Re: [papercreters] 3x3 Trash Pump



Bob,
Sounds like you need a Tirolessa sprayer.  Which instead of using pressure from a pump, uses pressure from an air compressor. Google Tirolessa Sprayer and hit images, you'll see some papercreters spraying with a Tirolessa sprayer.  You need some horsepower to be effective, 10+ cubic feet per minute at a minimum of 90 psi (more is better).

I would think you would have to have a way to devert the mix back to the mixing tank when you wanted to stop spraying, other wise once you start spraying you could not stop until the mixing tank was empty.
Thanks in advance :)

[papercreters] Re: Best way to use papercrete for roof insulation?

After reading my post I dont think I explained myself very well, I assumed that you would cover your 2x6 rafters with OSB and cover that with some sort of waterproof roofing material, like granulated rolled roofing. Than once that is done go inside and attach the wire or mesh between the rafters and using an air compressor and a ceiling texture hopper then apply your papercrete mixture in layers allowing to dry between applications.

[papercreters] Re: Best way to use papercrete for roof insulation?

Have you thought of attaching chicken wire or wire mesh (which is way more expense) to the insides of your 2x6 rafters, then spraying papercrete over the wire or mesh until you get the desired thickness, don't try to do it all at once, allow drying time between coats and more wire or mesh if you want a much thicker layer?

[papercreters] 3x3 Trash Pump



I just recently bought a 3x3 Trash Pump, and would like to spray a papercrete stucco to the outside of my added addition to my house. I plan to spray a final finish of cement and sand over the papercrete stucco, then seal with exterior paint.  I have done this very successfully at the last building project I did for my former employer. But I did it with a air compressor and a ceiling texture bucket. My question is does anybody have or know of plans to make a texture sprayer out of a 3x3 Trash Pump? I would think you would have to have a way to devert the mix back to the mixing tank when you wanted to stop spraying, other wise once you start spraying you could not stop until the mixing tank was empty.

Thanks in advance :)

Bob
