They applied mastic around 2-3 weeks ago. I was told it is named “deckoseal.” After wiping out the sand last week … this is the end result. Stains all over the decking and coping. I’m pretty devastated to say the least. I brought it up to my pb and he has no idea what happened and hasn’t provided a solution. Honestly, I can’t think of a solution to this. I don’t even know how this happened. Did they spill ? Is it absorption ?Any advice?

Anthony,
What do you mean "Wiping out the sand?" Did you do that or the pool builder?
Thanks,
Jim R.

So the guys threw globs of sand after applying the seal…. Then they left. Never came back to sweep it up. So I just took it upon myself to clean up the sand after it had just been sitting there for more than a week.
That’s what I thought as well… but I swept the sand off around a week ago and it hasn’t improved.
Is it pour concrete or individual blocks? Ask the PB if he would be happy if that was at his house and how he thinks it can be fixed. Let us know what he says.
My gut says remove and redo!

Truthfully, that DeckoSeal looks among the better applied I've seen. It's nice and smooth and even width. We've seen so many that look like a child's first time with Elmer's glue.
That darkening is something we've also seen as moisture trapped in the joint. The sealant alters the rate of evaporation of moisture the control joints because it is wateroof. There is no "product" for them to have gotten anywhere that would appear that way in the kit.
The sand is optional and is applied for texture and aesthetic so it appears more like concrete while being able to handle the shift of the monolithic pool shell. Regular grout would shatter.
I'd give it time; being mindful that high humidity or periodic rain will prolong the moisture but eventually it should fade.

Thanks for your response. You seem very knowledgeable regarding pools. I would also like to add that the day after they applied the deckoseal, it rained a whole lot for several days. So maybe the rain has a lot to do with it. I’m hoping it’s only moisture and not oils that are trapped. Thanks again.
When backer rod is not used then sand will be used in its place to level the gap and fill any voids, water is typically added to help compact the sand once in place before the mastic is applied.
