Can You Sand Plywood Edges

- Aug 06, 2020-

If this is the case, you can sand the edges to chip off the increased grain, which can cause a lot of damage to the surface of the film. 


If the plywood edges are pitted, a wood filler will help, but with plastic putty or a knife. Once the wood fillers have dried, a light sanding should be enough to get them smooth, and done. 

Remember that the wood fillers you use shrink when they dry and shrink over time, as with any wood fillers you use. 


In this case, you should sand each layer with 120-grit sandpaper before applying the second layer to a smooth, even surface. Be sure not only to sand the ends of the board but also to fill them, as the boards are often rough and most plywood boards have cavities. 


This also allows you to fill in the final grain to create a smoother surface for painting. Dry construction sludge is particularly suitable as a surface filler if you use C or D construction plywood and want a smooth surface. Skim the entire surface with a wide drywall blade (10 - 12 '' ') before trying to finish the drywall work. 


Let the sludge dry completely and then sand it with 120-grain sandpaper with a 1 / 2 '' wide drywall knife (10 - 12 '' '). 


If this is the case, grind the edges with a 1 / 2 'wide drywall knife and cut off the increased grain. If you need a coat, especially in bad areas, apply it and let it dry before sanding it again. 


Once the wood filler has dried, a light sanding should be sufficient to obtain a smooth plywood edge. If you have trimmed or pitted the edges of the plywood cutting saw edges cut with plastic putty or knives - wood fillers will help and smooth them. 


One trick I sometimes hear about is wetting the wood before the next and last sanding. Remember that all the wood fillers you use shrink when they dry, so shrink them and grind them as best you can. 


If you use a water-based stain, you can grind and bury the increased grain caused by it, but if you use it, you will grind it through. This solves the problem because the wood takes hours to dry enough to seriously slow down production and the last gravel is sanded so hard that the point of using this gravel is to remove the scratch from the previous gravel. A better solution, at least for water-based surfaces, is to sand the first layer as it dries, taking care not to sand to the end, even if it is just a little. 


You examine your workpiece and decide what you think is necessary and whether you can find it within reach. If the color you used has a lot of shine, the surface may need to polish up a little color, so hit it again. 


Most plywood parts have a front frame that covers the edges, so operating the board with a planer or blunt knife requires coarse grit that you veneer. 


If the surface can be processed with 180 grits, for example, a coarse grit size of about 1 / 4 to 1.5 grits can be used. You should not start with a too coarse grit, as scratches can be made on the edges of the plywood, which can damage the board. It would be a total waste of time and energy if you started to do this and you would run the risk of scratching. 


The appearance and feel of the surface are taken alone and have nothing to do with how finely the wood is sanded, if at all. Every oil-lacquer mixture has a measurable structure due to the roughness of the wood, which is caused by a coarse grinding, which telegraphs through and through. The surface can ultimately be made smoother by sanding it with a hardening layer or by sanding an additional layer while it is still wet on the surface with grain sanding paper of 400 to 600 grains. 


It is better to sand the wood in a back and forth movement, but if you sand the wood with grains of 400 to 600, it is much easier than 400 or 600. 


For an even smoother surface, sandpaper with a higher grain can also be used, which is not required for plywood. After applying abrasives, a dust-free, clean surface is required, and in some cases, even more important. 


The open edges of the plywood make for a really fun style, but if you want a refined look, there are three main ways to enhance your plywood edges. Plywood is flaky around the cut edges, so the sanding process ensures a clean, finished edge.
