KRONOPLY quicklyboard is a versatile building panel and formwork board for basic concreting jobs. It boasts outstanding bending properties, and its ContiFinish^® surface both inhibits penetration of moisture and ensures easy stripping.

Economic and Easy to Use

KRONOPLY quicklyboard lends itself to all formwork applications, and can also be easily cut to size for structural uses and construction site fences. It is competitive and economic, and is simple to saw, cut and nail. Its very good nail and screw holding power makes sure that it stays securely fastened to any substrate. Thanks to the ContiRoll® technology used to produce KRONOPLY quicklyboard, swelling is negligible. The grained surface of the boards leaves an attractive imprint on concrete. It is an economic alternative to conventional plywood for formwork.

Laying and Boarding

• When laid closely with butt joints in interior walls, leave room for expansion where the boards adjoin other structures.
• The storey-high formats are produced with a slightly reduced width (of 1247 mm) to allow for expansion.

Coating and Varnishing

• KRONOPLY OSB with a ContiFinish^® surface may be coated with a solvent-containing PU (DD) or synthetic-resin varnish.
• Sanded surfaces may be coated like normal wood (e.g. with varnishes, paints, oils, waxes and glazes).
• It is advisable to apply at least three coats, sanding after the first one.
• Application of at least three coats is recommended.
• The only way to achieve an absolutely smooth surface is to apply filler.

Transport and Handling

• Take steps to prevent the boards, and especially the unprotected edges, from absorbing large amounts of moisture during transport and installation. Be careful not to damage the edges when lifting, moving and stacking boards (this applies especially to tongue-and- groove boards).
• Check against the labels or producer’s documentation on-site to make sure that the following are correct: thickness, approved utilisation class, surface (sanded or ContiFinish®) and edge type (square-edged or tongue-and-groove).
• During installation, boards may be briefly leaned against a solid structure at a 70° angle.
• Always carry individual boards in an upright (vertical) position.

Storage

• Protect boards from exposure to significant moisture or very high relative humidity.
• Prevent direct contact of the boards with the floor. ■ Only store outdoors temporarily, and if unavoidable cover stacks with watertight but water-vapour-permeable tarpaulins.
• Always stack boards horizontally on pallets and wooden supports (spaced no more than 600 mm apart).
• Align wooden supports precisely with one another and parallel to the shorter side of the boards.
• Lay the boards so their edges line up (with a maximum overhang of 15 mm).

Acclimatisation

• Precondition boards prior to installation.
• Store boards for about three days under the same climatic conditions that prevail at the installation site.
• This adjustment to the ambient moisture at the installation site will prevent excessive shrinkage or swelling.

Sawing, Milling, Sanding and Drilling

• KRONOPLY OSB can be sanded, sawn, milled and drilled just like solid wood and using all of the same tools.

Nailing, Stapling, Screwing and Gluing

• KRONOPLY OSB can be attached to wooden studs and rafters using screws, nails or staples.
• Use in accordance with the official approvals and standards (Z-9.1-618, Z-9.1-503 and DIN 1052 in Germany as well as EN 1995-1-1 (EC 5)).
• Additionally bond or glue tongue-and-groove joints.
