The Ultimate Guide to Deck Waterproofing Membrane

A deck waterproofing membrane is a coating that protects the deck from water damage. Deck coatings are made up of various materials, and waterproofing membranes are just one type. They have been used for years to protect decks from being damaged by rain or snowmelt. They work because they create an impenetrable barrier between the deck boards and any water underneath the deck surface so it will not get through to cause damage.

The deck waterproofing membrane is a popular and effective way to protect your deck from water damage. It’s important to know that deck waterproofing membrane is not the same as deck paint, but it does protect against water intrusion as deck paint does.

These membranes are typically made of rubber or plastic materials that don’t sag or crack once applied. They come in rolls that you unroll over the deck surface and then use a roller or brush to press them into the gaps between the deck boards.
Once applied, it will create a watertight seal that prevents rain or snowmelt from seeping underneath your deck and causing damage.
