Stain concrete floor

[Buzzards]

--------------------------------------------------------------------------------

I stained my garage floor with a water based stain, Eco-stain . As per instructions i was to clean and profile [ etch or rough up the surface] with a liquid product SCR[ SUPER CONCRETE RENOVATER ] From what i gather a smooth surface will not let the stain penetrate. That is why SCR is used.
After all was done the stain just sits on the surface, it did not soak in. I can wipe it off with a rag easily. Not sure if i have to sand the surface or ? Has anyone used this product? It is a very user friendly product compared to an acid stain, if it works? Thanks in advance

And that is the trouble with water based stains, they do not react or penetrate well.

Contact the mfg on best practices for the product.

I used a xylene based Coronado concrete stain on my floor (15years ago) and now I can't find it to recoat my floor...... It was so good they stopped making it.
Water base stains on concrete floors are "poor" at best....... You have been warned!!

I'm no expert but I just finished doing a bedroom floor in our house with water based stain. It almost caused a divorce.

Water based stain and water based clears are utterly intolerant of ANYTHING soaked into floor. I cleaned our floor until I was blue in the face. Scrubbed in assorted spots with chemicals including but not necessarily limited to: boiling water (great for carpet glue), mechanical scraping, simple green, purple power, mineral spirits, acetone, lastly Blue Bear 700DG degreaser and scrubbing with a rented floor maintainer and black scothbrite disc over the whole floor and several rinse and vacuum up cycles. Then sanded the floor with the floor maintainer and silicon carbide 80 grit discs for the floor maintainer just enough to "open up" the surface followed by more rinse and vacuum-up cycles. We are talking about maybe 4 man-days of work.

Even so - I had a 2 ft dia spot that did not take stain. I dedicated a full day of chemical warfare and spot sanding to that friggin spot and water was still beading on it when I tested. In the long run I wiped stain onto the spot though the rest of the floor was sprayed with an HVLP gun and got it to take thought the spot was still obvious.

I knew water based clear would not work based on the stain issues so opted for solvent-based clear even though the stain mnfr said their WB stain was not compatible with methyl methacrylate clears.

If you have an idea what is in the concrete that is causing the issue you will have a better idea how to attack it. If water beads on your concrete you have no hope of getting WB stain to take. I had a little dropper and kept dropping droplets onto areas to test. If the drop beads you are not finished cleaning. As I said I gave up on the one spot and cheated.

The floor is beautiful now but it was a living nightmare for a few days. We'll see how it holds up.

Best of luck to you.
