[MBZ] OT: Thinset mortar and bricks
I just did a project where I used about 2lb [1 kg] of thinset mortar intended for laying tile from a bag of 50 lb [22 kg]. I am also needing to do some tuckpointing on a brick chimney. So is it okay to use the thinset?

It does not have a lot of sand in it, or the sand is finer, something. It is different from mortar, probably the mix of lime cement and sand. I know it is hard to waste a whole bag but the repointing mortar is cheap enough and would be the correct stuff. That said, it would probably work but how long it would hold up would be the question. --R On 2/24/14 1:49 PM, Fmiser wrote: I just did a project where I used about 2lb [1 kg] of thinset mortar intended for laying tile from a bag of 50 lb [22 kg].

Rich, On a similar note, the restored Williamsburg area has many walkways and paths. They did not want to be forced to constantly restore the paths which see a lot of foot traffic every year, or use something that was obviously ahead of its time. They ended up mixing Portland cement with x pounds of cracked, yellow river pebbles. They use cracked because the rocks will lock into adjacent rocks and with the cement, recreate a sturdy walkway which only needs to be touched up once a year. The paths look gorgeous also..

Re: [MBZ] OT: Thinset mortar and bricks
I agree, don't do it. Regular masonry mortar is a better bet, cause it has more sand and such in it, and is designed to fill larger gaps than thinset. I guess you could go get some sand and mix it in the thinset to produce a masonry mortar of types, but I'd only do that in a real unusual situation ( deserted island ) cause masonry mortar is so cheap.

So is it okay to use the thinset? I'm not a mason! -- Philip It depends: Others have pointed out some of the potential pitfalls. THinset is made with finer sand, and with a very rich mixture of portland cement and possibly lime and latex. Portland cement = compression strength Hydrated lime= tensile strength Latex = stronger bond (and increased tensile strength. So, if you mix 50% sand and 50% thinset, you might be close or maybe 1/3 sand and 2/3 thinset. but some ratio will get you a good mortar if mortar color does not matter. If you have a large job and will use more than your bag, you may want to keep the thinset for other uses and mix your own mortar for tuckpointing. HOWEVER: If you are trying to match the original mortar, the thinset may be too light in color. Bagged mortar mix does not contain lime. It tends to break away from the bricks if anything shifts. (like the next great New Madrid fault earthquake) Liime and Latex both make the mortar lighter in color Historically, most mortar used before 1900 was sand, lime and horsehair/straw Early 1900s was cement and lime and sand Post WWII was mostly portland cement only with sand. Some good masons still mix their own I'd laid thousands of bricks, and I always mix my own.
