Concrete Coating

Last updated: December 7, 2018

What Does Concrete Coating Mean?

Concrete coating is the covering, typically liquid or semi-liquid, that is applied to cured concrete for aesthetic reasons as well as to make the structure or surface last longer and to reduce maintenance and repair costs. For instance, a protective and aesthetic coating like paint can give color and a smoother surface to concrete walls and floorings while protecting them from wear, abrasion, reinforcement corrosion and harsh environmental conditions. Another type of concrete floor coating can protect them from the wear of daily traffic or make them slip-resistant and easier to maintain.


Corrosionpedia Explains Concrete Coating

Aside from aesthetic reasons, it seems that a concrete coating is not necessary for this tough and durable mixture of cement, water, sand and gravel, which is not known to rust after it hardens. While it’s functionally possible to use a bare concrete surface or structure, it can degrade over time due to the various harsh conditions that indoor and outdoor concrete surfaces are subjected to such as the following examples:

  • The heavy foot traffic, abrasion, water and chemical spills on indoor concrete flooring.
  • High and sub-freezing temperatures, moisture, chemicals, ultraviolet (UV) light, heavy vehicle traffic on concrete sidewalks, bridges, parking areas, roads and walkways.
  • Loads and moisture penetration from rain, snow on concrete walls, building foundation, roof and pool decks.
  • Corroded reinforcement of the concrete. Rust expands, causing concrete to crack.

Coating will not infinitely protect concrete but it will delay its degradation and extend its useful life with the least possible maintenance and repairs.

The type, purpose or function and location of the concrete structure are the major factors in selecting the appropriate coating to apply.
