How to Choose Waterproof Deck Coatings: A Homeowner’s Guide

24th May 2023

The average roof will collect over 600 gallons of water with just one inch of rainfall. One-eighth of an inch of rain is enough to fill a 54-gallon rain barrel. But it’s not just your roof that gets pummeled with water during a rainstorm — your deck does, too. That’s why many homeowners have been investing in one of the many types of do-it-yourself waterproof deck membranes to provide an additional moisture-resistant barrier. Here’s what you need to know about choosing the right do it yourself waterproof deck membrane for your waterproofing needs.

Consider Deck Material

First, think about your deck’s material before deciding on a waterproof decking barrier. There’s wood, concrete, standard plywood, and many other materials that may react differently based on the ingredients in different variations of residential and commercial deck sealant. You don’t want to make an investment in a waterproof coating just to find out that it’s not intended for your deck’s surface and could even cause damage to it.

Determine Level of Waterproofing Needed

When considering how much moisture protection your deck needs, first think about how often you use it. Decks that are walked on more often may require an extra level of protection that lasts longer so it doesn’t wear down prematurely and cause damage. Similarly, you should think about the area you live and how often it rains. When in doubt, however, it’s always better to be safe than sorry and invest in a multi-layer waterproof coating solution.

Compare Prices and Providers

Finally, start shopping around at local providers and explore their current selections. You want to choose a provider that offers a wide range of products while remaining at a price point you can afford. One great option is EPDM, an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings; its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. The provider you choose should be knowledgeable and able to help you make the right decision.

Of all homes with basements, over 98% will experience some type of water damage. Investing in DIY waterproofing systems can help keep your home protected. For more information about residential and commercial waterproofing products, contact Ames Research Laboratories Inc.
