Tremco Vulkem 116 Polyurethane Sealant 10.1 oz. (1, Black, Single)

This is the standard general chalk used throughout the construction industry to coverup mistakes because today’s workers can not measure and cut precisely.

Muy buena calidad, me funciono PERFECTO

Vulkem is always great product but returned it as I decided to do something else.

Better than foam, I like the density of urethane once cured. I use it to support the ends of flashing where cavities can occur. Then I can go back in a week or so and put a top coat over those locations. It offers more control than expandable foam

Curing is a slow process. It took the better part of a week to set up completely.

bla ..bla ..bla

I use this product to seal the seams in my birch bark canoe. This product and those like it are the only non-natural products used by birch bark canoe makers. It does the job better than the traditional mixture of bear fat, pine pitch, and charcoal! I realize that this review will be of no use to most everyone, but simply had to let it be known that this product has more than one use!

Easy to apply.
