SPTA pad-set guide

Choose the set by physical fit and pad role, not by colour alone.

SPTA polishing pad sets can combine different diameters, foam textures, wool pads, face shapes and attachment formats. The useful set is the one that fits your backing plate and covers the cutting, polishing, finishing or waxing stages you actually plan to use.

Pad colours are not a universal industry code. Use the current product listing or the chart supplied with that specific set to identify its pad order. A colour that indicates a firmer pad in one kit may not mean the same thing in another.

Pad face diameter

Confirm the pad's working face and the backing plate it is designed to cover. Similar product titles can hide different measurements.

Backing-plate fit

The attachment diameter and hook-and-loop area must suit the machine setup. “For a 5-inch machine” is not enough detail on its own.

Foam pads

Foam density and face shape influence how a pad behaves, but the set-specific description must define its intended stage.

Wool pads

Wool options are commonly selected for stronger correction work, but they require suitable liquid, technique and finish refinement.

Flat, waffle or shaped faces

Face design changes contact and airflow. Choose it as part of the complete pad-and-product system rather than as a cosmetic preference.

Set composition

Count how many genuinely useful pads and adapters the set contains, including duplicates for pad rotation during a longer job.

Compatibility first

Three matching decisions come before colour or price.

Machine and motion

Check whether the set is described for your dual-action, rotary, random-orbit, drill-adapter or hand-use setup.

Plate and pad dimensions

Confirm the listed backing-plate size, attachment diameter and pad face rather than estimating from the product photo.

Product and pad role

Match compound, polish or finishing product to the intended pad in that exact set.

Paint and defect

Inspect the finish and begin with a conservative test combination. A firmer pad is not automatically the correct answer.

Number of clean pads

Longer work may require several clean pads of the same type so residue and heat do not build up in one pad.

Replacement availability

Check whether you can buy the useful size and grade again without replacing the whole mixed set.

Set comparison

Translate the listing into a usable pad plan.

Listing detail What it helps you decide Common mistake to avoid
Pad and backing-plate measurements Whether the set physically fits and leaves suitable edge coverage. Matching only the nominal machine size.
Set-specific colour or grade chart Which pad the seller assigns to correction, polishing or finishing. Applying a universal colour rule.
Foam, wool, bonnet or adapter content Which stages and tools the kit can genuinely support. Counting every piece as an interchangeable polishing pad.
Quantity per useful grade Whether you can rotate clean pads across a larger vehicle. Expecting one pad to complete a long correction session.

Using and caring for pads

Clean handling improves consistency and makes the set easier to evaluate.

  1. Confirm the set-specific order

    Read the product listing or included chart before assigning a pad to cutting, polishing or finishing.

  2. Centre the pad on the backing plate

    Check that the pad is attached evenly and is not damaged, distorted or contaminated.

  3. Use a small test section

    Start conservatively, inspect the result and increase correction only when the paint and defect justify it.

  4. Keep residue under control

    Clean or change pads as the product and removed residue build up; do not continue with a saturated face.

  5. Clean and dry according to the pad guidance

    Keep used and clean pads separate and allow washed pads to dry fully without distorting the foam or attachment layer.
