Importance of identifying the needs of the substrate

In many cases we have been to sites and viewed substrates that have different requirements for different areas of the same substrate. A factory floor often will have high and low traffic areas in the same work-space. Wine-cellar walls often have wet areas where lower sections of walls need more specialised coatings than the remainder of the wall. Exterior walls often have exposed plaster or brickwork below the damp proof course that need a different coating than the upper walls.
It is important for a contractor or specifier to identify these requirements before coating work commences, so that the correct combination of products can be used. This saves a lot of money in the long term and keeps the coated structure looking its best for the longest period of time possible.
