Hi all,

I have just purchased my first kits from easy composites. Thanks guys for the training videos, they are very simple to understand.

In making my first part I have experienced a couple of issue and would like to understand where I went wrong.

1.  I used MDF to make my mould, I apply several coats of wax and PVA release agent but could not release the MDF part from the mould, what did I do wrong, did I need to spray the MDF part first?

2.  I had some issues with moulding my carbon part due to the tight spaces and complexity of the part, would I be better off using the vacum method for this part?

Many thanks,




Matt

For sealing MDF i have used Bondaseal G4 primer, its a moisture cured polyurethane primer that is often used to seal concrete.
It doesnt give a great finish but for a one shot mould for a repair or to produce a mould that can be worked on its fine, you will need to wax it & pva it for a decent release.
