Practical Notes

Ensure timber is properly seasoned as per IS 1141 to prevent warping or splitting of the table top after installation.

When using plywood, particle board, or blockboard as a core, veneering or lamination must be balanced on both faces (top and bottom) to prevent bowing.

Synthetic resin adhesives conforming to IS 848 should be used for better durability and moisture resistance.
