How to stain concrete – bob vila
STEP 1 To stain concrete successfully, the first step is to prepare the surface, being sure that it’s free of residual adhesive, flaking paint, and similar debris. Scrub the concrete with a solution of TSP and water. Treat stubborn stains aggressively with a degreaser orВ chemical paint stripper. Mechanical abrasion is a last resort.
STEP 2 Tape off any sections of the concrete surface that you do not wish to stain. Do this very carefully, as it may prove impossible to remove the stain if it lands somewhere you didn’t intend it to go.
STEP 3 To get an impression of how the stain is going to look, test it in an inconspicuous corner or along a remote edge of the concrete. Don’t love how it looks? Adjust the stain accordingly, diluting or intensifying it.
STEP 4 Now you’re ready to start applying the stain. The goal here is to achieve even coverage. To that end, many choose to employ a sprayer (whose parts are plastic so as not to corrode upon contact with acid). After spraying-never so much that there’s puddling-use a shop broom to ensure that no parts of the surface look relatively darker or lighter. If necessary, spray again to eliminate marks left by the broom.
STEP 5 Different stains take different periods of time to set properly; consult the label on the product you have chosen. While the stain is setting, the chemical reaction actually continues. It ceases only when you neutralize it by washing the floor in a solution of water and detergent (and sometimes baking soda).
STEP 6 Finish up by protecting the stained concrete with a sealer. Again, consult the product label; it’s a good idea to use the manufacturer-recommended sealer. Indoor concrete flooring is usually sealed with wax, although in a high-traffic area, I would opt for epoxy beneath urethane. Note that you can use a buffing machine to facilitate the sealing process, so long as you are working on a floor surface indoors.
