How do I repair scratches and damage on a worktop?

The right repair depends almost entirely on whether the surface is solid through its thickness or a thin decorative layer on a board. Treating laminate like wood is the mistake that turns a small scratch into an obvious bare patch.

Safety

Step by step

1. Identify what the worktop actually is.Look at a cut edge, usually at the sink or the end. Chipboard core with a thin patterned surface is laminate. Uniform colour through the thickness is solid wood, solid surface or stone.
2. Sand and re-oil solid wood.Work along the grain with progressively finer paper, feather the repair well past the damage, then re-oil the whole section until it stops absorbing. Deep damage may need filling with matching sawdust and glue first.
3. Fill laminate rather than sanding it.The pattern is printed and sanding removes it permanently. Use a laminate repair paste or coloured wax filler close to the base colour, press it in, level it off flush and blend the tone with a touch-up pen.
4. Set expectations on laminate.A filled chip on laminate will always be visible at the right angle. The realistic aim is that it stops catching the eye and stops absorbing water, not that it disappears.
5. Treat a laminate scratch differently from a chip.A light surface scratch often improves considerably with a hard wax or a matching touch-up pen alone. Reserve filler for anything that has broken through into the core.
6. Deal with heat marks by material.A pale ring on oiled wood is usually moisture in the finish and often lifts with gentle heat or fine abrasive and re-oiling. A scorch on laminate has melted the surface and can only be filled and disguised.
7. Seal any exposed core immediately.Chipboard swells irreversibly once it takes on water, which turns a chip near a sink into a lifting, bulging edge. Even a temporary bead of clear sealant is better than leaving it open.
8. Buff light marks on solid surface material.Acrylic solid surfaces are the same material all the way through and can be sanded and buffed back to a uniform finish — one of the few materials where a scratch genuinely can be removed.
9. Know when replacement is the answer.Swollen laminate around a sink, or delamination along an edge, cannot be repaired convincingly. Replacing a single run is often less than people assume and is the honest option.

Tips

• Repair kits come in colour ranges. Buy one that lets you mix rather than a single stick, and match in daylight rather than under kitchen lighting.
• Fill slightly proud and level with a plastic scraper rather than trying to fill exactly flush. Overfilling and levelling gives a far cleaner result.
• A chopping board and a trivet prevent essentially all of this. Worktop damage is overwhelmingly knives and hot pans.
