Low quality paint

Dirt build up
Painting on a dirty surface will typically lead to a peeling paint. Further, dirt build up over the deck surface can also affect the performance of your paint. Hard dirt particles can also scratch or cause openings into the paint coating where moisture can penetrate through to cause paint peeling.
Improper cleaning techniques can affect the paint on your deck. This has mainly to do with using incorrect cleaning products or improper use of a pressure washer when cleaning a wooden deck. High powered pressure washers are known to damage paint on wood similarly to harsh cleaning chemicals.
