Question: Can I put it over an acid stain floor and can I use a Spartan coat sealer over this product. aslo do i have to scrub this in or wash any residue off after this densifier is applied?
Document: I bought this particular concrete sealant to protect our new garage floor from spalling during the our course of new construction.Winter has been starting early here this year with overnight temps dropping into the low 20's and were just getting into October. Product was easy to apply with a cheap garden sprayer. Requires two coats, the first one pretty much soaks in and after about 4 hours you can apply the 2nd. coat which actually seals the concrete pretty well.
I bought this product to prevent the build-up of salts on my garage floor when moisture was present. After meticulously cleaning the floor then drying it, I applied two coats over a span of 3 days. Water from our cars' air conditioners, water from a small leak in water heater pipe, water dripping off cars after rain, etc. have all resulted in large build ups of white salts extruded from the concrete. THE PRODUCT DID NOT WORK IN THE IN THE LEAST BIT!
Excellent product that got the done for me; used it to protect the garage floor from spills, leaks, and salt solutions tracked in  during the winter months.
This is frustrating in that I invested 3 days labor and over $150 in the project!
