What is the difference between HDO and MDO plywood?
HDO uses a denser phenolic overlay that strips glossy and near-mirror when the pour and release stay clean. Buyers often search MatteFace Plywood (MTF) as MDO formwork plywood; the mill product name is MatteFace, and MDO stays the search token. APA kraft-paper MDO is paint and signage, not our formwork CTA. Pick by finish and reuse target, not by which acronym sounds denser.
Is HDO or MDO better for concrete forms?
For high-rotation or exposed glossy pours, start with HDO Premium or a Class 3 film-faced rung such as Pro Form. For a matte cast face, buyers often search MatteFace as MDO formwork plywood, with reuse up to 15 under site care. Write overlay, glue class, and reuse as up to N on the RFQ. Do not treat kraft-paper MDO and MatteFace as the same sheet.
How many times can HDO plywood be reused?
Write reuse as up to N, never as a guaranteed floor. Vinawood HDO Basic is up to 10; HDO Premium and Premium HD are up to 20. Site handling, sealed edges, and a proper release coat each pour decide whether those envelopes hold. Do not append a plus after the catalogue number.
Can you paint MDO plywood?
APA kraft-paper MDO is often used as a paint base for signs and exterior panels. MatteFace is a matte phenolic forming film for formwork only and is not a paint-grade sheet. If the job is a pour, specify MatteFace or HDO by finish. If the job is paint and signage, kraft-paper MDO is the usual search path.
Is MatteFace the same as MDO formwork plywood?
Keep the MDO search token on ranking pages. The formwork product name is MatteFace Plywood (MTF), a matte phenolic surface film rated up to 15 with edge sealing. Kraft-paper MDO is a different APA overlay class built for paint and signage. Soft bridge only: buyers often search for MatteFace as MDO formwork plywood.
Does a denser overlay mean phenolic Class 3?
No. Overlay density and face system are separate from core glue class. HDO and MatteFace sit on the overlay side of the RFQ. Phenolic Class 3 on Vinawood film-faced and HDO grades is PF core glue under EN 636-3. Form Extra is Superior Glue MUF under EN 636-2 and is not Class 3.
