Wood glue for furniture is one of the main components that determine the quality of the product. perfect construction and joinery will not be complete without proper bonding, that’s why we pay very close attention to glue applications and base material.
There is wood glue for furniture we use in our furniture factory, each of them has its own loss and benefits depending on what furniture we are making. here are our short explanations of the wood glue we use for our furniture making.
Epoxy 2 Component Wood Glue
Epoxy 2 component wood glue is a mix of resin base and hardener components. From our experience, this glue is very strong and very hard when cured. it is so hard that will crack due to wood shrinking or swelling (wood movement caused by the weather), this is why this type of glue is not really suitable for outdoor use when the furniture will be facing extreme weather changes that can cause major wood movement.
On the other hand, epoxy glue can be very helpful in filling gaps in imperfect joinery, for example, hand chisel mortise tenon joint. Since we use hand tools to make these joints, occasionally we have too big holes for a small component. In this case, epoxy resin will do perfectly to fill those gaps and make a perfect bond.
Of course, we are talking about a few millimeter gaps. more than 2 millimeters then we have to throw away those components. too loose joints make a bad final result in overall construction. we do still use epoxy glue for our furniture but only in particular parts.
Polyurethane Glue
This type of glue expands and forms a foam shape when it’s cured. in our experience, they are weather reactance which follows wood movement due to weather changes. some high brands even make complete weather resistance with these materials.
This is our main reason to use them as Teak outdoor furniture applications. we also use this wood glue to make finger joint and dovetail joints since they can perfectly fill tiny gaps and penetrates deep into wooden pores, this will provide very strong bonding over the joints. But we don’t use this glue to butt joints or something similar to those types of joints since they are not very hard and strong without fit and snug joinery.
PVA Wood Glue
PVA stands for polyvinyl acetate and is the glue that is used to stick papers and other materials such as wood and cement together. PVA glue is waterproof and makes an excellent sealant for surfaces. they are water-resistant and very good for both indoor and outdoor applications.
We use them as our main wood glue for furniture making in our factory considering their flexibility and durability of use. but even so, this type of glue is not really strong to apply on “butt joints” since they are not hard when cured.
Super Quick Dry Glue (Cyanoacrylate)
Super Glue is a strong, fast-acting adhesive that sticks to just about anything almost instantly, so it’s easy to accidentally stick together fingers or drip it onto clothes or surfaces. We use them to repair small cracks and other minor repair to our furniture. Only small tasks can be handled by this glue since it easily cracks to a quite amount of force.
Those are wood glues we use in our Indonesian furniture factory, the explanations are only based on what we know and experience in the field, so it might not be an accurate technical description of the glue. please have your comments and criticisms on the sections below.
