Concrete sealer quick fixes after sealing with a solvent based acrylic sealer:
Scratching/Scuffing: Scratching and scuffing are common problems. In order to prevent scratching on an interior application, use a floor wax for an additional wear layer of protection. In order to fix existing scratching, wipe Xylene on the area and reapply an extremely light new coat of sealer on the area.
Blotchy and Dark Concrete: Blotchy concrete can result from over application. In order to prevent over application, apply sealers in thin, even coats. If over application does occur, use Xylene to correct the problem.
Water Spots: If water dries on a concrete surface that has been sealed with a concrete sealer it will dry with water droplet marks from the minerals in the water. In order to prevent this from happening avoid sealing in an area where water sprinklers constantly spray. If water spots do occur, squeegee the water dry where hard water dwells on the concrete.
Roller Marks/Streaks: Roller marks or streak marks occur when the sealer was applied too heavily, unevenly, without maintaining a wet edge. Apply thin, even coats and if roller marks occur use Xylene to correct the problem.
Dried Milky White: Concrete sealers dry milky white if they were applied in a low temperature or when there is an extreme amount of humidity. In order to prevent this from happening make sure to apply sealer in the early morning or late evening when the temperatures are cooler.
Peeling/Flaking: Concrete sealers peel and flake when first applied if the application was too heavily applied or there are too many layers of sealer on top of each other. Delamination can commonly occur near the end of the lifespan of a sealer especially in high traffic areas or areas of direct sunlight. In order to prevent peeling and flaking of a new sealer make sure to wait until the previous sealer has worn away before applying a new layer of sealer. If peeling or flaking is occurring prematurely use Xylene to correct the problem and re-solidify the sealer.
Bubbling: Concrete sealers bubble when the application was too heavily applied or when a sealer has been applied in direct sunlight. In order to prevent this from happening apply two thin coats of sealer instead of one heavy coat. Also make sure to apply sealer in the early morning or late evening when the temperatures are cooler. If bubbling does occur use Xylene to correct the problem and get rid of the bubbling. Do not apply another coat of sealer thinking this would rectify the issue; it will result in solvent entrapment.
