I smell someone who has an assingment due, he didn't pay attention in class, and is too embarassed to ask his instructor how to do it.

Do it in accordance with the Building Regulations.

In the UK, a significant change in the outside appearance of the building would need to go through the local authority's planning process. Once approved, a qualified local builder or rendering specialist should be contracted to carry out the work. With the contract comes a long-term warranty that can be attached to the rest of the documentation for the building, which in aggregate will form a robust defence to any temptation for potential buyers to carry out "gazundering" prior to any sale taking place in the future.

Rendering an entire building is not the province of the inexperienced amateur, however well the intention.
