Prevent Pinholes – Tame That Displaced Air!
Another method is to first apply an initial coat to random surface areas, causing trapped air to vent out into the uncoated surface areas. A layer of industrial floor coatings is then applied, but the trapped air is now fewer than before, lessening pinhole formation.
Preventing trapped air from ever surfacing is also possible through the application of extremely thick and strong industrial floor coatings. The industrial floor coatings should be tightly-sealing, leaving trapped air underneath the coated surface, with no means of escape.

Avoid Pinholes with an Even Profile
A rougher profile causes more air to be trapped during industrial floor coatings application. The trapped air will seek an outlet in whichever direction when displaced by a film of industrial floor coatings, sometimes merging with other vapors coming from other parts of the coated surface. When the combined air is strong enough to break free to the surface, blister-like pinholes appear.
To solve this cause of pinholes, abrasive blasting should be performed during surface preparation, to smoothen the irregular surface. A more even surface will remove ridges or pockets where air can be trapped during industrial floor coatings application. Another solution is to soak the surface with water prior to actual coating, which displaces air early on, before they are trapped during coating.
Another solution involves applying an epoxy formulation to fortify the concrete surface prior to industrial floor coatings application, which displaces air by tightly sealing the concrete surface.

Pinholes are Formed in Warm Temperature
To eradicate pinholes during industrial floor coatings application, there is a need to identify how they are formed or what causes their appearance in painted surfaces. Knowing how they are formed leads to an effective solution in reducing the occurrence of pinholes in industrial floor coatings application.
One of the primary causes of pinholes is the degree of temperature in the location where the industrial floor coatings application takes place. Moisture found in minute quantities in the concrete surface turns into vapor when the room temperature is warm. The trapped air is forced out of the concrete crevasses, but with no outlet to release this trapped air, it is vented out through any weak areas of the industrial floor coatings, forming pinholes.
To avoid moisture from turning into trapped air, the solution is to simply avoid applying industrial floor coatings in warm conditions. The concrete surface has to be cooler. Heat will make water molecules active and lead to vaporization, catalyzing the formation of pinholes.

Pinholes Can Mar Your Concrete Floor Coatings
Pinholes, those unsightly blisters that can mar an otherwise smooth concrete surface, are evidence of natural forces in action. The entire length of a concrete slab is riddled with air pockets, voids or spaces. When a film of concrete coatings is applied on the concrete surface, air is trapped within these minute capillary vents. When warm temperature heats the concrete surface, trapped air rises to the surface and forcibly creates crater-like indentations or pinholes in the surface.
The liquid properties of industrial floor coatings can also form pinholes. When fluid coatings settle in the concrete surface pockets, the air that formerly occupies the same pocket is forced out into nearby areas. An accumulation of displaced air will eventually cause a mini-eruption, forming pinholes.
In order to minimize or remove the occurrence of pinholes in industrial floor coatings, the causes of pinhole formation should be identified, and the corresponding preventive solution or action should be undertaken.

Neat Tips in Choosing the Right Concrete Floor Coatings – Part 4
The previous blog talked about other concerns and priorities that should be considered when selecting the right concrete floor coatings for facility floors, such as cost and aesthetics. It also discussed the advantage of having a good working knowledge about paints, to be able to identify the best-fit paint for the project.
Below tips continue with the emphasis on familiarity with the coating process and the value of expert opinion, to determine the best concrete floor coatings to use:
7. Know the ins and outs of the coating application process
Facility managers should remember that whatever coatings application methodology used to setup the concrete floor coatings system can greatly affect future performance. A poorly-prepared surface, or a deviation from the manufacturer’s Material Data Sheet during mixing, application or curing, or even a slight misstep in the application process, can cascade any flaws into the next processes. The result of this is a concrete floor coatings failure. That is why the proper observance of the correct application methods should be maintained at all times during concrete floor coatings installation.
8. Seek the expert’s opinion
Inputs from professional coatings contractors are very valuable in deciding on what concrete floor coatings product to use for flooring projects. Their training and years of experience will come into play in the selection process, having worked with varied types of concrete floor coatings for a long time. Relying on their expert knowledge is still the surest way to a successful concrete floor coatings project.

