Concrete pot making

instructions
Concrete Pot Making
-
Dricon, high strength (pothole) concrete 20kg-3L water
-
Spray containers with lubricant, I am using cooking oil but I have also use CRC and they both work fine.
-
Place a straw in the precut hole, this acts as a drainage hole for the planter.
-
Weigh out the mix. My outside container was 2.4kg size and the inside was a 700ml capacity size and I used 3kg of concrete and around 450ml water
-
This is a 1 kg batch, mixed and ready to add to my mould. It really does not take much mixing at all. I generally only mixed until I could see no more dry concrete.
-
The first batch I packed in around the straw, pushing some up the sides.
-
Place the small container inside pushing the straw through the hole. Fill with concrete mix pushing down to make sure no gaps.
-
Weigh down (inner container) and leave to set.
-
Finished pot, I de-molded after around 7hours, but it will take a number of weeks(3) to full.
