Frequently Asked Questions
1. What sizes are available for weldbond?
Weldbond is available in numerous sizes for various applications and project needs.
Bottles: 160 ml/5.4 us floz, 420 ml/14.2 us floz,, 3l/101 us floz tubes: 60 ml/2 floz.
2. Can I keep my weldbond bottle outside in the garage? Will it freeze?
Weldbond should be protected from the cold as it will freeze. Once frozen, 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.
3. What is the shelf life of weldbond?
Weldbond typically has a shelf life of 5 years. If the product is starting to solidify, it can be restored by adding just a little bit of water. We advise the consumer to give the container a good shake prior to every use.
4. Is weldbond non-toxic?
Weldbond has been tested to be non-toxic. Weldbond conforms to astm d4236.
5. Where can I find the weldbond msds?
You can request one at the official website.
6. Is weldbond tested on animals or created with any animal by-products?
Weldbond is not tested on animals and does not contain any animal by-products. This product is vegan friendly.
7. What does the ul/ ecologo stand for?
The ecologo certification program was aquired by ulenvironment, a division of ul (underwriters laboratories) in 2010.Ecologo certification is based on multiattribute, life cycle–based standards. 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.
8. 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 must be sealed with 1 part weldbond to 5 parts water. Porous surfaces can be determined by dropping a small amount of water on surface. If water is readily absorbed, surface is porous. If water beads on the surface, it is non-porous.
Note: the sealing mixture of 1 weldbond to 5 water should not be used where water alone would have an adverse effect, i.E. On water soluble fillers.
9. Are there any materials that weldbond can’t glue?
Some types of plastic, rubber and cast metals will not produce a bond with weldbond, specifically polyethylene, unbacked vinyl, p.V.C., teflon, polypropylene, vinyl to vinyl, cast iron, cast aluminum. Weldbond is not intended for marine applications. It is not recommended for use on exposed exterior surfaces. Garage interiors are acceptable.
Note: do not use when bonding containers designed for use with, or subject to, hot liquids.
10. 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 clothes while using weldbond, just in case!
11.How do I dissolve weldbond?
Weldbond can quickly be 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.
12. 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 to 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.
13. What kind of paint will seal weldbond
we recommend latex and acrylic paints for the best results.
14. 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.
15. Can weldbond be utilized on marine applications?
Weldbond is not intended for marine applications. It is not recommended for use on exposed exterior surfaces.
16. My weldbond project bond has not dried clear.
A. Why not?
Most like 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.
17. Does weldbond release any fumes?
Weldbond does not release any fumes no matter if it is in liquid or solid state.
18. 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.
19. 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. The sealing mixture of 5 parts water to 1 part concentrated weldbond dries in approximately 1 hour.
