I would try to rent that roller thing if you are using a wet blower, something that isn't that tool might just make the finished job worse than the most careless installer.
Wait a second...
Is the blower you are renting a wet sprayer? If not, and I were doing it and insulating exterior walls and a sloped ceiling, I would drywall first except the top foot, no net, pump up to the point when the insulation is blowing back too much, net over that last foot, slice a small hole in the net, pump full, then finish the drywall. Firebreaks make this a two step process per wall though.
I would prefer the wet method because the dry will eventually settle in the walls, you cant use wet on a flat or even severely sloped roof.
NOTE: let the wet stuff dry before installing drywall over it! It wont work as insulation if its wet, it wont mold if its wet, but it would be worse than no insulation.
I would drywall one side of every interior wall and wet spray to that and the inside of every exterior wall, which would already have an exterior surface. The wet spray activates the glue in the insulation preventing settling and you can get more material in wet than dry because the fibers are compressed by the wetness. And, you dont need the netting! And, you dont have to choke on powder all day! And when you shave back to the studs, the drywall goes on real easy!
The only place I could imagine using that netting (or dry cellulose for that matter) would be in a ceiling or walls that are mostly drywalled and by filling the channels up to the top. For your walls, are you planning to net the whole wall, then fill dry and drywall after? If so, that sounds like a really hard way to do this. Even worse would be netting a hole ceiling and then trying to push your drywall against that on a ceiling! No thanks!
This got me wondering, will you have someone loading the hopper? Someone shaving the walls (if wet), and reloading the hopper with your over spray and shavings?
I watched two separate companies do my building all day for every day they were here. Those machines throw a lot of insulation and are flat out exhausting to operate even for the guys that do this everyday. They machines they use are on a truck. (HUGE) Anyone doing this alone would be in great shape climbing up and down ladders and hauling insulation around and tugging on hoses.
Every one of my insulated interior walls (bath, shop and laundry for sound) were drywalled on one side and wet sprayed. All of the exterior walls were wet sprayed against brick.
My ceiling, a flat roof, was pumped in dry between the ceiling and roof except in a few strips to make it easy to shove the tube down the 20 foot wide channels between rafters. They used the netting to cover these openings but only after the long tubes were filled. After that they went back, added the nets, then pack filled into small holes cut into the net. I then had to go back over the areas with ceiling boards and if they had packed too hard, I would never have gotten the boards in.
I did the ceiling this way to accommodate the insulation installers. I hung my own ceiling and drywalled my own walls, so I could do it however I (they) wanted and make it easier and thus cheaper for the insulation installers. Personally, I wouldn't even bother doing insulation on my own, It would have cost me the same money to buy the insulation at a big box store as it cost to pay for installation and would have taken me 10 or 20 times longer than the guys that do it every day. I didn't have a job when this was getting done, but if I did and I took the few days off to watch and make sure they did it right, I still would have saved money over doing it myself.
How much are you installing? Are the rafters and studs standard width apart? My ceilings were not, requiring blown in. Cellulose is the best, but if you are only doing a small amount you might consider the recycled blue jean stuff. It installs like fiberglass sections, with all the benefits of cellulose.
Don't get me wrong, here, I am all about doing things myself. On my 96 year old building that we converted to a home and shop, I tore off (85,000 lbs
), restructured, re-decked, and re-roofed a 5700 square foot roof, by myself over 10 months...Yes this SUCKED but it wasn't in the budget so I had to do it. This required relaying the brick parapet walls that ran the 330 linear feet of the building's walls. I tuck pointed the front wall. I installed my own radiant tubing, framed and drywalled the house portion, and dug my own footings for some of the walls inside with a shovel. I wired and hung the ductwork for a multizone geothermal HVAC system because I didn't like the way the contractor wanted it done. I cut and installed my own 15 foot I-beam lintels over new garage doors cut into the brick walls. I would have done my own electric and plumbing if I could have legally. I seriously understand DIY and doing the roof and masonry probably save $80,000, but...
The insulation installation just wasn't practical or financially beneficial to do myself. For you, it may be, but since you asked for hints, my final hint would be to hire it out.
