If you are working with non-porous surfaces, then Liquid Nails would be a better option than wood glue. It is also the better option if you are using the glue in situations where you can’t clamp materials. If you are pushed for time or gluing wood in fiddly spaces, opt for Liquid Nails. It has a far shorter drying time and will bond your pieces together quickly, without needing to be clamped. However, if you are trying to glue two pieces of wood together, it is better to opt for wood glue. As strong as Liquid Nails is, it isn’t as strong as wood glue, so it's better to use wood glue when gluing wood on wood. You will also want to take care when using Liquid Nails as it can be toxic. Be sure that you carefully follow the instructions on the label and take all the necessary safety precautions when using Liquid Nails and waiting for it to dry. When deciding between Liquid Nails and wood glue, consider carefully the materials you are using to help you decide which is best for you. Both are fine choices providing they are used in the appropriate settings.
