Using Mod Podge to seal alcohol inks on ceramic tiles

Sealing alcohol ink on ceramic tiles can be a tricky process, and Mod Podge offers a range of products that can be used for this purpose. Here is a guide on using Mod Podge to seal alcohol inks on ceramic tiles:

Mod Podge Sealant Options:

Mod Podge offers various sealants that can be used on ceramic tiles, including the Dishwasher-Safe Sealant, Spray Acrylic Sealer, Super Hi-Shine Clear Acrylic Sealer, and the Dishwasher Safe Gloss. The choice of sealant depends on the intended use of the tile. If the tile will be used as a coaster or come into contact with food, a dishwasher-safe option is recommended.

Application Techniques:

When applying Mod Podge to ceramic tiles, it is important to apply thin, light coats. This is because Mod Podge tends to leave visible brush strokes, especially if the coats are applied too heavily. To minimise brush strokes, some users recommend applying one coat in one direction and the next coat in the opposite direction. Additionally, avoid stacking the tiles after sealing, as this can cause the Mod Podge and paint to stick and pull off.

Curing and Drying:

Mod Podge sealants typically require a long curing time. The Dishwasher-Safe Sealant, for example, can take about 30 days to cure fully. During the curing process, it is important to keep the tiles away from humidity, as Mod Podge can become tacky and sticky if exposed to moisture.

Combining with Other Products:

To enhance the sealing effect, some users recommend combining Mod Podge with other products. One popular combination is using Kamar Varnish as the initial sealant, followed by Mod Podge over the top. The Kamar Varnish helps to fix the ink and prevent it from reactivating, while the Mod Podge adds a protective layer. However, it is important to note that even with this combination, the tiles may not be completely heat-proof or scratch-resistant.

Limitations and Considerations:

While Mod Podge can be effective for sealing alcohol inks on ceramic tiles, it has some limitations. Firstly, Mod Podge is not recommended as the sole sealant for items that will come into direct contact with food or beverages, as it may not be completely food-safe. Additionally, Mod Podge may not provide sufficient heat resistance for tiles that will be used as trivets or coasters for hot items. In such cases, a heat-resistant resin or enamel may be a more suitable option.

Sealing with resin

Sealing alcohol ink art on ceramic tiles with resin can be a great way to protect your artwork and ensure its longevity. Here are some detailed instructions and tips for sealing with resin:

Selecting the Right Resin

There are various types of resin available, such as Art Resin, epoxy resin, and bar top resin. Choose a resin that is suitable for your specific project. For example, if you plan to use the sealed tiles as coasters, consider using a food-safe epoxy resin that can withstand high temperatures. Check with resin companies to determine their products' dishwasher-safe requirements and maximum temperature resistance.

Surface Preparation

Before applying the resin, ensure that your ceramic tile is clean and free of any residue. Minerals or other substances on the tile's surface may repel the ink, causing it to disappear. If necessary, clean the tile and bake it in the oven at a low temperature to remove any impurities. If you have used silicone oil in your artwork, remove it with cornstarch before applying the resin.

Application Techniques

When applying resin, elevate the tile and pour the resin onto it, allowing it to drip over the sides. Wipe away any excess drips from the bottom of the tile. Alternatively, you can tape duct tape along the bottom sides of the tile and remove it once the resin has dried, taking the drips along with it. Protect your artwork from dust and insects by covering it while it dries.

Dealing with Bubbles

If you encounter bubbles in your resin, use a small torch or heat gun to remove them while the resin is still wet. Blowing on the resin with a straw when it is wet can also help eliminate bubbles.

Curing and Durability

Resin typically requires time to cure and harden completely. Follow the manufacturer's instructions for curing times. Once cured, your artwork will be durable and long-lasting. However, avoid using harsh cleaners on resin-sealed tiles, as they may cause scratching and discolouration. Instead, use gentle soaps and water for cleaning.

Additional Considerations

Resin can be combined with other sealants for added protection. For example, you can use a light coat of Kamar Varnish or UV protection spray before applying the resin. Always test your materials on a small area first to ensure they interact well with the alcohol ink.

Remember that resin can be expensive, so it may not be suitable for sealing multiple tiles or large surfaces. Always work in a well-ventilated area when using resin, as some products can produce toxic fumes.

