Tintas Douro has several enamels for embellishing and protecting different surfaces with three types of finishes: Gloss, Semi-Gloss and Matte.
To choose the type of enamel we're going to use we should consider the substrate's characteristics (walls, metal or wood and if it is going to be applied indoors or outdoors).
In any case, it is extremely important to prepare the substrate in order to achieve the desired results, namely through the application of a primer that suits its characteristics.
