Wood Glue

Choose by application: PVA (white/yellow) for general woodworking and indoor joints, waterproof or aliphatic resin variants for exterior or high-moisture use, epoxy for gap-filling and structural bonds, and polyurethane for bonding dissimilar materials or where moisture cure is acceptable

Drying time varies: many PVA glues set in 20–30 minutes with full strength in 24 hours; epoxies and polyurethanes may take several hours to cure depending on formulation and temperature. Strength is typically described as wood-to-wood shear strength—most woodworking glues will produce joints stronger than the wood when clamped and cured properly

Surfaces should be clean, dry, and free of dust, oil, or old finish; rough-sawn or planed surfaces bond best. Apply an even coat, mate parts within the glue’s open time, and use clamps to maintain pressure until initial set—excess glue should be wiped away before it cures

Most wood glues can be sanded once fully cured; PVA dries to a slightly different color and may raise grain requiring light sanding before finishing. Test compatibility with your chosen finish—some waterproof glues and epoxies can resist stains or sealers differently than the wood

Use in a well-ventilated area, avoid skin and eye contact (wear gloves and eye protection if needed), and follow manufacturer instructions for ventilation and first aid. Store unopened containers in a cool, dry place; keep caps sealed to prevent water-based glues from skinning over and reactive adhesives from curing in the container

Prices range by type and size: basic PVA glues and small bottles are budget-friendly, while specialty epoxies, exterior-grade formulations, and professional-sized containers cost more; shoppers can expect options both under $50 and higher for larger or specialty packages
