SAFETY

Care and Handling of Plywood

General Storing and Handling

Plywood, like any other panel product, requires proper handling and storage. Despite its sturdy cross-laminated construction, face veneers, panel edges and panel corners are vulnerable to damage and should always be protected.

Plywood is manufactured at a low moisture content and while small changes in moisture content will not appreciably affect its dimensions, large changes should be avoided since they may encourage checking of the face veneer with consequent impairment of its qualities as a paint base. It is good practice to store plywood which is to be used for interior finish under conditions that approximate those it will experience in service.

 

Points to watch when handling plywood are:

1. Store plywood panels flat and level.

2. Keep finish faces inward and cover stacks to protect from bumping and abrasion.

3. Protect panel edges and corners. This is especially important with tongue and groove plywood.

4. Carry panels on edge (always being careful not to damage faces, edges and corners).

5. When plywood is used as a finishing material, deliver to job-site at the last possible moment.

6. Protect panels from sunlight, water or excessive humidity.

 

Storage and Handling for Easy T&G Panels (Floor & Roof Profiles)

The EASY T&G profiles are sturdily built and designed to engage even when wet. But dry, undamaged panels install faster and easier, so maximize the time you can save by following these suggestions on the job site:

1. Cover plywood bundles with plastic or tarp

2. Use three supports as dunnage to prevent sagging

3. Do not mix CANPLY EASY T&G with other T&G's

Care & Handling Plywood for Concrete Forms

Cleaning

Proper supervision of forming operations on the job site should extend to the cleaning and repair of forms. Plywood forms, in common with all other types, should be cleaned immediately after stripping. Concrete particles may be removed by using a wide blunt blade, straw broom or burlap sacking. Many contractors use a power-driven nylon brush. There are also several proprietary solutions available for softening concrete adhereing to the plywood.

Handling

It is generally acknowleged that the greatest damage to forms occurs during the various handling operations. Care should be taken to prevent chipping, denting and damage to panel edges. Thorough planning of the whole forming operation will keep handing to a minimum. In the interests of speed and efficiency, mechanical handling devices should be used whenever possible.

 

Care & Handling Decorative Plywood

The importance of proper care and storage of plywood prior to finishing cannot be over-emphasized. Plywood which will become part of the decorative scheme should be handled as carefully as trim material, sidings or other quality finish products. Many early paint failures can be traced directly to improper handling and storage. Moisture can enter the panel prior to finishing during storage in damp or humid areas, or because of delay in priming the plywood after installation, or because of omission of the edge seal. (The latter two are important only if the panels are to be exposed outdoors.)


 

 

Repairing

It is recommended that plywood forms be inspected after each use and repairs such as patching or renailing carried out as required.
Plywood forms should be clean and dry before repairs are made. Where the grade of plywood and the type of form are suitable, the plywood may be reversed. Small splits and depressions can be filled with a suitable patching compound sanded flush.


Unwanted holes through the plywood may be patched by:

1. Driving a wooden plug in tightly and sanding
flush.

2. Backing up the hole with scrap wood, filling
with patching compound and sanding flush.

3. Driving a metal patching disc into the plywood face.

Experience has shown that even if a plywood form is damaged beyond economical repair,
the plywood itself can be salvaged and usefully re-employed in numerous fields, for example as stiffening gussets on new formwork as rough foundation formwork, and in those areas where formwork is difficult to remove and must be left in place.







Thus all panels should be stored in a cool,
dry place out of the sunlight. They should be well covered if left outdoors during construction. The prime coat and edge seal for panels intended for exterior exposure should be applied as soon as possible. Water repellent coatings do not serve as a substitute for the prime paint coat. They will, however, retard moisture pickup until the prime coat can be applied
and, providing they do not have a wax base, should provide an improved
surface for painting.
