Question:
What is Dicor 501LSW-1 Self-Leveling Lap Sealant used for?
Answer: Dicor 501LSW-1 Self-Leveling Lap Sealant is primarily designed for sealing roof seams and lap joints on various types of RVs, trailers, and mobile homes. Its self-leveling properties ensure a smooth, even application, making it ideal for horizontal surfaces where water pooling may occur. This sealant effectively prevents leaks, prolongs the lifespan of your roof, and is resistant to UV rays, weathering, and extreme temperatures. -
Question:
How long does Dicor 501LSW-1 take to dry?
Answer: Dicor 501LSW-1 typically takes about 24 hours to cure fully under optimal conditions, which is at temperatures above 60°F (15°C) and low humidity. However, the initial skinning time is faster, often within 1-2 hours. For best results, it’s essential to allow the sealant to cure completely to ensure maximum adhesion and seal effectiveness. This is particularly important for RVs exposed to the elements, where a reliable seal is crucial to prevent water damage. -
Question:
Can Dicor self-leveling lap sealant be painted over?
Answer: Yes, Dicor 501LSW-1 can be painted over once it has dried. It’s recommended to use a compatible paint that adheres well to silicone-based sealants. This is useful for maintaining the aesthetic appeal of your RV or trailer. Before painting, ensure the sealant is fully cured and clean the surface to improve paint adhesion. This allows you to customize the appearance while maintaining a durable, waterproof seal that protects your vehicle. -
Question:
Is Dicor Self-Leveling Lap Sealant suitable for use on all roof materials?
Answer: Dicor 501LSW-1 is versatile and compatible with most roof materials, including fiberglass, metal, wood, and rubber. However, it is essential to ensure the surface is properly cleaned before application to achieve optimal results. This ensures a strong bond between the sealant and the roof, preventing potential leaks. Its compatibility with various materials makes it a popular choice among RV and trailer owners for effective maintenance. -
Question:
How do I apply Dicor Self-Leveling Lap Sealant?
Answer: To apply Dicor 501LSW-1, start by cleaning the area thoroughly to remove any dirt, debris, and existing sealant. Use a caulking gun for easy application, and apply the sealant in a continuous bead along seams, joints, and any cracks. Its self-leveling properties will help spread the sealant evenly. Allow it to cure as per the manufacturer’s guidelines for the best protection against leaks and weather elements. -
Question:
Is Dicor 501LSW-1 UV resistant?
Answer: Yes, Dicor 501LSW-1 is formulated to be UV resistant, ensuring that it won't degrade or lose effectiveness when exposed to sunlight. This characteristic is vital for outdoor applications, especially for RVs and trailers that are constantly subjected to varying weather conditions. Choosing a sealant with UV resistance prolongs the life of your seal, providing peace of mind for long-distance travels and outdoor adventures. -
Question:
How many tubes are included in a 4-pack of Dicor 501LSW-1?
Answer: A 4-pack of Dicor 501LSW-1 includes four tubes of 10.3 oz each. This quantity is typically sufficient for multiple repairs or applications, making it an economical choice for RV enthusiasts or contractors working on various projects. The 4-pack allows for ample supply, ensuring that you always have extra sealant on hand when routine maintenance or unexpected repairs are necessary. -
Question:
Can Dicor self-leveling sealant be used on vertical surfaces?
Answer: Dicor 501LSW-1 is specifically designed for horizontal applications due to its self-leveling feature. For vertical surfaces, it's recommended to use Dicor's Non-Sag Sealant to ensure proper adhesion without running or sagging. Understanding the application types for each sealant will help you address your needs effectively, ensuring that your vehicle is properly maintained. -
Question:
What temperature should I apply Dicor self-leveling sealant?
Answer: For optimal application, Dicor 501LSW-1 should be used when temperatures are between 60°F (15°C) and 100°F (38°C). Applying it outside this temperature range may affect its curing process and overall performance. To achieve the best seal possible, ensure warm, dry conditions, and avoid applying in rainy or excessively humid conditions which can lead to moisture-related issues with adhesion. -

Dicor Sealants Editorial Review
This self-leveling lap sealant from Dicor is a popular choice for RV roofs. Customers have used it successfully on aluminum roofs, but it may not be suitable for certain types of TPO roofs. It takes around 30 to 40 days to fully cure. The sealant is not recommended for vertical surfaces, but Dicor makes a non-self-leveling sealant that would work. Customers recommend cleaning the area before applying the sealant and carefully monitoring for separation and cracking. The sealant performs as described, and customers recommend it for resealing roof components like vents. Some customers have reported delivery issues with the US postal service. The product comes in white, and customers have seen it offered in different package sizes. Overall, this is a cost-effective solution to resealing an RV roof.
