Mix the 2 parts of the RTV silicone (aka Bunion Putty) in equal amounts. A standard toe separator usually requires about half a tablespoon of each component. Mix the 2 portions thoroughly and then let it rest for 1 minute as the material hardens. When slightly firm, place the silicone between the first and second toe, keeping them slightly separated for the 2 minutes it takes the silicone to harden. When firm, remove and place it aside as it will take another 5 minutes for it to completely cure. After that, it’s ready to use.