Neat Tips in Choosing the Right Concrete Floor Coatings – Part 3
Careful surface preparation and evaluation of the location and function of concrete floorings were discussed in the previous blog and considered key factors in choosing the right concrete floor coatings for coating system maintenance.
Below are two more tips in coatings selection:
5. Identify more concerns and priorities
Ideally, high performance should be the main basis in the selection of concrete floor coatings. On top of these factors, however, are other considerations that can also influence the choice of coatings. Aesthetics is one of them. If the concrete flooring system is located in the front lobby, for example, visual attractiveness is an important concern, necessitating the use of decorative concrete floor coatings. Environmental concerns, on the other hand, are a major priority for safety-conscious facilities such as hospitals.
Most of the time, however, economics exert the greatest influence in the choice of the best concrete floor coatings to install, with decision-makers going for the coating product that help in cost reduction efforts.
6. Zero in on the best-fitted coatings
Concrete floor coatings products vary in performance features, but the selection process is easy if facility managers know their paint basics. Such as the difference between epoxies and urethanes, high-performing formulations, damage-resistant and protective products, and even which products have low-VOC emissions. This knowledge is very useful in identifying the best-fit product for the specific project.
The next blog will discuss familiarity with coating application processes and the value of expert’s experience in the coating selection.

Continued: Neat Tips in Choosing the Right Concrete Floor Coatings – Part 1
The previous blog talked about the importance of knowing the properties and vulnerabilities of concrete floorings, which can influence the choice of the most appropriate concrete floor coatings to apply during maintenance or repair work. Below are two more useful tips:
3. Get a clear assessment of the surface and repair damages, if any
Careful surface preparation affects the success of any coating system installation. Surface preparation begins with a thorough inspection of the surface to be coated, its existing condition and need for remediation, if any is needed.
For example, if the concrete flooring is dirty, cleanup should be conducted. If molds or signs of bacterial growth are evident, removing these contaminants should also be done. If cracks or physical alterations are observed, then it is best to repair these damages first before concrete floor coatings are applied.
The reason for the meticulous surface preparation and remediation is to increase, as best as possible, adhesion during coating application.
4. Take into account the location and usage of the floorings
The different locations and functions served by concrete floorings in the facility influence the choice of concrete floor coatings to apply. Areas containing toxic chemicals require the use of coatings resistant to chemical spills. Loading bays with heavy loads require thicker concrete floor coatings.
The next blog will discuss other priorities and concerns in the selection of best-fit coatings.

Neat Tips in Choosing the Right Concrete Floor Coatings – Part 1
1. Get a basic knowledge of concrete floorings properties
Facility managers should know the basic properties of concrete, at the very least, for them to understand how these properties can affect the choice of concrete floor coatings to use during repair and maintenance projects. Concrete, which is a mixture of cement, water and aggregate materials like sand or gravel is built with strength and flexibility, making it very suitable for a lot of construction projects. However, concrete also possess some vulnerable properties. Knowing these strengths and weaknesses of concrete gives insight into the performance of concrete floors, and the identification of the most appropriate concrete floor coatings to apply.
2. Be familiar with concrete floorings vulnerabilities
Concrete may be known for its strength, but it also features a porosity that performs poorly when subjected to constant heavy loads and impacts. Concrete floors can crack under heavy load and during material shrinkage. This behavior of concrete floors can significantly influence the selection of concrete floor coatings to use in maintenance projects.
The next blog will tackle some more practical tips in selecting concrete floor coatings, such as surface assessment, and why location and usage are important.

