Repairing cracks

[LegacyIndustrial]

Gargage Journal fans:

We posted some nice photos of a concrete crack repair procedure. It can be used for small holes, joints and imperfections too.
The product shown will fill and seal the crack, plus it will bond the slabs.

Check out the link attached.

Thanks,

Thanks for showing the process. I'm still waiting to see how bad my slab gets. Its 50 days and has developed a few more of those hairline surface cracks. I'm still not sure if the finish will pop up yet.

 

[LegacyIndustrial]

No problem.
The crack shown is part of a floor that is being coated over and therefore will be hidden. We didn't tape it off or scrape it. Some pictures will be added once the floor has been coated with our industrial tri-coat system.

You can tape off the sides of a joint/crack or razor scrape it once it has tacked off to make it look nice and neat.

I have an older floor that I've already epoxied using the U-Coat it product. I was in too much of a hurry and didn't patch the cracks before I applied the coating. Will your product still work for me, and if so, how would I clean up any excess that would likely end being along the edges of the crack? PM me if you'd prefer.
Thanks, Mike

Howdy Mike:
Yes, you can use this product. Three ways to keep it clean. You can tape off the side of the crack or joint with duct tape, pull the tape once it gets tacky.
or... you can use a small spackle knife and be very careful, or... you can put it down willy-nilly and once it starts to to tack-off you can scrape off the excess with a razor scraper, cut it level with the floor.

Repairing cracks??
Your product is called: Legacy Industrial's HD-821 Gel Crack Filler
I think filler is the key word here.
I'm really not trying to be difficult here - I actually understand in a way. You just hit my 'word used in the wrong context' button here.
Now that I have that out of my system -carry on

 

[LegacyIndustrial]

Oh no, PassnThru, not off the hook that easy.
It is a filler. It fills the crack and bonds the slab. It is not caulk, it will support the weight of a fork-truck and yet still flex enough to resist failure. I dare you to get it out of the crack once it cures without a blow-torch or a .30-.30 .

Please explain how this is out of context.

I'm sure it's very tough. I guess my question would be once you put it in there can the crack get any bigger or is it actually capable of holding the two sides together now?

It has very good elongation. We bill it as a slab bonder. Everything is relative to the application, slab thickness, amount of movement, etc...

Will your product also work on outdoor slabs (patio/pool) in climate that ranges from very warn to extremly cold (upstate NY)?

I hear ya. Bonding to each slab is great along with some good old elongation - elongation is good - very good elongation is even better

I mean, if you're gonna fill'er.....

Yes, it can be used outside. It can be used into the thirties, take a little longer to cure than normal.

Can you post a direct link to your HD-821 product. I cannot find it on your website.

Doh, found it. Price jump from 1/2 gallon to 2 gallon is $6. Odd.

The 75.00 gets added to the base price of 69.00 giving you $144.00. for the larger quantity.
It's a bit odd but it works, most folks want the smaller quantities, especially garage forum people.

 

[letterman52]

I sent you a PM on this stuff and another product just like it you offer. Let me know if a quart would be enough.

 

[LegacyIndustrial]

Letterman:

Just replied. Our vertical formula is for walls, extra sticky and viscous, use the HD-821 Gel crack filler for joints and cracks on floors. It's easy to use and is a 1:1 mix. Eye-ball it and only use what you need.

Reviving old thread.

Can you use this product when overlaying with an acid etch stain? I'm guessing no, as acid etch needs concrete to react, if not...then what product would you recommend. I have shrinkage cracks all over (less than 1/8").

I've also looked into the following product (not an acid etch)...was wondering if it would bond to your crack repair product:

You and I spoke today.
Stain first, repair crack, seal with HD015 Clear Sealer, (2) thin coats and you will have an awesome system. This can be top-coated with urethane if desired for even more durability.
