Coverage Calculator
How many litres of finish, primer or oil you need for the job. Pick the product, enter the floor area and number of coats.
How this works
Calculator uses Bona's published coverage rates. Open-grain and dense species absorb more, so we add 15% for those. We always add a 10% waste buffer on top because real jobs use more than the bottle says. Final number is rounded up to whole pack sizes Sand-Aid actually stocks.

Ring 1300 950 551 with the species, square meters and the topcoat you want and you'll get a spec on the call -- including the right primer, intercoat sequence and trade pricing.
