Steve,
Thanks for the good info.
It is true that the s-glass 8 plait satin weave we use is hard to wet out
from the top. The trouble is that when resin is applied on top of the cloth
it
tends to seal the weave and trap air beneath. In a perfect world we would
always wet out the part and set the cloth on the wet out surface. That way
you squeegee the resin into the cloth from the bottom and chase the air out.
I use this method on all small parts.
On large surfaces when working alone, it is often impractical to wet out the
part before applying the cloth. When you are forced to apply the resin on
top of the cloth because of time considerations, I've found that, once you
have a small wet out area,you should always dump the new resin on top of the
wet
out surface and squeegee it onto the dry cloth surface with some pressure.
This process helps minimize the amount of trapped air a bit.
Thanks again for the input Steve.
Best regards,
Bram
