Why is the composite deck turning white

Before you learn how to fix a faded deck, find out what causes composite materials to fade. This will not only help you find the right solution, but it is also very important for future prevention to prevent the deck from fading again.

Sunburn

Regardless of the material, fading can occur if exposed to the sun for an extended period of time. Constant heat and sunlight can damage the surface coating of the deck, but when composite materials fade, only a very light shade is formed. With traditional wood, severe fading and discoloration can occur. Prolonged direct sunlight can also cause the composite decking surface to expand and contract. Which can put pressure on the material and cause cracking and warping of the deck.

Quality

Generally speaking, the poorer the quality of the decking material, the more likely it is to have fading problems. If you choose a cheaper deck, then your deck is likely to have fading and whitening problems. Early composite decking was more prone to fading, but as technology evolved, the quality of composite decks has gotten better.

Improper maintenance

Maintenance-free is one of the important advantages of composite decking, however, this does not mean that it does not require any maintenance. You must clean your deck regularly to keep the deck surface clean enough.

This is because dust, leaves, and debris may accumulate on the surface of your deck, leading to the growth of mold and algae. This can cause your composite deck boards to rot, crack or even fade. Therefore, the more maintenance and cleaning you make to your deck, the fewer problems your deck will have.

Substance damage

Using the wrong items to clean your deck can also cause fading of composite materials. Some cleaners with chemicals can damage your deck’s surface, leading to fading.

In addition to causing fading, it can also damage your entire deck with cracking and corrosion. Also, using some metal brushes and pressure washers may also damage your deck, which can cause fading. So before you clean your composite decking, make sure you know and follow some rules of cleaning.

Static electricity

Because of the special composition of composite decking, static electricity can sometimes be generated. When the deck comes in contact with shoes or furniture, friction occurs which leads to static electricity. Static electricity attracts dust and dirt, which can lead to a buildup of dirt, which can cause your deck to fade and discolor.

Humidity

Composite decking is highly resistant to moisture, however at some point moisture can affect your deck. Standing water and moisture that has not been cleaned up for a long time can lead to mold and algae growth. Leaving your deck with fading and discoloration problems. In severe cases, this can lead to cracking, rotting, and breaking of the deck.
