Match of Sherwin Williams™ SW9644 Portsmouth *

Custom-matched MyPerfectColor paint made to a selected brand color reference should be chosen carefully before ordering, because these custom color matches are not returnable or refundable. For SW9644 Portsmouth, confirm the Sherwin Williams reference, the product format, the sheen, and the quantity before you place the order.

Plastics vary widely, so it is smart to test SW9644 Portsmouth on the actual plastic part before coating the full item. MyPerfectColor spray paint sticks well to most plastics, but using the MyPerfectColor primer can improve adhesion and reduce the risk of poor bonding on difficult surfaces.

Clean and prep the part for the specific plastic type, then test a small area first if the item is important or highly visible.

For SW9644 Portsmouth, use light, even coats instead of heavy passes. Keep the spray moving, maintain a consistent distance, and overlap each pass slightly so the color builds evenly.

Heavy coats can cause runs, uneven sheen, or a muddy-looking color build. Several light coats usually give better control and a cleaner result on small parts, fixtures, and other spray-friendly items.

Choose the sheen for SW9644 Portsmouth based on how the part will be used and how much reflectivity you want in the finished coating. Sheen affects durability, cleanup, and how the matched color reads on the final item.

A higher-gloss finish will look different from a flatter finish even when the color match is correct, so match the sheen to the application as well as the color reference.

Before spraying SW9644 Portsmouth on metal or over an existing coating, clean the surface well and remove dirt, grease, rust, and other contamination. If the existing coating is glossy, scuffing it can help the new coating bond better.

The condition, gloss, and texture of the old surface can affect how the finished color looks, so do not rely on color match alone when the item already has an older coating.
