Can I Use Old Grout That Is Still like Fine Powder?

chipster_2007March 4, 2012

I have a box of TEC powdered unsanded grout that was opened over a year ago but was sealed with duct tape. It still looks and feels like fine powder, no clumps. Is it still good and can it be used? What are the telltale signs of dry grout that has gone bad? Thanks

I was wondering the same thing because we have two half full 25 lb bags of Laticrete Permacolor leftover from our just completed masterbath reno. If they don't have a shelf life once they're opened, I thought I'd either give them to my tilesetter or see if Habitat for Humanity would have use for them.

Unless it's in water-tight containers, shelf life is about a year. With containers, meybe longer. Mix up a little bit and let it set up at least a day and see how hard it is.

Having said that, grout is cheap...if in doubt, toss it.

Toss it. That's a year from the date of MANUFACTURE, not date of purchase. Not worth taking the chance on.

I didn't know grout would go bad. How does that happen if it is kept dry? I would love an exclamation.

Two words-- ambient humidity. Even in the little bit of air trapped in airtight bags. It doesn't take that much moisture to set off portland cement.
