Repairing scratch in veneer fire door

[RobTi]

Hi my daughter had a party and someone decided to scratch graffiti on her beech veneer bathroom fire door, so going down tomorrow with some touch up crayons to see what I can do, question is will I need to lacquer over the repair and with what, I have been searching for a clear lacquer and am a bit lost ?
Thanks

The type of lacquer depends on the composition and finish of the door - and many "beech" fire doors used in student accommodation are simply hot foil wrapped plywood surfaced (i.e plywood with a thin printed paper foil bonded onto the surface). Using wax "pencils" will in any case make it impossible to over-lacquer - because finishes don't adhere to wax. Normally the approach is to soft wax the scratch then buff out the area

Thanks tried the crayons but no luck, looks like a 3-4mm veneer looking at the edges so I think as it’s not seen next to any other doors a full light sand then a varnish

The veneer most certainly won't be 3 to 4mm thick - it will be 0.4 to 0.6mm thick (assuming that it actually is a veneer) with a 3 to 4mm thick plywood substrate. This sort of veneer is notoriously difficult to sand without sanding through to the plywood beneath (which will most probably be a tropical hardwood). Also if the door is 2-pack lacquered (again likely) you may struggle to get any applied finish to adhere and blend seemlessly (you absolutely must degrease the surfaces thoroughly first to remove all traces of oils, grease, cleaning products, silicone, etc). Suggest you take a look at the repair lacquers from Konig UK which are designed for the task (they also sell specialised colouring pens used to disguise scratches) and avoid shop-bought products
