blackjack

While Blackjack #57 ("premium rubberized coating for waterproofing roofs & foundations") is being tried and true on this forum, I absolutely unable to get it in my province (we don't even have Lowes here and they won't ship). Would Black Knight "18.9L All Season Rubberized Roof Repair" from HD...

The manufacturer does not recommend for use around livestock due to the petroleum chemical makeup. However they do offer a silicone based product. At Lowes it is called Blackjack Silicone Waterproofing Coating. At Home Depot or Amazon it is called Eterna-kote. There is your answer, short and sweet.
