Discoloration

Discoloration - Causes, Prevention, Repair

Discoloration occurs because of metal in the concrete, aggregates, add mixtures, fast sets or stains and spills. In order to keep discoloration to a minimum it is vital that you do not put something on your concrete that encourages a greater discoloration of the concrete. Acrylic, Silanes, and some Siloxanes will actually add to the color change of the concrete, making discoloration even worse!

V-SEAL is a clear, flat, sealer that can't flake and won't yellow. Also, V-SEAL will NOT change the color of your concrete.
