Is this watered down cement or some other substance?

No it is sealant. I used it on my driveway to seal between the cement joints. It cures quickly. It self levels to give a smooth professional look after curing. It costs a little more but does a good job. You should use a rope filler in the cracks first and then seal over that. If you don't fill first the sealant will seep through the cracks and use more than you want. Good product.

It's a "regular" plastic model... so I suspect any plastic cement will work. I like the Testors model plastic cement, it's $2 and dries really fast

I'm not sure[google it] but it can yellow so I've started using a water base polyurethane.

we did not use a thinner and applied it full strength. it went on our boat bottom so don't know how it would work on cement.

It is. Just need to be cautious on the cement and to always empty the water out after you use it.

It appears to be the spray from the picture. However, if you send an email to the seller, he/she should respond.

I think there is some alcohol in the product, can smell it when I spray it on. I don't blow dry so don't have a good response otherwise.

Not sure what you are experiencing. I had no such problem but used it indoors last fall. If it is cool, it is likely to take longer to cure. Humidity in the air is also a factor and certainly if the concrete has water content from washing, the cure could be prolonged. Likewise, wrong ratio of resin and the hardener could do the same. And stirring it thoroughly is necessary. My advise would be to let it sit until it is NOT tacky. If that never happens, I would add very thin coat of sand and brush it lightly. eventually, it will harden up.

Calcium Carbonate, probably part of the fizz process when mixed with water.

Yes it's "extremely flammable," as per the label. Most cement mixes, in general, are flammable.

its more of a jelly or grease than a paste. similar to clear-ish petroleum grease

Not much that can be done that I have found. You can try to clean it with a mild soap and a stiff bristle brush. Concrete will remain lighter colored for a while, as it is 'clean' since OSPHO is an acid based product, it works similar to cleaning the concrete with Muratic Acid. Most places mine has dripped have eventually evened back out to the color of the surrounding areas.

It's definitely not completely clear. For me it was a very welcomed change because I was not originally a fan of the cement back on mine.You can check this post on Google + to see the difference it made.https://plus.google.com/107214661442313803427/posts/T3ccNR9XZgy

It might be chemical deposits from the water or normal staining. Feel with your finger if you can. If it feels rough, it's corrosion.

Guessing: Black + Solid probably = Old. Oxidized. Less effective as some of the components had either converted into other molecules or been deactivated by humidity.

It's water activated, it should be applied dry to facilitate the ease of spreading then watered in by self watering or mother nature, the problem if you were to apply it in the rain with a spreader it would get gummed up and clogged, the granules are very fine almost sand like.

No finish what so ever. It penetrates deep into the cement to fill in all the air spaces, thus not allowing water to soak into concrete and freeze which causes damage.
