Like rock salt, magnesium chloride also can melt ice. During winter, removing snow with a shovel can be a bit stressful for some. Using ice melt instead can dissolve the snow quickly. For those who have composite decking in their homes, snow on the deck can make the deck slippery. You might have considered laying magnesium chloride on your composite decking. Is magnesium chloride safe? Can you use magnesium chloride for composite decking?
How Magnesium Chloride Work on Composite Decking
Magnesium chloride is a naturally occurring compound that is flaky white. Some magnesium chloride can also look clear or transparent. The magnesium chloride is processed in the industry and used as ice melt on composite decking.
Ice melt is a substance used to dissolve snow on walkways or driveways. Ice melts works by lowering the freezing point of water, thereby melting ice. Magnesium chloride is an effective ice melt that dissolves ice easily. It works by absorbing moisture. If you place magnesium chloride on ice, it will start melting the ice very fast.
In addition, magnesium chloride also works to prevent the forming of ice on wood-plastic composite. If you place magnesium chloride on your deck before it starts snowing, it will prevent ice from forming. Homeowners who have decks can use ice melt to remove ice on the deck.
Is Magnesium Chloride Good For Composite Decking?
Like other ice melt like calcium chloride and rock salt, magnesium chloride is good for composite deckings. Magnesium chloride is not harsh; it is also less corrosive. It is less harmful to composite deckings if you use it moderately. Magnesium chloride is also less harmful to plants if you don’t overuse it.
In addition, magnesium chloride is environmentally friendly. It is good for use in the environment. Magnesium chloride is also less irritating to the skin. If your skin accidentally comes in contact with magnesium chloride, it might not irritate it.
Apart from that, magnesium chloride can melt ice quickly. It also differs from other ice melt in that it leaves little to no residue on your deck.
Precautions to Take When Using Magnesium Chloride on Composite Decking
When using ice melt like magnesium chloride on your deck, there are precautions you should take. If you follow these precautions, it will prevent your composite decking from early damage. Below are a few of the guidelines you need to follow if you want to apply ice melt on your composite decking.
Avoid Magnesium Chloride that Contains Colourants.
Firstly, when choosing magnesium chloride as an ice melt, do not choose a type containing colourants. A reason for it is because magnesium chloride that contains dye or colourants can stain your decking. The colourants in the ice melt can make your decking look ugly. It can create a slight discolouration to your composite decking, making it look less attractive.
You should avoid using any ice melt that may contain dye. Always ask well in stores before purchasing the ice melt. You should always go for a magnesium chloride ice melt that does not contain any trace of tint or dye.
Avoid Magnesium Chloride with Traction Grits.
If you want to apply magnesium chloride ice melt on your composite decking, do not use an ice melt that contains traction grits. Some ice melt contains traction grits like sand or wood dust. You should avoid using that kind of ice melt.
An ice melt with grits can disfigure your composite decking. It can also scratch the surface of your composite decking, thereby making it less attractive. In addition, deck owners should avoid using sand on wood-plastic composite either. Sand can be abrasive and scratch the surface of the composite decking.
Use Magnesium Chloride Moderately
When using magnesium chloride on composite decking, use a minimal amount. Do not apply too much to the composite decking. The magnesium chloride is effective even if you apply it in a little amount.
You can use magnesium chloride on composite decking. However, when using magnesium chloride, use it moderately. In addition, do not use magnesium chloride that contains traction grits or dye.
