Application Instructions

Step by step instructions

To attain optimum performance, it is essential that the target surface is completely clean; it must be free from all soling of any type, including waxes, silicone coatings, etc., otherwise the coating will not be able to bond to the surface. Before full application, please always carry out a test on an inconspicuous location.

This technology is a „professional“ product.

Please ensure that the application is performed outdoors or in a well-ventilated and dust-free area. Please note that the liquid contains strong solvents which should not be inhaled. The wearing of protective gloves and eye protection is also recommended.
The surface to be coated should not be too hot; so do not coat the barbecue if it was located directly under the sun prior to application, otherwise the liquid will “flash off” too rapidly and the coverage will be reduced. Ideally the process should be conducted at an ambient temperature 15-20°C ( +/- 5°C).
Plan your work carefully. Ideally coat all of the surfaces in a successive process as this will ensure maximum coverage.

1. Pre-Cleaning with Biosativa

First, meticulously pre-clean the barbecue. Next, rinse the surfaces thoroughly with water in order to remove any residues. Dry with a cloth or kitchen wipes. The better you perform the pre-cleaning, the better the adhesion and subsequent longevity of the coating. After completion of the general cleaning process, deep clean the surface with alcohol (e.g. IPA). Some minutes after cleaning with the alcohol wipes once again wipe the surface with a clean dry cloth.

2. Application of the coating

Use the thin and smooth micro-fiber cloths provided within the kit to apply the coating. Completely moisten the cloth with BBQ & Pizza Oven Liquid Glass Coating. Apply the coating swiftly and evenly by wiping. When applying to surfaces such as grill bars and meshes simply wipe on and leave the surface to dry. On surfaces such as the doors or dome of the BBQ , wipe the coating on to the surface (ensuring full coverage) and then buff the surface with a lint free cloth or micro-fiber.

3. Buffing/Polishing the coating

Buff the coated surface 1-2 minutes after the panel/surface has been coated. Do not wait longer than 2 minutes before this buffing action. You must ensure not to aggressively remove too much of the coating. Do not use excessive pressure. Use a medium to smooth micro-fiber cloth. In warm conditions the coating becomes dust dry after 2 hours and touch dry after 5 hours.
The coated item takes many days to fully cure even. Ideally allow 5-7 days. Between coating and usage. Placing the BBQ unit in a hot environment / in direct sunlight is ideal as this will enhance the speed of curing. The coating will withstand temperatures of 600°C.
