| Writing |
Superior, low gloss
matte finish readily accepts chalk,
providing a sharp, unbroken line
with less pressure and maximum surface
adherence. |
| Visibility |
Contrast/waviness for chalkboards
(light and dark effects) shall be
no less than 20 when tested with
the contrast measurement test with
773-gram load on chalk. Resolution
(visual acuity) shall be based on
3 lines per degree and be visibly
maintained beyond the current standard
of 3 meters. [Byk-Gardner measuring
device] |
| Erasing |
Erases easily with a dry cloth
or standard chalk eraser, retains
minimal residual chalk dust, and
will not leave "ghost writing."
Color change (dark/light) after
chalk erasing is reduced 60% from
traditional surfaces. |
| Cleaning |
WET ghost measurements on chalkboard
surfaces before and after wet cleaning
shall not exceed a factor of 0.49.
Easily cleaned with most mild soaps
and detergents. Surface not affected
by most strong cleaners and basically
non-staining due to non-porous surface.

| Wearability |
Vitrified glass-hard ceramic surface
fused to light gauge enameling grade
steel at approximately 700°C.
High resistance to impact damage,
abrasion, scratching, and color
fading. |
| Magnet
Capability |
The P3
ceramicsteel®
surfaces are ideal for all magnets
and magnetic impregnated materials
and will not be scratched or damaged
from the contact. |
| Flame
Resistant |
The P3
ceramicsteel®
surface is 100% non-combustible. |
