How much floor lacquer do you need?
Liters of floor lacquer for parquet and wood floors — typically three coats.
Quick answer
Floor lacquers are formulated for abrasion — that means more coats than wall paint, usually three on bare sanded wood. Each coat adds film build; skipping the middle coat is how you get white marks under furniture legs six months later.

Floor lacquers need more coats (often three) for abrasion resistance. Yield is similar to wall paint on smooth sanded wood.
How it works
Yield on smooth sanded parquet is similar to wall paint (~10 m²/L per coat), but the first coat on raw wood can drop to 8 m²/L through absorption. Use advanced settings for your manufacturer’s data and can format. A floor lacquer kit with applicator pad often wastes less than a wide roller on edges.
Sand the floor through progressively finer grits before the first lacquer coat — skipping 120 grit shows through the film forever. Replace floor sanding discs as they glaze; apply with a floor finish applicator on the field and a narrow floor varnish brush along skirting and radiator pipes where pads cannot reach.
Walkable and cured are weeks apart, and the gap is where floors get ruined. A lacquered floor takes footsteps after hours but reaches full hardness in one to two weeks — put the rugs down and slide the furniture back on day two and you trap solvent under them, leaving dull patches in the shape of whatever sat there. Leave it bare as long as you can stand, put felt pads on every leg before anything goes back, and lift furniture rather than sliding it. Work along the boards and towards the light from the window, so the lap lines fall where the eye does not catch them.

Frequently asked questions
Why three coats for floor lacquer?+
Coat 1 seals the wood, coat 2 builds body, coat 3 adds wear resistance. Two coats can work on low-traffic closets; living rooms and kitchens should stay at three unless the product is a one-component high-build system saying otherwise.
How much lacquer for 25 m² of parquet?+
25 m² × 3 coats ÷ 10 m²/L = 7.5 L before waste; with 10% → ~8.3 L — often two 5 L cans or three 2.5 L depending on what the shop stocks. First coat on raw wood may push toward 9–10 L total.
Can I use wall paint on floors?+
No — wall emulsion lacks abrasion and chemical resistance. Use a dedicated floor lacquer or oil. The calculator presets three coats and product-specific yield for that reason.
How long before I can walk on it?+
Light foot traffic is often 24 h; furniture after 72 h–7 days per label. Buying the right liter count matters less than respecting cure time — premature moves cause permanent marks you cannot sand out without recoating the whole room. Keep pets off until the final coat has fully hardened.
