FlGatorwood Posted February 24, 2019 Report Share Posted February 24, 2019 This concrete block house is 70 years old and little cracks that developed some years ago are now larger. I don't want the rain to get in so I plan to re-point all the cracks. First, I want to remove all the cracked mortar joints. Some folks say to chisel it out. I prefer to grind it out with a grinder or with my Fein oscillating tool. I would like experienced input and opinions. Does anyone know which is better? I think I can do the pointing ok. While chiseling, I don't want to weaken the inside mortar and have it crack open also. Thanks for sharing your opinions and experience.

Roly Posted February 24, 2019 Report Share Posted February 24, 2019 This is a good place for a cheap HF angle grinder with a masonry blade. The dust will eat up a angle grinder (and you) Wear eye protection and dust mask. Roly HARO50, Cal and HandyDan 3 Quote Link to comment Share on other sites More sharing options...

Nice clean surface to work with when done. So far no issues with it. Cal, HARO50 and FlGatorwood 3 Quote Link to comment Share on other sites More sharing options...
HandyDan Posted February 24, 2019 Report Share Posted February 24, 2019 what they said. Use a bonding agent when applying the mortar. Cal, FlGatorwood, HARO50 and 1 other 3 1 Quote Link to comment Share on other sites More sharing options...
JIMMIEM Posted February 25, 2019 Report Share Posted February 25, 2019 Angle grinder. A masonry supply company will have the correct blades (thick to clean the joint). This will be real dusty....there are shrouds for angle grinders that will direct the dust and a special shop vac will also help. If you have an assistant they could hold a homemade (plastic bottle) dust shroud on the end of a shop vac hose. Get the right shop vac filters.

FlGatorwood Posted February 26, 2019 Author Report Share Posted February 26, 2019 (edited) OK, it seems that we all have like minds. We prefer a rotary tool over hammer and chisel. And, just for Stick, I will get pictures of what caused all this ruckus. And, I will show what I have already chiseled out. I did purchase some of this to start my repairs. https://www.lowes.com/pd/QUIKRETE-Zip-and-Mix-FastSet-Repair-Mortar/3472653 It's going to be a couple of days after this rain deluge has passed over. Thank all of you for your help. Edited February 26, 2019 by FlGatorwood left out a word HARO50 and Cal 2 Quote Link to comment Share on other sites More sharing options...

Jim, you are absolutely right. Have to look the part just in case the local TV film crews show up. HARO50, Cal and Stick486 1 2 Quote Link to comment Share on other sites More sharing options...
FlGatorwood Posted March 2, 2019 Author Report Share Posted March 2, 2019 The lime is sounding tasty. May have to give that a try only it is doesn't set up in the gut. Cal, Stick486, p_toad and 1 other 4 Quote Link to comment Share on other sites More sharing options...

A prune juice chaser will take care of any potential set up problems. If you're using a quick set mortar then warm the prune juice in the microwave.
