Sam working on Haiti Communitere's cob plaster.
A wall in the main building of Haiti Communitere was being plastered by Sam in the image to the right. Sam's plaster has been used to finish many of the walls of various structures throughout the Haiti Communitere compound. For this wall plastic water bottles were stacked between an earthen mortar before being finished with an earthen plaster.
The mortar was 1 part river sand, to 1 part dirt, to 1/2 parts straw. Water was added before applying the mortar.
The plaster was 1 part white sand to 1 part clay. Water was added until a slurry consistency was reached. After applying the plaster a layer of water mixed with white wood glue was applied to the wall followed by a layer of paint.
The caps were cleaned before the final finishes were applied.
Some spaces were left more open to accentuate the plastic bottles.
