Did a couple last year. I think they changed the rules, better check. Also, I never let the dish sit out open, everything is ready and weighed prior to setting. Will you grind it and come back the next day or just plop'r down on the existing surface?
Ya, I think you'd better state the ??? It's almost 7 pm here, been a long day and I had a relaxing beverage or two already...in other words, I'm stumped.
You're right about the extra trips for sure. I just charge for the extra mobilization and tell them that's the ASTM testing standard. If they don't like it, they can call somebody else and waste time and money.
As far as RH for epoxy, I'm waiting on word to proceed with RH testing at another epoxy job, but this one's failing. Turns out someone did CaCl, but not sure if it was done per F1869. More on that one later if I get it.
Good ol' MVER. You must feel so nostalgic JK! We still have some carpet manufacturers who spec MVER. The Carpet Standard has not been reviewed for a while, at least not the testing part. I'm dreading my first official test job being MVER.
Do you leave 24 hours between grinding and placing the kit regardless of the subfloor? 1869 says you don't need to for new concrete or where coverings were removed minimum 30 days prior so I'm assuming that it's a good idea to do it anyway.
Also, pardon my ignorance, can someone explain the difference between lightweight and heavyweight- I know it's to do with the density of the aggregate but is there a clear boundary of definition or is it a shade of grey- if that makes sense..?
