How Wood and Composite Decks React to Ice Melt

Because ice melt products often contain harsh chemicals like sodium chloride, they can cause significant damage to both wood and composite decks over time.
When you apply ice melt, here’s what can happen:
Wood decks absorb moisture drawn by salts, causing swelling, cracking, and warping.
Moisture absorbed by wood decks from salts leads to swelling, cracking, and warping over time.
Composite decks may show surface discoloration and fading, especially from prolonged exposure.
Repeated use of harsh ice melts weakens wood fibers, reducing deck lifespan.
Metal fasteners and components on both deck types can corrode, risking structural integrity.
To reduce damage, opt for ice melt products containing magnesium chloride or calcium chloride, which are gentler on wood and composite surfaces.
Using the right product helps you protect your deck while safely managing ice buildup.
