Concrete Coatings

Today, concrete is the most used building material.
Industrial structures utilize cast-in-place concrete for foundations, floors (both on and above grade), and structural columns/beams. Cast-in-place concrete is also used to hold or transport industrial fluids as sumps and trenches and as secondary containment for process units and storage tanks.

Our Concrete Coating Service

Compromising on the surface preparation will diminish the effectiveness and shorten the service life of even the best coating system. We use methods such as acid etching, grinding, and abrasive blast cleaning to achieve the required surface preparation for coatings systems.

Coating Vs. Paint

It can be easy to think of concrete coatings as just paint, however, these coatings have different properties. While providing general color and texture options, coatings have superior protective qualities and are meant to withstand more extreme weather and environmental conditions.

Conomos has the technical competence in all concrete coating applications and offers the following services:

  • Concrete Floor Coating: Commercial & Industrial
  • Concrete Walls: Cast-in-Place & Pre-cast Tilt Up Walls
  • Containment FacilitiesTank Coating and Lining & Secondary Containment

Industrial and Commercial Concrete Coating

Concrete Floor Coating

  • Conomos has completed flooring projects in both the Industrial and Commercial sectors. From athletic arenas to warehouse and manufacturing facilities, our experienced crew will deliver a quality finished product.
  • The coating of floor surfaces must recognize the potential of stresses from foot traffic, light vehicle/forklift traffic and heavy truck traffic.
  • For safety purposes, floors must be skid resistant, either through grit mixed into the coating prior to application or grit broadcast into the applied wet coating.

Concrete Walls

  • The rationale for coating of concrete walls is similar to coating building interior or exterior surfaces.
  • Coatings will extend the life of a concrete wall and the appropriate coating systems selection is dependent upon the surface’s operations exposure. For example, moisture, chemical fumes and steam can all be considerations for system selection.
  • Surface preparation for coating concrete walls follows the same protocol as floor coating and should only be applied to a clean, sound surface.

Tank Coating and Lining

When it comes to tank lining projects, or containment of materials within the tank, longevity of service life of the tank is of the utmost concern. This can be tricky when considering what the tank was built to contain.

  • Will the tank hold water and for what purpose will that water be used?
  • What if the tank will store chemicals?
  • Is the tank open at the top and will it be exposed to the elements?

Conomos will be happy to work with you and the coatings manufacturers to determine the best product for your job. For more information, visit our tank lining service page here.

Secondary Containment

  • Secondary Containment areas are built as a back-up plan to contain spills from tanks and other industrial equipment.
  • Naturally, an area that is meant to contain liquids and chemicals from going elsewhere needs to have a quality coating system of its own.
  • Conomos has completed hundreds of secondary containment projects and has the expertise to make the finished project look good in addition to functional.

Surface Preparation Requirements

Compromising on the surface preparation will diminish the effectiveness and shorten the service life of even the best coating system.

Concrete must be free of dirt, oils, form release agents and grease. Concrete laitance (the fine wet slurry that “rises to the top surface” of a concrete pour) has no strength component after the concrete dries and must be removed, either by high pressure water, abrasive/shot blast cleaning or mechanical abrasion. At Conomos, we use methods such as acid etching, grinding, and abrasive blast cleaning to achieve the required surface preparation for coatings systems. The best concrete surface for coating adhesion feels like sandpaper.

All cracked or faulty concrete must be removed and any surface voids first exposed by blast cleaning must be filled and smoothed even with the concrete surface.

Selection of the proper concrete coating system is primarily a function of resistance to the chemical composition of the contained fluid, that material’s maximum/minimum operating temperature and the “abrasiveness” of that material.

A concrete coating system can be as basic as a primer with a thin film top coat, a primer with multiple flake filled spray applied topcoats or a primer with trowel applied topcoats. Sometimes the trowel coats will sandwich a layer of fiberglass reinforcement.

The final coating system may be a hybrid system of reinforced trowel applied coatings in specific areas and spray applied coatings in other areas.

Over 40 years of accident free operations on APCI work.  Wow!  Always found Conomos to be dependable, trustworthy and highly-skilled.

What are the Challenges?

Concrete is:

  • Porous
  • Susceptible to Chemical attacks without coatings
  • Likely to Develop Cracks (due to movement and settlement of structure)
  • May be subject to Hydrostatic Pressure

Reasons to Coat Concrete

  • Coating of concrete surfaces is being required for protection from degradation of the concrete from the chemical composition of the fluids being contained or transported.
  • Some concrete is coated to make exposed concrete easier to clean, for example, graffiti on bridge substructures and superstructure components.
  • In addition, some concrete coating is used aesthetically or functionally to define aisle ways and specific safety zones.
