Camper gets cozy: spray foam insulation

Spray foam day!  Over a year after initially inquiring about the qualities of this soy-based spray-on insulation typically used for sealing basement walls, I finally had the guy over to spray my camper.

The contractor came with a big self-contained work trailer with his compressor/engine/miles of hose and drums of product.  He fired it up- it was very noisy, sounded diesel, and took some time to prepare.  I was too tired to get nosy but I gathered that there was compressed air, then the liquid product that must be pumped or pressurized somehow, delivered in two hoses and mixed at the gun as it’s sprayed on the walls.

The very beginning

A third hose is supplied air to his breathing apparatus.  He suited up and got into his breathing mask, dragged all the hoses from the trailer to the camper, and began.  He knelt on the floor and did systematic side to side passes with the gun, occasionally doing a depth check by stabbing it with a screwdriver.  He sprayed over the walls and wheel wells and ceiling until it was all one puffy peach coloured surface.  It didn’t take very long.  It had no smell, inert as soon as it dried (almost instantly).  Continue reading Camper gets cozy: spray foam insulation

Camper reno: adventures in fiberglass

Before the camper could be insulated, there was some work to be done.

First, it needed to be dug out of the snow.  I almost got my truck stuck in the axle deep mud hiding under the dense old snow. (This was March), the shoulder season of melt water almost flowing underneath heavy snow .  Plus it rained mid-mission, so it was absolutely the worst timing for excavating the camper.

The original  interior surface layer was a sort of textured beige vinyl with a quarter inch of foam backing glued on to the fiberglass surface.  A whole quarter inch of “insulation”, wow!  Either time or the heat or the original glue had that layer so stubbornly adhered to the fiberglass that when I was tearing it off originally, only the vinyl came off like wallpaper, leaving the meat of the foam behind, which is black.

So I had to finish scraping out the vestiges of black foam with a drywall knife.  Sometimes it would come away in satisfying chunks, sometimes only in crumbs (which had a great knack for finding cuffs and collars.  At any rate, it was tedious, slow, and tiring.  A never ending task.  Naturally, the overhead stuff was the most difficult, probably baked on by 40 years of sun.

Mostly done chipping away

Next, the fiberglass repair.  This was my first experience with fiberglass resin, and I have to say it put me over the edge.  I used to think Acoustiseal was bad, and wire fencing worse.  Now, what I wish on my worst enemies is that they will someday have to do overhead fiberglass resin repairs.

Officially, the most diabolical product EVer.  Continue reading Camper reno: adventures in fiberglass
