Question 1a:
There are two different type of finish that could be applied on the building chosen, inherent finishes and applied finishes. The major finishing works that could be applied on the floor are; joint-less finishes such as cement screed, granolithic paving, anhydrite floor finish and resin-based finish; flexible thin sheets and tile finishes such as Linoleum sheets and PVC sheets; rigid tiles and stone slabs finishes such as clay-floor tiles and natural stone slabs; and timber floor finishes such as natural wood-floor finishes, floor boards and wood strips flooring.

The major finishing works that could be applied on the internal wall are fair face finishes such as fair face blocks or block work; internal plastering such as lime plaster, cement plaster and different type of gypsum plaster, gypsum plasterboard, wallpaper, painting and decorating such as paints, wood stains, vanishes and oils.

The major finishing works that could be applied on the external wall are: painting and decorating such as paints, wood stains, vanishes and oils; external rendering such as smooth or wood-float finish, scrapped-finish, textured finish, pebbledash finish, roughcast finish and machine applied finish.

Question 1b:

For the external floor finish, granolithic paving with exposed aggregate is used. Within the hallway to the lobby and the stairway, ceramic tiles with the same granolithic paving were used the floor finish and skirting. In the lobby and the other levels, polished marble tiles were used for the floor finish and carpet is used for the PA office.

Several finishes were used for the external wall. Decorative masonry tiles were used for the lower external wall finish. For the upper p...

...rescence on masonry building surfaces where the hygroscopic salts in the wall absorb the moisture and move to the surface of the wall when the moisture evaporates, forming a built-up of the said salt on the surface, causing aesthetic and structure damage.
Rising dampness causes bleaching and the paint on the wall to peel, resulting in the corrosion of materials due to direct exposure to the environment.
When rising dampness occurs near the timber-based materials, the material became deteriorated due to warping and buckling. The timber may also be affected due to the growth of decaying organisms, causing the timber structure and finishes along the base wall to rot and decay.
The damp conditions cause the growth of moulds on both porous and fibrous materials. This causes damage to the finishes, both aesthetic and physical, and poses health hazard to the occupants.
