Contractor-grade polyester roller covers that actually work for bulk painting projects. The RC1386 12-pack offers 12 covers per pack at approximately 0.88 lb total weight, making it practical for crews handling multiple units or large commercial jobs where you burn through roller covers daily.
At a 3/8 inch (9.5 mm) nap thickness, these hit the sweet spot for semi-smooth surfaces — the bread and butter of most interior painting work. The polyester material works with all paints, stains, latex, oil-based, and primers, eliminating the need to stock different roller types for different paint systems.
Bulk Packaging That Makes Sense
Twelve covers per pack changes the math on painting jobs. The 12-pack format weighs approximately 0.88 lb total — light enough that crews can grab multiple packs without overloading the truck. For contractors running multi-unit apartments or commercial repaints, having a dozen fresh covers means no mid-job supply runs.
The solvent-resistant and water-resistant polypropylene core survives both latex cleanup and mineral spirits without falling apart. That core construction matters when you’re pushing crews to clean and reuse covers between coats instead of tossing them. For oil-based paints, clean with mineral spirits or paint thinner as recommended by the paint manufacturer.
Performance on Semi-Smooth Surfaces
The 3/8-inch nap handles the surfaces contractors paint most — primed drywall, knockdown texture, and previously painted walls. These are designed for semi-smooth surfaces including drywall, plaster, and primed wood. Too thick and you’re leaving texture where you don’t want it. Too thin and you’re making extra passes to get coverage.
Linzer positions this as “Better quality contractor grade” within their polyester lineup. The RC1386 is positioned as a “Better Quality” option within the basic polyester range, offering more durability than economy covers. That translates to covers that hold up through a full room without matting down or losing their nap.

Frequently Asked Questions
What’s the actual coverage per roller? Approximately 10 sq ft per roller (listed in some contexts). Real-world coverage depends on surface texture and paint thickness.
How do these compare to microfiber covers? Microfiber covers pick up and release 50% more paint than standard polyester covers, allowing for faster application. But microfiber costs more per cover. For standard repaints where speed isn’t critical, polyester delivers adequate performance at lower cost.
Should new covers be prepped before use? Some users recommend spinning the roller cover or using tape to remove loose fibers before the first use. Takes thirty seconds and prevents fuzz in your finish.
What about cleanup between coats? For water-based paints, clean with warm soapy water. For oil-based paints, use mineral spirits or paint thinner as recommended by the paint manufacturer. The solvent-resistant core handles both without degrading.
Are there any safety considerations? California Proposition 65 Warning: Product contains di(2-ethylhexyl) phthalate (DEHP), known to cause cancer and reproductive harm. Standard warning for many painting products.
