I want be sure my model and mold can be easy seprate from eachother so i am confused about painting my model by color or coat by filler for finishing

Hi Bob,

Can you give me a little more information on exactly what you've got at the moment (a foam pattern, an MDF buck or just a 3D model)?

Hi Matt
Thanks  ,Its a foam pattern , 2mm chock layer , filler  and  soft sanding . seems has clean surface  ,i can continue put some more  filler for last layer and then sanding ,or painting by color ,i  prefer   paint it by color  for checking the surfaces 

Hi Bob,

OK, that should be OK. If the filler is polyester filler (whcih most of them are) you will need to ensure that the polyester filler is completely cured and is no longer smelling of styrene. If it is, you should wait a while for it to fully cure off and stabilise a bit otherwise you run the risk of the filler upsetting the release agent (whether it's wax or something else).

In terms of your paint finish, it's fine to do this but please make sure you use a two-pack / 2k paint (polyurethane or acryllic) NOT a rattle-can spray paint. We have endless horror stories from customers who have used rattle-can spray paint on their patterns and then have lots of problems releasing moulds.

All the best, Matt
