I'm going to be treating beechwood counter tops with linseed oil (following these instructions).
The person in control of the budget has asked me to figure out how much oil will be required (so we don't buy too much).
The tops are 40mm deep.
How many ml of oil should be used to give a single coat to a 1000mm × 1000mm × 40mm block of beechwood?
I am assuming it will be the same amount for each coat, so let me know if that assumption is wrong.
Is there a heuristic I can use to work it out for other thicknesses?
Given that, I can figure out the total required from the number of coats and reapplications.
