    expansion joints

    Hello all,
    I am just finishing having our gunite pool completed. The concrete deck was recently poured and the concrete guys says I need to caulk the expansion joints sometime in the fall. He said when I am closing for the season to do it. So I am wondering if anybody has any advice for this. I plan to do it myself (I consider myself pretty handy around the house). What is a good caulk for this? Do I need to cut out some of the foam backer that they put in between the coping and concrete? And do I need to do anything for the white plastic things that they put in between the concrete sections? Thanks for the help.

    Welcome to TFP!

    A caulk like Vulkem 45 is what you're looking for. You will need some backer rod most likely.
