Sanding And Then More Sanding

It has been two weeks since Tiny Refuge has been under full-time construction.  During the first couple of weeks, most of the work done was mostly at Stefan’s shop as he built the kitchen cabinets out of the leftover interior siding or panelling.  There was just enough wood to build the cabinets out of, it was very tight, it took every single plank left to build the cabinets.  It was a labour intensive process, Stefan cut and planed down each board, glued them together, cut them again to size, built doors, drawers and cabinets.  I helped out with sanding and applying wood filler where necessary on each piece that Stefan built and then sanding them again.  Once everything was sanded, we started painting the cabinets.  I bought white milk paint for the cabinets and they are finished with hemp oil.

As he was working in the shop, the interior siding was sanded to get it ready to have SafeCoat Clear applied to it.  SafeCoat Clear is a fire retardant.  It is used in the film industry and in industrial applications on wood.  If my walls were drywall or  solid sheets of plywood instead of panelling, or if I had used rock wool or sheep wool insulation, they would meet code for fire safety without adding a fire retardant.  On the plus side, it has no VOCs and it’s a Canadian product.

When I wasn’t sanding my kitchen cabinets at the shop, I was sanding the walls of the tiny house.  Alex and my mom helped out with sanding the chamfered edges each of the panels of the interior siding.  It was a full day of sanding after several days of sanding before that.  It was a long but well worthwhile process.  The walls look great.  After they were completely sanded, wiped down and the tiny house thoroughly vacuumed, Stefan came over and applied a sealant to the walls with .  Once the sealant dried, we very lightly sanded the walls again and then started applying the first coat of fire retardant.  SafeCoat Clear has to be mixed on site, and we half of it as that’s what we needed for the first coat.  That was unwise. Once mixed, the SafeCoat clear only has a 2-3 hour pot life.  As it gets closer to the end of its pot life, it gets thicker and stickier.  By the time we were applying the SafeCoat Clear to the last section of the tiny house, it was tough going.

The second coat went on much better.  The walls look so much richer after the sealant and fire retardant.
