Formed a crack in my steps last year, other than acid, anyway of determining which material they are? I heard if the're fiberglass they can be repaired. A local company quoted me $5000 to replace, seems high to me.
Thanks for all the tips, just i to give an update.
Today I was having a pool company in area fix my steps ($2300). A "painter" showed up and commented that he had never done pool steps before and was very confused. I asked him what he was going to be using to fix the crack and he showed me a fiberglass repair kit he got at walmart and two-part epoxy paint. I was shocked that I was about to pay 2 grand for something I could do on my own. I was under impression that it was a "special paint" and a "special process". He even told me that it would be impossible for him to match up the diamond tread. A few phone calls later and a trip to the hardware store and I'm officially going to fix it myself.
My question and slight problem. The steps where the crack formed are moving a lot when weight is placed on them. I drilled a 1/2'' hole at current crack and one at other end to see if there were any supports. From what I could see was a space from crack to more plastic/fiberglass. When i stuck a screwdriver in the hole the plastic angles down toward bottom of current cracked step. (I'll try to diagram). I'm going to attempt to fill in the steps with sand and expansion foam but I'm wondering if the sides are open or if there is any space in the steps void. My pool was definitely leaking from the steps so water had to of gone somewhere. Do you think the sand and expansion foam will help with the movement?
