Why should I apply a sealant?
Sealants are made based on an elastomer and are generally used to create a smooth/flexible joint or transition. They have an excellent sealing effect and are better able (than, for example, cement-based grouts) to absorb some tensions/movements.
Do I use a primer, a coat, or a decoupling mat for sealing?
This choice depends heavily on the situation and the application of your project. Is there a moist environment or are you working within the spray range? This, combined with a risk assessment, determines whether to choose a primer, a paste (coat?), or a complete system of decoupling mats, combined with special fittings.
Isn't a tile finish waterproof?
A finish in (ceramic) tiles should not be considered waterproof, due to factors such as the possibility of microcracks and at the location of the tile edges. Applying the correct waterproofing to the substrate before starting the tiling work is therefore essential.
