1 gallon (3.785 Liters) of VaporRemed treats about 100 square feet of concrete and wooden surface. 1 gallon VaporRemed effectively treats 20 square feet on dirt. The reason for this difference is the depth that oil and our products travel with the oil.

Note for international users : 3.785 liter treats about about 10 sq.meters of concrete and wooden surface and about 2 sq.meters of dirt/soil.
