Is it possible to buy one or two gals of Okon S-40 instead of six?

For the current project I am working on I do not need 6 gal.
Asked by: FastFed
I needed 5-6 gallons, I do not know if you can buy 1 or 2 gallons

Is this item available by the gallon in stores?

Seems like you have to order either a case (6 gallons) or 5 gallons worth.

Asked by: Guss
No, Guss. Rust-Oleum Zinsser Okon S-40 is for exterior use only. OKON S-40 does not provide protection against hydrostatic water pressure. If you wish to prevent moisture from penetrating into your basement we recommend Zinsser Watertite LX.
