Quick Answers

What is HDO plywood used for?
HDO (High Density Overlay) plywood is primarily used for concrete formwork where a smooth, glossy concrete finish is required. It is also used for signage, architectural concrete, highway barriers, and industrial applications. The dense resin-impregnated overlay provides exceptional abrasion resistance and weatherproofing.
What is the difference between HDO and MDO plywood?
HDO plywood has a denser, harder overlay that produces glossy concrete finishes and withstands more reuse cycles. MDO plywood has a lighter overlay that produces matte finishes and is more affordable. HDO is preferred for architectural concrete and high-reuse formwork, while MDO suits standard construction and signage applications.
How many times can HDO plywood be reused for formwork?
Premium HDO plywood panels can achieve up to 25 reuses when properly maintained with release agents and stored correctly between pours. The number of reuses depends on the overlay density, core quality, and how carefully panels are handled, cleaned, and stored on site.
Is HDO plywood waterproof?
HDO plywood is highly water-resistant thanks to its resin-saturated fiber overlay and WBP (weather and boil proof) adhesive. While no wood product is fully waterproof indefinitely, HDO panels resist moisture penetration far better than standard plywood and maintain structural integrity through repeated wet-dry cycles on construction sites.
