Most cleaning and polishing activities require compounds and buffing pads and at least two operations:
cutting and coloring.

Cutting means cleaning with sharp cutting compounds to remove additional surface imperfections and
give a moderate luster.

Coloring means final cleaning that is done with finer compounds to bring out the natural color and luster
of the material.

MIBRO offers a broad variety of compounds and buffing pads suitable for every task.

Compounds

Compound is the material applied to the surface of a buff. In consists of abrasives that are held in a wax or
grease suspension.
MIBRO’s numbering system and color-coding packaging clearly identifies each compound and its application.

Compound #1 provides coarse buffing and delivers a very fast cutting action approaching that of flexible grinding.
USES: Used to remove scratches, rust and burs on steel, stainless steel, iron and other hard metals.

Compound #2 offers a very fast cutting action and good coloring action.
USES: Used for regular cleaning on steel, stainless steel, iron and other hard metals.

Compound #3 provides a mild cutting action and good coloring action.
USES: Used for regular cleaning of soft metals such us aluminum, pewter, copper, brass and brass plate.

Compound #4 is the perfect solution for final coloring of precious metals and jewelry.
USES: Used for regular cleaning of gold, silver and platinum.

Compound #5 produces a high gloss finish and removes scratches.
USES: Used for light polishing of brass, aluminum, plastic, iron and steel.

Compound #6 has a precious composition for the finest finish on precious metals.
USES: Used for high gloss polishing on gold, silver and platinum.

Refer to the table below for the recommended compounds:

Material\Type of cleaning	Heavy duty cleaning	Regular cleaning	Light polishing	High gloss polishing
Hard Metals	1	2	5	6
Soft Metals	-	3	5	6
Precious Metals	-	4	5	6

Buffing Pads

Buffing pads consist of one or more single buffs. They should always be mounted on a spindle between flanges
that firmly grip the sides.

Choosing the right type of buffing pad

There are two types of pads for different operations:

Cushion or “medium” type buffs are used for light cutting or coloring, the buff is held together with two circles of
lockstitch sewing. Provides a resilient cushioned effect when in use.

Spiral sewed or “firm” buffs are used for coarse buffing or cutting, this buff has continuous spiral sewing with
¼” spacing. The spiral stitches give a much firmer buff and more pressure can be exerted.

Choosing the right size buffing pad

The thickness of the buff face is determined by the size of the bench grinder or drill motor. For most efficient operation
use the largest diameter and thickest face possible. Please refer to the table bellow for choosing the right buffing pad.

Motor Size vs Maximum Thickness of Buffing Face

Motor Size	4” Diameter Pad	6” Diameter Pad
1/8 to 1/6 H.P	1"	1/2"
¼ H.P.	1	1/2"
1/3 H.P.	2 1/2"	2"
½ H.P.	2 1/2"	2"

Applying Compounds To A Buffing Pad

• Make sure the buffing pad is revolving towards you.
• Pass the compound lightly across the buffing pad face, in front and a little below the spindle.
• Apply the compound in ½ to 1 second applications until the buffing pad face is lightly coated.
• Hold a clean piece of scrap metal across the face to spread the compound uniformly.
• Repeat the above steps as necessary until the buffing pad face is uniformly coated.
• To apply more compound use a wiping motion-being careful not to overload the wheel.
• Never use a buffing pad for polishing that has been used previously for cleaning. We strongly recommend that
  separate buffing pads be used with each compound.
• Never put compound on the item to be cleaned/polished.
