Common floor finishes
• The functions of floor finishes, which are the finishing layers over or covering of the structural floor, have been aptly summarized in Bibl. 21.11 as follows:
- to have a high wearing resistance and long life span;
• Some common floor finishes are illustrated on the following pages, showing a variety of good construction details.
• Since in developing countries a number of activities (eg food preparation, cooking, playing games, meeting friends) take place outdoors (on verandahs, in courtyards, on rooftops, etc.), an example of verandah floor construction is also shown. Further information: Bibl. 00.55, 21.11.
Verandah Floors (Bibl. 00.55)
• The construction of a verandah floor differs from that of an indoor floor in three ways:
• Verandah floors are built with a small slope (about 1 %) towards the outside, so that rainwater can run off quickly (a).
• A projecting outside edge (b) is provided (2 or 3 cm are sufficient) to prevent the development of cracks, which would otherwise soon appear along the edge.
• Expansion gaps, filled with wet sand (c), are constructed to accommodate thermal movement caused by direct exposure to the sun.
