An overview of the features: Products: In just a few steps, the user will find the right product for use in the areas of "sealing", "bonding" and "priming". On the respective product page, you will find all the essential details from data sheets and test materials to processing videos. Consumption calculator: The consumption calculator makes it very easy to determine the required amount of sealant based on joint dimension. The quality of the primer can be calculated in the same way. Colour recommendation: For a uniform appearance, the colour of the silicone sealant must always match the grout being used. The app now makes it possible to select your hard joint mortar (tile adhesive) in order to get a suitable colour recommendation for the OTTO sealant.
