How to Repair Pool Deck Coating Safely and Effectively
Repair pool deck coating by identifying the damage, removing loose coating, fixing the substrate first, and using a compatible patch or resurface method.

To properly repair a pool deck coating, one must first clean the area of damage and remove any loose material. It is also important to get to the root of the problem before attempting to resurface or put in a patch; an unstable substrate will see any surface patch fail in short order. While minor chips and wear can be mended in place, issues like peeling, movement or cracks that are widening call for a professional’s eye.
What is the extent of the damage?
A close inspection of the pool deck will tell you what you are dealing with:
- Small chips, scuffs or worn texture: These are generally amenable to a localised repair.
- Peeling or flaking: The loose material has to be taken off prior to reapplying any coating.
- Hairline cracks: Could be merely cosmetic, or they may be evidence of stress in the concrete.
- Hollow spots or soft areas: A sign that the substrate itself requires attention.
- *Stains*: In some cases, no structural work is called for.
Should you find that the deck is settling or that cracks have a habit of coming back, it is best to stop and seek out qualified assistance. The failure of the coating is often a symptom rather than the underlying issue.
Preparing the deck for work
There is a world of difference between a hasty job and one that holds up over time, and good preparation is key. Adhere to the manufacturer’s instructions for your particular system, be it an acrylic or cool deck finish.
1. Shut down the pump if you need to get at the skimmer basket or other equipment. 2. Clear the deck of dust, grit and leaves by sweeping. 3. Give it a wash to take care of algae, sunscreen film and chalky residue. 4. Get rid of any unsound concrete or coating that is not holding on. 5. Allow the surface to dry out. 6. Put masking tape on the edges and poolside fixtures as necessary.
Make sure there is no damp cement, dust or loose coating left to be patched over. And if conditions are slippery, be mindful of your PPE and footwear.
Choosing a repair method
The approach should be dictated by the depth of the damage. For something on the surface, a patch from a kit compatible with your current system will do. Where the concrete is broken or exposed, that has to be put right before the top layer is resurfaced. With widespread wear, spot repairs are less effective than a more extensive project. Textured or stamped finishes can be hard to match, so blending in the repair is something a pro might be better suited for. Stick to products the label approves for your pool deck and do not mix materials unless explicitly permitted.
Is it time to bring in a professional?
Not every problem is a DIY fix. A coatings contractor or pool specialist should be contacted for:
- Cracks that return or open up
- Any settling, drainage or movement of the deck
- Water getting under the coating
- Multiple areas of peeling
- Damage to the pool shell edge or expansion joints
- A need to put slip resistance back into the finish
In these instances, a simple patch will not suffice; concrete resurfacing may be in order.
Pitfalls to avoid
Most repair failures are the result of a rushed job or poor diagnosis. Pool owners would be well advised to avoid:
- Putting a patch on top of loose coating
- Working on a damp deck
- Overlooking movement cracks
- Using an unapproved product
- Walking on the repair too soon
Respect the curing times and safe handling guidelines on the label. Never try to make a repair on live suction equipment or enter the suction outlets.
Making the repair stand the test of time
Once the new coating has cured, the aim is to keep the deck as dry and clean as can be. Promptly tending to stains and ensuring proper drainage will go a long way in minimising abrasion. If the surface gives way in the same spot once more, there is likely something wrong below the coating. When in doubt, particularly with anything that could affect the structure or bond of the deck, have a professional come and look at it.
