The most common types of defects of plywood are nothing more than: cracks, corners, drum, plate surface area and defects, etc. If the defective plywood area is not very large, we can use some small methods to repair it.
If there are cracks, falling off the holes, we can judge the repair method according to the size of the plywood cracks. The narrow gap is filled with putty, and the wide seam can be filled by Ouyong wood strip, and treated with adhesive bonding. If it is a small hole directly filled with putty, big words to dig, that is, with the end surface milling cutter milling the defective parts, cut the same color of single plate patch, glue filling, press the patch to make it firmly, will dig the patch parts clean.
If the plywood has a glue problem, use resin glue or the same glue as the plywood, fill with a path, pressure to make the glue stick, and clean up the repair parts.
If it is a bubble problem, you can bend the part of the bubble or the glued veneer, carefully cut a hole with a knife, fill a small amount of resin glue with cold or hot pressure stick.
If the local plate can not only be manual or electric planing or sandpaper grinding. Using putty to repair defects is a better method, because it is relatively easy to make putty, low price, simple operation, less labor.
