How do i fix coping?

[Dwiessner]

Hi all. We have a Fiberglass pool with concrete coping. Structurally, the coping looks great. On the surface though, it's falling apart where it's most exposed to the salt water. Slowly crumbling and leaving a sharp surface. What can I use to seal the coping to prevent further deterioration? Looking for something non- slip, easy to put on, that I can get at least a few years out of before having to reapply.

Ive seen some products at home depot that look promising, but would love to hear from someone who's actually tried it.

I doubt the concrete failure is due to saltwater. Typically surface failure of concrete is from poor mix (alkali aggregate) or too rapid of curing of the surface after the pour.

Other members may have more detail. I do suggest using Google and search for 'concrete surface deterioration'.

First a few questions:

Did you have the concrete poured or inherit it? If former, have your asked the contractor what they believe is the issue?

Do you know the age of the coping? If yes, how long did it take until the coping started to deteriorate?

Next, can you post a few pictures?

We inherited. Not sure of the age, but probably 10 to 15 years old. I'll try to post a picture soon.

This is the worst piece. The rest are less worn, but similar

If you take a metal object and try scraping the lighter part of coping, what happens?

Is the lighter part the original concrete and what's left the eroded parts?

Trying to diagnose this over the net w out being there is kind of tough, but I would consult w a masonry expert that has a fair amt of experience working around pools. My initial thoughts are this was poured during the very hot time of the year or not enough adequate moisture and it dried too quickly, or some combination. Again, really hard w out being there but someone w a lot of concrete experience should be able to diagnose this for you
