When it comes to floor epoxies, the way to pick/evaluate your vendor/supplier is not by what they tell you but by what the don't tell you

Putting down an epoxy on a cement floor can be tricky and lots of things (some outside of your control) can go wrong, almost all of which have nothing to do with the epoxy (so not the vendors' responsibility). Informing you of possible problems and possible ways around those problems could cost the vendor your business and send you off to a more 'cheerful and happy (and cheaper)' floor epoxy vendor web site. An example is an epoxy primer under the epoxy floor paint. It some situations it could save your butt, but more likely you'll just go to a site that doesn't mention using a primer (thus saving you money and time - but also a flooring failure).

What To Watch Out For From Epoxy Floor Vendor Sites:

1) There are water based floor epoxies and solvent free (sometime solvent based) floor epoxies. Some vendors don't explain the differences and use those differences to to make their product sound so much better (when it is an unequal comparison).

2) Epoxies yellow in sunlight (UV) and over time, especially the non-water based epoxies. This should be make know to you up front.

3) If your concrete is weak or crumpling (lots of dusting) - it could be your surface is not a good candidate for an epoxy floor, or at least one without a primer to 'firm' up the surface. Does your vendor mention weak or dusty concrete?

4) Lots of cement floors do not have a vapor barrier under them and those floors may have water - dampness issues (especially in below grade basement situations). Moisture issues under, on, and inside the cement could make an epoxy coating job a potential failure (there are some things you can try). You should be informed of this possible issue.

5) Many cement floors are full of air (cement can be like a sponge) and as the day warms the air in the cement expands and forms bubbles (popped or unpopped) in the starting-to-harden epoxy. The result is a disaster. Where you warned that this could happen? Diid they suggest fixes if your concrete has lots of air?

6) Old oil and grease stains can cause epoxies to peel right off. You may never be able to remove and degrease these areas no matter what you do to clean them. You should know this up-front.

7) Finally, do these vendors rely to emails or phone calls during the evening or on the weekends when you are working on your floor? Shoot them an email on Friday night and see if you get a reply before Monday or ever.
