Powder coating and sandblasting in Hong Kong: how prices are set

Updated 5 November 2026

Powder coating and sandblasting in Hong Kong are quoted per job, not from a fixed price list, so the figure depends on your parts. The quickest way to a current price is a request on BlaBlaPrice, where sellers reply with their own offer.

• what exactly is to be treated, and the machining type
• size or coated area in cm or m², and the quantity
• surface condition: rust, old paint or clean metal
• colour, given as a RAL number
• whether parts must be dismantled, and pickup or delivery
• deadline, your city and budget in HK$

Because the price is set per job, two quotes compare fairly only when they describe the same parts, colour and finish. Send the same details to every seller so the offers can be compared line by line.

Why the surface decides the cost

Sandblasting, also called abrasive blasting, cleans and roughens metal to remove rust and corrosion, and the rough surface helps the coating stick. It is the preparation step for almost every coating, so a clean-metal job needs less preparation than a rusted one. Heavily rusted parts need more blasting time, so say in the request whether the parts are rusty, painted or new. Ask whether the workshop blasts before coating or only coats.

Licences and factory registration

A workshop that coats parts for sale should be able to show what it is registered for, and you can ask for proof before you pay a deposit. The government's fees page lists an annual factory registration fee of HK$3,003, and its licensing guide sorts licences by type of business, so ask which ones apply to the workshop you choose.

Pickup, delivery and timing

Name your city among Central, Kowloon, Sha Tin, Tsuen Wan and Tuen Mun, and ask whether the price includes pickup and delivery between your city and the workshop, or whether you bring the parts yourself. Hong Kong's winter runs from December to February and summer from June to August, so for a deadline in those months ask early whether the workshop can keep it.

Post the parts and the deadline as a request on BlaBlaPrice. It is free for buyers: you describe the job in a chat and can add a photo. The AI asks for missing details, looks through sellers' websites and price lists in Hong Kong, and shows what it found. Sellers reply in the chat with price and terms, and your contacts stay hidden until you choose whom to contact. If the parts need machining first, see Turning & milling, or start from the home page.
