There are two basic methods for gluing oak floors: the floating floor method and the glue down method.
Engineered oak flooring can be floated or glued down whereas a solid oak floor must never be floated (the boards simply aren't stable enough)
Installing An Oak Floating Floor
In essence, a floating floor is one where the floor boards are stuck together and simply lie on top of the subfloor without being attached to it.
This is a great option where the underlying moisture content of the subfloor is unknown as it allows for an uninterrupted damp proof membrane to be laid under the floating oak floor, protecting it from any rising dampness.
One of the problems of a floating floor is the potential for echoing when walking across the floor. This is caused by the 2 hard surfaces making contact and the sound reverberating through the space between them.
To prevent echoing, an underlay should be fitted over the damp proof membrane to absorb any sound transmission and indeed deaden the sound of footsteps on the floating floor.
1. Even out or level the subfloor where possible - the flatter it is, the less chance of creaking, echoing, etc.
2. Lay out a damp proof membrane in an uninterrupted sheet over the sub floor ensuring an overlap all round to run up the skirting boards or room edge.
3. Apply PVA glue to the upper and lower sides of the groove on each board before laying it, ensuring an even continuous bead on each side.
4. Push the tongue of the next board into the groove of the previous board
5. Repeat until the floor is laid.
6. Stay off the floor until all the joints have dried and then either wipe off or sand off any PVA residues on the floor.
7. Trim the damp proof membrane around the edges of the room and either fit skirting over it or apply a finishing strip to the skirting.
Gluing Down An Oak floor
This method can be used for engineered flooring or solid oak flooring and provided the subfloor is well prepared, provides for the best results.
1. Prepare the subfloor - this is crucial to the end result and the methods of preparation depend on the sub floor in question. Whichever type of subfloor, it should be level, solid, dry and dust free.
2. Apply a dedicated wood flooring adhesive such as ProFlex MS Polymer to an area which you can comfortably complete laying in 20 minutes.
3. Lay the floor boards in the usual way, but make sure to remove any adhesive from the top face of the boards as it is very difficult to remove once cured.
4. Allow the adhesive to cure for 12 or more hours before walking on the floor.
