When your pool surface starts looking rough, stained, or worn, you have two main options: an acid wash or a full resurface. Understanding the difference helps you make the right choice and avoid spending more than necessary.

Acid Wash: The Surface Refresh

An acid wash strips a thin layer of plaster to reveal the clean surface underneath. It's essentially a deep clean for your pool's interior.

When Acid Wash Is the Right Choice

•Surface staining from minerals, algae, or chemicals

•General discoloration and dinginess

•Light calcium scale deposits

•Pool hasn't been acid washed more than 3-4 times previously

•Plaster is still structurally sound with adequate thickness

Acid Wash Pros

•Significantly less expensive than resurfacing

•Completed in 1-2 days

•Pool back in service within 48 hours

•Dramatic visual improvement

Acid Wash Cons

•Removes a thin layer of plaster each time

•Can only be done a limited number of times

•Won't fix structural damage, cracks, or rough texture

•Not effective on deeply embedded stains

Pool Resurfacing: The Complete Renewal

Resurfacing involves applying a completely new finish over your existing pool shell. Options include standard white plaster, colored plaster, pebble finishes, and quartz aggregate.

When Resurfacing Is Necessary

•Rough, sandpaper-like texture that irritates skin

•Visible cracks or delamination (plaster separating from shell)

•Plaster too thin for another acid wash

•Persistent leaks through the surface

•Desire to change the pool's appearance or finish type

•Pool is 10-15+ years old with original plaster

Resurfacing Pros

•Brand new surface with full lifespan ahead

•Opportunity to upgrade finish material

•Fixes structural surface issues

•Can change pool color and aesthetic

•Lasts 10-15+ years depending on material

Resurfacing Cons

•Significantly higher cost ($5,000-$15,000+)

•Takes 1-2 weeks to complete

•Pool out of service for 2-4 weeks including cure time

•More disruptive to your yard and schedule
