Paint (stain) removal from concrete?

[BrianT]

Hi All,

I have read this forum for some time now but have not posted until now. Great forum with tons of info!

I have several customers that want their concrete driveways refinished. They were painted or stained (usually silicone acryilc base stain) more than 10 years ago. Anyone familiar with removing coatings from concrete. Chemical or abrasive?

Also any suggestions on high quality concrete stains/sealers would help

Thanks

what do they want done to the concrete? Do they want it to look like plain concrete again, or do they want it another or the same color?

nothing but a another silicone based sealer will work on any concrete AFTER SILICON HAS BEEN APPLIED.
My suggestion would be to clean it very well and go to home depot and buy concrete resurfacier and skim coat the whole driveway and start from their.

They want the driveway re-stained with a similar color. The old stain is worn in many places. A re-surface sounds too extreme.

If you are going to restain the drive way in a similar color,Then you could think about using a trezzo grinder.(ask the guy at your local rental yard). Use the lava rock blocks.The'll know what you mean.
The grinder is a good choice for cement overlays or sealing.The grinder removes surface contamination and helps to distribute uneveness caused from whether pitting,high traffic or abuse common with normal wear and tear.(it helps smooth it out so the new sealer looks more uniform).
A real reputable dealer in resurfacing products is Life paint speciality coatings.
