In general, it is not recommended to use the same mold release agent for both concrete countertops and silicone molds due to the different properties and requirements of these materials.
Using a mold release agent designed for concrete on a silicone mold may not provide adequate release properties, as it may not properly penetrate the silicone surface, resulting in sticking or tearing of the mold. Moreover, the solvent-based nature of the concrete mold release agent could potentially damage the silicone mold.
Likewise, a mold release agent designed for silicone molds may not effectively release concrete from the mold. The water-based nature of the silicone mold release agent may not create a sufficient barrier on the porous surface of concrete, leading to difficulties in releasing the concrete countertop from the mold.
It is recommended to use different mold release agents for concrete countertops and silicone molds due to their unique properties and requirements. Using a mold release agent specifically designed for each material will ensure a successful and easy release of the final product from the mold without any damages. It is always advisable to follow the manufacturer’s recommendations and conduct proper testing before applying any mold release agent to ensure optimal results.
