HDO Concrete Form Plywood","description":"\u003cp\u003eHigh Density Overlay (HDO) form panel is a plywood sheet faced on both sides with a thermosetting resin-impregnated fiber overlay bonded to the veneer under heat and pressure. The overlay gives the panel a hard, nearly non-porous surface that releases cleanly from cured concrete and leaves a smooth as-cast finish with little or no patching.\u003c\/p\u003e\n\u003cp\u003ePanels of this type are built with exterior-grade adhesive and are intended for repeated use in wall, column and slab formwork. The dense face resists the abrasion of pouring and vibrating, resists absorption of water from the mix, and can be cleaned and re-oiled between pours, so a single panel typically serves many cycles before the overlay is worn through.\u003c\/p\u003e\n\u003cp\u003eHDO is the higher-grade choice among overlaid form panels, used where the concrete will be left exposed and the form marks will be seen. Cut edges should be sealed with an edge sealer to keep moisture out of the core.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eResin-impregnated high density overlay bonded to both faces\u003c\/li\u003e\n\u003cli\u003eHard, low-porosity surface releases cleanly and produces a smooth as-cast concrete finish\u003c\/li\u003e\n\u003cli\u003eExterior-type adhesive bond for wet-use formwork service\u003c\/li\u003e\n\u003cli\u003eDesigned for multiple pours; faces can be cleaned and re-oiled between uses\u003c\/li\u003e\n\u003cli\u003eStandard 4 ft. x 8 ft. panel format for framing on conventional form studs and walers\u003c\/li\u003e\n\u003cli\u003e3\/4 in. thickness for greater stiffness and reduced deflection between supports\u003c\/li\u003e\n\u003cli\u003eCuts and drills with standard carbide-tipped woodworking tools; cut edges take an edge sealer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eArchitectural concrete wall and column forms where the finish is left exposed\u003c\/li\u003e\n\u003cli\u003eFoundation and retaining wall formwork\u003c\/li\u003e\n\u003cli\u003eSlab edge forms, curbs and pier caps\u003c\/li\u003e\n\u003cli\u003eBridge, parapet and other civil concrete forming\u003c\/li\u003e\n\u003cli\u003eReusable gang forms and job-built form panels\u003c\/li\u003e\n\u003cli\u003ePrecast concrete molds and casting beds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e HDO concrete form plywood panel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverlay:\u003c\/strong\u003e High Density Overlay (HDO), both faces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Veneer plywood core with resin-impregnated fiber overlay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Thickness:\u003c\/strong\u003e 3\/4 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Size:\u003c\/strong\u003e 4 ft. x 8 ft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type:\u003c\/strong\u003e Exterior\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended Use:\u003c\/strong\u003e Reusable concrete formwork\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As:\u003c\/strong\u003e Each panel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"product-specs\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e3\/4\" x 4' x 8'\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eConcrete\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"ARCH Building Supply","offers":[{"title":"Default Title","offer_id":55048725266771,"sku":"HDO","price":51.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/arch-placeholder-coming-soon_6caf25f6-778c-4e0e-8c3e-4dea15a8974d.webp?v=1790259803","url":"https:\/\/arch-9365.myshopify.com\/zh\/products\/3-4-in-x-4-ft-x-8-ft-hdo-concrete-form-plywood-hdo","provider":"ARCH","version":"1.0","type":"link"}
