RE: [papercreters] Need suggestions for waterproofing

We had a discussion a while back about adding latex paint to the mix or painting the finished papercrete with it. I am in New Mexico and have had my papercrete standing out in the weather unprotected and not waterproofed in any way. I think our climate is about the same. We have tremendous thunder storms but they are usually short lived. The water mostly runs off with very little soaking into the papercrete When it rains the pcrete gets wet but dries out very quickly.
I do not have a roof on yet but am thinking that if I use a thick layer of papercrete and slope it it will be ok not to waterproof it. The unknown factor for you is if the roof of your trailer will hold the weight.

I will be watching the responses to your post because my mother lives in a trailer with a deteriorated roof and I had not considered putting papercrete up there.

Subject: [papercreters] Need suggestions for waterproofing

Hi,  we're in the process of making thinner block PC panels (3 inch thick) to cover the roof of our mobile home to help keep the sun from cooking us alive and tripling our electric bills (western arizona desert) and I need an inexpensive way to waterproof the panels.  Since we do get some occasional t-storms during July/Aug with heavy downpours, without waterproofing they could absorb quite a bit of water which would add quite a bit of weight to our roof.

 

I checked the price of cool coating and it's a bit expensive.  Any good suggestions?  I was thinking of just coating the outsides of the panels but if there's something I can add to the mix so that the panels won't absorb rain water, that'd be even better.

 

Thanks!

Terry
