Polishing pads
Choose a pad as part of a system: machine, compound, paint condition and pad care.
What is a polishing pad?
A polishing pad is a consumable attached to a polisher's backing plate that makes contact with the surface. The pad, compound, machine movement and paint condition work together to determine the amount of correction and the finish.
Changing a pad's construction or condition can change the result even with the same compound. A different result does not, by itself, prove that the pad is the only cause. Treat the material, product, machine and working conditions as one system.
Start with the product's intended use and machine compatibility. Test a small area and adjust the combination only as needed.
Material does not define a universal cutting grade
- Foam: check construction, firmness and the product's cutting or finishing role. Foam does not always mean a mild pad.
- Wool: check fibre structure, length, backing and recommended machine movement. Wool is not always the most aggressive option and does not automatically require a foam finishing step.
- Microfibre: check fibre and backing construction and the stated grade. Microfibre pads are not limited to cutting.
There is no universal wool–microfibre–foam ranking across manufacturers. Products made from the same material can have different correction and finishing goals. A one-step or high-finish claim is not a guarantee that every paint surface will need no further refinement.
Check compatibility, not just colour and size
Colour is a guide within a particular product range. The same colour from a different brand need not indicate the same grade. Check the product name, cutting grade, recommended polisher and compound together.
Distinguish the diameter of the working face from the attachment face and the specified backing plate size. Do not apply one fixed size difference to every pad. Follow the machine's limits and the pad's compatibility chart; centre the pad and attach it securely. Similar names do not establish compatibility between rotary and dual-action applications.
If paint condition is uncertain or the coating is damaged, do not begin with an aggressive combination. A paint thickness reading does not automatically establish a safe number of polishing passes or the remaining correction allowance.
Check a small area first
- Define the goal and inspect the surface. Separate defects you want to reduce from marks you can accept. Check contamination and existing damage first.
- Prepare a compatible system. Match the machine, backing plate, pad and product. Follow the pad and compound instructions for initial priming and subsequent additions; there is no universal number of drops.
- Inspect the result. Remove residue from the test area as directed and assess both defect reduction and finish. Investigate remaining marks instead of repeatedly increasing pressure or speed.
- Stop when condition changes. Stop for excessive heat, deformation, tearing, lifting or insecure attachment. Replace with a clean pad or reassess the combination.
Cleaning, drying and replacement depend on the pad
Accumulated product and residue can make results inconsistent. Inspect the working face rather than relying on a fixed number of panels. Distinguish cleaning during use from washing after use, and follow the permitted brush, pad washer or cleaning method.
Do not use high-pressure water or compressed air on every pad. Even washable products can differ in permitted temperature, detergent and machine washing. Washing wool can alter the fibres and working feel; reassess it before use.
Dry fully using the specified method and store clean. Do not improvise high-temperature drying. Replace a pad with tears, delaminating backing, poor attachment or contamination that cleaning cannot remove. A claimed number of cars is no substitute for inspection.
