Construction adhesive is the go-to product for bonding materials that are also mechanically fastened. It dramatically reduces squeaks in subfloors and increases overall assembly stiffness.
Frequently Asked Questions
Can construction adhesive replace nails or screws?
In most cases it supplements mechanical fasteners. For subfloors, adhesive plus screws eliminates squeaks. Codes still require mechanical fasteners for structural connections.
