Use coasters and trivets to keep moisture and heat off of your table. Even though it is waterproof and sealed properly, it may still be susceptible to rings and heat damage. Wipe up spills immediately to prevent moisture penetration.

A dining room table is often a centerpiece in your home. It is the gathering place for wonderful meals. As a result, it must be able to withstand spills, sweating glasses and the vapors it is exposed to. Waterproofing your table is an easy task that will preserve the luster and beauty of your table.

How to Waterproof a Dining Table

Step 1

Examine your dining room table for any deformities or scratches that you want to repair. If your table already has a polyurethane finish on with no damage, you will not need to sand it and can go automatically to Step 5.

Step 2

Sand the existing finish off and sand out any blemishes and scratches that exist.

Step 3

Wipe down the table with a dry clean cloth to remove any dust from the surface.

Step 4

Paint the polyurethane finish/paint on the table. Apply two to three coats and allow this to dry. Look at the table from different angles and with bright lighting to make sure you are covering the table evenly. Allow this to dry for several hours.

Step 5

Paint the waterproof sealer on the table. Allow this to dry overnight.
