Surface Preparation

About

Surface preparation is the key to the best paint finish. We have collected different fillers for any surface, such as super filler, wood filler from Nordsjo, only the best scrapers, and filling blades from world-leading brands.

Removing intermediate surfaces When considering surface preparation, first think about the materials you want to bond together. Do you want to bond paint to an oxide layer, or do you really want to bond the steel that is under the paint to the aluminium that is under that aluminium oxide layer? Do you want to bond that mold release agent to mold release agent or bond the pieces of polycarbonate under that mold release agent? In summary, use the surface treatment necessary to remove what is covering the material to be bonded. Paint removal Even when it appears easy to just apply adhesive epoxy directly on top of the paint, it is important to bear in mind that the strength of the joint is only going to be as good as the strength of the paint – i.e., if the paint peels off, then the bond will fail. For this reason, it is a very good idea to remove the paint and bond directly to the material underneath. Rust/oxide layer removal Removing rust mainly requires a good rust cleaner with oxalic acid. Try out a few brands and see what you like best. Make sure to use rubber gloves and goggles, as this stuff can be pretty abrasive. Use a wire brush and the cleaner to scrub away the rust. Depending on the extent of the damage caused by the rust and the adhesive you’re using, you may have to sand (or preferably abrade) the area down to a smooth surface before applying the adhesive. It’s a good idea after all this sanding and brushing to give your metal surface a good clean off with a clean cloth and some acetone or isopropanol. These act as a good degreaser and evaporate to leave a clean, dry, contamination-free surface to bond to. Many metals fo
