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

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.

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.

I saw this on YouTube and wasn’t sure it would be as easy to use as it showed but as it’s not too expensive I ordered one. It is fantastic and easy to use to get a great finish on silicon. Just follow the instructions. This one is for 6 and 8mm beads. Hopefully they will make one to do smaller beads as well.

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.

Really well made with different width silicone bead sizes as required..cut the nozzle to requited bead width and away you go.

Easy to use and works well.

My only grip, it give two bead triangles 6mm & 8mm I find these large for most applications wish it was 4&6.

This item works really well, at least mine lines are straight now.
