Can a new wood-look floor go down on concrete with leftover adhesive?
The old carpet was already gone before the crew arrived, but the concrete still carried the carpet adhesive across about 870 square feet. Gluedown LVP bonds directly to the slab — it has no underlayment to mask what's underneath — so any residue left on the concrete will telegraph through the new floor.
The preparation was methodical: scrape the adhesive, apply patch primer, and skim coat the full 870 square feet with 14 bags of Planiprep SC, then remove and dispose of 49 square feet of existing VCT. A toilet in the work area was removed and reset as part of the flooring scope so the new floor could run cleanly beneath it.
Only after the substrate was flat and sound did the 936 square feet of Karndean Opus Natural Walnut go down with the specified adhesive, with 56 pieces of cove base finishing the perimeter — a wood-look floor for a space being prepared for tabletop gaming and collectible-card retail.
Project overview
The goal, materials, and finished scope.
In August 2026, Floors Now completed a 936-square-foot commercial flooring project in Berlin for a space being prepared for tabletop gaming and collectible-card retail use. The old carpet had already been removed, but leftover adhesive remained across much of the exposed concrete. The crew scraped and skim coated 870 square feet, used patch primer and Planiprep SC, removed and disposed of 49 square feet of VCT, coordinated a toilet removal and reset, and installed Karndean Opus Natural Walnut WP326 gluedown luxury vinyl throughout the commercial space. New cove base completed the perimeter.

Common questions
Questions about this commercial flooring project.
What flooring was chosen for the gaming retail space?
Karndean Opus Natural Walnut WP326 gluedown luxury vinyl plank — a wood look for 936 square feet of a space being prepared for tabletop gaming and collectible-card retail use. The business name and address are withheld for customer privacy.
What is cove base, and why does a commercial floor need it?
It is the finished trim where the floor meets the wall. We installed 56 pieces of cove base with cove-base adhesive around the perimeter, giving the commercial space a clean, finished edge.
What condition was the concrete in before installation?
The old carpet had already been removed before we arrived, but leftover adhesive remained across about 870 square feet of exposed concrete. We scraped the adhesive, applied patch primer, and skim coated the area with Planiprep SC before installing the new floor.
Why is concrete preparation a separate step before gluedown LVP goes down?
Because gluedown flooring bonds directly to the slab, with no underlayment to hide what sits beneath it. Here that meant scraping 870 square feet of adhesive residue, applying patch primer, and skim coating with 14 bags of Planiprep SC — the new floor only performs as well as the surface it is glued to.
