Painting a damaged pool deck is not recommended if the substrate is crumbling, cracking, spalling, or otherwise actively deteriorating. Continuing deterioration will result in the paint also delaminating or flaking off the damaged surface. Minor damage such as chips or hairline cracks that are not actively deteriorating can often be repaired enough to paint over. A damaged pool deck with a lot of cracking and deterioration should be replaced for best results.

Staining a deck is typically less expensive upfront than painting. The cost to stain a deck professionally averages around $850, with most homeowners paying between $550 and $1,250, depending on the deck's size. A DIY staining project can cost less than $100. The cost to paint a deck ranges from $500 to $2,000. While the initial cost of staining is lower, it's important to consider long-term expenses. Paint can last up to 10 years, whereas stain needs to be reapplied every few years, which could lead to higher costs over time.

The best type of paint for concrete exterior surfaces like concrete porches, steps, or walkways is high-quality exterior-grade paint with strong weather resistance. Acrylic latex blends with tiny anti-slip particles will help create an anti-slip coating for your concrete porch. This type of paint will stand up best to the elements, especially rain, snow, and ice. An exterior epoxy will also help strengthen your concrete porch.

Painted decks typically require a new coat about once every ten years. In between new coats, it's best to maintain your deck by regularly removing debris, washing it down with non-abrasive cleaners, and staying ahead of structural issues, such as loose boards and rotting wood. In some cases, painting a small section of your deck affected by damage or the sun can lower your costs and workload.
