You are using clear silicone so you can see if you have any air bubbles trapped in your first coat. You don?t want any, so try to get it mixed as smooth and even as you can. Don?t stir any more than you have to, stirring can create air bubbles.
You now have between 15 and 45 minutes to spread this over your Master. I use a soft plastic spatula about 1 inch wide. This seems a bit small bit it makes it easy to keep the silicone coating even. Make the first coat thin, about 1/8?. It is the most important coat. This is the one that holds the details. The working time depends on temperature and humidity. If it is hot and warm you have 15 minutes! In a cool, dry place you will have 45 minutes or more. You may want to try spreading this on some throw away masters before you try to do your first ?real? mold.
