Aggressive Floor Prep Work for Epoxy Coatings

removing epoxy coatings

Removing epoxy coatings from concrete is common practice in the epoxy flooring business.  But although common, it never easy, and can often be a big gamble when estimating time and material.

Epoxy coating removal is a necessary step when polishing concrete, or when a failed coating needs to be removed.  However, although saying “removing epoxy” is easy, the actual process is much more difficult.

The most important thing to look for when assessing a demo floor job, is how thick the existing coating is.  Epoxy thickness is measured in mils.  And the more mils of epoxy on the floors, the more difficult it will be to remove that epoxy.

But for reference, a 20-30 mils of epoxy is about as thick as a credit card.  So if you’re able to remove some coating during your site visit, compare it to your credit card to determine how thick the existing floor is.  But keep in mind that the floor temperature needs to be considered.  So when visiting potential job opportunities, be sure to bring your industrial infrared thermometer to gauge the temperature for the floor.

Choosing a paint for Equipment Painting

Painting equipment is one of the most common requests for industrial painters.  From finding the appropriate coating, to discovering the best prep method, to minimizing sensitive computer components.  There are a number of factors that need to be considered before embarking on an incredible painting journey into the angular movements of equipment painting.

In the world of big industry, there are innumerable operations that equipment can perform.  And sometimes that performance requires highly concentrated coolants and oils that can keep the machinery operating.  And other times, that equipment contains highly sensitive computer boards that need to be protected from excessive amounts of water.

But when an owner whats his old, dated pieces of equipment freshened up with a new coat of paint, it proves to be very challenging.

Firstly, as with any painting project, the prep method is going to require a lot of thought and consideration.  As mentioned, modern equipment can contain a lot of computers and electronics.  And if those electronics get wet, it can completely damage the entire piece.  However, sometimes that piece will be caked with old coolant or motor oil.  And if the surface is too saturated with oil, then the adhesion will be compromised.

The Versitility of Urethane Cement

Epoxy flooring contractors are finding that urethane cement is a practical and efficient primer and resurfacer in nearly every application.

Urethane cement was introduced into the market a few decades ago.  And whether is was installed in Pennsylvania, or applied by some flooring contractors in Maryland, it was widely accepted upon reception for a few reasons.  Firstly, the most commonly used flooring material prior to urethane cement was epoxy.  Epoxy is typically a decent floor.  However, it is susceptible to osmotic blistering, ambering, and vapor transmission.

But because urethane cement is able to not only bond extraordinarily well to the concrete, it has exceptional chemical resistance.  And this chemical resistance also allows it to hold up against the sodium from transmitting through the concrete.

Painting Fiberglass Cooling Tower for Industrial Facility

IMG_1841

Maryland Commercial and Industrial Painting projects don’t seem to have any limitations with difficulty.  And when we were contacted by a power facility to paint their fiberglass cooling towers, we knew the difficulty level wasn’t trying to decrease.

Fiberglass is a challenging substrate to paint.  Creating fiberglass requires a process called gel-coating.  This process involves soaking layers of fiber inside resinious material.  Collectively, these create a durable, smooth, waterproof, and very strong surface.  Here’s a video with more details:

The gel-coat creates a smooth, impervious surface.  This is great for aquatic equipment, such as boats, water-park equipment, or the top of a cooling tower.  However, the challenge presents itself when it comes time to paint that fiberglass.  And the challenge is that it’s usually not profiled enough for common coatings to bond properly to the substrate.
