Sealant vs. mortar for stone-to-concrete
Jeff_Clarke
| Posted in Construction Techniques on
I have a number of conditions where bluestone will abut concrete with a 3/8″ – 1/2″ wide joint. These are under cover, but can get wet from wind-driven rain and snow.
I know that mortaring the joints is asking for trouble – what I think might be best is to use a single-component self-leveling urethane (Sika) and add sand to the top before it cures.
Any other ideas? The tile folks have sanded sealants for control joints but they don’t seem to be rated for traffic/outdoor use.
Looking for the appearance of a mortar joint without the cracks.
Thanks!
Jeff

check out quikrete grey concrete crack filler.
Is this what you mean - http://www.quikrete.com/ProductLines/ConcreteCrackSeal.asp?I'd be concerned about a latex product holding up in a long 3/8" joint.
I think this would be the product from Quikrete - http://www.quikrete.com/ProductLines/PolySelfLevelingSealant.asp but I don't know if you can sprinkle sand on it.

Vulcum sealent...

WOW!!! What a Ride!

Sika has a textured product - http://www.sikaconstruction.com/tds-cpd-SikaflexTexturedSealant-us.pdf but it says it can yellow.
Anyone try this?

Do not use the SIKA. I've used it for nearly the same application from brick to concrete. I'm not sure how the tube gets away with saying it's approved for highways and tarmacks cause it' didn't last a full winter for me. That was the only reason I bought it too, cause I figured if it works for tarmacks with 100 ton jumbo jets slamming into it all day than it would be more than enough for my sidewalk.
Use a Vulcanized caulk in gray(and sprinkle sand on it if you'd still like) used to seal commercial aluminum store window frames to brick. Just today I was demoing such a frame with a 16lbs. sledge and 4' Johnson bar trying to pry it free. As one of the glazers came by I told him, man this thing is pissing me off. He said I'll bet, you've got it totally broke free and it's just the caulk still holding it. Slip a sawzall in the caulk joint and cut it (a knife wouldn't be enough to cut it.). He said further, you could set one of those frames, caulk it and once set pull all the screws back out and it would never go anywhere.
that sounds like Vulcum....Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming<!----><!----><!---->

Ya, that's exactly right. I can't ever remember the name and the closest I come to in sounding like it is vulcanized like the rubber, And that's exactly what the stuff acts like. More like a rubber melted to what ever it's on than like a caulk.
