I recommend a sponge to absorb more of the mortar the rag smears leaving you residue
Good point, thanks for the tip.
Great job!!!
Still looks great almost 4 years later.
seems like you're supposed to mix the bonding agent with the mortar mix - I've done this before -- you just have to experiment with how much to mix so that it doesn't set too quickly
Hi Bill, I'm no professional on this subject but here's my interpretation from what I read up on trying to bond new mortar to old mortar. If you mix the bonding agent with the new mortar, that's going to make the new mortar bond more so to itself and mortar mix already contains bonding additives. If I apply the bonding agent to the old, dampened mortar surface first and then apply the new mortar mix over it, as I did in the video, that is supposed to help bond the two mortars together. This project was completed 3 years ago and it still looks great but that doesn't mean the other way doesn't work. I'm just not knowledgeable enough on the subject to know the bonding strength differences or durability. Now, there is such a thing called a "slurry" by which you add a bonding agent to Portland cement with water and mix and then, use the "slurry" as the bonding layer between old concrete and new concrete... but that process would not be necessary for brick work. Ideally, you would grind out all of the old mortar and replace with new mortar but I just didn't want to do that. I'll see how many years I get out of it but so far, it's as good and solid as the day I completed it. Thanks for stopping by.
which mortar has that color?
Rapid Set Mortar Mix in the brown 25lb. box... shown in video at 00:25 and 02:10 tends to mix looking gray but when dry, appears more whitish (04:23) in color.
A grout masonry mortar bag would have been a lot faster.
Duly noted but I didn't have one at the time or even think of it. I just got busy trying to get the project accomplished, thanks for stopping by.
Use lemon juice to get rid of the stains
That would be an eco-friendly choice for sure over muriatic acid (especially if it is used immediately after your finished) but despite lemon juice being a mild acid (citric acid), it may not have enough removal power for masonry residue stains. For internal home use and cleaning countertops, lemon juice and or distilled white vinegar solutions are excellent. Thanks for stopping by.
