Woodworking is never an easy task, but its unique pleasure always appeals to a great number of people. And of course, if you are taking part in this kind of “art”, wood glue will be familiar with you. Currently, there is plenty of wood glues in the market, if you are wavering on choosing the most suitable type of glue and wonder how long for wood glue to dry, please read our article to clear up all your queries, and I bet you’ll choose the wood glue that fits your demand.
How long for wood glue to dry
Before answering the question “How long does it take for wood glue to dry”, let take few minutes to go through several popular and trusted types of wood glue in the market.
PVA Glue or Polyvinyl acetate is considered as the most well – known type of glue in the market. It is so popular and common that if you see a bottle of glue, it is likely to be PVA glue. Normally, PVA glue is used to join pieces of wood, adhere wallpaper, envelope or crafts. People usually make use of PVA glue because it possesses outstanding features. For example, it dries clear, doesn’t leave over nasty fumes, doesn’t break down and isn’t toxic unless you eat it.
There are 3 types of PVA: PVA – Polyvinyl Acetate (mostly used for box sealing and bookbinding and in pain), PVA Wood Glue (used for joining wood) and PVA Water Resistant Glue. From my own experience and observation, wood PVA glue takes approximately an hour to dry; you could heat into the joint to shorten the drying time. Also, PVA glue works most effectively in air-conditioned rooms and when it is compressed with some types of pressure.
Epoxy is made up of a resin and a hardener (both are liquid). When they are mixed, there is a chemical reaction happened which creates epoxy to harden. What makes epoxy special is that it is waterproof and able to fill gaps in the wood.
Unlike other wood glue, Epoxy could hold well even though there is a gap between two pieces of wood when you are gluing them together. In normal condition, epoxy takes a while to cure. But don’t worry if your epoxy takes longer to cure as the longer it takes, the stronger the bond is, hence all patients will be paid off.
Cyanoacrylate Glue is a fast – acting adhesive used in household and medical industries. Thanks to the capability of curing in a short period of time and enduring under impact, woodworkers use to make use of this glue in urgent situations. Furthermore, they will apply an accelerant to fasten the drying process.
CA glue can be used as a temporary step when joining pieces of wood together. Gorilla Glue is my favorite wood glue as it is high – quality and affordable, hence I made a gorilla wood glue review post on my blog.
Polyurethane Glue is activated by swells and moisture. Because it dries quickly (several minutes) and solidly, and is waterproof, hence, it is in the favorite glue list of woodworkers. However, everything has its pros and cons, and polyurethane glue’s downside is its high price.
There are several factors that you should put them into your consideration when choosing the appropriate type of glue: how long you work with glue, whether you need to fill a gap and whether you need glue to be water – resistant.
Hide glue is also known as the oldest adhesives on our planet as it was invented centuries ago. Nowadays, despite the significant development of high – tech glues, hide glue has remained its position in woodworkers’ heart and stood the severe test of the time. This glue is a protein-based glue which is created by melting down animal hides.
Especially, it is workable when its temperature reaches 140 – 145F and adhesive when it cools down and becomes solid. It will take about 24 hours to dry and hold a joint tight. What is more, there is another version of hiding glue so-called liquid hide glue which is usually used as PVA glue. However, if you are implementing a project which needs to be waterproof, liquid hide glue is not a smart option.
Several tips to speed up wood glue
Use New Glue
It is undeniable that the age of the glue affects vastly the overall performance of the glue, especially its dry time. The fresher the glue bottle is, the quicker the glue dries. As a result, make sure to use new glue for the sake of time – saving and quality.
If your project is left in an air-conditioned room or a well – ventilated space, the glue will dry faster thanks to the air flow. So if the moist season is coming, you should make use of a dehumidifier to shorten the drying process.
Thick layers will slow down the drying process of the glue, so you should apply thin glue layers for the sake of having fast – drying wood glue. In addition, a warm climate will help dry the glue faster because of the ability of warm air in absorbing water. You could make use of a hairdryer with low level to speed up the wood glue.
Do not dilute
Pouring water down the glue to make it dry faster is a common mistake that a lot of amateur or newbie woodworkers encounter. But the glue doesn’t work that way. Conversely, the diluted glue will ruin the adhesive bond between two pieces of wood.
Last but not least, clamping everything together to make sure the wood glue sets appropriately and the pieces are in the proper spot.
Hardwoods vs Softwoods
The glue drying time varies on hardwoods and softwoods. In fact, the structure and makeup of hardwoods are heavier and more complicated than softwoods. In specific, hardwoods have vessel elements for transporting water throughout the wood while softwoods use medullary rays and tracheids to transport water. As a result, hardwoods take longer to dry than softwoods.
A lot of people ask me that “Is poplar a hardwood”, in this article, I’ll make it clear. Regarding science, poplar is a hardwood tree that generates softwood compared to other hardwood trees.
