Sealing & Coating Compounds
Concrete Repair and Maintenance

Concrete sealing and coating compounds are applied to cured, dry concrete as a maintenance and repair procedure to reduce or prevent penetration of water, aggressive solutions, or gaseous media.

They help to reduce or prevent associated deterioration such as corrosion of rebar, freeze-thaw, carbonation, or sulfate
damage. These materials are not suitable for repairing badly damaged or deteriorated concrete, but they are suitable for
sealing concrete surfaces and cracks in concrete that is in overall good condition. In many cases, small areas of damaged
and deteriorated concrete can be repaired prior to application of one of these products.

According to the U.S. Dept. of the InInterior’s Bureau of Reclamation’s “Guide to Concrete Repair,” cracks in concrete are widely regarded as a long-term durability and maintenance problem because they increase the permeability of the concrete. Cracks can allow ingress of moisture and other compounds into concrete, leading to further deterioration. Cracking is a problem that occurs in most geographical locations and climates, and in many types of concrete structures.

Reclamation has a large inventory of aging concrete that is experiencing deterioration resulting in cracking or exacerbated by cracking. Effective sealing and coating compounds for smaller cracks could slow or halt deterioration in some cases.

A variety of different membrane forming (paints or coatings) and surface penetrating chemicals are manufactured and sold as sealing compounds for concrete surfaces. Some of these materials provide very good protection to the concrete for discrete periods of time (ACI 515, 2013). Other commercially available sealing materials, however, may consist of little more than mineral spirits and linseed oil.

Such systems will, at best, do little harm to the concrete.
Their application may, however, prevent subsequent treatment with sealing compounds that have proven more effective.
For this reason, only products that have been proven effective in standardized laboratory evaluations should be used.

There are three basic categories of protective surface treatment that can be performed on concrete. These treatment methods include:
(1) The concrete surface can be treated with a coating that essentially covers the surface. These surface treatments are typically polymeric materials, such as epoxy, polyurethane or polyurea. Full story »
