Merbok Shutterboard

Merbok Shutterboard is a specially formulated composite panel that has been developed for concrete shuttering and formwork applications. The panel is finished with a phenolic overlay and edge sealed.

Merbok Shutterboard’s ease of use in terms of workability provides contractors the opportunity to provide customers with improved quality and reduced job times.

Innovative Concrete Formwork

Merbok Shutterboard is a specially formulated composite panel that has been developed for concrete shuttering and formwork applications. The panel is finished with a phenolic overlay and edge sealed.

Merbok Shutterboard's ease of use in terms of workability provides contractors the opportunity to provide customers with improved quality and reduced job times.

The specially formulated phenolic based coating is processed under high temperature and pressure making it a smooth, water resistant surface with excellent release qualities. The smooth surface eliminates the telegraphing of surface defects normally found in traditional materials thereby reducing the time taken to finish the surface in subsequent processes such as plastering.

Merbok Shutterboard is ideal for all types of formwork and excels where a superior surface finish and complex forms are required.

STANDARD PRODUCTS

Merbok Shutterboard is available in thickness of 15mm and 18mm and in a panel size of 2440mm x 1220mm. Please contact Merbok to discuss your specific requirements.

STORING AND HANDLING MERBOK SHUTTERBOARD

Although Merbok Shutterboard is sealed on all edges with a special sealant, panels should be stored undercover in a dry, well ventilated area and when delivered to worksites covered with plastic or tarpaulin sheets until use. Sheets should be stored flat with uniformly and vertically aligned support bearers which should be placed evenly at 600 centres. All packing materials should be disposed of thoughtfully.

WORKING WITH MERBOK SHUTTERBOARD

Merbok Shutterboard can be cut, machined, filed and drilled with commonly available woodworking equipment. The best cutting can be obtained using 72-96 teeth sawblades. It is recommended that appropriate sized pilot holes should be drilled prior to nailing or screwing. When cutting or machining Merbok Shutterboard, suitable dust makes should be worn and the work environment well ventilated. Panels should be wiped down with a damp cloth after use prior to storing in the manner recommended above, and reuse.

When Merbok Shutterboards are used in horizontal applications and exposed to heat through direct sunlight, uneven tensions can be caused in the board resulting in an uneven surface. Although the flatness is normally restored as soon as the board cools and the structure of Shutterboard remains unaffected. Merbok recommends that Merbok Shutterboard is adequately nailed / screwed to the supporting timber framework which should be of a suitable hardwood material which would prevent the ‘pulling out’ of nails due to thermal stresses. Since the safe use of Merbok Shutterboard depends on the application and site conditions, the contractor’s.
