Hopefully you don't start charging me for questions. I am selling a house and the inspector for the seller wants me to fill a floor crack in the basement with a flexible filler. Can someone give me a name for something g like this?
Don't no the name off hand but you will find with other caulks, it comes in a tube.
Your best bet is a waterproof filler from DAP:http://www.dap.com/product_details.aspx?product_id=18
Good luck with the sale!
