Polyurethane glue is not your run of the mill glue. On the contrary, it is one of the strongest and most versatile glues on the market. Granite, marble, glass, Formica, concrete, brick, stone, fiberglass, porcelain, wood, plastic, leather and rubber are just some of the materials that you can quickly and easily repair with polyurethane glue. Moreover, polyurethane glue is waterproof, and can withstand extreme heat and cold so no need to worry about using it on dishes, or storing repaired items outside.
The adhesive type that contains polyurethane as its primary ingredient. The most prominent characteristic of this special glue is its strength. However, the feature that will impress you most is the flexible nature of the adhesive; in spite of being hard and robust, metal bonders containing polyurethane is highly flexible. It's not easy to get such a combination. Polyurethane based bonders are also popular due to their water-resistant properties. For projects that need a durable bond, your first choice should always be polyurethane glue.
Here's how to use polyurethane to repair common household and holiday items needing a quick fix.
*Make sure that the surfaces to be glued together are clean.
*Apply the glue to one of the materials. (Keep in mind that a little bit goes a long way, so apply in moderation.)
*Make the repair.
*Wipe away any excess glue with a rag.
*Clamp, prop up, or balance the item so that the previously broken pieces stay firmly attached. For small ornaments you may tie a string around the object, or rubber band it together.
*Wait at least one hour. The polyurethane bond should be stable within 60 minutes, but it is best to leave the object alone for 24 hours in order for the glue to fully dry.
There are many different types of glues all over the world and furniture constructed in Asia is often done using lower quality glues to reduce costs. It is generally accepted that a European PVA glues and European Polyurethane Glues, when used correctly, are the best for constructing Teak Garden Furniture and Memorial Benches. Standard lower grade epoxy resins used in Indonesia simply won't hold in the long run. All good retailers and manufacturers will have this information to hand so ask!
