Sorry there has been no answers yet. To me it does look like concrete with an overlay on it. The texture is what makes me think there is something like Kool deck on it. As far as what it is exactly I really don't know. I don't have any idea what to tell you to use for fill in the cracks. My thoughts are "fixing" the cracks will make them stand out more. They seem to be smallish and not really causing any problems.

When was the last time you did a good, deep clean of the deck? Me? I would move everything then get some bleach and a good scrub brush on a pole and have a go at it to see if that will get you some visual satisfaction.

Have you ever power washed the deck? If so did the surface stay intact or flake away?
 
About to fix some small cracks and fix some missing knock down areas from erosion and chipping. What material should I use to repair?
Is this cool deck as opposed to Kool Deck? What is the material , it looks like concrete to me.

I was looking at this: https://www.amazon.com/gp/product/B002WKM798/ref=ox_sc_act_title_1?smid=A3VDBPE82S43CG&psc=1
The ezpatch stuff is much more expensive than the stuff Home Depot carries that does the same thing. Don’t know if it’s appropriate to repair kool deck though.

Thank you for the reply. I just bought the house, this is the original deck from '98. I have pressure washed it and tried bleach as well. This weekend I'll try scrubbing with some TSP. I am beginning to believe that a lot of that dirty color is actually the concrete surface under the overlay. I can't remove any of the overlay with pressure or scrubbing. I am trying to determine the overlay material so I can find a the best repair product.
 
Not always, Dirk. Hard to tell from pics. So let’s do a test. Take an acid, say white vinegar, and apply it with a q-tip in an out-of-the-way place, preferably a soiled area. Agitate the vinegar with the q-tip or a toothbrush, blot w paper towel. You can repeat if you notice an improvement.

If no discernible result, we can try a stronger acid but let’s wait and see the results of first test. Take before & after pics

Here is the test area, control on the left, vinegar on the right. I have some muriatic acid in the garage.
I have also noticed on the areas where I am able to pull the texture off, there is a green mold (second photo), doesn't this rule out stucco?

There is a product called Concrobium, a non toxic anti-microbial that is both a cleaner and a mitgator of mold, etc. There is a general public brand in Home Depot and Lowes-Concrobium Mold Control. Follow the directions. Take pics. The important point is that chemicals need dwell time with the surface to be effective along with agitation, and rewetting as needed. A more professional strength could be obtained at contractor supply sites. The one I use is Home in CA. Knowledgeable.

Looks like an acrylic surface coating.

I would strip off all of the existing coating and get it resurfaced.

This is an acrylic coating sprayed onto the slab and then troweled by hand. The result is a stucco-like finish that is safe against slips and falls. One notable feature of spray texture is that the cool decking stays 30% cooler underfoot than other materials. A great option for covering stubborn stains.


What types of pool deck surfaces, finishes, and flooring options do you offer?

Natural, stamped, stenciled, and colored concrete from our decorative concrete experts, broom and rock salt finish, exposed aggregate, brick and tile, acrylic lace coating, acrylic stamp patterns, kool and cool deck, slate, cantera stone, flagstone, granite, limestone, bluestone, travertine, sand stone, coral stone, and duracrete.

 

Note: Companies are just examples, not recommendations.

I don't know if the companies are good or not.

Do your due diligence when choosing a contractor.

Maybe at least get an estimate from a company to get their opinion about what surface you have as well as the options and costs.

You might be able to just remove the loose parts and then recoat after cleaning.
