When applying Stix, a bonding primer, on fiberglass, whether you need one or two coats depends on several factors such as the surface condition, the desired outcome, and the specific product instructions. Typically, fiberglass surfaces require good adhesion for topcoats like paint, which is where Stix excels. For most applications, one coat of Stix is sufficient to achieve excellent adhesion. However, if the surface is particularly porous or if you're painting over a high-contrast color, a second coat might be beneficial. Always follow the manufacturer's recommendations and consider the environmental conditions during application. If in doubt, consulting with a professional or conducting a small test area can help determine the best approach.
[If your resin won't harden, the issue likely stems from improper mixing, incorrect ratios of resin to hardener, or low ambient temperature. Resin and hardener must be mixed thoroughly in the correct proportions, as specified by the manufacturer. Even a small discrepancy can result in a tacky or soft cure. Ensure you precisely measure and mix for the recommended time. Additionally, resin cures best at room temperature; too cold conditions can slow down or prevent hardening. You might try moving your project to a warmer spot or using a heat source like a heat lamp to gently warm the area. If all else fails, you may need to remove the uncured resin and start over, paying close attention to the mix ratio and mixing process.]
Converting PVC (Polyvinyl Chloride) to CPVC (Chlorinated Polyvinyl Chloride) isn't a direct DIY process due to the chemical alterations involved. CPVC is produced by exposing PVC to a chlorine gas at high temperatures, which chlorinates the polymer. This process enhances its heat resistance and chemical resistance, making it ideal for piping applications. To achieve this conversion, you'd need specialized equipment and conditions, typically found in industrial settings. For practical purposes, if you need CPVC, purchasing it directly from a supplier would be more feasible. If you have a specific application in mind, consider consulting with a professional who can guide you on the most appropriate material and installation methods.
