  4. Dunno, seems to me like the hand rubbing and float wiping is doing two things I wouldn't want:

    a. it is spreading caulk out into the surrounding texture which serves to FLATTEN the texture somewhat in those areas (hey, think about it, it gets wiped into the valleys, not onto the peaks…) (this I learned from patching nail holes in drywall that's textured, like orange peel. — After you spackle the hole, take a second to run a well-pressed thumb AROUND the hole and REMOVE any spackle that got spread out into the surrounding texture so that there's ONLY spackle precisely where the hole was, not a drop of it anywhere else on the wall to flatten that texture! p.s. if the hole was dime-sized or larger, you'll want a can of spray texture to make that dime disappear so that the whole thing is invisible after painting…)

    b. it is making the actual groove being caulked in very flat surfaced (clearly visible in the video, look at that upside-down smile of a crack at 2:41 in the video, smooth as a baby's butt! yikes!) despite the "sandi-ness" of the caulk, it's still overly smooth compared to the stucco. I'm guessing that's why we weren't treated to an "after-painting" view of this area…

    Both of these are bad when you get to painting as they're going to make this repair visible by letting it show a flat area in the stucco that follows the original cracks path.

    Me, I don't think I'd dress it out AT ALL with a gloved hand or a float. Seriously. Leave the build up there so that it CAN'T become a flat line that outlines the way the crack went. I WANT some of that caulk sticking UP PROUD OF THE SURFACE along the crack randomly so that the "run" of the crack is broken up as much as possible along its length. Instead, I'm just taking a stippling brush (or any stiff long bristled brush), and I'm gonna pat those bristles into that fresh juicy caulk. Very minimally. Gently. Maybe just once or twice in any one spot. I'd probably try that with wetting the brush first, and not wetting it to see how that makes the caulk shape up. I'd even try waiting a few different timeframes to let the caulk start to set up a tiny bit before patting. I'm betting there's a nearly perfect amount of time to wait that patted once or twice you'd almost need a magnifying glass to spot the crack! 😉

    Goal for me is to get that caulk to stand up proud, and take on the rough, non-uniform shape of the original stucco so that we CAN'T SEE ANY HINT OF A CRACK.

    But that's just me. I'll try and let you know how it goes as I just ordered the MorFlexx from the rain forest store online, 'cause that looks like exactly the right stuff to use… now where's that brush??? 😉

    • Howdy B Miller, good eye, and lots of good advice there, brother, thank you,
      Sometimes I do end a video if the point is made so that these video's aren't too long, but before leaving a repair and while Jason Is putting the camera away, I do go back over any imperfections to feather in to the best of my abilities.
      Cheers,

    • Howdy Kraig Stanforth, the only time you don't want to seal the stucco is if you have a maintenance free color finish on a stucco home, as this is like a brick, the color last forever or never peels off like paint does, but once you do paint your stuck painting every 10 to 12 years.
      Otherwise I have never understood what folks mean when they say don't seal stucco, all paint if it's of quality seals the walls a bit.
      I usually recommend the Kelly Moore elastomeric system myself or something comparable.
      Cheers,

  6. quick question how can a stucco trimming around the has be fixed, it's like a design, similar to what's around around the window frame. at this point it's starting to chip. thank you ahead a time hope I didn't confuse you…

  7. Hi Kirk, Thanks for your videos – very informative. In this case wouldn't it be a more effective repair to use an angle grinder first and rout out the crack, thoroughly clean, and then apply repair material – allowing more of the product to be used and useful? All the best. Simon

    • Howdy O Kafka, this fix as many more crack fixes I do are free when I'm at a job working on other projects.
      Just because they are free, I don't hack them, I do the best I can with what I have to work with.
      However, I tell all of my customers, if you wish a valid unlimited warranty on any repair remove the entire wall, and we'll start from scratch, this idea or yours,
      is proper but I have found that the option to a free fix or one that involves paying for generally does not interest the majority of folks.
      I can repair this typical and very normal stress crack many, many different ways myself, this video was to explain how to apply a textured caulking to match a textured wall,
      for if we go into alternative solutions as we can write forever.
      best wishes,

