Water or liquid damage has the potential to ruin a wooden coffee table. When a spillage occurs and water is left on the wood for a long time, the table absorbs it, causing the wood to swell. If your large square wood coffee table becomes water damaged, there are ways you can treat it.
Start by sanding the affected area until it becomes smooth and looks even. You’ll then need to sand the rest of the table to even it out. If the water damage still hasn’t disappeared and the table isn’t entirely even, mix water and bleach and scrub the table, making sure you attend to the affected area most.
Allow the table to dry and sand again to achieve a smooth finish. For extra protection, apply furniture oil onto the table using a rag. Let it dry before you place anything on the table.
