In Felix's Flooring, gluing down your wood flooring is one method of installation and it means that the floor planks have been secured to the subfloor using a bonding agent or adhesive. We use modern MS polymer adhesive which is much more long standing than previous old fashioned adhesive materials.
An even layer of glue/bonding agent is applied to the surface of the subfloor, and to the edges of each plank so they can be secured to one another, before being slotted into place.
Glued down engineered wood flooring is the most popular method of installation, and we always recommend this options because it’s the more stable option out of the two.
This means that there is no shifting under your feet as you walk across it; making the floor feel firmer underfoot and doesn’t make any (or at least very little) creaking noise.
Glued down wood flooring can also be used on all types of subfloor surfaces, no matter how uneven - unlike floating wood flooring - so if you know that this is an issue in your property, then it’s best to play it safe with and glue the planks down.
