    Anyone have a solid cost estimate per square foot or meter to lay up fiberglass on a mold?

    That would depend entirely on the type of glass and resin being used. Without specifics I dont think such a solid estimate is possible

    Fibreglass tesin costs about $5 /litre and the cloth is basically twice that, so a metre built will be about $15/metre square per layer. Depending on the area and the thickness you can work it out from that.

    Can you explain that more?

    Is your glass cloth 10 $ per m2??

    ......correct......$5 for resin....10$ for glass...together they are about $15/ metre square.

    One liter of resin will be one metre square if it is 1 mm thick.

    ...the resin to glass ratio will be about 50% till you get better at it.

    Yes


    go to the online shop of your choosen supplier and start calculating.

    The reinforcement weight per area (sq ft. or m²) is almost always equivalent to the resin needed to saturate it in a (good) 50% / 50% layup.
    A common hand layup, done by a novice rarely comes to that ratio. More likely 60% resin 40% glass is the result. Make your calc.s accordingly.

    So, a 5$ m² glass of 200 gram m² and 200 gram of the resin (price per Kg ,given 10$), = 5$ + 2$= 7$, that is the price for a good 50/50 layup.

    Those prices are just to make the calculation easy! I can buy a Kg of poly resin at a fraction of that and some glass fabric at 1$ m².

    Regards

    For CSM it is different: A 450 grams CSM will eat 1 kg of resin, and will be 1 mm thick.

    CSM is about 3 euro / kg (so 1,35 / m2) and poly resin about 3 euro / kg as well.

    Which make a CSM laminate about 4,5 euro per kg.

    In a production environment, all consumables cost roughly the same as the resin used (gloves, brushes, rollers, etc etc)
