Members BottomHeavyKate Posted November 20, 2009 Members Share Posted November 20, 2009 All right home improvement guys.... I want to repoint my chimney. I've worked with cement before, I've worked on top of a roof before....but I've never done any tuck pointing. While I'm confident in my ability to get this done well - should I wait for warmer months to do it? Will the cold weather affect the mortar? Any other tips?

Members bassman1956 Posted November 20, 2009 Members Share Posted November 20, 2009 As long as it's not likely to have a hard frost for the first couple days, you're okay. Steady 50 to 70F is supposed to be ideal. Won't freeze, won't dry fast. Also, a trick a mason at work told me is this: When you patch and tuck point with mortar, try to make the slot dove-tailed or t-slotted in shape, so that there's a wider volume in back to help hold the mortar in place. V-slotting is a guarantee it will not hold in long, and flat rectanguar slotting is the least you want to do. So, if you can't get any extra purchase in width, like a true dovetail, try getting extra in back at the ends, along the seam. Link to comment Share on other sites More sharing options...

Members Cpt. Spliff Posted November 20, 2009 Members Share Posted November 20, 2009 Honestly. Mortar will crack. The water in it will freeze. Link to comment Share on other sites More sharing options...
