Exclamation Small batches of thinset

Hello,

How do I measure thinset from a 50lb bag to make small batches?

That is hard to answer because of all the many kinds of mortars out there.
Many of the new flex mortars and highly modified mortars need to be mixed exact. That is to say in ratios per the bag instructions.
For a mortar like Versabond when mixing in a 2 1/2 gallon bucket I add a couple inches of water and pour in mortar until it looks like a valcano raising out of the ocean. 2/3rds of the mortar under water. 1/3 above. Stop there and mix it up. Add more mortar or water as needed to get the right mixture.
The mixing trowel will stand up by itself in the mortar.
Good Luck

define "small"

I did my first 2 rooms mixing batches in one of those flat blue buckets, but have now graduated to half-bag batches in 5-gal pails. You know what? Bigger is better. For starters, I no longer have to guess at how much water - just read the bag and cut it in half. I was always guessing and trying to figure out the proper consistency. Second the tile work goes much faster. Most thinsets have a pretty decent pot life in that quantity so you really have more time than you may think - and you spend a LOT less time cleaning.

Versabond and Folger's Coffee Cans

I take the mathematical approach. Versabond calls for 6 quarts of water for the whole 50 pound bag. I filled a Folgers' Classic Roast 39 oz can with vb and weighed it at 9 pounds on my antique farmer's scale. So 9 pounds is 18 percent of the 50 pound bag, so I needed 18% of the 6 quarts of water. There are 32 ounces in a quart, times 6 is 192 and 18 percent of that is 34.56 ounces and so that's how much water I used, more or less.

Now, to generalize, 34.56 is 3.84 times 9, so if you can figure out how many pounds of versabond you wanna mix, in pounds, multiply it by 3.84 and that's how many ounces of water you should add.

Now, if you don't happen to have a 39 ounce Folger's Classic Roast can handy, or an old scale, or if you're not using versabond, it gets complicated. The 39 oz can is your "big" can of coffee, but there's no standardization. A small can of coffee might be 11.5 oz or 13 oz and a big can could be more or less, I don't know. That's why ceramic tilers make the big bucks because they know what it's supposed to look like and what kinda trowel will stand up straight in it when it's just right. But, just use those math skills you learned in high school and you'll be all set.

I really don't know why you're looking at this when y'all should be answerin' MY QUESTIONS
