Composite decking has become an increasingly popular choice for homeowners due to its durability, low maintenance needs, and attractive appearance. However, when winter rolls around, many people are unsure about how to properly care for their composite decks without damaging them. A common question that arises is whether rock salt or ice melt can be safely used on a composite deck. In this article, we will delve into this topic and provide you with some valuable information.
Understanding Composite Decking
Before we discuss the use of rock salt or ice melt, it’s essential to have a basic understanding of composite decking and its composition. Composite decking is made from a combination of wood fibers, recycled plastics, and binding agents. This composition gives the decking boards the appearance of real wood while offering superior resistance to moisture, rot, and insects.
Though composite decking is highly resistant to the environmental elements, it is not impervious to damage. Like any outdoor surface, it requires regular maintenance to prolong its lifespan and overall appearance.
The Concerns with Rock Salt and Ice Melt
Rock salt and ice melt are commonly used to melt ice and snow on various surfaces during winter. However, when it comes to composite decking, caution should be exercised due to a few concerns.
- Potential Damage: Rock salt, which is primarily sodium chloride, can potentially seep into the composite material and cause damage over time. The high salt content can corrode the binding agents that hold the decking together, leading to discoloration, warping, and even structural damage.
- Color Fading: Another concern is color fading. Rock salt and ice melt can cause the color pigments in composite decking to fade and lose their vibrancy over time, leaving the deck looking lackluster and aged.
Alternative Winter Care Strategies
Fortunately, there are alternative strategies to keep your composite deck free from ice and snow buildup during the winter months.
- Mechanical Snow Removal: The first line of defense is to mechanically remove snow from your composite deck using a plastic shovel or a snow blower. Be sure to avoid metal shovels, as they can cause scratches or gouges on the surface of the deck.
- Power Washing: If ice has already formed and cannot be easily removed, opt for using a power washer with a low-pressure setting to melt and remove the ice. Avoid excessive pressure or using hot water, as these can potentially damage the deck.
- Warm Water and Gentle Cleansers: If you need to remove light ice or snow residue, using a mixture of warm water and a gentle cleanser specifically designed for composite decking can be an effective and safe method. Be sure to follow the manufacturer’s instructions when using any cleaning products.
- Preventive Measures: To minimize the need for ice and snow removal in the first place, consider using a non-stick coating or a high-quality sealer on your composite deck before the winter season. These products can help prevent snow and ice from bonding to the surface, making it easier to remove them.
While rock salt and ice melt may be effective in melting ice and snow on other surfaces, they should be avoided on composite decking. The potential damage and color fading outweigh any short-term conveniences. Instead, opt for mechanical snow removal, power washing with caution, gentle cleansers, and preventive measures to ensure the longevity and appearance of your composite deck. By following these strategies, you can enjoy a clear and beautiful deck all winter long without compromising its integrity.
