Benefits Of Primer In Industrial/Commercial Painting And Flooring

The Benefits of Using a Primer with Epoxy Flooring or Industrial/Commercial Painting

If you want to obtain a very professional and classy look for your place while painting the exterior siding or the interior walls, make sure you apply a coat of primer first! Primer is supposed to serve three major functionalities:

  1. It obstructs stains as well as resinous knots from bleeding through;
  2. It offers single-coat coverage for the paint topcoat
  3. It improves adhesion and reduces blisters, extending the life of the topcoat.

These benefits make primers a great addition with epoxy flooring, industrial painting or commercial painting.

Primer with Epoxy Flooring– Applying epoxy floor coating is one of the most sought out methods that are being utilized for improving the life of the garage flooring or of your home. Mostly epoxy flooring is used along with primer for a high durability as well as robustness. Flooring gets damaged due to various chemicals and other stuff, so to avoid this damage and devoid the floor’s natural beauty primer is used with epoxy flooring. Epoxy is considered as one of the best options, because of its water resistant, easy to apply, easy to paint and well bonding features. When used with primer, it becomes more shinny and evenly easy to clean as well as maintain. Other benefits are minimal repairs, lasts longer, nominal renovation and quiet durable.

The Benefits of Applying Concrete Sealer

Concrete Sealers

Concrete sealers improve the durability, stain-resistance and appearance of concrete floors, structures and driveways. Sealers are either of the penetrating or film type:

  1. Penetrating sealers react chemically to penetrate the concretes pours and protect the concrete against water, ice and de-icing chemicals. They act invisibly to protect exterior concrete from freeze-thaw damage and from corrosion. The better products allow water vapor to escape the concrete. Penetrating sealers often contain compounds such as:
    1. Silane a small inorganic compound of formula SiH4 that clots concrete pores via covalent bonds. Silane resists water and oily stains, has low viscosity and is often used to seal dense concrete that has fully cured.
    2. Silicates — an oxide containing silicon and a cation such as lithium or sodium. In contact with concrete, silicates form calcium silicon hydrate, which adds density and can be polished to a high sheen.
    3. Siliconates — compounds such as K4SiO4 (potassium methyl siliconate) are extremely hydrophobic and protect concrete from freeze-thaw water damage.
    4. Siloxanes — large molecules in which an oxygen atom attaches to two silicon atoms. Siloxane-based sealers are useful for protecting exterior concrete and porous concrete block.
    Acrylic resins form a protective film on concrete in both interior and exterior applications. These can be water- or solvent-based. They quickly dry to various glosses and enhance the beauty of stamped, colored or decorated concrete. They provide good protection against water and salts, but require regular maintenance with a floor wax or finish. Polyurethanes build a thick protective film that helps protect high-traffic areas. They resist wear, chemicals, scuffs and stains while imparting a matte or gloss look. The finish won’t yellow and is transparent. Care must be taken to protect polyurethanes from water until they finish curing. Epoxies are usually two-component mixtures. They form a tough, thick glossy film that is often used to seal concrete countertops as well as high-traffic floors. Epoxies are available in colors, but clear epoxy applied outdoors tends to yellow over time. High water resistance can trap water vapor in the concrete.

    Usage Tips

    Questions often come up as to which sealer to use for particular applications. Here are some helpful tips:

    • If you want to protect decorative concrete work, look to a film-based sealer.
    • Always check product compatibility for the type of surface you want to seal: a floor overlay, stained concrete, polished and dyed floor, etc. Using an inappropriate sealer can result in bleeding, blistering or bubbling.
    • If you are most concerned about protecting an interior concrete floor from stains or scuffmarks, choose a sealer, such as polyurethane or epoxy, that creates a high-build protective film. These are especially good for high-traffic public locations, and they require less maintenance than acrylic sealers, which need periodic applications of wax or polish.
    • If you are concerned about inhaling volatile organic compounds in a poorly ventilated area, gravitate towards water-based sealers instead of solvent-based ones. In addition, be aware that solvent-based concrete sealers are flammable and may have noxious fumes.
    • Choose the sheen you want for the sealed floor. Those seeking a polished stone look should select a high- or medium-gloss sheen. Acrylic sealers give the widest ranges of sheens. If you don’t want a shiny surface, pick a sealer with a low-gloss or matte finish.
    • The life expectancy of a sealer depends on its type, its maintenance and the amount of exposure it receives. Urethanes and epoxies can last for years and then might need to be reapplied. Other types will require more maintenance and quicker renewal.

Concrete Joints : Installed by PennCoat

Expansion Joints installed by PennCoat

Joints Placed in Concrete Slabs

For such a thick and heavy surface, concrete always seems to be on the move. As newly poured concrete slabs dry, the loss of moisture causes the material to contract. Once dry, concrete will expand on hot humid days and contract on cold dry ones. For example, drying concrete will contract 2/3 of an inch per 100 linear feet. All this movement causes cracks. Actually, the problem isn’t the movement per se. The real culprit is the restraint of concrete’s movement by the underlying subgrade, footings, walls and adjoining slabs. The solution is to place control relief joints in the concrete to ‘”pre-crack” it at pleasing, controlled intervals or at the interfaces with other structures. When done properly, the relief joints will suppress random cracking, which tends to look unsightly.

Polished Concrete

Polished concrete flooring has become a popular option for commercial and industrial venues, especially ones that want to minimize maintenance. Polished concrete is extremely durable, can be buffed to various degrees of shininess and can be decorated in different colors and styles. Maintenance requires a daily dry dusting with a microfiber pad and weekly washing with water, perhaps mixed with some pH-neutral floor cleaner, and applied with soft pads. The surface need not be sealed or resealed as long as it is properly prepared and maintained.

  • Improve Longevity

Commercial painting offers a wide range of benefits for property and business owners. The improved appearance of an office or retail store can help attract more customers and clients. A well maintained property is much more welcoming than a property with chipping and peeling paint, and also creates a cleaner environment for your customers and potential clients. In addition to improving customer experience and confidence,  commercial painting can protect the surface of your building’s exterior. Constant exposure to sunlight and a number of  weather-caused damages can have effects on structural material. By coating the exterior with UV resistant and weather combatant paint, the longevity of the facility can improve due to commercial painting alone.

Understanding Tech Data Sheets: Impact Resistance

Impact Resistance

The impact resistance, or toughness, of a material is its ability to absorb energy without fracturing or rupturing, even if it plastically deforms. Technically, it is the integral of energy divided by volume, aka the stress-strain curve we’ve discussed in previous blogs. It is similar to resilience, except the upper limit of integration is unrestricted. There are several ways to measure impact resistance, including the Izod Impact Test:

and the Charpy impact tests:

But the materials we commonly use at PennCoat frequently undergo the Navy’s MIL-D-3134J Military Specification for Deck Covering Materials, which addresses materials used to cover shipboard interior decks in sanitary and other wet spaces. The Navy classification scheme is as follows:
