Greaseless Compound Preparation
Greaseless compound
is a glue/grit mix it is ideal removing deep marks, scratches and to
provide a satin finish on a work piece. It is commonly used prior to
finishing with mops and compounds. The greaseless method will allow
you to take metals which are in a very poor condition and through
several processes you will be left with a semi-bright surface ready
to be finished with mops & compounds. Greaseless compound can be
applied to any type of mop (except sisal) and to felt bobs of any
shape and size. When using greaseless compound you do should run at
speed of around 1200-1500 rpm.
Grades Available
There are several grades of greaseless compound available. The lower
the grit number, the coarser the abrasive (faster metal removal but
poorer finish), higher the grit number, the finer the abrasive (slow
metal removal but better finish). To take a metal from a poor
condition to a condition so it is ready to be polished, will take
several greaseless compound processes; for example you can start at
a wheel coated with 80 grit greaseless, your next process would be
with a mop coated with 240 grit greaseless and after that the wheel
coated with 300 grit greaseless.
80 grit Coarse grade for removing deep marks and scratches.
150 grit Medium grade for removal of marks & scratches.
300 grit Fine grade, you can move onto polishing after this grade
Mop Preparation
Before you can use greaseless compound you must first prepare a
mop/felt. If you are using a drill we recommend it be mounted on a
vice, it will make coating the mops much easier.
a. Attach mop to adaptor and make sure it is screwed on tightly.
b. Peel back the plastic wrapper from the greaseless compound.
c. Apply the exposed compound to the running mop. (the heat
generated from the running mop melts the glue/grit onto it, the coat
will thin and sticky.
d. Leave mop running for a few minutes, this will help the coat to
dry quicker.
e. Repeat c & d until a thick coat is on the mop.
f. Remove the mop and allow to dry. Drying will take a couple of
hours.
g. The mop will now be ready to use.
h. When using a selection of wheels with same or different grits it
is often wise to prepare all your wheels in advance.
It is also good
practice to mark your wheels with the abrasive grade, as there is
very little difference visually between the different grits.
