concrete colour samples

deb and i have been installing the concrete drawings we did. i have some photos of the process but i cant show them yet. i will eventually. 

but as you can see from the photo above we are not done yet. the small holes are from the lifters that we used to lift and crane the large sections of the concrete drawing into place. now we have the tricky task of patching these holes and matching the colour.

since we are new to this process we have decided to do a series of colour tests. each bucket has a different mix of concrete path mix, and oxide. they all look grey until you add the water.

once you mix in the water the oxide takes over and colours the concrete mix. we have done various mixes for each of the 4 colours we are trying to match. above are the calipso green samples

 

these are the white colour samples

  

and the black colour samples

it was very satisfying seeing them all lined up and measuring out the oxides to exacting quantities. we need to let the samples dry for about 10 days and then we will take them to the install site and see which one is our best choice. then we can begin the final patching process.
