Sturdy and durable, composite decking is a great place to spend happy hour with friends, cook a big meal for your family, or enjoy the sunshine in your own backyard paradise. Keep reading this blog to learn how to fix a faded composite deck.

Avoiding Problems is the Best Way to Fix Them

Even if your composite decking boards have faded, there are steps you can take to fix the problem. However, fading is not inevitable, and you can avoid it by regularly cleaning the dirt and debris that builds up on your composite decking.

Many things can cause composite decking to fade over time. And some of these things you may not even realize. Some of the main reasons why composite decking boards fade are usually due to the following three reasons:

  • The quality of the composite decking used
  • The type of cleaning products you choose to use
  • Whether or not it has been exposed to prolonged sunlight

Why Does Composite Decking Fade?

It is important to understand why the surface of composite decking boards fades. This will enable you to solve the problem and prevent it from happening again. There are four main reasons why composite decking fades:


Wrong cleaning products

Composite decking like Trex and COOWIN are made from a mixture of materials. Cleaning these decking trim materials is best done with product-specific cleaners. To avoid fading of composite decking boards, do not use chlorine bleach, wire brushes, or excessive pressure washing.

Improper Maintenance

Composite decking discoloration is usually the result of improper maintenance. However, composite decking does not require regular maintenance and upkeep work. But just like any other part of your home, you need to keep it clean and tidy.

Over time, the accumulation of leaves, dust, and other debris can lead to mold and rot. Regular cleaning of composite decking boards helps prevent them from fading. Typically, thorough cleaning of composite decking twice a year is all that is needed to keep it looking great.

Sun Damage

In some areas, the summer sun can be really hot. If your yard faces south or your traditional wood deck is constantly exposed to the sun. Then over time, just the wood deck will fade and warp.

On the other hand, composite decking is not as susceptible to sun damage as solid wood decking. High-quality composite decking won’t fade as a result either, such as brands like Trex and COOWIN. If you live in a hot area, the recommendation is for you to choose light-colored composite decking boards.


Low-quality Composite Decking Material

Composite decking materials are made from recycled plastic, wood fibers, and other mixes. If your deck is built with low-quality composite decking materials, it may quickly develop fading and warping. Common manufacturers of composite decking are Trex, COOWIN, Timbertech, and others.

How to Keep Your Deck Clean

In most cases, keeping your composite decking in good condition is enough to prevent it from fading. Even if the deck has faded, the first thing to do to bring it back to life is to clean it well. After a storm is the best time to clean the surface of composite decking boards. This is because debris and dirt are more likely to adhere to the surface of the deck.

But don’t worry, to keep your composite decking clean, you don’t need to spend a lot of money on cleaning products or tools. In fact, be very careful when using a power washer as too much pressure may damage the deck surface. Many people don’t like to use a pressure washer on composite decking because the composite decking material is more susceptible to damage than wood.


How to Clean Composite Decking?

  1. First, clean the deck by moving all furniture out of the way, leaving a void. Remove any large pieces of debris by hand or with a broom. Then, spray the deck surface with water from a hose.
  2. Clean the deck using one gallon of water, one cup of baking soda, and one-half cup of apple cider vinegar or white wine vinegar. Be careful to cover the entire composite decking with the solution when spraying the cleaning solution. you can use a pressure washer with a pressure of no more than 3100 PSI, or use a soft bristle brush.
  3. Rinse off with clean, warm water, making sure not to leave any puddles. This will remove all the foam and prevent mold growth.

How to Remove Stains from Composite Decking

If you don’t keep your outdoor living areas clean, they will get stained. These tips will help you remove stains from composite decking boards.

Stains Caused by Mold

The mold itself does not grow on composite decking. However, under the right conditions, mold can grow if you don’t take care of it. Pollen, dust, leaves, and warm, humid air are the main causes of mold. As long as you follow the cleaning tips above, mold will not be a problem.


Hard Water

If hard water is used to clean composite decking, a mineral layer may form on the surface of the deck, making the deck look like it is fading. Suppose hard water must be used to clean the surface of the composite decking. In that case, it will be necessary to either manually dry the surface of the decking or add water softening tablets to the water to clean the water used.

Rubber Mats

Rubber mats are good for health and safety, but the chemicals in them may change the color of the composite deck. If you find this to be the case, clean the deck properly, throw away the rubber mats, and replace them with new ones made of a different material.

Cleaning Snow and Ice

Although snow and ice will not damage composite decking, extra care should be taken when removing it. Always use a plastic shovel when breaking up ice and never use anything other than calcium chloride or rock salt. Metal tools and rough chemicals can harm the soft surface of composite decking boards and make them look less attractive.

Power Wash Composite-Decking


Remember, even though composite decking is the best in terms of maintenance, appearance, and sturdiness, you still have to be careful with it.
