Can I Put Dicor Over Top of Silicone Sealant?
When it comes to RV maintenance, ensuring a strong and watertight seal is crucial. Many RV owners rely on silicone sealant for various applications, such as sealing roof seams, windows, and other exterior elements. However, there may come a time when you need to apply a protective layer or additional sealing material over the silicone sealant. In such cases, Dicor is often considered a suitable option. But can you really put Dicor over top of silicone sealant? Let's explore this topic in more detail.
Understanding Dicor and Silicone Sealant
Dicor is a product used specifically in the RV industry for roof repair and sealing purposes. It is a self-leveling sealant that provides excellent adhesion to a variety of surfaces and creates a long-lasting watertight seal. Silicone sealant, on the other hand, is a versatile sealant commonly used for its ability to withstand extreme temperatures and resist UV degradation.
1. The Compatibility Factor
One of the key concerns when adding a new layer of sealant over an existing one is compatibility. Fortunately, Dicor is typically compatible with most silicone sealants. This means that you can generally apply Dicor over top of silicone sealant without any issues. However, it is still recommended to test a small inconspicuous area before proceeding with a full application.
2. Preparing the Surface
Before applying Dicor over silicone sealant, it is crucial to properly prepare the surface. Start by cleaning the area thoroughly, removing any dust, dirt, or residue. If there are loose or peeling sections of silicone sealant, they should be carefully removed. This can be done using a utility knife or a suitable tool without causing damage to the underlying surface.
3. Applying Dicor Over Silicone Sealant
Once the surface is clean and prepared, it is time to apply the Dicor sealant. Ensure that the silicone sealant is completely dry before proceeding to apply Dicor over it. Use a caulking gun to apply an even bead of Dicor directly over the silicone sealant. It is important to maintain a consistent thickness and ensure good coverage.
4. Smoothing out the Sealant
After applying the Dicor sealant, use a putty knife or a plastic smoothing tool to create a smooth and neat finish. Dicor is a self-leveling sealant, so it will naturally spread and level itself. However, using a smoothing tool can help achieve a more professional appearance and ensure proper coverage.
5. Curing and Drying Time
Dicor sealant usually takes about 24 hours to cure and dry completely. While the initial drying may occur within a few hours, it is advisable to avoid any contact or exposure to water during the curing process. This will ensure the best results and long-lasting performance.
In conclusion, when it comes to adding an additional layer of sealant over silicone sealant, Dicor is generally a suitable option. Its compatibility with most silicone sealants makes it a convenient choice for maintenance and repairs. However, proper surface preparation, application techniques, and curing time should be followed to ensure a strong and durable seal. By following these guidelines, you can confidently apply Dicor over top of silicone sealant on your RV, ensuring that it remains protected and watertight for years to come..