Generations of Underwater Epoxies
1. First generation epoxies are formulated with the consistency of bubble gum. They are kneaded and applied on the target area by sticking them in. These epoxy coatings are known to contain harmful substances and a short pot life. Many existing marine structures still use them until today, because owners prefer to replace instead of repair problematic surfaces.
2. Second generation coatings have improved adhesion, eliminating the bubble gum formulation and the stick-on application method. These epoxy coatings continue to have short pot lives and contain hazardous materials. When it comes to bonding with cathode-protected substrates, performance of these coatings is also very low.
3. Third generation underwater coatings can be stored longer, and have zero-VOC formulations that make them more environment-friendly. Epoxy coatings of this generation have also addressed the poor bonding characteristics with cathodic surfaces.
The breakthroughs in underwater epoxy coatings are slowly being appreciated by facility managers, with an eye in keeping repairs costs to a minimum. Instead of total replacement, on-site repairs using these marine epoxies are becoming a more attractive choice.

How Underwater Epoxies Work
When moisture seepage has occurred in the regions between the coating and the coated surface, they weaken the adhesive properties of the entire coating system, resulting to visible blisters and cracks and a gradual coating failure.
Underwater epoxy coatings are designed to specifically address this problem, acting to displace any quantity of water within the surface, sealing it completely. Underwater epoxy coatings have a characteristic imperviousness to water. The presence or absence of water does not affect their chemical composition at all, which is a special polyamines formulation that is not moisture-attractive.
To understand this better, it is worth considering that ordinary coatings breakdown when exposed to water, because to these paints water is a solvent that leads to thinning out of the paint mixture. Often, too, the reaction of water to one or more components of the paint mixture can interfere with the curing process, leading also to eventual coating failure.

Underwater Epoxy Coatings Applications
Aside from the cost savings, two-part underwater epoxy coatings are designed for high performance and longevity, perfect for repair and maintenance work in piers, swimming pools, containment tanks, and structures that are partially or completely submerged in water most of the time.
Another desirable thing about underwater epoxy coatings is the ease of application they offer to painting applicators. For painting contractors that specialize in underwater coating applications, these epoxy coatings can be handled conveniently during the entire painting process, making the job as easy as when done above ground.
Underwater epoxy coatings are not only solely used for submerged surfaces, they are also effective in surfaces that are often exposed to certain amounts of dampness and water saturation. Facilities such as loading docks, ships, boats, and sweating pipes, which are not water-inundated but tolerate certain amounts of moisture most of the time.
Other applications where underwater epoxy coatings are effective are facilities in high-humidity locations, where ordinary paints often fail because of the high moisture levels.

Unsinkable Underwater Epoxies
But with the growing advances in underwater epoxy coatings technology, that trend is gradually reversing. Underwater epoxy coatings are proving to be more cost-beneficial in the long run, with the capacity to eliminate costly replacement with on-site repairs and maintenance. Underwater epoxy coatings are now imbued with better performance and flexibility in the repairs and maintenance of submerged structures.
Gone are the days when underwater painting means sticking a bubble-gum-like substance to the affected surface. Underwater epoxies are now impervious to water and act effectively as sealers, and are easier to handle and apply. More and more marine painting projects are using underwater epoxies, achieving high-performance, durability and cost-savings all the same time.

Prolonging the Useful Life of Exterior Deck Coatings
When exterior deck coatings show signs of deterioration, such as cracking, peeling, or a foul odor or discoloration coming from minute fissures in the surface, then it is usually indicative that deck coatings failure is about to happen. Facility managers must initially conduct a visual inspection of the affected area. When the aid of a professional coatings contractor is enlisted, the contractor assesses the area more skillfully. The contractor conducts a thorough and accurate inspection of the condition of the deck coatings system and can identify an impending or ongoing deck coatings failure more quickly. Moreover, the contractor can recommend the most effective solution based on the assessment.
When repair and maintenance is inevitable, can the facility manager hesitate or shelve this activity to some other time? The answer is commonly no, but when resources or funding is low, the activity can be waived, but only if the affected surface is not critical to the function of the facility. The facility manager must decide if the facility can take the risk of a degraded deck coatings performance, should the repair be put off to another time. Repair is often less costly than an overhaul of the entire coatings system.
