| Not sure if this is an ok question here but I just bought 2 expensive concrete urns and a huge concrete bowl. I'm planning on planting semps and sedums next spring. They are in the garden now and too heavy to move in every winter. Do they need sealed before planting? What would I seal it with if they do? Thanks. I live in CT with some cold snowy winters. |

| I guess the first question since, this is a forum full of tufa nuts - Why would you buy concrete? Rather make it out of something that will not be so likely to crack. Sorry had to ask, they probably look cool. I think that what ever you use to seal them , you will have to do it every year. Esp in CT. They shape of the container is important. If it is open, like a bowl it will be less likely to crack due to frost heave. I would look on line for a high quality concrete sealer. Products like Thompson s water seal are ok, but maybe not as long lasting as high quality sealer. Wait till next year, most sealers need warm temps .. Good luck |

| They do not need to be sealed. They will need to have excellent drainage tho. They should weather for a few years before painting. If you wanted to paint it now I would wash them in a mild acid. You can just paint it with an acrylic paint. I painted a concrete bird bath with a high gloss acrylic 15 years ago. It needs repainting but the paint job did very well. I painted the entire piece. Its may be best to use an interior/exterior high gloss acrylic paint, because it have enough vehicle to penetrate and seal it. I would not use silicone products because they evaporates in a month or two. You could paint it to look like aged copper. That would be the best idea if you like that look. I have been a commercial painting contractor and have painted lots of concrete. When you paint it it must be painted on the inside as well as out to have a consistent perm rate. Acid does not mean vinegar, don't worry about it, just don't drop it. |

| I would strongly consider staining vs painting but thats just me, just look up stained concrete, they come in almost any color. |
