thinset questions

hi all,

i'm currently doing a bathroom remodel. i'm at the stage of retiling the floor and walls of the shower. i initially bought premixed thinset for this so i could use a little at a time. it's not for use in shower floors though. so i'm stuck with the 50lb dry bag of versabond. is there a way to mix a partial batch? does anyone have useful tips on how to do so or how you measure out a certain quantity? what do you do with leftover when you're done? toss it or can it be saved?

yeah you can mix little batches versabond has a pot life of about 4 hours working time, put powder in first after you put your mask on ans add water slowly want to make to follow instrucions should be smooth no lumps and for walls a little thicker is ok helps with slippage.

Unused thinset has a shelf-life of about a year, so 'old' thinset is never a bargain. Far better that than using 'premixed'...what are we talking here - a few bucks?

Yes, you can mix a small amount of thinset at a time.

I have done exactly that. You have to estimate approx. how much you will need for the amount of tiles you will use. The first time you mix will give you a guide for the next time, as to how much you need to mix.

Not too thick for floors, and make sure the ridges don't fall when drawing the notched trowel through.

Good luck.

Any small amount that I had mixed that was left over, I got rid of it.

thanks for the responses, all. i appreciate it.

my question was more just for convenience than cost savings. i don't want to be left with 20 lbs of dried thinset to dispose of. my trash service is 1 35-gal can picked up weekly. it has a weight limit too. i'll probably go through the whole bag within a week or so. i'm tiling the shower and floor in a medium sized bath.

Do not use any pre-mixed product for setting or grouting tiles. Mastic should only be used on dry vertical surfaces like a kitchen backsplash. Not only in thinset better, but it's much cheaper too.

When mixing thin set, pour water in the bucket, then add the powder as you mix, not the other way around.
