To refinish a porcelain kitchen sink, first thoroughly clean the surface, and then prepare the surface for application; apply the refinishing product, and wait the necessary time for curing before use. Refinishing products vary, so use a product that is compatible with the sink's material.
The following steps outline how to prepare the surface and refinish a porcelain kitchen sink.
Step 1: Remove fixtures.
Remove the faucet, sprayer, drain ring and any other fixture that is attached to the sink. Thoroughly cut away any leftover caulking to fully expose the porcelain.
Step 2: Clean the surface.
Thoroughly clean the sink by scraping away any soap scum, and use a heavy-duty, acid-based citric cleaner. Then, rinse with water and dry the sink before proceeding to the next step.
Step 3: Prepare the surface for the refinishing agent.
Fill any dents with a fiberglass putty, and use sandpaper to rough up the surface and create an even surface for application. Wipe down the sink with a dry rag before applying the refinishing agent. Some products require the use of a bonding agent before application, so read all of the instructions on the package before application.
Step 4: Apply the refinishing product.
Many refinishing products offer brush-on and spray-on options for ease of use, so apply the agent according to the instructions on the packaging.
Step 5: Allow to cure.
Curing times vary. Typically, the sink should not be used for 3 days. Reattach the fixtures, and reapply caulking after the sink has cured.
Refinishing a porcelain sink is a more economical way to update a kitchen, and a refinishing product offers a simple solution for repair that can be done at home.
