the factors that cause fading

Restoration of composite decking can take a lot of time and effort.

Therefore, it makes much more sense to be proactive and ensure it does not get faded quickly.

To fix the issue and stop it from happening again, you must first identify the root cause of the fading of the composite surface. 

You may break down the fading of composite decking into four primary reasons: 

Extreme Heat

Constant exposure to light and heat is a major cause of decking losing its color, which is true for both wooden and composite decking.

When composites fade, they only lighten in tone. However, prolonged exposure to sunlight can weather wood to a silvery gray color. 

Low-Quality Material

Inadequate Maintenance

Simply use the homemade deck cleaner and spray generously on affected areas.

Then use a soft brush to get rid of any mold. Ensure you do not scrub vigorously, or it might damage the deck. 

Hard Water Staining
