Will Replicator adhere to itself?
Yes Replicator does adhere to itself, so adding more rubber is not a problem. This will enable the mold maker to build up the mold thickness in layers if needed.
Applying Replicator in Layers: Mold makers generally find that a minimum of 3/8” thickness is suitable for a working mold. Using a clean, disposable brush, the first coat of rubber should be applied in a thin layer to capture intricate detail. Use dabbing strokes, especially around undercuts, to reduce entrapped air. Subsequent coats will add strength to the mold. Let the first coat cure until it becomes “tacky” before adding the next coat. Repeat until the necessary thickness is achieved (usually 4 - 5 coats). Do not allow rubber to fully cure between layers, as delamination may result.
