Mould gelcoat

[Jonathan Muller]

Hello again! The mold came out well and so did the part from the mold! But after I removed the part from the mold, various stains and traces from the fiberglass from the laminated part remained on the gelcoat of the mold. They cannot be removed with mold cleaner nor can they be polished. P.S. the mold was high gloss. Why did this happen and how can it be fixed? Can I upload pictures if needed?! Thanks

hello! I'm not at the warehouse right now! The process was the construction of a laminate in a mold! After demolding, stains and traces of the fiber threads that were laminated remained on the gelcoat of the mold!The first layer in the laminate was gelcoat in which I put 100gr/sqm csm because it will be painted and I don't care if the fiber will be printed in the final product!and those fibers were printed in the gelcoat of the mold and did not stick! Tomorrow I will be able to come with photos

On new molds if they aren't thoroughly cured the glass pattern can transfer to the surface of the tooling gel coat. This can happen from the mold laminate, or the laminate from the part.
