Pool Deck Mastic / Coping Seal

[reinnov8r]

Hi everyone. It's time to replace the mastic / grout between my coping and exposed aggregate pool deck. Is Sika a good option from Home Depot or Lowes? Is there something else I should be looking at? Any other tips or advice would be appreciated.

Thanks!

I did some searching and landed on Sika polyurethane. I don’t have coping separate from deck, have a concrete cantilever and expansion seam at the pool tile where I used this. I used silicone for the pool, and it’s not holding up well, so I did the spa this summer with this Sika polyurethane and it turned out great. Much more messy than silicone, but I used outdoor masking tape, smoothed out with thumb, and it left a fantastic border.
