Sharp Ply Calibrated Sheathing Sheet

C

alibrated sheathing sheet is
ultimate in plywood having
excellent physical and mechanical
properties. The rigid laminated surface
not only prevents moisture absorption
but also ensure excellent abrasion
resistance in aggressive conditions and
smooth finish to concrete formwork. It

has been designed to suit any and every

application needs of construction

industry where durability, versatility,

high bending strength, rigidity,

stability, accuracy and tolerance to

humidity parameters of performance

value are critical.

Tips for optimum utilisation of

shuttering plywood

Protect from weather: Store the

formworks and the loose formwork

panels against sun and rain.

Use standard tool: Film faced plywood

can be cut shaped and drilled using

standard wood working stools.

Seal edges and holes: Seal the

resulting raw edges and holes with

suitable water-resistant paint.

Oil panels before use: A suitable

approved release agent must be used

to ensure cleaner and easier striking

and also more re-users.

Back face fastening: To achieve the

best results, it is recommended that

the plywood should be fastened to the

formwork support members from the

back of the panel.

Avoid falling from height: Plywood

panels should be handled very

carefully when moving high above the

ground to prevent damages.

Clean after use: Plywood panels should be

cleaned carefully with water or damaging

the stream after use. Avoid damaging

the panels surface when cleaning the

concrete residues. n
