I used this stuff on my driveway and around my pool, best stuff on the market. Key is making sure the prep work is perfect. I live in Michigan I've had my driveway plowed many times didn't even scratch the stuff. I think it literally would take Dynamite to get this stuff out. Applied it in 2015
Proper way to do around a pool is clean up your crack put silica sand about a quarter-inch to the to half-inch of the silica sand in the crack then filled with deck-o-seal then wait a few seconds then throw silica sand on top of the deck-o-seal to give a concrete texturing look
I always use sand to fill in the large gaps or voids. A 50lbs bag goes a long way. Sanding while tacky is a nice finishing touch. Your finished work looks good!
Nice job. I have a gap as wide as 2 inches between where the pavers end and where the pool edge starts (ie..curved white edge.) Could I do this process with backer rods and the sealant? Will it hold up to kids jumping in pool ahd overslash for a good amount of time? Right now I'm using gator dust. Thanks
I used three large tubes. This is similar to the blade I used on my oscillating saw: www.homedepot.com/p/DEWALT-Oscillating-Multi-Material-Blade-DWA4214/204793130
Good question. I had my pool copings reset and deck seal replaced and I don’t like the job they did with the seal. For one there was a lot of wavy spots where there was run off I guess they over filled some areas. I too wondered if I could go around cutting a straight edge to it. Next time it needs replacing I’m doing it on my own.
The blade I used on this project has been in service for several years and multiple projects. Fresh blades are always great, but I find these oscillating blades to be very durable when used on wood.
Hi, I'm a new DIYer and have the same problem. I have an Old inground pool and there was no mastic backer etc. seems like it moved a bit. I'll need to use that tool to remove some concrete that appears to have shifted into that space in some areas. what is the name of that tool you used to clean the area up before placing backer rod? Also do you know how deep the backer rod should go down?? Thank You Elaine
The tool is called an oscillating saw. Most of these tools come with a small assortment of bits, but you may want to consider buying a knife-edge tool for this job, it goes through the old mastic like butter. The backer rod should sit 3/4”-1” below the deck. If your gap is deeper than this, use some all-purpose sand to fill in the gap before the backer rod.
It’s been three years since I conducted this repair and I got at least two flawless years out of the new mastic seal. This past winter, the mastic started separating from the coping again and I had a little more settling in the pool deck. I think another repair may buy me enough time to plan my pool deck replacement.
Monica. Buy polymeric sand from HD. It's found in the garden section. Add a little water, once you filled gaps with a broom. The water helps solidify the sand.
Due to the size of my gap, I used three large tubes to get down one side of my pool. With a regular gap, you could probably do the entire pool with 3 large tubes.
Sean & Jacqueline Kerrigan I wouldn’t expect the new mastic to bond well with the old mastic. It’s quite easy to remove the mastic once you get a loose end, so I would advise removing and replacing all old mastic.
What type of stones are those for your coping? I have the same ones and looking to replace a couple that have disintgrated. Not sure where I can find replacements.
In my case, the pool deck is settling due to water running under the deck and down the hill behind the fence. The ultimate solution will be installing a footing under the deck during a remodel.
@@EkalbGnilrad sand as a base is better. mastic will crack in middle and sink again sooner than if used sand backer its a much better grip and would only have required 1/8th inch groove at top leading to little sika needed. we charge 7.00 a linear foot for this and good reasoning. lasts for many many years if installed correctly
Thanks for following up! The mastic held up great until this summer. The new mastic is just starting to separate from the coping, but it’s been great up until this month.
@@EkalbGnilrad- thats a bummer. I had a pool service that did mastic install last time. It has lasted 7 years. I just installed this product on my driveway. Not looking forward to redoing that job in three years. I thought this was permanent? Haha. At least longer than three years.
@@jbright97 on closer examination, the mastic is in great shape in many areas. The sections that need repair have more to do with the deck continuing to shift rather than the mastic deteriorating.
Folks let a professional certified pool and spa operator do this work. The reason this "man" didn't notice the pitfalls until after the work was done, was because he didn't put sand in before laying the mastic down. By putting sand down you will see the pitfalls and seal them appropriately prior to applying the mastic.
Well, I haven't come across many professionals with craftsmanship and pride in their work. There are too many grifters and I have learned that if I am willing to put in the sweat and due diligence I do a very good job.
Replace you're hydrostats.. I'm guessing they are sticking a bit and allowing ground water to flex you're pool.. ... Pop the main drain covers off and grab that octagonal thing and lift up and release a few times to clear the debris.. your can replace each one for about 20bucks.. if you have the basic understanding of plumbing..
Good eye there! Two unfortunate realities exist here: 1) the pool isn't lifting, it's actually settling on the shallow end and the deck is drifting down the slope behind the pool and 2) when I drained the pool last summer, I couldn't find any hydrostatic valves anywhere in the shell. Not in the main drain compartment and not in the floor of the pool...they may have been surfaced over when the plaster was replaced years ago. At any rate, I'm pretty far up on a hill, so I suspect the water table is 80-100 feet below my pool.

