Timber, coated composite and previously painted surfaces do not always take the same preparation. Send product information where available. A coating choice should follow compatibility checks rather than assuming any household paint can be applied over the existing finish.
Handles, hinges and nearby floor surfaces need an agreed protection plan. Explain whether the hardware is delicate or has a specialist function. Removal or refitting of components should be discussed, and no alteration to a certified door assembly is implied.
Rubbing, loose hinges and latch problems should be identified before painting. Extra paint can make tight clearances worse. Suitable hardware repairs can be requested separately, but a new finish is not a substitute for correcting an underlying door movement issue.
The agreed service covers small internal-door painting jobs, compatible surface preparation and agreed finish. Exclusions: Fire/smoke door certification or modifications, exterior coating systems, hazardous paint stripping, door replacement.
