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

First time I’ve ever attempted to do my own silicone sealant and this worked a treat. Gace a smooth professional finish. Excellent product

This is a really good idea and on two smooth surfaces it would have done the job in a lot less time than with other tools but unfortunately, with small marble tiles the slightest ridge was not easy to negotiate. With a solid grip, I still think that this is a good product and I am glad that I gave it a try, keep it for the next job which is a totally smooth surface and behind taps.

Actually better than I thought. Did a great job

You waste a lot of sealant and I mean a lot.

Excellent results

Makes a nice bead but block was too thick to get behind my bath taps, thinner option please

Does exactly what it advertises Made the job so much easier and neater and I have used sealants for years Wish I knew about this before now👍

Great idea.... In theory! Crikey, I've never had such a poor finish on silicone. This, I imagine, would be good on a straight run that tapers off to nothing on the finishing run. As soon as you lift it, it leaves a lump. There is SO much waste too. To get the 8mm finish, about twice as much sealant is required just to get the block to pick it up. Cleaning the block is a nightmare with the textures and writing embossed in it. I went over the run I did with my years old tried and tested method (fat sausage finger dipped in water). I had high hopes for this gadget but was really disappointed.

This thing makes grouting and applying siliconized acrylic so much easier and cleaner. It works pretty well on its own even over uneven tile. Add some painters tape and you have yourself a very good two prong solution.

a waste of money!

Easy to use.

Item difficult to handle and to clean while using.

Still leave few marks but it help a lot
