When sanding plywood, it is important to treat the surface like a veneered layer and to avoid the sander from falling on you. In this case, I tried to paint the edges and sand and fill them with a color that blends with the face of the veneer. You can sand through the surfaces, but in any case, you should finish the sanding work by passing through each grain with 120 - 150 grains of sandpaper. Use your machine to smooth the grains, then adjust the machine and brush the edge with your hand.
This is also a good way to remove the swirl marks left by the orbital sander, which may only occur when the finish is applied. I have improved from 180 to 220 grains, for example, but if you apply a stain, the best policy would be to sand with a squiggle.
When sanding on a flat surface, use flat blocks to secure the sandpaper and advance to the next finer grain. If you are sanding for a little longer, you can use one or finer grains, but it is most efficient to use the same grain sanding paper that you used for your last machine sanding machines. If you use one of the three sanding methods, you can remove the sanding dust with a fine sander, as shown in the photo above.
Grinding each grain often removes the stock faster than sanding through the grains, but it does more damage to the wood than sanding.
It is tempting to take a piece of sandpaper and sand it off without using a supporting block, but if you get into a situation where you cannot avoid sanding through the grains, such as in a joint where two parts meet at a right angle, you should try to use the back of a wooden block with some wood glue on it. If the sandpaper is not perfectly flat on the wood surface, an uneven surface may develop.
It is better to sand in a back and forth motion than with a single piece of sandpaper at the same time, as with a block of wood with wood glue spreader.
High grain sandpaper can also be used for an even better smooth surface but is not required for plywood. After applying sanding seals, dust-free and clean areas are required, such as on the wooden edges or on a piece of wood with glue.
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 the plywood edges. Plywood is flaky around the cut edges, so the sanding process ensures a clean, finished edge. Sanding sealant can be applied to the plywood with a leveled brush stroke to coat the surface. I ground it with Blaine to make something creative for an upcoming project, and it helped to ensure clean and finished edges!
The solid wood edge not only gives a beautiful, finished look but also allows you to cut and shape the edges to obtain a high-quality, tailored look.
If you still paint the piece, you can fill the cavities at the edges with a spatula, such as grout. Remember that the wood filler you use will shrink when it dries, so consider this method over.
Also, be sure to sand and fill the ends of the board, as most plywood boards have cavities and boards often behave rough. In this case, you should sand each layer with 120-grit sandpaper before applying the second layer on a smooth, even surface.
Dry construction sludge is particularly suitable as a surface filler if you use C or D construction plywood and want a smooth surface. This also allows you to fill in the final grain to create a smoother surface for painting. Skim the entire surface with a wide drywall knife (10 - 12 '' ') before trying to finish the drywall.
Sanding the sludge with 120 grit sandpaper and let it dry completely before sanding again. If you need a layer, especially in the worst areas, apply a thin layer of 1 / 4 ''. (1,5 '' ') sludge, sanded again, and another layer of dry construction sludge (2 - 3' '').
Trying to glue paint tape to the plywood to protect it from sanding, but not too much tape, just enough to cover it.
If you have a router, you can use a flush trimming tool to balance the two surfaces, but of course, try your best to align the edges flush. Slowly move the router and hold the router firmly to the edge of the workpiece with two hands.
A sanding belt with grain 150 - 180 must be used, and a very good belt sander is a good choice for flush edging of the plywood floor. Sanding the edges flush and slowly so that you do not sand the veneer but do not coat it - sand.
