Howdy,

We were about to do a glue down floor over our (2nd floor condo) concrete subfloor, when I spilt Tung oil over some of it and some of the SLC we've used. I put some cornstarch on it for now, as advised somewhere else, but it seems to little, too late. Any advice on chemically cleaning this? Grinding is no longer an option, and I want to be sure any chemicals we may use won't interfere with glue.....which actually brings me to another question: our Bosticks BST is over a year old now (we bought it over a year ago)...but we've been told it's still okay? Is this right? I guess we won't know till we open it...

Thanks!!!

I would flat trowel / skimcoat the spill spot with Ardex, just to encapsulate it.


The glue should be fine. You might have some thick stuff up on the top under and around the plastic.

One year old?

Probably can't use it. I've run into one that looked like it hadn't been rotated in a warehouse. Sure enough, it was solid all the way through after pounding a long handled screwdriver through it when the lid was taken off.

Shelf life is a big deal with MC urethanes. I'd be suprised if it were not a tubular brick by now.

Thanks for the replies!

hmmmm, so we have no Ardex in these primitive parts (bc, canada)
or not as far as I know...
...and the glue...well, if its turned into a brick, that will be a nice expensive new and funky stool, haha...well, actually, I'm not laughing...

So as a last note, the glue was not a rock, in fact, it was somewhat useable. But we did end up buying a new pail, also for the reason that we are dead slow and were losing a lot of that pail due to the glue sludging/curing after we were done each day...

The tung oil area was removed by myself and a chisel..
