Glue Dots are gaining popularity as an adhesive because they’re easy to use, versatile, and cost-effective.

They are a great alternative to other kinds of adhesives as they are safer than hot glue, less messy than liquid glue, and do not leave a sticky residue when removed like double-sided tape.

However, you might be wondering whether they will remain as effective when they come in contact with water.

So, are glue dots waterproof? Glue dots are not waterproof. You need to make sure they are applied on a completely dry surface because moisture can interfere with their bonding ability. They might be able to withstand light contact after they’re applied, but they shouldn’t be completely submerged in water. It’s also recommended to store it in a dry location away from humidity.

What Are Glue Dots Made of?

glue dots types to answer are glue dots waterproof

Glue Dots are made from various synthetic ingredients and rubber-based adhesives.  They come in the form of double-sided, pressure-sensitive patches that will bond instantly and strongly to various kinds of surfaces.

They also contain varying degrees of oils which give them their removable properties. So, as the strength of the glue dots increases, the concentration of oils decreases, and removing them will become more difficult. 

These oils can cause discoloration on some of the surfaces the glue dots are applied on, So, it’s recommended to test the glue dots on a small area before to ensure there will be no damaging effects on the surface.

How Strong Are Glue Dots?

Glue dots come in a range of tack types which indicate the level of strength of the adhesive. Let’s take a look at these different tack levels:

  • Low Tack – This kind of glue dots is easily removable which makes it suitable for temporary fixes that don’t require strong adhesion such as credit cards to letterheads.
  • Medium Tack – This kind of glue is also removable but it has stronger adhesion which makes it more suitable for heavier items such as sticking CDs to magazines.
  • High Tack – This kind of glue dots is for semi-permanent fixes. It can create a strong bond between most kinds of surfaces.
  • Super High Tack –  This kind of glue dots is for permanent fixes. It creates the strongest bond out of all types of glue dots and it can be used on all kinds of surfaces.

The strength of the glue dots can also depend on the surface they’re applied on. So, it is recommended to test the glue dots on any surfaces to determine if you have the correct tack level you need.

What Can Glue Dots Be Applied On?

Glue Dots can bond with almost any kind of surface including metal, wood, glass, plastic, fabric, paper, drywall, wallpaper, cinder block, photos, cardboard, chipboard, poster board, acrylic, and stainless steel. You can also use glue dots on walls as discussed here.

However, keep in mind that they work more effectively when applied on a clean dry surface because some substances such as dust or moisture can interfere with the bonding ability.

You also need to keep in mind that the number of glue dots you need to apply will vary depending on the size of the object or surface you’re applying them on.

How to Apply Glue Dots?

Glue dots are usually applied manually.

If you’re applying them from a roll, you can place the glue dots against the surface you’re applying it, peel the liner away then press the dots firmly into place.

If you’re applying them from a sheet, you can tear at the perforations, peel the tabs apart, place the tab with the glue dot against the surface then press them firmly into place.

Glue dots can also be applied using a dispenser that will ensure that the application process is faster and that the glue dots are aligned properly.
