ABSTRACT
A bstract The increasing use of spray applied materials for structural repair has highlighted the need for meaningful and reproducible testing regimes. While the manufacturers of pre-bagged materials provide a wide range of test data on which to base specification, it is not always apparent which attributes are most important and how the material as applied can be shown to be fit for purpose. This paper reviews aspects of performance testing for such materials as supplied by the manufacturer and as obtained on site. Results from a large repair programme are used to illustrate aspects of the testing and validation of repair materials in-situ. Keywords: Repair, site testing, pull-off tests, interpretation of results.
