I had two cement bathroom sinks repaired and resurfaced. One sink turned out fine, the other has squishy bubbled up places in the finish. They have tried to fix it twice, but it's still there. I was told the cement must have a contamination in it that's causing the problem. They had never seen this before. My house was on the market and has sold, so I'm out of time to keep trying. I contacted them weeks ago and said the bubbles were still there and left another message after that. It appears they are not going to set up a time to come try again. Nor have I been offered a refund of any kind, since I did not get what I paid for. This has been going on for months and never resolved. Because of the shiny surface, the bubbled up places are hard to see, so I'm sure our buyer did not notice them. I'm afraid when something is dropped in the sink, the bubbles will tear open on them. Additionally, if I had been shown the paperwork they left me with beforehand, I would not have done this to begin with. I told Mr. Hickman I was having trouble with the original finish, and that everything dropped into the sink would nick it, and it would begin to peel and that I wanted something tough and chemical resistant. He said he could do that. The paperwork says don't drop things in the sink and if you are using bleach mix with water to 10% only and never get nail polish remover on it (no one has that in their bathroom, right?). How is that tough and chemical resistant? A guy can't drop his razor, and find somewhere else to do your nails. Same problems I had to begin with. Also, I asked Mr. Hickman if they could handle the plumbing. He just said yes, with no qualifications. Turns out, that's only if there are no problems. So, be aware you may end up paying a plumber anyway or doing it yourself, if something goes awry, like a part breaks. Update: Mr. Hickman has since told me the paperwork that I was left with does not apply to the finish we got (except for the nail polish remover part) ... but that's what the the tech gave me, and that's still a problem. My husband did drop his razor and it nicked the finish. Given the bubbles, it appears it hasn't adhered properly to the surface. read more
