How to make silicone moulds for concrete by silicone rubber?

Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly. 

 

Step Two: vacuum pumping

 

Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available. 

 

Step Three: Brushing cast & Perfusion Molding operation

 

FAQ of silicone rubber for concrete casting

 

Why is the tear strength of the silicone mold weak
In order to reduce the viscosity of silicone rubber and pursue a good quality, you may add a lot of silicone oil into the silicon rubber when making molds. In fact, it might have just the opposite effect. The tension and the tear strength will be reduced badly with the addition of silicon oil. And the silicon molds will be in a weak and flimsy manner.
