ABSTRACT
Movement joints are an essential aspect of any floor finish and not only where elevated temperatures are experienced. The range of ambient temperature will influence the frequency of the joints, but all substrates and finishes not elastic in nature will require a joint to absorb:
— Slow permanent growth due to moisture absorption or chemical reaction. — Slow, gradual temperature variations as occurring in seasonal changes. — Slow, gradual substrate variations due to change in humidity levels as a result
of change of use of building or seasonal changes. This is particularly relevant to areas of high groundwater content.
