I have now sanded and treated one of three rooms. The lye cost 100kr/L. It took 4 liters for 20sqm.
The other rooms are larger, and I wonder what is reasonable to pay for lye. Last time, I bought it in connection with renting a sander, so it probably wasn’t at the cheapest place.
You have to save in all areas...if possible...and not affect the result...
