fast plastering.

Hello again all you DIY weekend plastering warriors today we are giving a few tips on fast plastering O.K. it’s on fast forward but Plaster or stucco over the dreaded drywall or fiber board is always a drag.
Because a fella asked me to about three days ago to explain this board and why it was used.
I took this project to answer his question, thats the kind of fellow I am.

Some boring history, gypsum and fiberboard sheathing can and has been used for a solid backing for stucco around the 1950s some say fiberboard has been around for hundreds of years while gypsum board, sheetrock or drywall (all name means the exact same thing for the gypsum products) has been around from around the 1950s. Both were better than just studs when applying stucco to a home as they had insulation and sound proofing abilities.
However and here’s the part old Kirk’s familiar with, both are a real drag to tie into if either of these boards gets wet, they become really soft and most time, for say repairs of water damage or window and door replacement, it’s a real drag to get a new water barrier under or over it.

Most times it’s just as difficult as a stud wall with stucco over it.
Gypsum sheathing boards are usually white in appearance in the center, with many different paper coatings.
Both boards were used years ago generally for exterior purposes while gypsum is used for interior purposes as it was sold with a water-resistant paper covering on its face. It was sometimes attached to studs to make a solid backing for stucco or other finishes for brick veneer, it is outdated for a reason!

Fiberboard is usually made from recycled newspaper, wooden fibers, and other products that are glued together. fiberboard can has has been be used for sheathing, as it also provides sufficient backing for stucco at one point in time. early 1900 to 1950 as a rule, of course if a fella today finds it in his garage in 2015 he might still use it. Stranger things have happened!

FYI, anyone interested in the material we used tin this video that would adhere and stick a solid inch at a time, it was Eisenwall cement plaster made by Rapid Set.
This cement plaster can be applied up to 6 inches thick back to back same day.

Eisenwall is a premium hydraulic cement for exterior plastering, one coat stucco and wall repairs, this material requires a citification for good reason, (or used to) it really requires a lot of time in to understand how to mix and apply as it sets REALLY FAST (in 15 minutes to a half hour) unless you add retardants, and is incredibly strong, so strong that if you don’t apply if just right it’s not coming off, even with a sludge hammer.

Rapid set also sells a simullar cement plaster at all the Home Depot’s and Lowes, hardware store, just not this brand, the rapid set you DIY’ers purchase at these hardware store’s already comes with the sand, you just add water. Much more user friendly.
This Eisenwall, we must also add the sand, plus the water, it’s sold at Westside Building Materials and many of the professional plastering material yards, not sure if a citification is still required.

  6. hey Kirk got a question!!! so we are getting orange peel in our home tomorrow morning and my wife is asking why cant we add the paint to the hopper gun with the orange peel. is it possible to add the paint color to the orange peel? thanks guys!!!

    • Morning jnixongo00, I don't understand what you mean getting the orange peel?
      You mean someone is going to use a hand hopper to spay on a plaster coat or the popcorn ceiling that is usually Perlite or any type of aggregate and gypsum mixed?
      It is possible to add paint to this, but it's a nightmare to get the color you really desire for many reasons.
      Cheers!

    • Morning Peter Moring, man you were good, I think this fast setting saved 10 minutes each time of viewing that might have got a bit to boring, but what was not shown was how well the tops and sides adhered to gaps over 1/12 inch deep with this professional material.

  19. Hi Mr Giordani. I Love watching your videos! I am trying to replicate the original smooth, slightly sandy stucco interior wall. We had to do a complete renovation and I was wondering if I could use stucco as a finish on the new drywall in my kitchen? I did a practice piece and it looks really good but will it be stable?

    • Good evening Dude, you can google your question if you get 50 replies all will contradict one another.
      My job in this video is to waterproof the window patch not to allow it to breathe or absorb moisture.
      You are referring to a 3 coat cementitious finish, these three coat color integrated finishes are designed to breath, thus when it rains the walls darken, when dryer condition occurs they return back to their original finish, like a brick.

      The building will probably breathe if you open windows , or doors ? i know sounds obvious, but it will work. the construction will settle and will not need too much expansion and contracting, unless you live where there is a lot of change in temperature,. even if there is change in temp, it should settle and will stay firm and strong. Im doing a 3d animation of a building i want to build. will upload it.

  22. Hi Kirk: I just started checking out YouTube and I find your videos most helpful! Thank you. I got a question for ya… I am helping a lady out with an art studio add on (which is basically a fully enclosed porch) which I have since insulated and replaced some very rotten wood siding. Being in So Cal, its all termite damaged and we have taken precautions to remove the pests and also replace the siding. I used Hardie Backer cement board to replace the siding. Her house is stucco finished and I want to also stucco her art studio to make it look like it is part of the home. However I find there are very little videos on how to stucco over the cement board. I have purchased a metal meshing to install if necessary, but would you recommend I use any mesh or should I just go get the paper backed chicken wire and go forward from there? Thanks again!!! Your amazing at what you do.

    • Howdy Ryan, depends, did you install a moister barrier under the Hardi board if so attach 17 gauge stucco netting over the Hardi board into the studs, then stucco.
      If you did not install a moister barrier than you can use the paperback wire that is impregnated into the paper.

    • Thanks Kirk. Would you say the wire netting is critical? My clients brother (former contractor and window/door specialist) said I should just mud over the Hardi board. There is a paper barrier behind the board.

      Reply

    • Howdy Ryan, depend on the situation, stucco netting over paper is necessary to hold the stucco.
      Stucco naturally adheres to most cement boards by suction with proper hydration.
      That means mist the boards with water from your garden hose, "not dripping wet," but just a mist, then apply the stucco to it, this, when done properly, forms a strong mechanical bond.
      However, yea, theres more, if you have many seams these will crack if you don't use a quality mesh tape designed for this board.

    • Howdy Ryan you can use mesh 3.4 wire if you applied a moisture barrier behind the hardie board. if you did not install a moisture membrane you will need paperback stucco netting as hardie board is not waterproof.

  24. Kirk… Thank you so much for sharing your craft… I have been watching for over 2 years. Question: I have a issue with Hardie Fiberboard sheets that were used as exterior siding and are now pulling apart creating leak paths. The field joints were just caulked and nailed, no metal flashing at ANY joint 15 years ago after Hurricane Ivan. I now have serious water intrusion issues due to the board literally pulling off the studs, cracking the board, and creating open seams resulting in water intrusion. The only thing that seems to whether the storms on the beach here is concrete and plaster products. I need to ask a stupid question. I am trying to save the existing siding for cost reasons, and just seal the seams or skim coat all of the existing siding to create a NO SEAM finished concert ./ plaster look. I am going to have to remove 3 windows that are also leaking INSIDE due to shoddy workmanship by crappy contractor. When I remove the windows I will surely have additional cracking and breakage of the siding. So what I want to do is nail the siding back to the studs to make it letdown, then apply fiberglass tape to the joints and them use some concrete or plaster product to mud the seams. I am also interested to know if I can skim coat or plaster over all the siding creating a solid concrete look. I want to seal the seams and add structural protection using this method. Is that something you can recommend? I want to permanently seal all seams. A more costly option will be to remove all siding on this 2 story home then remove all the plywood backing board, than install cement board verses siding. (like the Knauf Aquapanel Exterior Cement product / process… Need recommendations feel free to hit me up at Matthejd1@yahoo.com or reply here… much appreciated.. .Jim In Pensacola Beach Fl…. Help me out and when I finish this remodel I have a week on the beach free for you and the family ! Later man..