    • My view is you are 'hacking' this repair, for want of following basic procedure. I'm sure the majority of clients would rather pay for an effective repair, rather than not pay for a less effective one. In this video your all in one scraper has hardly touched 75% of the crack, and so you're applying an acrylic caulk to what looks a quarter inch crack at most – how much material is actually going in or around the crack? Standard procedure (one which would take very little time) if you want to carry out this type of repair reasonably quickly and reasonably thoroughly, with a chance of success, you'd use at the very least use an angle grinder to rout out the crack (this wouldn't add any more time to the job, so you could still do it for free:-)) and then proceed as you have done. I do appreciate your videos and tips Kirk, but in this case I'd say you're out on a limb.

  8. question???: how would you go about fixing the painters mistake using the regular caulking for hairline cracks on a sand fine stucco finish?? paint wont hide it, especially when the paint is a really light color.
    Thanks for the very informative videos you make,

    • Howdy Robert, use more-flexx it has sand in in thus when caulked properly it does not show where the caulking was applied, I have a video coming out that shows how to cover even smooth areas that have been caulked and are visable, video out soon.

    • Good evening John, great question, most caulkings shrink if applied deeped and or wider than say 3/8 to 1/2 of and inch thick, especially the less expensive brands, the ones I show shink the least or I don't use them.

  12. Hello Kirk. I have some cracks like this in various places and im looking to color coat the whole house. Would i use this type of caulking agent to repair these cracks before color coat? What about the tape mesh? Is that for smaller cracks?

  16. fabulous! Thank-you! I live in a 1950's mossy green colored house, that my parents left to me.I can see on the back of the house where dad had been filling and touching up the paint ..now there's a super long crack all along the bottom of the back walls.I am going to try this myself,..and follow your expertise instruction! Just got to get the correct matching paint!
    Happy caulking!

    • Good evening Gabriel, this is indeed what I mean, as in the morning the wood does not get the hot sun thus it shrinks, when the hot sun beats on the wood wall it heats the wall thus once again creating expansion which pushes out the stucco.
      This action make the cracks almost invisable.

  20. Hi Kirk, love the videos. Very informative. Question, on the very fine stucco cracks or normal size one’s, are you supposed to grout them out or open them up like one would do on interior walls for plaster repair ?

  22. I have crystal white stucco and dont want to paint it. Have you ever tried sashco log jam for cracks? they have a "white white" color that looks like it matches my stucco

    Reply

    • Howdy Media, I would say if you have white caulking with or without sand to use it if you dont want to paint it.
      keep in mind 98 percent of cracks are superficial so it matters little.

  24. I used that morflexx calk on La Habra crystal white (unpainted) it is more grey than the La Habra crystal white stucco. Do you know what color paint or other product i could use to better color match the to the La Habra crystal white? note: we dont want to paint the entire house just the patch

    • kagimedia use stucco to cover your repair. If you have a hopper, spray it lightly over your repair. Use base 100 LaHabra and you should be fine. I would never use caulking to repair a crack. Good luck.

    • @Kirk Giordano plastering Inc. Thanks for the feedback. I ended up finding the correct color match. It was not La Habra crystal white stucco it was a CA brand.

      It is #10 White Color and Premix 1000 Finish Coat Stucco (white base). Ratio for Crystal White is 1 jar of color added to 1 bag of stucco mix. Super duper white.

  32. You should caulk in the Morning, The reason is before the sun has a chance to heat stucco, which can shrink the cracks, You can also use texture elastomeric caulking, listen to this man he knows what he is doing, years ago I did a job with you in Alameda, I enjoy your videos

  34. Thanks for the great video, Kirk. Can the QUIKRETE Concrete Repair caulk be painted? Not sure if that's what you used in the video, but it is listed below as one of the products you recommend.
