This article is from Issue 52 of Woodcraft Magazine. Unless your woodworking projects are limited to knockdown furniture and timber-frame barns, you are already quite familiar with a variety of tubes, bottles, bags and jugs of this sticky stuff.

Pot life: The maximum amount of time you have to apply two-component glues to your work after they have been mixed. Open time: The maximum amount of time glued pieces can be left open to the air before assembly. Clamp time: The minimum amount of time required before you can remove the clamps from a glue-up assembly. If a joint is under stress, maintain clamping pressure for the full cure time.

Shelf life: The period of time that glue remains useable. Under ideal conditions, adhesives remain useable for longer time periods. If a glue appears abnormal, test first, or toss it in the trash. Under the ideal situations, all woodworking glues are capable of creating bonds stronger than the wood. In some cases, several glues can fit the bill. In smaller projects, creep means visible glue lines and laminations that lose their shape.

In larger structures, creep can spell joint failure. Avoid: White glue. It creeps the most, but most PVAs can stretch under long-term loads. Try: Urea formaldehyde and epoxy are the safest choices, but polyurethane is more convenient, and suitable for non-structural projects.

CA glue bonds are stiff to the point of brittle; the bond can be best ca glue for woodworking pdf with a hard rap. Gloves, respirators, goggles, and good ventilation provide decent defense, but if you are concerned about the effects of long-term exposure, or if you are chemically sensitive, steer clear of adhesives containing problematic chemicals, including those requiring solvent-based cleaners.

Avoid: Urea formaldehyde. It contains formaldehyde, a skin and lung irritant, and possible carcinogen. Polyurethane and epoxies contain sensitizers that can trigger allergic reactions.

CA fumes irritate eyes, nose, and lungs. Try: PVAs. These are nontoxic and clean up with water. Hide glue is made from skins and hooves. Open time, working time, and curing time all relate to how long it will take to glue up a project from application to maximum bonding. Depending on the project, speed can be best ca glue for woodworking pdf ally or enemy. Fast: Hot hide glue tacks best ca glue for woodworking pdf minutes, but with the aid of an accelerator, CAs bond instantly.

If you can afford a few minutes, fast-curing epoxies cure in minutes, but offer considerable strength. Slow: Titebond III and liquid hide glue offer more time for complex or multi-stage glue-ups.

For even more time, try Titebond Extend see sidebar, right. Polyurethane allows a comfortable working time for complicated glue-ups, but keep the clamps on until final cure or the foam can cause joints to open. Lowering the temperature will also buy more time. Woodworking in poorly heated spaces during winter months often leads to glue failure.

Avoid: PVAs. Try: Epoxies. In chilly conditions, you can use a heat lamp or hair dryer to help the epoxy kick in. Type II testing involves three soaking cycles and three drying cycles before the samples are tested. Despite type-ratings, all PVAs will soften in a constant marine environment. Avoid: White and hide glues. Their bonds can be undone with hot water. This can be an advantage when expecting repairs. Conservators prefer hide glue because new glue reactivates old.

Try: Epoxy is the only adhesive suited for constant water contact but for typical outdoor projects, Titebond II, polyurethane, and urea formaldehyde will all hold their own. For projects that might be exposed to hot water, consider Titebond III. If a joint is slightly less than perfect, you may not need to worry.

In such cases, consider leaving the clamps on through full curing to keep mating best ca glue for woodworking pdf as snug as possible. Bad craftsmanship and poor clamping best ca glue for woodworking pdf are another story. If you have a bridle joint with visible gaps, or a tenon that slides around within its mortise, you need a gap-filling specialist. Avoid: Polyurethane glue.

It foams as it cures, but the dry froth has no significant strength. PVA might also seem like a quick fix, but that gap-filling puddle will shrink as it dries. In both cases, the adhesives create a film that seals the cell walls, complicating a future fix. PVAs work if you can pack the joint to establish direct wood-to-wood contact.

Try: Epoxy is the best choice for structural, gap-filling repairs. You can build epoxy fillets around joints for additional reinforcement. Special-blend PVAs possess certain abilities that have made them shop favorites.

With a minute open time twice as long as regular TitebondTitebond Extend is useful in complex glue-ups. For cabinetry, try Titebond Melamine. As the name suggests, this PVA sticks to melamine, and also vinyl, high pressure laminates and wood. Titebond No-Run, No-Drip stays put and grabs quickly, making it perfect when installing molding and trim.
