Can I use pool epoxy to fill gaps between coping and tiles? Attached pic

[rozus]

Not sure what I can use to fill in these gaps. I have pool epoxy at homes, but I wasn’t sure if that is the right thing to use. Thanks in advance.

Better to use grout…

Thanks @ajw22 . Please excuse my ignorance, is this material can be used around tiles, as well as between coping/travertine and tiles?

Mark on your pics the gaps you are trying to fill.

Epoxy isn't good as it'll bond to the coping and tile and should the coping move it'll take the tile with it.

I was planning to use ezpatch as ajw22 recommended. Would you recommend the same thing? Is there a reason pb left it empty like that?

 

[rozus]

Other corners, and the rest of the line between coping and tile, seems like grout was used. Nothing flexible in those areas. I am just not able to understand how epoxy can bond and take the tile away while grout can’t if coping moves? What am I missing?

Why do you think that gap should be sealed?

What type of deck do you have? Where is your expansion joint?

@ajw22 Sorry for the delay. I was trying to find some paperwork from previous owners. Here is what I found, but it doesn’t show the corner with the gazibo column. Please see the pics. Also, I thought it shouldn’t be sealed because everywhere else between coping and tiles are sealed with grout. I thought it should be sealed because water might go in and create problems in the future?? Please see the attached. Appreciate the help

I called a pool builder company and show them the images. They said to use a product called Vulkem 116 polyurethane to fill the gaps, and said do not use grout of any sort. They said grout shouldn’t have been used in remaning gaps between coping and tile line. I’m so confused.

 

[ajw22]

You are confused because you are showing many different surfaces and it is not clear which one we are discussing. Let’s stick to one at a time.

Vulkem 116 is the right product for joints that may have movement.

Grout needs to be used in joints that are stable and have no movement.

Pool epoxy is never the right product to use around tile and coping unless you are looking to patch a leak or crack.

sorry I was just trying to show surroundings. For this one below specific. Do I use grout in highlighted then?
They are the same sections

Use polyurethane caulk. There will be tiny movement there and the poly is a bit flexible to allow for that.

I think it's debatable that that gap even needs to be sealed but that's your call.

Thank you so much, @duraleigh . This is super helpful.

I would leave that gap as is.

Water from your pool should never get up to it.

Trying to stuff polyurethane caulk into that small slit will likely make a mess of the tile below.

How about if the pool overflows during closed season winter time? And splashes? So many kids use this pool and splashed in every corner. Would that be enough problem to cause headaches in the future? Like freezing water in winter got in during summer and damage structure?

First of all, don't let your pool overflow.

You will never be able to seal all the gaps. And if you think you do new ones will open up.

And splashes? So many kids use this pool and splashed in every corner.

I doubt much, if any, splashed water finds its way into the crack.

Water that got in there during the summer will not be lying in wait to freeze in the winter to cause damage.

Water evaporates pretty quickly.
