Alpha, please rethink your rant. This article is being very general but he's more spot on than you. When I gauge out my epoxy with a 1/8 inch notched trowel, my spread rate is 100 sqft per gallon. Of course this is on a sealed or primed surface, which is what I think he's referring to without being to technical and boring.
Your spread rates are wayyyyyy off. When you refer to "any liquid for that matter" is off as well. You can't compare a low viscosity liquid to a high build. You can't notch out a water base epoxy and you can't spread a 100% solids at 1/64 inch.
Things work out much different in the real world Alpha. On paper it all sounds good but in application it's another world. Spread rates are meant as a guide and not gospel. As this article is, just a guide.
Have you done any floors yourself Alpha?
A. With the math he's not "spot on" - not even close.
Let's say someone is needs to put down a coating 1/64" thick, over 800 ft2. Reading the article
"a gallon of epoxy can yield 400 square feet at 1/64th of an inch" they order 2 gallons. It arrives, they apply the coating, and it fails. Why'd it fail? Because it was supposed to be 15 mils (1/64") thick, but instead is at most 4 mils thick, and after waste etc., actually probably less than 3.5 mils thick.
B. He brought up the 1/64" spread rate, not me.
C. You can spread a 100% epoxy at 1/64", which is about 15 mils, a very common size of notch squeegee. (1 inch is 1,000 mils. 1,000/64=15.625, so 1/64" is about 15 mils.) We do not recommend notch squeegees for under 12 mils - don't even offer them.
D. As a guide it has bad info - very bad. Someone depending on that info "in the real world" could end up with very unsatisfactory results. I'm just trying to correct that error - what's your problem with that? Why make this personal? What have I written that has anything to do with you personally or professionally? It's just math - I didn't reference you at all - why call me out? If my math is bad, point out where. If I insulted you, point out where, Otherwise whether I spend my time behind a keyboard, on a calculator, on my knees spreading epoxy, of drinking a beer, have nothing to do with spread rates.
E. Yes I have done floors - no, not near as many as you, most likely not even 1/64 as many as you, probably not even 1/64,000,000,000 as you. But that doesn't mean I can't calculate coverage rates, furthermore I'm not selling my services as an applicator.
Here's the thing - you go out and do jobs for people who don't want to do it themselves, I have no issue with that at all - never **** in on your posts, never question why someone would pay 4x as much for a job that the could most likely do themselves. Honestly sometimes I'd rather pay to have someone do a project for me - even coat my floor!
I work with people who would rather do the job themselves. So far I'd say we've done a good job at it. Is DIY a bit more risky for the consumer? Not necessarily - but it can be, just like changing your own oil, fixing your own faucet, painting your bathroom, etc. etc. I strive to get people the info to have a successful project. Getting the math right is an important part of that effort.
That's it. This article had bad info. Unless your wrote it (heck, even if you did) please don't take the corrections personally - that's not my intention.
