Step 2: Get Your Mortor

for our rock wall we needed six 80 pound bags of Sakrete Mortar/stucco type S mix

you will need High Strength!! do not attempt this project with medium strength or anything other than the high strength stuff, we tried it with medium strength and the stuff does not work well.

you will also need a five gallon bucket for the mixing of the mortar.
<p>Looks good, how would this work for an exterior wall though? I have a project that needs an exterior rock wall and am looking for ideas</p>
<p>A nice easy instructable, I would be sure to check your floor beams to be sure it can hold up the weight of thewall. I have also used chicken wire fastened on the back wall to give the concrete something to bond to. This will help prevent the wall from tipping over when you are putting it up.</p>
Hello, I love your wall and am hoping to replicate something similar. However, I dont understand what the &quot;tiedowns&quot; are and the purpose for them. Do you have any pictures of them and the way you put them on the wall? Holding rocks on? ???????? clueless in chugiak, alaska. THANKS.
very nice, giving me ideas :-) <br>
heh heh I came her looking for a different type of Rock wall....
My friend's dad built one of these. He included one or two realistic-looking lizards in among the rocks! They were so cool, and the were unobtrusive, so you didn't see them until you had looked at it a while. Fun!
You need to reposition your hanging baby roaster, it's rather off-centered. It looks very unprofessional when it's not hanging directly above the wood stove. Plus, you can't truly replicate that mesquite flavor after the heat diffuses away from it.
Nice job.<br/><br/>There might be a few with construction trade experience that will say:<br/><ul class="curly"><li>I hope you rebuilt the wall with the proper vapor barrier installed with the insulation.</li><li>Make sure you tape the backerboard joints with the proper alkali resistant fiberglass tape(not the drywall kind) to keep joint expansion from popping the rocks off your wall.</li><li>You could have used thinset to adhere the rock to the wall. And you do need to moisten the backerboard so it doesn't draw all the moisture out of the thinset as it cures. Mortar is more for filling in joints a vertical build like piling rocks or bricks on top of each other. That is why you need the metal ties to keep it from pulling away from the wall.</li><li>You shouldn't add water to a batch of mud after it has &quot;slaked&quot; or started its chemical reaction and begins to cure or dry, you will only weaken the mix.</li><li>You should use a notched trowel to &quot;burn-in&quot; the thinset to the wall and back butter the rocks/stones to help the adhesion. The proper size notch assures that the right amount of adhesive is there after you smush it up on the wall. A big glob of mud will take a lot longer to cure.</li><li>You let the wall set up and then go back to grout inbetween the rocks.</li><li>You can purchase spacers or improvise to keep the grout line consistent. You can put up a string line or use a 2x4 or level to keep the face even.</li><li>They do sell veneer-type rocks or even fiberglass fake rocks to install on a wall if you are worried about weight.</li><li>johnbridge.com has a great forum for details on masonary and tiling subjects.</li></ul>
Very nice instructable. One thing I would recommend, though, is that if you can get your hands on some cultured stone that may be a better option. And you may be able to get it with this same budget. Back when I was landscaping we did a number of new homes in some very nice neighborhoods. We would get there the day or week after they had just put the finishing touches on the house, and in this area that means cultured stone. I'd say that about 90% of the time they had a 1/3 or 1/2 pallet of stone left over that usually just got thrown out. Cultured stone is lighter weight, so it would make building a wall easier, for sure. Find a new housing development and see if you can make a deal with the contractors. Cheers! -DMC
it would be nice to get some more detailed pictures...especially of the antique nail bit
Very nice job and decent instructable. I'm considering the very same project, but was wondering something: Aren't you worried about all that weight? Is your floor joist hefty enough for all that added mass? I also assume your walls are standard 2 x 6 correct? You may want to explain to folks how/why the metal tie downs work. I'm familiar w/ them from past use, but I'm sure a lot of folks won't understand why you need them. Nice wall and nice instructable! j
Looks like a great job, well done... One thing that might be handy for the larger rocks is cobbling together a vague hoist like assembly out of some pipe and castors, to make getting them in just the right place easier... Of course that's only if you start to get lazy...
