Non Sanding
Non-sanding or wet-on-wet coating refers to a method of painting where additional coats are applied before the previous coats have cured. The composite coated film then cures or dries as a whole. In this technique, specially formulated paints are required.
The advantages of non sanding / wet-on-wet
The main advantage of this method is the considerable time saving, as it avoids the waiting time between coats and the subsequent sanding normally required to achieve a smooth and even finish. This makes the wet-on-wet technique ideal for applications where efficiency and speed are of the essence.
Preparation of the surface
Although the non-sanding technique reduces the need for sanding between coats, it is still important to ensure that the surface is clean, dry and free of impurities such as dust, grease, oil or old paint residues. This ensures optimal adhesion and a uniform finish.
Choosing the right paint
Choose a paint specially formulated for wet-on-wet applications. These paints typically have a faster drying time and are designed to be compatible with multiple coats. Carefully read and follow the manufacturer's recommendations and instructions on application and drying time.
Work environment
Ensure that the work area is well ventilated and has an appropriate temperature and humidity in accordance with the manufacturer's recommendations. This contributes to the correct drying and curing of the paint and reduces the risk of unwanted problems such as bubbles or cracking.
Application technique
Use an even and controlled application technique to avoid overspray, drips or runs. It may be a good idea to practice on a smaller surface or make test applications before starting the actual project.
Drying time and curing
Although the non sanding technique reduces drying time between coats, it is still important to allow each coat to dry and cure completely before applying the next coat. Avoid applying too thick layers as this can prolong drying time and increase the risk of uneven curing.
Requirements for non sanding paint
However, to achieve the best results with the wet-on-wet technique, specially developed paints that are formulated to work with this application technique are required. You will see in the technical data sheet whether primer and filler can be used as non-sanding. On this page, we have collected our bottom products that you can use as non-sanding.
