I don't know about you but I'd always considered concrete to be a pretty boring medium used to build houses and such but recently it's had a seriously sexy makeover. From polished concrete floors in super trendy apartments to sleek furniture made with the grey stuff, there is no denying it, concrete is cool. So no wonder that the concrete planter making workshop with Robert from Tri-Geometrica is so popular.
This is the second time we have run this class so expectations were high and it didn't disappoint.
The class starts with learning how to make a mould. Robert brings almost everything you need on the night and this stage involves a scalpel but you have to supply you own steady hand!!
Once the net of each of the planters have been cut out of the special paper, then comes creasing, folding and sticking.
Then the moment that everyone has been waiting for! The Concrete!
So there is a bit of a technique to mixing and achieving the right consistency but Robert talks you through the whole thing after doing a quick demo. You get to mix up your own wee batch of concrete to pour in your moulds. Doing it this way allows you to get a feel for the mix and really take ownership of the whole make.
The next step is to pour the concrete into your moulds and it's as easy as that - concrete planter finished right? Wrong! If you left it just like that, there wouldn't be any space to plant your dinky cactus. So with a silicone insert filled with weighty ball bearings, you wriggle each one into the filled mould to create the right space to house a plant. Then the hard bit - you need to leave them for a whole week for the concrete to set before finding out what they look like!
So until next week....
