MaintenancMaintenance of plywood
Avoid dropping plywood and dragging it over the ground.
Plywood sheets, intended for assembling of the formwork on the following floors, should be arranged to be hoisted by a crane to the floor above.
Fill all holes, made in the course of installation works, with a silicone-based adhesive to prevent penetration of moisture (swelling).
After the formwork is dismantled, inspect the plywood. Remove any excess concrete. Do not use severely deformed sheets for further works. If damages are minor, use the sheets for non-standard elements
When cutting plywood, protect flat ends with paint. SVEZA recommends to use the acrylic paint TEKNOS Teknol JRL (Finland) or a sealant to prevent penetration of moisture (swelling).
It is convenient to control the correct installation of reinforcement by the Engineering Supervision. Properly installed reinforcement guarantees high quality of performed works.
Cut a piece along the markup line
Put reinforcement elements over the plywood, focusing on markup lines. This will parallel cutting
If the line of the potential cut does not match the markup line, use the blade on the saw panel. Put the blade in the cutting point. Use the ruler on the saw blade and the closest markup line. When cutting, a division of the ruler on the saw blade should always match the line on the plywood
Put plastic chairs in required places. Determine the distance between chairs by grid cells.
Measure the size you want by grid cells or by using a tape.
If plywood gets wet, let it dry naturally.
If plywood is temporarily stored outdoors, cover it with an impermeable material. Protect flat ends from moisture. Pallets, wooden strips or wooden bars-pads must be dry to avoid leaving marks on the film.
Store individual sheets on a stable basis over the ground. Use pallets, wooden strips or wooden bars-pads to avoid sagging of plywood sheets
During long-term storage, cut or remove all package tapes. This will prevent appearance of marks on the top and bottom sheets of the packs.
Plywood should be stored in a horizontal position, in the packs on pallets, wooden strips or wooden bars-pads (thickness – not less than 50 mm, length – not less than the width of a pack, without overhanging).
Storage temperature should be from -40° to +50° C. Relative humidity must not exceed 80%.
Store plywood in a closed room.
Avoid damaging plywood sheets with loader pitchforks.
Metal straps, hooks or chains must not come into contact with sheets of plywood. They can touch only plywood side facings and covers of the packs.
Do not push the packs of plywood with loader pitchforks.
When handling plywood, avoid breaking the package tapes.
Protect plywood from moisture during transportation
Avoid damaging the packs and breaking the package tapese of plywood
