Surface preparation before applying a sealer to existing concrete is extremely important. All oil, grease, stains, dirt, and dust must be removed or they may prevent the sealer from adhering properly. Also, if a sealer is being applied over a different brand of sealer, most manufacturers advise removing all traces of previously used sealers, since the products may not be compatible. Some manufacturers recommend etching the surface first with an etching solution to ensure the best adhesion.
