Metex Silicone Block - 5 In 1 Easy Grip Sealant Shaping & Finishing Caulking Tool - Creates A Consistent Width Bead. Sharp Internal Corners With Of 6mm Or 8mm Bead - Packaging May Vary

Simple to use, great result. Don’t over apply silicone, then it works a treat.

Theres a bit of a knack in using it properly, but it does a good job once you get the hang of it.Even so, the bead is a bit thicker than I would have liked.I saw the manufacturer were talking about producing a 2nd model which could do smaller beads, but after a couple of years nothing seems to have come of if, which seems like a missed opportunity.

Excellent gadget for a perfect finish

PROS: creates a neat and well-shaped silicone fill, when used in ideal conditions.CONS: quickly becomes inundated with silicone, particularly if you have dispensed a little too much silicone from the gun. The block was so messy by the end of the job, I decided to discard it. The flat tabs designed for this task look like a better prospect, because they are so much easier to keep clean.WARNING: carefully lay down wide masking tape before using - silicone can escape from around the block while using it.

Works a treat , should have brought one years ago

Follow the instructions and it works really well. It's easy to use but make sure you have plenty of paper towel to remove the excess.

A lot trickier to use than expected and leaves very large strips. Far easier better with the smaller flatter version

Good product good price
