What Do You Seal Ceramic With?

Ceramic is a popular and versatile material used for a wide variety of applications, including home decor, dinnerware, jewelry, and even tiles and pottery. When it comes to sealing ceramic, there are a few different options depending on the purpose of the ceramic. Some seals offer protection, while others enhance the color and shine of the ceramic. In this article, we will discuss some of the different types of sealers available for ceramic and their unique features.

1. Glaze

Glaze is a common way to seal ceramics. Glazing a ceramic means to apply a thin layer of glass onto the surface of the ceramic object. This glass layer protects the ceramic from scratches, chips, and other forms of damage. Additionally, glazing can enhance the appearance of a ceramic by adding color, texture, and shine. Glazes are available in a wide variety of colors and finishes, including glossy, matte, and semi-glossy. Some glazes require multiple firings in a kiln to fully effectuate the seal. While glazes can be expensive and time-consuming to apply, the results can be stunning.

2. Wax

Wax is another popular way to seal ceramics. Wax can be applied as a liquid or as a solid and offers a quick and easy solution to protecting your ceramics. It can be applied to both unglazed and glazed ceramics, serving as an extra layer of protection from scratches, water, and other sources of damage. Wax also enhances the color and shine of a ceramic object. Some waxes are made specifically for use on ceramics, so it is important to choose the right one. Wax might need to be reapplied periodically to maintain its effectiveness.

3. Polymer Sealant

Polymer sealants are a versatile and popular option for sealing ceramics. They can be used on both glazed and unglazed ceramics and offer a strong, long-lasting seal. Polymer sealants offer protection against water, scratches, and other sources of damage, as well as helping to enhance the color and shine of a ceramic object. Many polymer sealants are also formulated to resist UV rays, which can cause fading on unsealed ceramics. They are often easy to apply, usually only requiring a single coat, and can dry quickly. This makes them a great choice for ceramics that are frequently used or handled.

4. Epoxy Resin

Epoxy resin is a two-part compound that is often used to seal and protect ceramics. Epoxy resin offers an extremely strong and durable seal, making it ideal for ceramics that will be subjected to heavy use or wear. It can also be used on glazed and unglazed ceramics, and it provides a crystal-clear finish that enhances the color and details of the ceramic. Epoxy resin cures to a hard, glass-like consistency, and it is highly resistant to water, scratches, and other types of damage. The most significant disadvantage of using an epoxy resin is the time-consuming application process that requires highly specific steps to ensure that the seal is successful.

5. Sealant Sprays

Finally, sealant sprays are another quick and easy option for sealing ceramics. These sprays can be generally used on both glazed and unglazed ceramics, they dry quickly, and serve as a versatile form of protection. Many sealant sprays are formulated to offer a range of additional benefits, such as UV protection and water resistance. They can be found in glossy and matte finishes to suit different preferences, and they are easy to apply. While sealant sprays can be an attractive option due to ease of use, they typically provide a less durable seal compared to other types of sealant options and the longevity of the seal tends to vary depending on the altitude and whether it's indoor or outdoor.

Regardless of the type of sealant used, preparing the ceramic to be sealed is vital and the process shouldn't be rushed. It is also worth noting that each sealant comes with unique aspects that make them more or less desirable for certain applications. It's important to keep in mind the intended use of the ceramic and the environment in which it will be used when selecting a sealant. From waxes to polymer sealants to epoxy resin and many more, there are plenty of options to choose from when it comes to sealing your cherished ceramic pieces.
