Does Plywood Need Sanding

- Aug 13, 2020-

I examined my workpiece and decided that I thought it needed a little color tweaking because the color I used had a lot of shine. I came back into this area and, finding it within reach, I decided to investigate it and think about what I needed it for. 


Most of the pieces I build with plywood have a face frame that covers the edges, and I sanded one side smooth to varnish and enhance it. Most of the interior projects I have built have been made with pine veneer and are usually labeled with something like "polished pine" or "BC sandeply." They are relatively inexpensive ($20 or less) and have sanding on one or both sides for smooth lacquering or finishing, but not on the other side. 


OSB is sometimes referred to as a "wafer board" and consists of wood chips glued together in a curious patchwork design. Remember that the wood filler you use shrinks with the weight of the board. 


In this case, you should sand each layer with 120-grit sandpaper before applying the second layer on 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 cuttings saw boards have cavities. 


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


Rub off the sludge with 120 grit sandpaper and let it dry completely, then sanding again with a sander. If you need a coat of paint, especially in bad areas, apply a thin layer of sanding mud (about 1 / 4 'thick), let it dry, and then sanding and applying again. 


It is not uncommon for faults in the wood (missing holes in the putty) to occur after the primer has dried, but you could not see it before. If you encounter a problem, simply correct your primer, resand the affected area, add more putter and sand again. This will help to make your project run smoother, and also help with problems with the paint. 


Make sure that the wood fibers do not completely adhere to the surface of the plywood and that they do not damage your wood. 


The right care allows your wood to have a uniform color if desired. Dyeing plywood does not require any special yellow stains, although with the preconditioning of the wood you can use pretty much any other wood stain. As with any other wood, however, it is important to ensure that the surface looks as desired and sticks to the laminated wood with the appropriate equipment. 


We recommend sandpaper with 80 grits for this work, although a dust cloth at hand facilitates the removal of dust and dirt by sanding. We recommend starting with the 80 grit sandpaper to obtain a base before moving on to finer grits, as they will be smoother and more vibrant on the wood. After you have cleared the sandy mess, you can proceed to step 2 of the process. 


Even the simplest plywood panels can look like lacquered surfaces, so you want to make sure you get as much of it as possible, especially in the elevated areas of the wood. When sealing or even varnishing your laminated wood, apply one layer of laminated wood one side at a time. 


It takes a lot of sanding to get the desired shine, but you don't have to do much. If your plywood is relatively new and smooth, you can probably sand both sides and edges. I use a sanding block with a 2.5mm sanding head to sanding the sides and edges, and I have done it on a variety of different types of wood, from old - school wood to relatively new, smooth - bead wood. 


Wipe the wood clean with a cloth, and then it is time to try out the iron veneer on the top and bottom of the plywood, and on the sides and edges of both sides. 


Applying the sealer is not difficult, but the moisture from it increases the grain of the wood so that it feels rough again. A good way to test it is to apply it to an additional piece of plywood and then apply the stain to see what the finished result will look like. You need to add more spots to the plate, such as red, white, blue, yellow, green, orange, or yellow. 


Even if it may seem laborious, the finished product looks a lot better after done footwork when filling and sanding. The birch has a nice smooth grain and is very easy to sand, which makes it perfect for all types of finishing projects, including cabinets.
