Would this kit be enough to make a mold that is 12"x 2" inches? I want to make a mold of a Graphics card shroud.

Thank you for your question. Working from the online calculator (https://www.smooth-on.com/support/calculators/) we reckon around 2kgs of product should do this. We would suggest getting a little extra though just in case.

Can you add colours to it?

Yes, as long as you use a Silicone Pigment such as Silc-Pig then this will not be a problem.

can this be used to cast concrete planters? if so whats the shelf life?

Thank you for your question. We would recommend something like the Vytaflex Polyurethane Rubber to cast concrete as the Eco-Flex is a super soft Silicone.

hi would i have to prepare plaster of paris cornice with anything before i use the silicone

Hi there, we would need you to be a little more specific on what you are using the EcoFlex for. Could you email us at info@benam.co.uk so that we are able to help you further. Kind regards, Bentley Advanced Materials
