Dual Colour

Paarhammer offers a wide range of paints and stains to choose from when selecting the colour of your windows and doors. Using low VOC paints, your window frames are spray-painted by our robot ‘Francesco’ in a state-of-the-art spray-painting area.
Offered as well is the option to have dual colour products. This means the internal timber frame is finished in a different colour to the external frame. This can be done with solid colours or stains.
For instance, common dual colours could be a natural finish on the inside with a solid colour on the outside, or a more dramatic approach of white internal and black external.Certain paints and stains on the outside last longer and increase the durability of the windows and doors through higher pigments in the paint or stain, as the outside is subjected to very strong UV-rays (depending on the direction of the elevation).
But if dual colours are selected, the process of painting increases in its complexity. It increases in time that the windows and doors are in the paint room and labour required to complete these products.
Generally, a single colour window or door frame is sanded, then primed using our spray-painting robot, sanded again and then sprayed with an intermediate coat, left to dry, finely sanded, and finally receives the next or final coat.
Stepped process
Dual colour windows and doors are sanded however, unlike the single colour windows or doors, one side of the product is taped using paper so no colour can transfer to this side. The untaped side is then primed, left to dry, sanded, and sprayed with an intermediate coat. Once dry, it is fine sanded again and sprayed with the final coat.
Care must be taken to ensure the final coat is completely dry before being taped up. This drying process of the final coat can take from overnight to a couple of days. Next, the window or door is flipped over, and the old tape is taken off the unfinished side. The same process as above then occurs on the second side in a different colour.
Unique Feature
Dual colour windows and doors can be a unique feature in homes and buildings. But with this process increasing the time and labour to manufacture, there is an added cost compared to single colour products.
