The table is a bean shaped hollow structure made of two 4mm hardboard panels and has a convex siding. The top surface and the sidings are coated seamlessly.
It's 40mm thick and about 1.5 square meters in area, and I don't need to process the bottom side, just the upper surface and the sidings.
The table has few holes (up to 7mm in diameter) and many scratches all over the surface and sidings (up to 2mm deep).
I need to repair it and hopefully make it better then buying a new one.
I want it to be opaque non-glossy dark blue color.
Also I want it inflammable, safe for food, washable and kind of resistant to kid's technical experiments.
What kind and amount of coating, dye or other materials to use, what tools do I need, and what is the process?
