What is the universal BILKA sealant intended for?

The universal BILKA is a silicone roof sealant recommended by the manufacturer for metal tiles and the gutter system. It is used only in details where the system instructions allow mastic or silicone. The term "universal" does not mean automatic compatibility with every plastic, membrane, paint, or bituminous material. Before application, the substrates and conditions must be checked in the technical sheet for the specific package with SKU LT-5056.

Is the universal BILKA silicone also suitable for gutters?

Yes, the general product page of BILKA explicitly states use for the gutter system as well. This does not mean every joint is filled with silicone: gutters, connectors, and their covers have a specific factory assembly method. Sealant is added only where the installation instructions require it. In case of leakage, first check dimensional compatibility, sealing, expansion joint, and proper clamping of the elements.

How does the universal BILKA sealant differ from Premium?

The universal product is described as a silicone roof sealant, while Premium is a hybrid polymer with zinc. This is the confirmed difference in the official overview. No comparative values for joint movement, adhesion, UV resistance, or curing have been published, so it cannot be stated which is more suitable without a specific detail. The choice is made based on substrate requirements and the current technical sheets of both SKUs.

What is the product code of the universal BILKA silicone?

At LATIVA, the universal sealant is a single Shopify variant with SKU LT-5056 and barcode LATZIMI1G. There is no selector for color, volume, or packaging type. Therefore, these characteristics must be confirmed by the actual label before ordering, especially if the joint will remain visible. The code differs from Premium LT-5057 and should not be substituted just because both products are shown in the same category.

Can the universal BILKA silicone be used for structural or highly movable joints?

It cannot be recommended for structural or highly movable joints based solely on the product name. The official data used do not specify movement class, modulus, allowable width, or standards for such use. For a critical node, a technical sheet and design requirement are needed. The universal roof sealant may participate in permitted system joints but does not replace a specialized facade or structural product without written confirmed compatibility.

How to prepare the substrate for universal BILKA silicone?

Preparation must follow the label and technical sheet for the specific batch, as Shopify and the overview page do not provide detailed rules for cleaning, primer, and temperature. It is not applied on unstable, contaminated, or unknown substrates expecting the product to compensate for the defect. Before sealing, check the joint geometry, water path, and mechanical fastening. In the absence of manufacturer instructions, LATIVA must confirm the application.
