concrete question

kraftkrazyOctober 13, 2009

i have a friend that has a big concrete fountain that she wants to mosaic. but, she recently discovered a leak in the basin and she asked me how to repair it. i havent worked with concrete but told her i knew where to go to get answers, so i am asking you guys. her brother in law told her to coat the inside with mastic but i didnt think that was right, so i told her to use either quickcrete or thinset, but i am not so sure i am right either. does anyone here have a fix thats not too complicated.

Depending on how big the leak is. I use the spray on undercoating for cars and spray the inside of mine and that stops most leaks. There is also a repair product at Lowes that is like an expoxy and it seals, even underwater. She can also pur a good coat of thinset all over the inside and then seal with the spray on undercoating. I use this stuff a lot for birdbaths and inside pots to waterproof. It can definitely be fixed. I can get the name of the product at Lowes but it will be in the morning as it is in my studio and it is dark and rainy here. Hope this helps. As everyone has told you, adhere the tess with thinset.
