What is Weatherproofing a Table?

A ping pong table is essentially a wood slab with a rubber cushion beneath it. It must be kept from moisture, which could ruin the cushions or the table. You want to be able to play ping pong on the table at all times, but you want to keep rainwater from getting inside.

Weatherproofing a ping pong table is pretty simple, though. If you’ve got the money and want to spend it, you could have a table professionally made.

What’s the Best Waterproofing Solution Ping Pong Table?

Waterproofing is making any type of material nonporous and impermeable to the elements (air and water). To do this, an application of polyurethane is used to seal the seams of all of the joints in the table tennis tables and the entire table itself. This prevents any water from ever coming inside the table.

This blog post will cover some basic information on polyurethane and why it is one of the best ways to waterproof a ping pong table. It’s important to know that polyurethane is used to keep out the elements and act as a sealant.

Why is Polyurethane So Great for Weatherproofing Ping Pong Tables?

Polyurethane Sealers for Weatherproofing

Polyurethane is so great for weatherproofing ping pong tables because of its resistance to chemicals, moisture, and most other things that would get to it. Polyurethane is also odorless, non-toxic, and easy to clean.

Once the polyurethane has cured and hardened, scrub it with a soap and water solution, then let it air dry. It’s amazing stuff!

A quick note on polyurethane…

When applying polyurethane, you must be sure that no bare skin is exposed. If you apply it to the skin, it can cause dermatitis. When applying the polyurethane, you want to ensure you don’t leave any bare skin around the edges or any visible open seams. If you do that, it will prevent the polyurethane from curing properly and sealing the surface properly.

To waterproof a ping pong table, you need to apply polyurethane to the surfaces of the table itself and all of the seams. Remember to work on an un-mopped area so there is less chance of the polyurethane leaving a residue on the floor.

Application Tips:

Remember to apply polyurethane to a flat, solid surface like concrete or plywood. Applying it to carpet, furniture, or any other object will spread, and you’ll get a thicker application of polyurethane.

  4. Allow the table to dry for about an hour, and then apply another coat of polyurethane using the same process. Once the table is dry, let it completely air-dry overnight.

How Does Waterproofing Affect Your Ping Pong Table?

Polyurethane Sealants, while not waterproof, can help protect against scratches and general wear and tear and keep out dirt and water. In addition, using multiple layers and applying the polyurethane sealant evenly helps the top layer remain intact and can act as a barrier between the surface and any spills.

Sanding the table also promotes adhesion between layers and helps prevent dust accumulation.

Can you leave an outdoor ping pong table in the rain?

Is a ping pong table waterproof?
