Tumblers as gifts look boring if they’re plain. However, with adhesive vinyl decals customization, you can make them colorful, personal, and artistic. Moreover, the process of customization doesn’t end here. You need to protect the vinyl on your stainless steel tumbler from harsh elements, including wear and tear.

How? Through sealing the decor. Thus, in this article, learn how to perfectly seal vinyl with the best sealant to keep your decor from peeling away and last for years. But, let’s have a brief overview of the different types of adhesive vinyl used for tumblers, so you can see where sealants enter into the scene of crafting.

Outdoor Vinyl vs. Indoor Vinyl: Overview

These two are types of adhesive vinyl. Furthermore, removable vinyl is also called indoor vinyl and permanent vinyl is also called outdoor vinyl. As the name suggests, this vinyl is removable and is best used for crafts that don’t need washing or constant cleaning.

Outdoor adhesive vinyl is permanent and can last several years depending on wear and tear conditions. Often, this is the best vinyl for tumblers, stainless steel mugs and plastic cups. So, why do you need to seal them? Because daily handling of your tumblers can take a toll on your adhesive vinyl decals.

No matter how high the quality of your vinyl is, it might still peel away from your tumbler if you constantly use it and wash it with water. We know, it’s painful to see your craft be ruined when you can do something about it. So, this is where sealants come into the scene.

Importance Of Sealing Vinyl

Many crafters say vinyl doesn’t need sealing because most types of vinyl are waterproof or water-resistant. These types of permanent vinyl can last for years, which is true by the way. If you want to create more long-lasting vinyl mugs and tumblers, you might want to consider applying some sealant. Why decorating your tumbler shouldn’t end with vinyl and transfer tape?

Sealing your vinyl tumblers with a heavy-duty sealant is important for several reasons. First, it prevents the vinyl from peeling or cracking. Second, a sealant protects the vinyl from fading over time. Finally, sealing prevents condensation from forming on the outside of the cup.

Types Of Sealant

Sealants are clear coats that are applied over the vinyl decal to protect it from wear and tear and harsh elements such as the dishwasher. There are two main types of sealants: water-based and oil-based. Water-based sealants have a lower VOC (volatile organic compound) content. The VOC makes them more environmentally friendly.

They're also easier to clean up if you make a mistake while applying them. However, they may not be as durable as oil-based sealants. Oil-based sealants, on the other hand, provide a stronger barrier against moisture and wear. But because they're made with petroleum products, they're not as eco-friendly as water-based sealants.

Sealants For Every Crafter

Tumblers are incredibly versatile and you can use them for hot or cold beverages. Thus, you should consider the sealant to use. There are a few different options available, and each has its own pros and cons. Here are just a few of the sealants you may want to consider for your tumblers with vinyl:

Polycrylic

Polycrylic is a water-based versatile sealer that you can use for a variety of applications. It has two variants: spray form and liquid. When compared to other sealants, this sealant is relatively easy to apply. However, the biggest drawback is its application. You need to apply thin layers at a time. If you're looking for a thicker, more protective coating, allow the polycrylic to dry between layers.

Patience is key when working with this sealant. It's also important to choose polycrylic over polyurethane as polyurethane may cause damage if handled incorrectly. When used correctly, polyacrylic is an excellent option for sealing and protecting surfaces.

Mod Podge

This versatile and non-toxic product is easy to find in art and craft stores, whether in small bottles or larger quantities. To seal vinyl, simply apply a coat of mod podge over your vinyl decal using a brush, just like you would with paint. Mod Podge works great for adding a personalized touch to mugs, tumblers, plates, and other dishwares.

With its wide range of finishes, from matte to glossy to glitter, there's an option for every style and taste. One potential downside is the minimum curing time. You’ll need at least 28 days after it has been applied, so make sure you don't lose track of time.
