Substantial stair elements this sort of as treads and risers are very best tackled with a sanding machine (don’t forget to wear a dust mask and security eyeglasses). There are numerous styles which include:
Belt sanding machine – perfect for big, flat expanses these as staircase treads
Random orbital sanding device – can be utilized on a wide range of flat and a little bit curved surfaces
Detail sanding machine – ideal for mild sanding in tiny areas and corners
Sheet orbital sanding equipment – good for gentle-responsibility responsibilities and corners
Belt sanding device
This impressive device works by implies of a sandpaper belt that turns on rollers at each end of the device. It is excellent for major-responsibility tasks involving significant, flat surfaces that have to have velocity fairly than finesse. This will make it fantastic for sanding down stair treads and risers. Inexperienced persons beware, nonetheless – you can conveniently spoil the surface if you are not watchful.

Sand parallel with the wooden grain and retain the equipment going all the time for an even final result. Only mild strain is expected, so enable the body weight of the tool do the function.
Random orbital sanding equipment
Preferred with carpenters, joiners and Do-it-yourself buyers alike, this form is the most versatile, and is a lot easier to use than a belt sanding device.
The device works working with a round abrasive disc which vibrates whilst rotating at pace. It moves in an elliptical (irregular) orbit, which makes sure that no section of the disc travels along the exact same route two times. This pretty much gets rid of the prospect of leaving swirl marks. You can use it for both of those coarse and wonderful ending operate by attaching diverse grades of disc.

Do not hope miracles. This machine is not supposed for major-responsibility do the job, so you will will need to go thoroughly. Shift the resource little by little and evenly above the surface for a regular end, and keep away from pressing much too really hard.
When you appear to the spindles, a machine will be of minimal use. As an alternative, wrap strips of sandpaper close to the shafts and pull them back again and forth. You may have to resort to making use of a chemical paint stripper on intricately formed stair sections.
Sanding is tricky function! If you want to get rid of each individual last trace of the old coating from your spindles – in buy to utilize wood stain or clear varnish, for example – consider replacing them with new spindles in its place.
