Hello all,

I have recently purchased some Xencast P60 and have cast some pieces with 5% polyurethane pigment. Unfortunately I'm getting lots of tiny bubbles stuck to the surface of the pieces and sanding makes them stand out even more. 

I'm wondering whether it's air introduced during mixing or gas generated during curing due to moisture contamination. If it's the latter case, could someone recommended a moisture scavenger or some other solution?

Attached are pictures of an unprocessed piece and a finely sanded piece (1000 grit).

Many thanks for your advice.
