Concrete Stain: Is it possible to put latex concrete stain over acid stained concrete?

ok. This is not my specialty. however , Ive been a painting contractor for like 19 years:





You SHOULD be able to do this.





Recommended approach:





1) if you have the label of the acid stain, read it and see what it says. You wanna find out if a bonding primer is needed or some such thing.





2) If cannot: do you know the brand/manufacturer? Check with them.





3) if no dice on ay of the above: is the surface hard and slick and VERY sealed? IF yes, then probablly cannot go over it with a latex. If its somewhat poreous and rough then it should be okay.





Experimental route: go buy a quart or gallon (gallon is for sure enough to do any project under 500 sq ft.) and put a small sample. Let sample dry for manufacturers suggested time. Try scraping it off with a fingernail and some scraping tool - that test will tell you if its gonna stick or not.





- if its tough like hell to get off, thats great for you. If it peels easily (like a baloon skin) - then be happy you didnt do your whole floor.





The basic rule here is that you want the topcoat to be able to adhere to the substrate. If its like glass, then a latex product doesnt have anythng to grab to - and it will fail.





If its just a stain (with no clear coat atop it) youre chances are pretty good. If theres any kind of sealer atop it - well.... that sucks. Stain wont penetrate a sealer - thats the purpose of the sealer - to prevent stains....





you can solve this one.
