Customer Questions & Answers

Question:
What is the True Composites Fiberglass Resin 4 Gallon Kit used for?
Answer: The True Composites Fiberglass Resin 4 Gallon Kit is primarily designed for repairing and laminating fiberglass structures. This kit includes a high-quality polyester resin along with MEKP hardener, making it ideal for boat repairs, surfboards, and other marine applications. The marine-grade quality ensures durability and resistance to harsh environments, making it perfect for outdoor projects. For example, if you have an old boat that needs a hull repair or want to create a custom fiberglass part, this kit will provide the necessary materials for a sturdy, long-lasting finish. -
Question:
How do I mix the True Composites Fiberglass Resin with MEKP hardener?
Answer: To mix the True Composites Fiberglass Resin with MEKP hardener, follow a 100:2 ratio; this means for every 100 parts of resin, add 2 parts of MEKP. Thoroughly mix both components until you achieve a uniform consistency, ensuring the hardener is evenly distributed throughout the resin. Proper mixing is crucial as it influences the hardening process and final properties of the laminate. For instance, if you're working on a boat repair, ensuring accurate proportions will help achieve optimal adhesion and strength in the repaired area. -
Question:
Can I use this fiberglass resin kit for indoor applications?
Answer: Yes, the True Composites Fiberglass Resin can be used for indoor applications such as crafting and model building, provided there is adequate ventilation during application. Indoor uses may include creating custom furniture or crafting durable items like decorative bowls. However, it’s essential to be aware of your working environment to avoid inhaling fumes. Use safety equipment such as gloves and masks while ensuring your workspace is well-ventilated to maintain a safe atmosphere. -
Question:
What materials can I laminate with this fiberglass resin?
Answer: The True Composites Fiberglass Resin is versatile and can laminate various materials, including fiberglass cloth, mat, carbon fiber, and even wood. When used with fiberglass cloth, it creates a strong and durable composite structure. This is particularly effective in marine applications, where increased strength and water resistance are critical. For instance, if you want to reinforce a wooden structure, layering it with fiberglass using this resin can significantly enhance its durability against moisture and physical stress. -
Question:
How long does it take for the fiberglass resin to cure?
Answer: The curing time for True Composites Fiberglass Resin generally ranges from 1 to 3 hours, depending on environmental conditions and the hardener used. Warmer temperatures tend to speed up the curing process, while cooler settings may prolong it. It's essential to wait until the laminate has fully cured before applying additional layers or using the finished item, as this ensures maximum strength and adhesion. For best results, avoid handling or moving the item until it hardens completely. -
Question:
Is this fiberglass resin kit suitable for underwater applications?
Answer: Yes, the True Composites Fiberglass Resin is marine-grade and can be used for underwater applications, such as repairing boat hulls or submerged structures. Its waterproof properties ensure that it can withstand constant water exposure without compromising its integrity. If you are working on underwater repairs, ensure that the surface is clean and free from debris before application; this will enhance bonding and long-term durability of the repair. -
Question:
What safety precautions should I take when using this resin?
Answer: When using the True Composites Fiberglass Resin, it’s important to wear appropriate safety gear, including gloves, goggles, and a respirator to avoid inhaling fumes. Working in a well-ventilated area or outdoors is recommended to reduce exposure to any potential hazards. Also, avoid skin contact with the resin as it can cause irritation. Proper precautions ensure a safe application experience and protect you from harmful substances while allowing you to focus on your project. -
Question:
How do I clean tools and brushes used with this fiberglass resin?
Answer: To clean tools and brushes used with True Composites Fiberglass Resin, it's best to do so immediately after use while the resin is still wet. You can use acetone or a solvent specifically designed for cleaning fiberglass applications. Soak brushes and tools in the solvent, then scrub them to remove any resin residue. This will ensure that your tools remain in good condition and ready for future projects. Proper cleaning extends the life of your tools and helps maintain efficiency for your next fiberglass work. -
Question:
Can I add color or pigment to the fiberglass resin?
Answer: Yes, you can add color or pigment to the True Composites Fiberglass Resin to achieve a custom finish. Use compatible dyes or pigments specifically designed for polyester resins, ensuring they do not interfere with the curing process. This allows for creative applications, such as custom art pieces or colored repairs that blend seamlessly with existing materials. Ensure to mix the color thoroughly for an even distribution to achieve the desired aesthetic. -

TRUE COMPOSITES Coatings Editorial Review
The True Composites Fiberglass Resin Polyester Resin is a versatile and effective product, especially well-suited for marine applications such as deck finishing and repairs. Users appreciate its notable adaptability in adjusting curing times by varying the catalyst levels, allowing for both quick and slow work sessions based on project needs. The mixing process is straightforward, and while working in tight spaces can present challenges, the resin remains manageable when mixed properly. Many customers highlight the resin's performance, noting that it works effectively in small batches and bonds well, allowing for satisfactory finishes on fiberglass projects. The visual cue provided by the color change when MEKP hardener is mixed in is also refreshing, helping users ensure full integration. However, feedback regarding quality Consistency arose after True Composites took over Polymer Planet. Some users have experienced inConsistencies in viscosity and gel times across different batches, with reports of an undesirable, fast gelling reaction that can hamper larger layup jobs. Complaints about chunks of resin found in freshly opened containers point to possible issues with manufacturing quality control. Despite this variability, many users remain hopeful, crediting their positive experiences with the product to past iterations and expressing a willingness to continue testing. Overall, the True Composites Fiberglass Resin is generally well-received for its ease of use and flexibility in applications, though potential buyers should be aware of past quality concerns post-transition to True Composites. **
