j Group: Forum Members Posts: 2, Visits: 2	Good morning. I have created a plaster mold of a face and I want to put carbon fiber on top of the mold/face and be able to remove it once the carbon fiber has dried out. What product do I use to ensure that the Carbon Fiber will release from the plaster face/mold? Which Carbon Fiber Starter Kit do you recommend I use? The face is about 1 meter high, 1/2 a matter in width and about 30 Centimeters in depth from tip of nose to ear. Thank you very much for the help and advice.

Hi Johnny, given the size of what you're doing and the materials you're working with (plaster), the best way to get a good release of the carbon fibre 'skin' off the plaster mould/former would probably be to spray the plaster with PVA Release Agent. PVA sprays well through a normal spray gun and you can use the spraying process to build up a good reliable layer. A wipe application would not be recommended because you can't wipe over an area that already has PVA on without accidentally lifting it whereas spraying PVA doesn't have this problem. I think this would be an easy and reliable solution for you. Make sure the plaster is fully dried of course, otherwise you'll have a few issues!

This was very helpful. Do you think the XCR Carbon Fibre Skinning Starter Kit would be the appropriate kit for me to complete this job? Also can I just let the Carbon Fiber dry at room temperature? I do not have a vacuum for this. Again thank you very much.

Skinning is usually a single layer process where as for a simple facemask you would probably want 2 layers for it to have a reasonable level of stiffness. You would not need vacuum for this work and also it is fine to cure at room temperature. Warren Penalver Easy Composites / Carbon Mods - Technical Support Assistant

t Group: Forum Members Posts: 59, Visits: 278	2 years ago I did a fighter jet model fuselage in plaster as a template. I thinly painted the dried plaster with wood hardener (similar to the S120 Advanced Board & Mould Sealer), then spayed it with 2k epoxy primer, sanded with 1200 wet paper and used release wax and PVA The resulting mould came off the template without big issues
