Two years ago we redid the icebox
. Poured 2-part polyurethane
inside the previous (cavernous) enclosure, into which a transparent plastic container was sunk, cold plate and thermostat fitted. Overall, very pleased with the result.
Today we discovered mold
, growing between the transparent enclosure and the insulation
layer, where there is some airspace (we couldn't achieve a perfect fit). Still minimal (a couple of spots 4 mm wide). The cause is obvious -- humidity infiltrates between the enclosure and the insulation
, probably through the screw holes (4 screws secure the evaporator). The fix, less so.
1. Other than some "yuck" factor, anything to worry about?
2. The boat
will spend close to 2 years on-the-hard starting in a couple of weeks. Anything we can/should do to avoid propagation and possibly kill the spores? (the ice-box lid is kept in an open position, so we assume that everything will progressively dry. But in the meantime mold
will probably expand...
3. If I rebuild
the enclosure: (1) is there a safe biocide that can be used to line the interface between the insulation and the plastic/epoxy container; (2) we do not believe that the mold creates any health
hazard since the container can be cleaned easily. No spoiled food
or any indication that something is wrong. Would an opaque container be a "fix"? (i.e. yeah, yeah. There's mold but we don't see it so we don't think about it. After all, our cavernous enclosure was stainless. And unsealed. Probably completely surrounded by mold.)
4. Anything else?
