Re: [papercreters] Re: Ed Conley - Project Photos / Followup Mail

Tricky question. Would a non PC house suffered from mold under similar circumstances?


A non-pc house would probably not have been subjected the large amounts of moisture that PC building uses. If a standard post and beam home were given the same levels of humidity and air flow restrictions it would also mold. 

I'm not sure how much cure time was allotted for the blocks. In my own experience blocks like to cure a really long time to get almost all the moisture out. You may be able to get a block 90% dry in a few days, but that last 10% can take a weeks or months depending on weather. 

Papercreters tend to get things really wet when building walls. Spraying water on the blocks to between mortar layers to get a monolithic wall. It takes a while for that water to leave. 

I think the practical lesson to learn from the mold possibility is related to building in a urban environment. What will you do after hours for ventilaton? Slurryguy has some good tips on rapid dehumidification. If the windows and doors cannot be left open do you have enough ventilation? Do you need to store the blocks inside as well to prevent theft? Will you be dragging your tools into and out of the building each work day? Things to consider if you are concerned about theft and building a home.

True, Mikey. I got the impression somehow that mold was unusual for
his area. Do you think a non PC house in similar circumstances would
have suffered the same fate? Or was the PC not allowed to cure
thoroughly? Just looking to learn.
