Many in the construction and floor covering installation industries are aware of moisture tests that occur before installing floor covering materials on concrete. Hopefully, more and more are becoming aware of the requirement to test for substrate surface absorption/porosity. Unfortunately, not as many are aware that almost all manufacturers either strongly recommend or even require adhesive bond tests before the complete installation of their products on a project. Thus this critical pre-installation evaluation often goes overlooked, or perhaps even worse, incorrectly carried out.
