Cork Underlayment Installation

A cork underlayment installation is much easier than the glue down tiles. The first thing is: you treat your underlay like you would treat the floor above it. If you are floating the floor, then you float the underlay. If you glue down your hardwood, then you glue down the cork underlayment. Our cork underlay accepts any water based construction adhesive. A trowel-on application works wonders because there is very little concern if the cork “curls” when exposed to the adhesive. It works well if you allow the troweled adhesive to set-up a little before laying the cork underlay. This allows the liquid in the adhesive time to evaporate without having the cork get too wet.

A rule of thumb is: cork underlayment should never be stapled, nailed or screwed into place (it should never be pierced by metal/materials). This will cause the cork to loose its acoustic properties as well as cause it to deteriorate (from rubbing up against hundreds of nails, it begins to flake/fall to dust).

A cork underlay should never be glued directly to cement slab below grade. Water based adhesives do not like the moisture that evaporates off of a pad. You run a large risk of the underlay lifting and the floor becoming unstable.

Our cork underlayment is just what the Condo board asked for! Cork is perfect for reducing sound transmission from upper to lower level living spaces. It is excellent in protecting the flooring and the subfloor from rot and degradation. Cork is widely used for sound reduction in buildings. It is an ecological, economical and effective way to meet building codes for sound control. Cork underlay can be used under tile, marble, laminate, cork floating planks and hardwood floors. We offer our cork underlayment in three sizes – 3mm, 6mm and our new baby 12mm.
