Bionic Posted September 7, 2018 Share Posted September 7, 2018 (edited) Hey guys, odd topic, but I was curious if any of you have fixed up a foundation before on a home. My homes foundation is in good shape, but it has like a thin podge layer, that is starting to seperate off the blocks. I want to recoat that. I am a DIYer, but do realize sometimes jobs are better to hire for, due to time, and skill, etc. Is this just a normal coat of concrete, or morter that gets coated over the block? Any input for me? I am going to start researching online, but always like opinions from those who have experience, and are not out to take my money. Thanks. Also, possibly might add stone to it, not sure though honestly. I know with stone indoors, I added this mesh, and a skim coat of mortar with a serrated trowel....I imagine it is the same process for exterior.

Bionic Posted September 7, 2018 Author Share Posted September 7, 2018 Salt damage? Not being a wiseguy, but hows that happen? Its just a layer of concrete over the cinderblocks, that is coming off in a couple spots. I will have to take a pic for you. Quote Link to comment Share on other sites More sharing options...

Dom Posted September 7, 2018 Share Posted September 7, 2018 Parging is easy as it looks.A trip to Lowes/homedepot all you will need is some masonary sand and some portland mixed with water and mixed until semi smooth trowel on.I would remove all loose materials and recoat entire foundation.Also roof gutters will help 1 Quote Link to comment Share on other sites More sharing options...

Thank you for the info, gutters are actually on my to-add list. That is a project, I can absolutely handle. I really appreciate the info.

Dinsdale Posted September 8, 2018 Share Posted September 8, 2018 Just a suggestion; If you re parge after removing the old stuff; seal the top edge where it meets the plate with an elastomeric caulk like Sika Flex or similar. Water intrusion is a problem there, and will get behind the new surface, freeze, and expand. Quality material will result is a longer lasting job. Renting a demo hammer and a wide blade chisel often called a "scaling chisel" makes short work of prepping a fresh surface. 1 Quote Link to comment Share on other sites More sharing options...

Expand I have similar caulk on its way for the checks in the logs actually, so I know what your talking about. So, remove all the parge, and start fresh? I really do need to get some big gutters up. That is great info, and very helpful, I really appreciate it. Quote Link to comment Share on other sites More sharing options...
Bionic Posted September 8, 2018 Author Share Posted September 8, 2018 Dinsdale, if I wanted to add stone, would I add a wire mesh type screen like I did inside my house, etc? Or when adding this parge do you make the mixture firm enough for stone? Or am I completely off here, and its and entirely different process? Also, do they sell a dye for adding to this parge? This way, you can avoid painting the foundation? Quote Link to comment Share on other sites More sharing options...
Dinsdale Posted September 8, 2018 Share Posted September 8, 2018 (edited) Easiest first, yes you can dye a parge mix. Need to do a careful measured mix to be consistent, that includes dampness of mason sand being used. Doing up to natural changes in foundation will help that, ie from corner to front steps or corner to a window hiding next batch line under the window. Yes I would spall off all the old surface, judging by pics it'll come off in sheets. Scratching up block won't hurt it and will give fresh surface. Wash and apply bonding agent. Adding stone... Real or cultured? Cultured is thin and light. I would say much easier for home owner type installation. Do a good job on prep and yes, you could add later. Now if the substrate block has issues, soft, cracked structurally , yes I would most likely add mesh. Corners are expensive, but stupid easy. Real stone? Need to add ledger, steel with appropriate fasteners. I'd feel better with mesh fastened to wall for a home owner job. Does it need it, not if working correct; but this is why I almost always regret answering these threads; I must be bored tonight. All kinds of skill levels out there and opinions. My brother the engineer thinks I don't know shit after 30 years of custom home building any dummy can do it; the chimney he flashed on his roof leaks, the one I did? Not so much(my SIL told me this, LOL) There a bunch of work in real stone corners depending on pattern to make it look decent. Shitty is always easy and quick. Either case a decent flashing detail or cap has to be thought of at top edge where you meet the bottom log. I don't like relying on caulk for that, the surface is too wide and full of potential fissures, so I'd be inclined to come up with a copper flashing with some pitch detail or a stone cap but lots on linear inches to deal with there and you pay by the inch for rocking/flaming edges.

Expand Yeah, i see what you mean by dying, unless i premixed 500 gallons of concrete, it will be tough to perfectly color match, bad idea for a picky guy. This is exactly why I ask around... For stone, probably fake stone that looks real. Its really just a thought at this point. I did a wall in my home, inbetween the post beams, I installed, it took forever, because it was my first ever stone project. Pic added. I know what you mean, at work we added a stone cap where it met the cedar impressions, you need that overhang, is what you are getting at, to cover that seem. With stone, with the amount of surface area, of a foundation, I would end up hiring for that, by the time the complete the job, I would be only starting to mix the concrete. Sometimes the time saved by hiring, is worth it in my opinion. Thanks for the post! 1 Quote Link to comment Share on other sites More sharing options...

Plus look for a bonding agent admixture to add to your mortar mix. Also, make sure to wet the CMU so it is damp before applying the parge. It will help with the bond and ensure the block doesn't suck the water out of parge.Sent from my SM-G930V using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

I used that coffee can with water, and I wet the wall, then the block before buttering the block with mortar. Thank you for the tip, its a good reminder.
