    Default Quick question re sanding

    Hi All,

    I have a quick question re sanding please.

    I am currently working with some pieces that are 330 x 19 x approx 900mm. I am sanding them back and will ultimately finish them with hard burnishing oil. In the finished product only one side of each piece will be visible.

    How far should I sand back the non-visible side?

    Someone told me once that you should finish both sides of a piece exactly the same, in order to stop it warping or bending with time. That seems OK to me, but to sand back a piece of wood to 1500 grit (for example) and burnish it, knowing it will never be seen again, seems overkill to say the least. Where is the line? In past projects I have sanded back to 300 grit and put on some sanding sealer before then concentrating only on the good side, but even that is potentially a lot of work. On my current project I am dealing with 12 of these babies! If anyone thinks I shouldn't be bothering at all with the back side I would be very glad to hear it!

    Any thoughts?

    Andrew

    Hi Andrew,

    I would usually finish the underside of a piece to 400 grit, then just give it two coats of oil, no further sanding. Seems to work OK for me. I don't see any point in burnishing the underside of a piece that will only show one face.

    Regards,

    Rob

    As long as the non-seen face is sealed it doesn't matter if you stop at 80 grit.

    I would stop at 80 grit but make sure it is well sealed as well

    The sealing is the important part not the sanding for the non seen side,movement should be stabilized if both sides are treated the same. We are talking about the movement that will occur if only one side is sealed not seasonal movement.

    Thankyou all for the feedback and advice.

    Is it safe to assume a coat or two of simple sanding sealer would be adequate to seal the non-visible side? Or do I need something more robust?

    I always thought sanding sealer was just really fine grain filler
    I'd be using the same product all over and just not worry about how the back looks.

    When someone looks at the underside of one of my pieces in a hundred years, they will note that it is sanded and finished to the same standard as the top.

    Only 'cos they are likely to be confused & look at it upside down.
