Hot Rubber vs. White Elastomeric:
What’s the difference at your grain bin foundation?
The bin-to-concrete joint is one of the most important areas to seal. MSW hot-rubber grain bin sealant is designed to create a thick, flexible barrier at that transition—helping seal out moisture while keeping aeration air inside the bin.
White elastomeric products are liquid-applied coatings that can look good initially, but they rely on adhesion to the concrete. When a coating cracks or peels, moisture can travel behind it and reach the steel-to-concrete joint.
When a white elastomeric coating fails, trapped moisture can remain against the steel at the bottom of the bin. Over time, that hidden moisture exposure can lead to corrosion and rust at the bin base—damage that may not be visible until it has become a much bigger and more expensive problem.
Choose a system designed for the job—not just a coating that looks good on day one.
