Good Practices
Façade
- Good detailing of architectural finishes can affect the appearance and durability of the plastering and careful consideration should be given to their design.
- In order to reduce dark stains marking on walls, good designs which incorporates a outward projecting sill or overhanging eaves should extend beyond the lines of reveals. See Figure 1. Besides sills that incorporates a effective throat or drip on the underside to prevent water running onto the wall below, or on to jambs.
Plastering
- When plastering is vulnerable to the penetration of moisture, advantage should be taken special features to provide protection. Care should be taken that features do not adverse effect upon the plastering or its protective properties.
- On smooth plastering surface, the rain will distribute the dirt that it carries throughout the path of its flow resulting in irregular, streaky, or patchy discolouration.
- However, if a rough finished textured plastering is employed, it will break up the flow of water and spreading the rainwater and its dirt at a more uniform way.
