Concrete Maintenance Guidelines

John Poullain, P.E.

This one-hour online course provides general guidelines and methods used for the maintenance of concrete. Concrete maintenance includes the repair of cracks, joints and surface damage. Maintenance also includes the removal of stains and the protection of surfaces with coatings and sealers. Among the coatings and sealers discussed are silicones, cements, urethanes, epoxies, latexes and polyesters. The necessary surface preparations prior to application of a sealer or coating are discussed. Concrete cleaning methods include water washing, steam cleaning, water and abrasion blasting and mechanical, flame and chemical cleaning. Stains commonly encountered are iron, oil, dirt, mildew, asphalt, efflorescence and graffiti.

Concrete stains do not usually adversely affect a structure but should be removed for esthetical reasons, for decorative types of concrete such as exposed aggregate and prior to sealing or re coloring colored concrete. The advantages and disadvantages and the most appropriate method for stain removal are discussed. Some methods will damage the concrete surface unnecessarily if not administered correctly. Concrete surfaces can be protected from deterioration from chemicals, acids, water penetration and dusting by the application of an appropriate coating or sealing compound.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
