When properly selected and installed, construction adhesives applied to wood subfloor systems provide builders with solid flooring solutions. Problems, however, can surface in the form of squeaks, creaking, and other noises when improper installation and inadequate or incompatible materials are combined.
Subfloor related noises can often be attributed to movement of flooring components when walked on; a result of excessive gaps between flooring panels and the supporting joist system. Panels not held tight to supporting joist system components may move and rub against metal (i.e. nails) and/or compress and crush cured adhesive.
These gaps may form for a variety of reasons. Below is a noncomprehensive list of the most common. By understanding these causes, installers can avoid future issues by preventing gaps and subsequent noises, while ensuring the fastener and adhesive combination initiates and maintains a tight, reliable bond between the panel and joist system.
