Can I keep my Weldbond® bottle outside in the garage? Will it freeze?

We’ll break down the answer for you: Yes, you can keep it in your garage, your bedroom, a closet, your shrine to a TV celebrity from the 80’s. No, you cannot keep it in any of these places if they are prone to freezing. Weldbond® should be protected from the cold as it WILL freeze. Once frozen, and then thawed, this product loses all adhesive capabilities. It should be stored above 50°f/ 10°c at all times. Also, after the container has been opened, ensure it is closed tightly after each use.

All products certified to an Ecologo standard must meet or exceed each of the listed criteria before receiving the mark.Product certified for reduced environmental impact. View specific attributes evaluated: UL2762.

What is meant by porous and non-porous surfaces? How can I tell which is which?

A porous surface means that the material is full of tiny holes that allow fluids or gases to pass through, non-porous surfaces do not allow anything to pass through. Porous surfaces can be determined by dropping a small amount of water on surface. If water is readily absorbed, the surface is porous. If water beads on the surface, it is non- porous.

Are there any materials that Weldbond® can’t glue?

Note: Do not use when bonding containers designed for use with, or subject to, hot liquids.

How do I remove Weldbond® from my clothes, carpet, curtains or anything else?

Weldbond® is a water-based glue therefore if the stain/spill is recent we recommend using cold water, not hot water. However, once the glue has set it is very difficult to remove therefore be sure not to wear your favourite tie-dye shirt or bell bottom jeans while using Weldbond®, just in case!

How do I dissolve Weldbond®?

Weldbond® can be quickly dissolved with acetone. Because Weldbond® is water based it can also be dissolved with a soaking of, or submersion in water. This will dissolve a bond.

Can Weldbond® be tinted?

We have many craft users that tint Weldbond® with a wide variety of creative methods, including tea, paint, nail polish and other creative methods. We always recommend the consumer test this creation on a small piece prior to proceeding with the full project. Some compounds utilized for tinting could have an adverse impact on the makeup of the Weldbond®.

What kind of paint will seal Weldbond®?

We recommend latex and acrylic paints for the best results.

Can Weldbond® be utilized on external applications?

Weldbond® can be used on external applications as it is weatherproof. However, Weldbond® is not WATERPROOF, it is water resistant. Weldbond® should only be used on external applications if it is free of standing water that could cause it to freeze or if it is being used on a vertical surface where water cannot pool on top.

Can Weldbond® be utilised on marine applications?

My Weldbond® project bond has not dried clear.

A) Why not?

Most likely too much adhesive was used. Another possibility could be that if you are gluing a large surface, air cannot get to the Weldbond® in the middle of the bond. We do suggest that if you are gluing large pieces, you apply the adhesive to the exterior rim and not the centre as a proper bond might not take place.

B) What can I do about it?

Apply heat. If weather conditions permit, set the project in the sun. For large glass surfaces, glue the edges, but stay away from large amounts of glue through the middle of the surface. Weldbond® air cures.

Does Weldbond® release any fumes?

Weldbond® does not release any fumes no matter if it is in liquid or solid state.

What is the set-up time?

The set-up time for tackiness will vary with humidity but is roughly five minutes for most projects. It will be somewhat longer in humid conditions.

What is the cure time?

Weldbond® becomes tacky quickly and will dry within the hour on porous surfaces. Provides a strong bond within 24 hours and tremendous strength within a few days.
