OBSERVATIONS:
Guardline A.R.C. significantly outperformed competitive
coatings in both 8 hour
and 7 day tests. When tested 7 days after the coatings had
been applied, A.R.C. developed
over 7 times the abrasion resistance of the best of
the competitive products.
In just 48 hours after coating application, A.R.C was over
20 times more abrasion resistant.
CONCLUSIONS: Guardline A.R.C. was clearly the most
abrasion resistant
of any of the coatings tested.
In fact, Guardline A.R.C. is, without question, the most abrasion
resistant coating that we have tested. We were not only surprised
with the extremely high level of abrasion resistance recorded in the 7
day test; we were very impressed with the rapid development of abrasion
resistance indicated by the 48 hour
test. In just 48 hours
after application, A.R.C. had already achieved 86% of its 7-day abrasion
resistance. Consequently, in actual industrial floor applications,
we would
expect A.R.C. to provide
a much longer service life than any of the competitive
coatings tested.

TEST METHOD:
Each
coating was applied by 6 mm pile roller in two coats to smooth
concrete slabs and allowed to dry/cure at room temperature. Abrasion
tests were conducted at
two intervals after the application of the second coat: at 24 hours,
and at 7 days. Abrasion testing was performed
on a standard Gardner-style Scrub Tester, using Diamond Grit
No. 220 Wet Abrasive Paper, kept wet by water spray and changed every 1,000
cycles.
Cycles to Fail indicates the number of back-and-forth
cycles required to wear through the coating film and
expose a minimum of one square inch of the concrete substrate.
