Q. - i was wondering what the diference in artist grade and regular grade acid stain ? we want the marble look and was wondering witch one we needed to use ? it is a new construction with a slick floor. thanks
Hello Mike,
A. - Other than the different color choices, the Concrete Camouflage artist grade is a one coat stain and the standard grade is a two coat stain. Therefore, you will get twice the coverage from the artist grade, than from the standard grade. On your concrete slab, you would expect a maximum of 400 sq.ft. per gallon using the artist grade, and 200 sq.ft. with the standard grade.
You can of course, do more coats of either stain if you choose, to achieve a darker color, different colors, or to do additional coats for artistic, highlighting, and/or camouflaging, etc..
As your concrete stain project is new construction and slick finished, you will first want to be sure that there is no curing agent on the concrete. If there is a curing agent, then you'll need to strip and/or lightly sand the surface to completely remove it from both the concrete's surface and pores.
Since you mentioned the desire to achieve as much marbleization as possible, you should be aware that the more you sand the surface the more that you reduce the marbleization. Therefore, you're better off to remove as much as you can with strippers, and keep the sanding to a light minimum, using more of a fine sandpaper, or a floor buffing machine with the fine sanding disks.
Otherwise, if you don't have a curing agent, as slickened concrete tends to close off the surface pores, thereby reducing the effectiveness of concrete acid stains, you will likely need to use a floor buffing machine with the aggressive scrubber pads during the cleaning stage, to really open up the pores of the concrete well, so the concrete stain can get in completely and achieve maximum reaction.
I hope this helps.
