Product Detail:

• Metal tool for creating perfect radius corners in concrete precast forms.
• After placing a bead of silicone in the corner of the form, or along a sink mold, simply run this tool over the silicone and it will create a perfect bead every time, in any direction that you hold the tool.
• Other caulking tools made of plastics, wood, or other substances will wear down over use, and end up creating ridges and lines in the silicone radius. This all-metal tool won't wear down.
• The ball feature of the tool makes it easy to transition from a horizontal to vertical corner, and ensures the exact same radius on all corners.
• Tip: When smoothing out silicone (Silicone Type II usually works best), the more silicone that gets pushed to either side of the ball, the easier it is to remove after a few hours, when it's hard enough you can grab and peel off the excess.
