FORM TREATMENT
High Density Overlay (HDO)
High Density Overlaid Plywood is the standard "workhorse"
of the concrete industry. Producing uniform surfaces
and offering high reuses, HDO Plywood is ideal for most
engineered forming systems. With HDO Plywood, cost-
per-pour is low. It's tough resin overlay resists the alkali
complexion of concrete and the scouring action of
aggregates, enabling it to last far longer than BB-grade or
MDO plywood. With reasonable care, 25 plus reuses can
be expected. HDO Plywood gives concrete a smooth,
glossy finish. Surface discoloration is held to a minimum
because the overlaid veneer is impermeable and non-
absorbent which keeps hydration uniform. The smooth face
of overlaid plywood promotes the evacuation of air during
consolidation, reducing bugholes and honeycombing. HDO
Plywood minimizes grain and patch transfer as well. Since it
keeps its finish longer than ordinary plywood, HDO Plywood
assures a more consistent surface appearance. With HDO
Plywood, stripping and clean-up are a breeze. It's non-
absorbent so form release agents stay where they can do
the most good—on the face of the panel. After a pour, HDO
Plywoodrequires minimal clean-up for subsequent pours.
Medium Density Overlay (MDO)
For moderate reuse at a cost that's comparable to BB-grade
plywood, Medium Density Overlay Plywood is an excellent value.
MDO Plywood is best suited to applications where a glossy finish
is undesirable or where a final finish of paint or acoustic texture is
specified. MDO Plywood will leave concrete with a matte finish
that readily accepts coatings. This same matte surface helps MDO
Plywood hold release agents uniformly in place so there's less
blotchiness from uneven hydration.
Finish Form
Finish Form provides a superior concrete finish, leaving your
surface smooth, clean, and consistent. It's high durability of scuff
and abrasion resistance is excellent in strength. This increases
panel reuse in concrete forming. For exterior use: Panels resist
severe weather conditions. Finish Form is edge sealed to prevent
moisture from penetrating. It is Ideal for exposed or Architectural
concrete, yet cost effective for clad structural concrete. Finish
Form's quality material results in an increased number of pour and
optimum usage (unlike many other domestic forms). Finish Form is
a hardwood panel and with more plys than domestic form.
