Installing designer floors yourself - hardware store vinyl or specialty shop?

You want to lay flooring over the expansion joints?! Then check if it is possible with the material, consult the underfloor heating installer, and prepare the expansion joints accordingly.

We would like to lay a room measuring 10 x 4.5 m completely, which should basically not be a problem, but after further research it seems that it would be better to choose a floor that can be glued. We would definitely follow the manufacturer’s instructions.

1) Gluing
2) That’s not a problem.
3) This is how it goes: vacuum the screed. Dust-free. Roll on primer. Wait a few hours. Mix leveling compound (Kugato flows and is ready, for example) exactly according to the bag instructions. Pour it on, spread it out. Wait. 24 hours. Now another sanding because of small burrs and such. Vacuum. Design planks should lay warm beforehand, it makes them more flexible. Apply adhesive with a notched trowel, initially only one row. Lay the floor. Cut at corners and edges with ruler, square, cutter knife. One person spreads adhesive, one lays plank by plank. Always tap the plank firmly with the fist as well.
Materials we used: Mapei leveling compound eco, Mapei primer for floors, Mapei adhesive, Project Floors design vinyl plank at 19.00 and a few cents.
Installed quantity: about 60 sqm in three rooms.
Time: two people, one weekend. Baseboards mounted with adhesive from Döllken.

Correction. Please read above Lugato flows and finished.