Thank you for sharing I also have seen for bigger gaps to use a pool noodle and cut it to the size needed.
Been looking at my cracking mastic for a few years. Glad I watched; be completing this summer. Good ol Calif sun blasts everything! Good video!
Me too it's time to do mine again. I also live in So California I get in the pool while I run the bead, so I can stay cool.
I do this in Cali! Just saying lol.
@@HRTsAFyreI always want to just into customer pools when I go do their mastic. Lucky you get to jump in 🤣🤣
Thank you this was very useful

K B Great idea - sand!
can i use sand PLUS the backer rod foam if the gap is quite big? or only sand needed?
Great Video!
Thanks for the video! About to do this myself. This was helpful.
Neptunus Rex no don’t use that crap use deck o seal
nice informative video. thx.
Add foam or silica sand to fill in any holes and you won’t have a problem with mastic sinking, prep it’s very important. Good job tho 👌

I’m sure you did it already, but backer rod is perfect!
Where can you find the Sika Self Pro Select Self-Sealing Sealant? Where can you find the closed celled backer rod?
How many tubes did you use to do your pool and how many feet does that consist of?
Nice video, short and sweet. What dremel bit did you use?
Thanks! I used a simple flat blade attachment. Old mastic cuts really easily.
Is it hard to remove the old mastic ?
Thank you
How many tubes did this project take?? Can you link the tool and blade you used? Looks great, thanks!
I used three large tubes. This is similar to the blade I used on my oscillating saw:
www.homedepot.com/p/DEWALT-Oscillating-Multi-Material-Blade-DWA4214/204793130
3 large tubes for the whole pool?
How many did you use?
Do you know if you can trim off dried mastic overflow? Thanks!
Mike Belie I think you can prep the work with scotch tape

How many uses do you get from each blade using using the oscillating tool?

curious what did you end up doing after winter? I have this issue right now but not to the same degree as your gap.

what power tool did you use to remove the old mastic?
yetijoeyetijoe I used an oscillating tool with a scraper blade.
Blake Darling thanks. I just got back from Northern Tools. Bought one plus a couple of extra scraper blades.
Need to caulk inside my fiberglass and concert pool..don't know what sealant to use..no help at store
If I were to add sand, what kind would I use? Thanks!
Monica. Buy polymeric sand from HD. It's found in the garden section. Add a little water, once you filled gaps with a broom. The water helps solidify the sand.

Due to the size of my gap, I used three large tubes to get down one side of my pool. With a regular gap, you could probably do the entire pool with 3 large tubes.
can you repair if its not so damaged ?
Sean & Jacqueline Kerrigan I wouldn’t expect the new mastic to bond well with the old mastic. It’s quite easy to remove the mastic once you get a loose end, so I would advise removing and replacing all old mastic.
What type of stones are those for your coping? I have the same ones and looking to replace a couple that have disintgrated. Not sure where I can find replacements.
Did you find out about the stones? I have the same ones and the same problem
What causes this separation? Our pool is developing this a little
In my case, the pool deck is settling due to water running under the deck and down the hill behind the fence. The ultimate solution will be installing a footing under the deck during a remodel.
What you call the tube and where to buy it
Sika Self Pro Select Self-Sealing Sealant can be found at Home Depot or Ace Hardware.
Sika or Deck O Seal, which one is best, or are they both comparable? Thx
Did you use sand?
I opted out of sand, I think it looks fine with a bit of a sheen to it.

The guestion I asked was for in the pool expansion joints.This has nothing to do with inside the pool expansion joint.
I’m sorry Mr. Wells. I will inform the algorithm monkey and make sure he never makes that mistake again. 😂. Have a nice day!
