Mixing Guide
 |
Take the A and B component of the same shore type and read the mixing instructions carefully. |
 |
Weight and mix both component in a mixing container. |
 |
If you want so coloured silicone, add some dye. Around two drops per 200g should be enough for a bright colour. |
 |
To remove the bubbles, put the container into the vacuum-chamber and close the lid. Add some paper towels to prevent spillage. |
 |
Close the left valve and open the right one (like shown in the picture) and turn on the vacuum pump. Do not go over -1 bar. When the desired vacuum is reached, close the right valve, wait till the bubbles have popped (slightly moving the chamber might help). Then open the left valve carfefully. |
 |
The silicone should look smooth like this and is now ready for pouring. |
