## Summary

Scratch-resistant does not mean scratch-proof. First distinguish a transferred mark from a groove cut into the surface. Cleaning can remove some transferred material, while a deep scratch may need manufacturer-approved repair or replacement.

## Scuff or actual damage?

A rubber or furniture scuff may be a deposit. A visible groove or cut through a cap is material damage. Clean gently before assessing in even daylight; do not scrape with a blade to test depth. Record the location and cause if known. Appearance alone cannot confirm remaining structural capacity.

## Furniture, grit and daily use

Lift heavy furniture instead of dragging it. Use compatible, clean protective feet and check them for trapped grit. Replace broken glides. Consider approved breathable mats, remembering that some backings may stain or trap moisture. Keep work tools and metal filings off the finished deck during nearby repairs.

## Why sanding is not a universal repair

Sanding a capped board can remove its protective finish and create a larger colour mismatch. Some uncapped profiles may allow controlled refinishing under written instructions, but that permission cannot be transferred to another product. Avoid heat guns, flames, solvents and improvised scratch fillers unless specifically approved.

## When replacement is the better option

Deep cuts, sharp edges, damaged fixings or cracking need assessment. A replacement board may differ from surrounding weathered boards even in the same named colour. Confirm batch, orientation and the permitted replacement procedure. Do not reverse a board unless both faces and the fixing arrangement are designed for that use.

## Product instructions come first

Identify the manufacturer, collection, capped or uncapped surface and installation date before choosing a treatment. A method suitable for one composite can damage another. Start with loose-dirt removal, then a small test using the permitted cleaner and a soft non-metal brush. Rinse thoroughly and assess when completely dry. Follow the product's dilution, contact time and care instructions; never mix cleaning chemicals. Restrict access while the surface is wet or unsafe.

## Key points

Scratch-resistant does not mean scratch-proof. First distinguish a transferred mark from a groove cut into the surface. Cleaning can remove some transferred material, while a deep scratch may need manufacturer-approved repair or replacement.

## Comparison

Observation|Recommended response
Surface transfer without a groove|Try approved gentle cleaning
Cut through the cap|Ask for product-specific repair assessment
Sharp edge or cracked board|Restrict access until assessed

## Will scratches fade away?

Some marks may become less noticeable, but disappearance is not guaranteed and damage should not be disguised by aggressive treatment.

## Can I heat a scratch smooth?

Do not use heat as a general repair. It can change the texture, colour and material performance.
