Unlike other wood glues, CA glue bonds almost instantly at room temperatures, so it should be handled with care and precision. CA glue can be used to apply glue blocks, or short strips of wood designed for reinforcement, to the back of a fresh furniture joint for as long as they’re needed. Once cured, cyanoacrylate bonds are very hard and rigid, which is helpful if you only need to create a temporary bond-a couple of taps of a hammer or mallet will break it. Cyanoacrylate (CA) is a quick-drying acrylic resin-and another name for superglue. Still, remove any excess glue with mineral spirits. If you intend to stain the wood, polyurethane goes on more easily than PVA. It also doesn’t dry out sensitive wood fibers. Polyurethane is moisture activated, meaning it relies on the moisture in the air to set, so it bonds very well in humid conditions, unlike other wood glues. These wood glues excel when splicing boards together like connecting two lengths of crown molding.
Used for everything from paint to wood floor finishes, polyurethane is a primary ingredient in many wood glues. Polyurethane is a synthetic plastic resin that creates tight, lasting bonds. Know that PVA glues are basically permanent. Then allow air circulation (from an open window or a fan) to create a strong bond. If clamping is not possible, add pressure by hand for a few minutes. Be sure to wipe away any excess glue with a wet rag or sponge before it is dry.įor best results when using PVA glue, press the pieces of wood together with a clamp until the glue is dry. Staining the dried glue will result in a patchy look. Another drawback is that PVA does not accept wood stains very well. PVA will leave a residue, affecting your wood’s finish-especially oak. White varieties of PVA are designed for indoor use, while yellow varieties (also called “carpenter’s glue”) are formulated for outdoor use. This wood glue is nontoxic (except when ingested), water-soluble (thinned by stirring in small amounts of pure water), and ideal for a wide range of projects, especially for nonstructural wood-to-wood bonds. Polyvinyl Acetate (PVA) is a rubbery synthetic polymer that creates a flexible, permanent bond. Some may even affect a wood’s finish more than others. In addition to chemical makeup, these glues also differ in terms of bond durability, flexibility, toxicity, and waterproofness. With the exception of hide glue, which is made of animal collagen, most wood glues are synthetic polymers or resins that are stronger than wood. When shopping for adhesive, it’s hard not to notice that there isn’t just one type of wood glue-rather, there are five main varieties.

The glue bond is so strong that separating the two pieces of wood often leads to broken boards or shredded wood fibers.įrom furniture building, woodworking, and cabinetry making to creating outdoor projects, wood glue can be a critical part of a project.
The best wood glues create a chemical bond between two surfaces, soaking into the fibers of the wood. But, for a truly permanent, strong chemical bond, using the best wood glue is the way to go. The soft, porous surface makes it easy to join pieces with nails and screws. It’s also relatively easy to build with wood. With its unique grain patterns and natural tones, wood earns praise for being a beautiful building material.
