Answer: To mix Smooth-Cast 300, thoroughly combine equal parts of Part A (resin) and Part B (hardener) by weight. It is essential to stir them well for 30 seconds to ensure a uniform mixture. This careful blending activates the curing process, leading to excellent results. Always work in a well-ventilated area and use appropriate safety equipment. The clarity and color of your final product can be affected by improper mixing, so be meticulous for the best quality outcomes. -
Question:
Is Smooth-Cast 300 safe to use?

Question:
Can I use Smooth-Cast 300 for outdoor applications?
Answer: While Smooth-Cast 300 is known for its durability, it is not specifically designed for prolonged outdoor exposure. If used outdoors, it may be prone to discoloration or degradation over time. For outdoor projects, consider applying a UV-resistant topcoat after curing. Many DIYers use it for decorative items, but adding an external protection layer is recommended for longevity. -

Question:
Can I use Smooth-Cast 300 for deep pours?
Answer: Smooth-Cast 300 is not recommended for deep pours exceeding 1/2 inch due to potential heat buildup during the curing process.
