A mate glued some Corelite PVC H80onto a paulownia/cedar blank which I minimally shaped. It’s an experiment and I planned not to glass it. On a trial in small waves it went ok. However, the Corelite becomes like abrasive after a while. I want to keep it light. The foam can soak up resin so I was thinking one option would be to get a layer of glass with minimal resin vacuum bagged as a skin. This would be structurally the best option. Another option is to glue EVA boat deck grip or something similar, as padding. No structural strength but light.
I could ride it again in bigger waves and see if it flexes too much, which would suggest the need for a thin layer of glass.
Anyone in the local Brisbane area able to vacuum bag a layer of glass on it? Due to hip surgery I’m not driving too far at the moment.
It’s unclear to me exactly what you have and exactly what your goal is. But it sounds like this might be a candidate for a prepreg application, to minimize resin soaking into the foam.
I haven’t tried it, but you can probably find info in the archives, its been discussed in the past. And no vacuum is needed.
Maybe someone can chime in with more info, but the process I’m talking about involves wetting out the fiberglass cloth on a glass surface, then rolling it up and moving to the blank, where it is unrolled onto the blank, and smoothed out. This eliminates a lot of resin being absorbed by the blank.
Thanks. My original goal was to just do something really simple, wood on Corelite, no glassing, but Corelite just rubbed my elbows too much. I had considered something like you suggested, but hadn’t thought off wetting the resin over glass.
