Generally speaking, we do not recommend using silicone sealant on wet surfaces. Because silicone requires a dry, clean surface to bond and cure properly. If you apply it to a wet surface, moisture may affect its adhesion to the substrate, preventing the formation of an effective seal.However, some special types (such as products marked as "marine grade" or "suitable for wet environments") can be applied in wet or foamy conditions.If you need to repair buildings such as bathrooms and boats that have been water-damaged, please be sure to check the product label to confirm whether it can be used in such environments. Otherwise, it is best to thoroughly dry the area to be treated before using the standard silicone sealant.

It is generally believed that silicone sealants are insulators, meaning they do not conduct electricity. This characteristic makes them very suitable for sealing electronic connections and components, preventing moisture ingress, providing corrosion protection, and avoiding current flow. However, the following points need to be noted: Type: Not all silicone sealants are the same. Some may contain additives that affect their conductive properties. If you need to apply silicone sealant in situations where supply and demand conflict, please be sure to rely on the manufacturer's specification sheet

Considering these factors, silicone-based products should be chosen carefully in order to achieve optimal results: -Choose a specific type designed for wood or outdoor use. These include additives which promote better adhesion and longevity.-Surface preparation is important before application - it needs to be free from grease, dust or moisture.-With its flexibility trait, silicone masked joints on Wood may move along expansion & contraction due temperature changesIf appearance matters search for shade close toning with timber finish
