Thanks Lee ! To keep it wet, can you put plastic over it, or pour it on a day when you know it's gonna rain? Or is that bad?

You know, dig out the area maybe 6", put down wet sand and level, then set the frame and pour the concrete. Then, when it's still wet but firm enough things ownt sink down into it, use small decorative rocks to press into the surface of the marker spelling out the name and years.

Kathleen, It is best not to let it rain on the fresh concrete. Plastic tends to discolor the concrete because of what is called the "greenhouse effect". Wet burlap or similar wet cloths are best and most practical, although there are other ways to cure it. Lee L.

KATHLEEN: Here in Portland, OR. where it rains a lot and if it is not raining it is going to soon, they build a tent over the fresh concrete with clear plastic.
