DIY Sugru – Mouldable Rubber

I stumbled across the term Sugru (aka Oogoo, or Formerol) less than a fortnight ago, and will never look back!  It’s being called the “21st century Duct Tape”, and can be used for just about every conceivable fix-it job around the house.

I ordered some online, but the packages are far too small to be economical for larger needs; so I found a recipe to make my own.  This recipe has variations all over cyberspace, but I’ll give you the result-recipe I tried.  I used it to make a drain cover for one of our showers that was custom-built and thus has an odd size of everything and standard drain covers don’t fit; I took a piece of non-metal screen material and sugru’d the edging.  With the extra bits I made new rubber feet for a heavy glass cheese tray (this is Switzerland, after all), and a few caps for sharp tools in the crafts room (as well as a cap for the opened silicon cartridge).  I think I’ve found my new favourite household elf!

This recipe will give you white Sugru; for coloured, just add a couple drops of food colouring or acrylic paint.  Below is a colour chart for food colouring mixtures to give you an idea of ratios.

What you’ll need:

pure Silicon caulk (found in most DIY stores) (see image)

caulking gun (see image)

corn starch / corn flour (here in CH, I used Maizena)

a plastic cup and plastic spoon or stirring stick

a bit of water

Mix the silicon and corn starch 50/50 in the plastic cup, stirring thoroughly with the plastic spoon (word to the wise:  DON’T use your hands until it’s formed a pliable ball, or you’ll be picking silicon off your fingers for days – trust me on this!).  Once it’s formed a ball, dust your hands generously with corn starch and knead the ball a minute or two to cure it.  Then use it for whatever you need.   Add a drop or two of water if needed, to smooth the mixture.

It will take 24 hours to harden before using the repaired or created object, so set aside your project once it’s done to your satisfaction.

For ideas on how it can be used, just do a Google image or YouTube search for terms like “Sugru hacks”, “Sugru repairs”, or “Sugru craft ideas”.
