of success obtained with the overall project. It is crucial to examine
the history of the contractor firm and its applicators. Ideally,
the contractor /applicators would have 5 to 10 years of application
experience with the specified type of flooring system.

with the building operations should be arranged so that each has
full knowledge of the particulars of the flooring work and be able
to co-operate in producing the conditions required to complete a
satisfactory project.
