JITONG® GUIDE TO GOOD SITE PRACTICE
-----Careful Site Handling, Longer Service Life.
Before use
• Protect the panels from contact with water and direct sunlight by storing in a building or by covering with a suitable waterproof cover.
• Store panels flat on level ground, well clear of mud or standing water, and away from any risk of contact with vehicles or machinery.
• Avoid storing in very hot and dry places which may lead to panel distortion.
• If the panels are to be stored on site for more than a few days, the outer packing and strapping should be removed.
• CAUTION: Once the strapping has been removed the boards should not be moved further on site using mechanical handling equipment, as overlaid panels are extremely slippery.
Form preparation
• Coated Jitong-Form plywood panels are delivered with all 4 edges protected with edge paint to help reduce moisture penetration. If panels are cut or drilled all cut edges and holes must be painted immediately with a suitable acrylic based paint.
• To give the best results, we recommend that the plywood should be fastened from the formwork support members into the back of the panel.
• Formwork panels should be oiled before each and every use regardless of the storage conditions or interval between pours.
• The selection of the most suitable type of release agent for the type of overlay (e.g. phenol film or MDO) will ensure cleaner striking of the forms and more reuses. The quality of the release agent may also affect the quality or appearance of the concrete finish. Please follow the instructions of the release agent supplier regarding application rate.
After Use
• Clean the plywood panel carefully, dry and re-oil immediately. Any forms not cleaned immediately after use are likely to be damaged when attempts are made to remove fully cured concrete from the forming face (panel surface).
• Take care not to damage the panel surface when cleaning the form of residues of concrete. We recommend plastic or nylon tools when cleaning, metal brushes or high-pressure washers should not be used.
• Store the forms with the face away from the sun as exposure can lead to rapid loss of moisture from the face veneer and damage to the overlay.
• Repair small scratches with a suitable mastic.
• Fill deeper scratches, nail or screw holes with mastic or epoxy filler. Wooden insert systems are available for larger repairs.
• After use please choose a suitable recycling option for your JiTong-Form panels. They can for example be chipped and utilized in bio energy production.
