I have designed a walkway on a 4X8 that leads from the deck into our Turtle Garden.
What I am looking for is a material that will withstand the freeze/thaw cycles of the north, as well as being poured and tinted, to fill in the gaps of the material on this walkway as well as protect some from UV.
The pictures don't show it, but I am bringing PT 1" pine to within Â¾" or an inch of the borders and there will be a lot of space inbetween to fill in.
I have thought about sand based grout, silicone, resin, poly-urethane and some other materials, but need to be able to pour it into the cracks and let it flow. I do NOT want it to go above the level of the letters or the turtle pieces which are made from 1" PT decking boards.
Not to repeat, but this will be part of a walkway and therefor will be walked on.
Anyone have any ideas?
