Hi Y'all,
We have GALLONS of paint that we've collected from the recycling center that may or may not have been frozen.
When we paint a first coat on the papercrete, we use a Lot of paint.
From what I find online, the only problem with pain that has been frozen is that is can be lumpy. Lumpy paint isn't a problem.
Would there be any other reason we couldn't use re-purposed paint?
Thank you thank you thank you!
Alaine

[papercreters] curing problem
We just looked at a steel frame papercrete home that is for sale. Unlike other papercrete homes that I am familiar with, this one is aprox three stories tall. It's gorgeous (absolutely gorgeous) inside but there are huge cracks on the outside starting at the roofline and continuing to the base. The realtor said its a curing problem.
My immediate thought is that this is going to result in a toxic home due to mold issues, but I am new to this so could be overreacting.
Can anyone out there tell me if this is a fixable problem or a lifetime of headaches? The price for the house is unbelievably low, which is the only reason we could entertain buying it. But if it is not fixable, well, obviously, the cost is too dear.
Thanks so much for your help!
Debra

Re: [papercreters] Re: PC Insulation
The other consideration is speed and agility of the mixer. If you have a tow mixer (or stationary) it will only mix up about 200 gallons at a time. It would take about three or four batches to fill a wall section 12" deep with a 4' X8' section of wall. I would want to pour around the building so the whole thing goes up evenly. I said 8" in an earlier post, only because one mixer load would fill an 8" X 12" X 8' section. One could easily make it 10", 20" or the whole sheet.
In my experience, I have not ever been able to do 4 tow mixer loads in a one day period. There always seems to be something that gets in the way. But, others may be able to do that easily. It is a problem with getting the paper weighed out and ready, the water ready (4 loads would be about 1000 gallons of water), the sand and cement. With no break downs and everything ready you could conceivably do a load every hour depending on how you get it out of the mixer and how hard it is to pour into the forms. You'd think you could do this before lunch and another 4 after lunch, but it rarely works out that way.

Slip forming was RE: [papercreters] Re: PC Insulation
I live in a very dry environment so am not worried about mold but I did notice a few years ago when I poured a slip form wall right before winter and left the form on until spring there was a small patch of mold on the wall. So I really can't advise those in a wet climate, but maybe if you add some borax to the mix it would eliminate the mild possibility.

Yes.
>> Does it get over 100 degrees Fahrenheit for protracted lengths of time? <<
No, fortunately.
I like the idea of slip forming as the studs are currently open.
But I was concerned about possible water damage caused by water running from the slurry into the vapor barrier/panel that attaches to the outside of the stud, under my aluminum siding.
I had thought about stapling some plastic drop cloth to the wood prior to pouring, but I wanted the wall to breath.
Any ideas?

[papercreters] Re: PC Insulation
Is there a reason to only use 8" strips of ply, rather than the whole 4x8 sheet and pour anything upto 4' depth in one go?
