Why did my concrete sealer turn yellow?

Some sealers use resins that are not light stable. Long term exposure to UV sunlight can cause them to become yellow or brown in appearance.

How do you fix blushing concrete sealer?

How do you neutralize Xylene?

Submerge the xylene-coated object in the water, and allow it to boil for as long as possible, at least one hour and up to four hours. Allow the object to air dry overnight in a warm area. The hot water followed by exposure to warm air will help to eliminate xylene from the surface.
