Grinding Hardwood Floors
The Rhino will flatten and smooth out old chatter marks or divots from previous systems and provide a beautifully smooth finish in a short time with minimal edging. The ability to breakdown the machine into 3 easily manageable and portable pieces allows mobility and access into the most difficult job sites without the use of ramps or elevators.
The high torque of this geared down machine will mow through virtually any type of wood in the worst of conditions. Nothing stops a Rhino!
Step 1 To remove old coatings, overwood, etc, use 30/40 sharktooth metal bond diamonds without weights. Speed should be between 600-800 RPM. (The machine should be kept in constant motion to avoid burn marks.)
Cross-hatch floor until 80-90% removal is achieved.
Step 2 Install 40 Grit sandpaper onto velcro adaptor plates and attach to machine. Proceed to sand at low speed without weights. Depending on type of wood and desired cutting depth, speed and weight may be increased if necessary. (Note – operator experience and rate of forward motion will effect the use of speed and weight. It is better to start at a slower speed without weights until you gain more experience and then increase until you find the optimal combination for they type of hardwood and they conditions you are working on.)
Step 3 – Install 80 Grit sandpaper on to the machine following same guidelines as above.
Step 4 – Clean floor thoroughly, apply sealer and allow to dry. (If using water sealer screen lightly to remove grain raise.)
Step 5 – Apply first coat of finish and allow to dry.
Step 6 – Screen lightly using 120 Grit screens at low speed with no weight. Vacuum floor thoroughly and tack to remove residual dust from screening process.
Step 7 – Apply final coat and allow to cure.
Hardwood Stained Floor Systems
1. After 80 Grit sandpaper step has been complete (see above step) screen at low speed without weights using 100 Grit screens and random orbital sander.
2. Clean floor thoroughly and apply stain and allow to dry. Apply sealer and allow to dry.
3. Apply sealer and allow to dry
4. Apply first coat allow to dry.
5. Screen if needed and then apply final coat.
