When it comes to gluing transition strips, the best option is a construction adhesive. This type of glue is specifically designed for use in flooring applications and provides superior strength and durability. It also has excellent water resistance, making it ideal for areas that may be exposed to moisture or humidity. When applying the adhesive, make sure to follow the manufacturer's instructions carefully for optimal results. For added security, you can also nail down your transition strips with finishing nails after they have been glued into place.
