As a finishing touch, I coat the entire table with a home-made whiting-based coating. Here's how to make this coating: 9 parts whiting, 6 parts of PVA glue (white wood glue), 3 parts water, 1 spoonful of linseed oil. Next, I paint the table (it can also be covered in hand-made paper) but I prefer paint. To protect and waterproof it, I coat it with a polyurethane aqueous phase varnish (varnish used on parquet floors, for example). The table is ready. It's protected if it gets splashed with water and you can set heavy objects on it, as this table can bear up to 100 kg per m2 (about 20lb per sq ft).
