What Is Enamel Paint?

The properties of enamel paint are more important than the substance. In its broadest definition, enamel paint refers to any solvent-based paint that dries to a hard, vitreous-like (or glass-like) shell. In contrast to water-based paints, solvent-based paints are sometimes known as oil-based paints.

Enamel paint is based on root words that mean smelting or melting. Actual enamel is a glass covering that is melted or kiln-baked onto metal or ceramics at extremely high temperatures.

On the other hand, enamel paint shows no resemblance to molten glass enamel since it contains no glass. Even traditional baked enamel treatments, which have long been employed on automobiles, have nothing to do with glass. Baking is just a quick way to eliminate solvents and VOCs.

In truth, air-dry enamel paints are significantly softer than kiln-formed enamels. Paint makers have broadened the concept by sometimes applying the term enamel to water-based paints, eliminating the one element that generally binds all enamel paints together: solvents.

Enamel Paint’s Origin

Like many other home-related items, enamel paint is a savvy marketing maneuver and a physical product.

In a period when paints were less than dependable, and whitewash paints were friable and prone to smudging, adding the term “enamel” to paint gave consumers much significance in the mid-1800s.

In the eyes of customers, enamel was linked with the vitreous shell surfaces of porcelain and ceramic tiles and porcelain bathroom fittings. These are goods that potential purchasers were familiar with—or at least were aware of.

Enamel goods were impermeable, hygienic, and extremely durable. Translating the concept of enamel cookware, tiling, sinks, and bathtubs to paint was an easy shortcut to indicating that this paint was also water-resistant and robust.

For industrial purposes, powder coating has essentially replaced baked enamel coating. However, the primary challenge for enamel paint came after World War II, when synthetic latex paints were launched. Enamel paint is still associated with hard-shelled products such as major appliances such as refrigerators and washing machines, but these, too, are now powder-coated.

Where to Use Enamel Paint

Brush, roll, or spray enamel paint for home projects that require either extreme durability or a glassy, glossy finish. See the list of popular uses for enamel paint below.

Restoring a Barbecue Grill

Clean the exterior surfaces of your BBQ grill thoroughly. Take out the grill rack. Coat the BBQ grill twice with heat-resistant enamel paint using spray paint in a can.

Door Casing Painting

The door casing takes much punishment. As a result, it makes sense to use long-lasting and easy-to-clean paint. Trisodium phosphate should be used to clean the door casing (TSP). Mask the area surrounding the casing on the wall with painter’s tape or self-sticking masking film. A drop cloth should be used to cover the floor. Put a minimum of two coats of enamel paint to the door casing with a high-quality brush.

Rejuvenate Your Outdoor Furniture

Even the most durable resin outdoor furniture can fade over time. A spray can of colorful enamel paint aids in bringing that furniture back to life. Use a low-pressure pressure washer or a water hose, a soft brush, and light detergent to clean the furniture. Let the furniture dry completely before applying two coats of enamel paint.

Kitchen Appliance Repair

Use tiny bottles of appliance enamel paint to repair chips and scratches on refrigerators and stovetops.

Precautions Before Using Enamel paint

VOCs (volatile organic compounds) are commonly found in enamel paint and can trigger mild to severe responses in certain persons.

Use high VOC paints only in well-ventilated locations. When working with enamel paint, it is strongly advised to wear a painter’s respirator.

How to Use Enamel Paint

Wash the Surface

It is critical to clean the surface to remove any dust and dirt that may have become trapped beneath. “High-gloss paints tend to showcase defects on a surface, so carefully preparing the surface before painting is critical for a successful paint job,” Sinclair adds. “To accomplish this, thoroughly clean the sections to be painted with a decent cleaner, degreaser, or emulsifying dish soap, then rinse with water and allow to dry.” Sand away any scuffs and other imperfections to create a paint-ready surface, then wipe away any sanding dust with a clean, damp rag.”

She underlines one critical point: “Removal of old paint by sanding, scraping, or other ways may generate dust or vapors containing lead.” “Lead dust or fumes can cause brain damage or other health problems, especially in youngsters and pregnant people. Controlling lead or other hazardous substance exposure necessitates the use of appropriate protective equipment, such as a properly fitted respirator, as well as effective containment and cleanup.” (Kokkori, M., Sutherland, K., Boon, J., Casadio, F. and Vermeulen, M., 2015)

Prime the Surface

When the surface is completely dry, apply primer with caution. This procedure is critical for materials prone to warping, such as wood, since it prevents paint chips. If you’re going to treat an outside surface, make sure to use an outdoor primer.

Mix the Paint

To ensure that all of the enamel paint’s components are evenly distributed, stir it with a stick long enough to reach the bottom of the can.

Apply the Paint

Once the primer has dried, it’s time to apply the enamel. Using a high-quality paintbrush with the paint is key since a cheap brush can create unsightly streaks and marks in the finish.
