How is the water absorption test done?

Is the water absorption test done with small puddles of water or just a few drops? And how many minutes is pass/fail? Or does it depend on the product?

Some posts in this forum have recommended 1/4 cup of water, and Concrete Sealers USA's TS210 product application states "a few small drops of water". That's pretty far apart.

I just poured about 1/4 cup of water, divided into 5 puddles (1/20 cup each). One of the puddles absorbed in ~5 minutes, one in ~15 minutes, and the other 3 took about an hour. Not sure what that result means.

What is it exactly that you are testing for? The results all depend on the reason for the test.

So it depends on the product. Thanks @Shea .

I'm trying to figure out if there are any floor finish options that can simply be put down on the new concrete, or if I should just plan to grind.

I'll try "a few small drops of water" next to see if the TS210 is viable.

@Armorpoxy , what is the appropriate water absorption test for the 2-layer BallistiX system?