Using Krylon Clear Polyurethane spray

Sealing alcohol ink art on ceramic tiles is important to protect the artwork from fading and breaking down over time through evaporation and exposure to ultraviolet light. Krylon Clear Polyurethane spray can be used for this purpose.

First, ensure that you are wearing the proper safety gear. Then, hold the spray can about 12 inches away from the tile and spray in a light, continuous, and even motion until the tile is covered. Allow the first coat to dry for about 1-2 hours. Apply a second coat of Krylon Clear Polyurethane spray using the same technique, and let it dry for about 1-2 hours as well.

If you desire a glossy finish, you can finish with a gloss medium such as the Krylon Triple-Thick Clear Glaze. Apply the gloss medium in the same manner as the previous coats, maintaining a distance of about 12 inches from the tile and spraying in a light, continuous, and even motion. Allow the final layer to dry for about 1-2 hours.

It is important to note that the number of coats and drying times may vary depending on the specific product and your desired level of protection. Always refer to the manufacturer's instructions for detailed application guidelines. Additionally, ensure that your artwork is completely dry and cured before applying any finish.

It is worth mentioning that some users have reported issues with chipping and flaking when using Krylon products, especially on tiles that will be handled frequently. To address this, some artists recommend using Krylon Kamar Varnish as a base coat before applying the Krylon Clear Polyurethane spray. This can help improve the adhesion and durability of the sealant.

Sealing with Kamar Varnish

Sealing alcohol ink on ceramic tiles with Kamar Varnish is a popular method, but it requires a few steps and considerations. Firstly, it is important to note that while Krylon Kamar Varnish is commonly recommended, the manufacturer does not endorse its use with alcohol inks. This is because Kamar Varnish contains mineral spirits and is not water-based, which contradicts the general advice that a water-based varnish should be used.

Despite this, many artists have successfully used Kamar Varnish to seal their alcohol ink creations. The process typically involves applying a couple of light coats of Kamar Varnish and allowing each coat to dry thoroughly. It is crucial to ensure that the alcohol ink is completely dry before applying the Kamar Varnish, as any moisture can cause the ink to smear or flake off. Leaving the ink to dry for at least 24 hours is recommended, and some artists suggest baking the ceramic tile in a low-heat oven to ensure thorough drying.

After applying Kamar Varnish, it is essential to let it cure for at least 72 hours. This curing process is critical in ensuring that the varnish properly seals and fixes the ink, preventing any smudging or flaking. Once cured, some artists choose to add an additional protective coat, such as Mod Podge, UV protection, or resin, on top of the Kamar Varnish.

However, it is important to note that using Mod Podge as a final coat can cause issues with stickiness, especially in humid environments. Therefore, if a glossy finish is desired, some artists opt for a different type of gloss sealer or varnish as the final coat.

While Kamar Varnish is a popular choice, it may not be readily available in certain regions, such as Europe. In such cases, alternatives such as Golden Archival Varnish have been suggested by artists, although the heat resistance of these alternatives may vary.

In summary, sealing alcohol ink on ceramic tiles with Kamar Varnish involves allowing the ink to dry, applying light coats of Kamar Varnish, curing for at least 72 hours, and optionally adding a final protective coat. While effective for many artists, it is important to be cautious of the manufacturer's recommendations and the potential challenges of finding stockists in certain regions.

Using Art Resin

Sealing alcohol ink art on ceramic tiles using ArtResin is a popular choice among artists. ArtResin is a self-levelling resin that can be spread around with a popsicle stick. It is available at Blick and Amazon.

Before applying ArtResin, the alcohol ink must be fully dry for 24-48 hours. The ink should then be coated to prevent it from interacting with the resin. It is also important to protect the ink from UV rays to prevent fading.

When applying ArtResin, it is important to elevate the tile so that the resin can drip over the sides. Any drips can be wiped off the bottom of the tile with duct tape. It is also recommended to cover the work with a large box to prevent dust or flying insects from sticking to it.

ArtResin is a durable sealant that can protect alcohol ink art from scratches and damage. However, it has a maximum heat threshold and is not food-safe. Therefore, it is important to consider the intended use of the ceramic tile before choosing a sealant.
