I used this to fill gaps in old pine wood flooring. It was perfect and has held up well. As others short commentators sikaflex commentators have noted, this isn’t like silicon caulk, but it is similar and you need to be careful with it.

Used rubber 4'X6' rubber flooring for home gym. This sealant worked great to seal cracks and smooth out uneveness of height of adjacent mats. Room looks like one large, smooth custom fitted flooring. Easy to apply and work with.

I used this to seal the base of my lathe against coolant leaks. Would recommend.

We started using this for horizontal gap filling between door/window sill pans and the actual sills. The viscosity is awesome as it works its way into the tiny gaps and levels itself. No other caulk we've found works as well as this to prevent water penetration.
