How to lay cork floor tiles
Updated: 21 October 2026
How to lay cork floor tiles depends on the construction in the box: a glue-down or peel-and-stick square is stuck and then finished, while a click plank floats and must be free to move. The Products Compared editorial team used the Treefloor install guide, Flooring by Nature’s sheets, and the three amazon.co.uk packs in our [cork floor comparison](/hub/flooring/cork-floor). We did not fit a floor. A qualifying purchase can earn a commission at no extra cost to you.

Prepare the floor and the packs
The subfloor wants to be dry, clean, and flat. BS 8203:2017 covers resilient floors, including cork. A common hygrometer line is 75% relative humidity, and several cork sheets say 65%. Use the lower figure. Acclimatise the packs closed. Flooring by Nature’s tile sheet says two days, then open them only when you lay. On that sheet heating stays off for 48 hours and returns after 72 hours, with a surface cap of 26 °C.
Glue-down and self-adhesive tiles
Glue-down cork uses contact adhesive on the tile and the subfloor. Flooring by Nature wants it dry to a clear, tacky film before you press. The Treefloor squares are self-adhesive, and the maker still calls the cork unsealed. The install guide says a water-based polyurethane, an almost dry first coat, then about five light coats. An over-wet coat cups the tile. Treefloor says do not seal for 48 hours. Corkfloor.co.uk says wait 24 hours, then three coats. The leaflet in your pack wins. A bathroom is cork flooring in a bathroom, not a third varnish method.
If the tiles curl
Curl on these thin tiles is usually the top shrinking while the back is still held. A heavy first coat of water-based varnish does it, and so does wet adhesive. UK buyers on the shared listing file, including Jimfort, syzygy, and Bekki, describe curl after sealing Treefloor tiles. A 4 mm tile will not sand flat. Lift the pieces while the adhesive will still release. A pin board or a small trial is the narrower job on best cork flooring.
Click planks and the gap
A click cork floor floats, and UK law sets no single expansion gap. Flooring by Nature uses 10–15 mm. Walls and Floors uses 10 mm, with extra gaps past 10 metres or 100 square metres. V4 Cortejo sets a minimum of 5 mm. Fit the figure on your plank’s leaflet. Stagger end joints by at least 30 cm, and keep the last row at least 10 cm wide. Fix the skirting to the wall, not the floor. Do not copy a glue-down bathroom instruction onto a floating EarthTone or Montano plank.
When you should stop
Stop when you cannot show the floor is dry. A new screed, an anhydrite screed, or a slab with no hygrometer reading is a fitter’s measurement. Stop when the heating has no floor probe, or the room is a bathroom or can flood. A varnish tin is not that permission. A use class is not printed on the Treefloor listings. If water is part of the brief, hand over the moisture reading.
Common questions
Do I glue self-adhesive cork tiles as well?
The Treefloor tiles are sold with a peel coat, and the maker still describes them as unsealed and still mentions a flooring adhesive. The peel coat is not a licence to skip the finish, and a second glue is not a licence to lay into wet adhesive. If you add adhesive, it has to be the type the sheet allows, and it has to dry to a tack before the tile goes down.
How soon can I varnish?
Follow the leaflet in the pack, because the published waits do not agree. Treefloor’s web guide says not to use or seal for 48 hours after fitting, then light coats of water-based varnish. Corkfloor.co.uk tells you to wait 24 hours and then apply three coats. Starting the same evening, while the adhesive or the room is still damp, is the wet-coat problem their own warning describes.
Why did the tiles curl after I sealed them?
The usual cause is the top shrinking. An over-wet water-based varnish, or a coat put on before the tile has settled, pulls the face while the back is fixed. Wet adhesive that never flashed off does the same from underneath. Treefloor’s guide says start with an almost dry roller and about five light coats. A 4 mm tile that has already dished will not sand back to flat.
How big an expansion gap does click cork need?
Use the figure on your plank’s sheet. Flooring by Nature prints 10–15 mm, Walls and Floors prints 10 mm with extra provision over 10 metres or 100 square metres, and V4 Cortejo prints a 5 mm minimum. None of those is a national rule for every brand. Stuck tiles do not borrow the floating gap unless that tile’s sheet says so.
Do I acclimatise with the boxes open or closed?
Flooring by Nature’s tile sheet says two days in the closed packaging, in the room, and unpack only when you are ready to lay. Open boxes on day one can let the faces move before they are stuck. If the click-plank leaflet gives a different number of hours, use that number for those planks.
When should I call a fitter?
Call a fitter for a new or anhydrite screed, for any floor you cannot read with a hygrometer, for a bathroom or a room that can flood, and for underfloor heating with no probe in the floor. Also call when the lease asks for a use class or a fire class and the pack you hold does not print one. A straight, dry bedroom in click cork is a job many households do themselves if the gap matches the sheet.
