Choosing drywall adhesive is a bit different from choosing other adhesives, because bonding strength usually is not much of a concern when compared to other factors. Drywall often is applied to many different materials, including wood and metal, and the drywall adhesive should be able to bond to both of these materials. If moisture gets behind the drywall, then it can cause the adhesive to weaken and the drywall may fall, so moisture protection often is important. A unique property of this adhesive is that it can reduce sound; if this is required, then it may be good to check the exact amount of sound being blocked. Choosing an adhesive variety suited for an interior, exterior or both will ensure it works well for your use.
When you are setting up drywall, you have to apply it to another material, commonly wood, metal, more drywall or foam board. These materials are notorious for having poor bonding strength with most adhesives, so it normally is important to get drywall adhesive that will bond either to many materials or to the exact one you need. If you do not do this, then there is a good chance that the drywall will not adhere to the material to begin with or fall off in the near future.
Moisture can be a major problem if it gets into or behind drywall. This has the potential to loosen the drywall adhesive or to cause it to grow mold that either will be a simple annoyance or a legitimate health concern, especially in those allergic to mold. This means it often is a good idea to choose drywall glue that is moisture-proof.
Unlike nails, drywall adhesive has the ability to cancel out sound. If this is required or preferred, then it may be a good idea to see how much sound the adhesive is able to block. Some adhesives only block an almost imperceptible amount of sound, while other adhesives can be more silence-inducing.
Like many other adhesives, drywall adhesive comes in interior and exterior varieties, as well as varieties suited for either use. This will determine how the adhesive can be used and whether the adhesive is good against weathering. Choosing the wrong version can ruin the entire drywall project, so you should pick adhesive that works with how the drywall will be installed. Failing to do this can cause the drywall to fall from its place or for other problems to arise.
