How to sand a hardwood floor – dustless refinishing

In this video Tim is using a Lagler Hummel to drum sand the floor, equipped with an Oneida Vac cyclone dust pre separator with HEPA filter. The sander and separator are connected to a Blastrac 1219 HEPA vac placed outside the home by a main 2″ and 1.5″ vacuum hose. The combination of this hardware creates an extremely high quality sanding job with hardly any dust whatsoever. After the 8″ hummel belt sander has been used to sand the bulk of the floor, Tim will either use our Clarke Super 7R or Lagler Unico Edger to sand the edges starting with 36 grit up to 120 grit sandpaper. To feather out the edger cut marks into the belt sander area, Tim will use a 6″ Rigid Random Orbit Sander with 80 and 100 grit sandpaper, which also is attached to this same vacuum system. The corners will then be sanded by hand, and then the whole floor sanded again with a Cherry Hill Upright 4-pad random orbit sander with 120 grit sandpaper to eliminate any possible chatter marks left by the hummel. Depending on the degree to which the customer wants the stain to soak in to the wood, Tim may sand the floor a final time with a Clarke square floor buffer with either 120 or 150 grit sandpaper to close the grain of the floor up a little more. The finishing process will be shown under another one of our videos!
