering to..
(ASTM is the major testing and materials group)

Also keep in mind, I am the one that believes it's okay to use an MPD,
and it's okay to run two flue pipes in a chimney,
providing the operator/installer is somewhat intelligent..
So I am far from a "doom and gloomer"..
I'm not saying that the antifreeze chimney will fall down in the first
stiff wind. ;)
