Peeling Behr concrete stain can be repaired fairly easily. Peeling problems are usually due to faulty surface preparation. Once the peeling and loose areas are removed, and the surface is prepared properly, new concrete stain can be reapplied to achieve beautiful, long-lasting results. Interestingly, semi-transparent stains are more likely to peel than the solids. Keep that in mind when choosing the stain to reapply. All stain will wear over time. Choosing a shade close to the concrete it will cover will extend periods between touch-ups.

Remove loose or peeling stain with a wire brush and coarse sandpaper. Sweep or vacuum up the debris and discard.
Put on safety gear—gloves, goggles and work boots or galoshes—to prevent acid or chemical burns.
Use a rag mop or broom to spread on an even layer of Behr Concrete and Masonry Stripper No. 992. Leave on for several hours according to directions on the can. Scrub with broom and water. Rinse completely. Let dry.
Clean the mop and broom thoroughly with liquid detergent and water. Wring or shake out excess water.
Scrub the area thoroughly with Behr Concrete Cleaner and Degreaser No. 990 using a clean broom or scrub brush. Rinse completely. Let dry completely. Clean broom and scrub brush as instructed in Step 2.
Spread an even layer of Behr Concrete and Masonry Cleaner/Etcher No. 991 on the area with an old broom or rag mop. (Don't use anything metal, or the acid in the etcher will destroy it.) Rinse the area and let dry according to instructions on the can. Clean the broom and rag mop as instructed in Step 2.
Use a roller or clean rag mop to spread an even layer of Behr Concrete & Masonry Bonding Primer No. 880 to all bare areas, thereby increasing adhesion of the stain to the concrete. Allow to dry according to instructions on the can. Clean roller cover and rag mop as instructed in Step 2.
If the project requires multiple cans of stain, combine the contents of all cans to ensure uniform color. Pour them all into a large, empty paint bucket and mix thoroughly with a paint stirring stick. Important: Do not thin.
Apply an even, thin coat of stain with a clean, dry roller or paint pad. Touch up small areas with a clean brush. Let dry 24 hours. (Wrap roller or paint pad in plastic wrap, sealing out air between coats.)
Apply a second thin coat of stain in a crisscross pattern to even coverage out and increase richness and durability. Clean roller cover and paint pad with liquid detergent and water; squeeze out excess water; let dry.
Cordon off the area to dry undisturbed following these guidelines: Wait 24 hours before allowing light foot traffic. Wait 72 hours for automotive traffic or repositioning of planters or furniture. Park with the tires resting on heavy corrugated cardboard for the first two weeks after the 72-hour mark is reached.
Wipe up or hose off any spills and muddy footprints or leaves as soon as possible when they occur.
After two weeks, dry surface discolorations can be cleaned with a nonabrasive liquid detergent. Do not use stiff or wire brushes.
Keep up with touch-ups as wear occurs to avoid a major overhaul down the road.
