4.11. Plastering the roof
This is a very important stage and
can be achieved through a variety
of materials. For example sand can
be used with asphalt and should
be mixed together at a ratio of 1:2
(asphalt / sand). In this case the
asphalt should be heated first and
dried with gasoline or kerosene
before being mixed with soft sand.
It should be applied to the roof in a
layer 2cm thick which will protect
the roof from rain and humidity.
4.12. Plastering the walls on the
outside
The plaster for the outside walls is
made using sand that is mixed with
local materials such as coloured mud mixed with sand or lime.
Local skills and expertise may need to be used at this stage.
This can also be done at an earlier stage as shown in picture
23.
4.13. Plastering the inside walls
Plastering the walls on the inside is made using sand that is
mixed with gum arabic powder. Like the outside walls other
local materials can be used such as coloured mud mixed with
sand or lime (see picture 24).
4.14. The Floor
The floor in most rural homes uses a thin layer of sand and
that is the most appropriate method for this building. If this
house was to be built in an urban area the ground could use
braided brick, stone, concrete or tiles.
