High-Density Open Cell Polyurethane Foam for Paint Rollers, Pads and Sleeves

Choosing the correct roller for a paint job makes all the difference when it comes to the wall finish and the quality of the final outcome. Suitable to use on most interior and exterior walls, foam paint rollers are used to create smooth and even surfaces for new paint finishes with emulsion paints.

Due to their durable and sponge-like consistency, the foam rollers can be used on smooth and uneven surfaces, quickly moving between rooms and wall texture changes.

Why open-cell polyurethane foam?

Open-cell foam quickly absorbs moisture and whilst that might seem like a disadvantage to paint rolling; it actually helps to provide a smoother finish. By absorbing some of the paint into the foam, it slowly releases the liquid with each roll and will evenly dispense paint over walls. Thin paint absorbs well, and varieties like water-based or latex paints are ideal for foam roller usage. Most paint rollers will come with a plastic core that's moisture resistant, maintaining the foam's shape.

Due to its ability to absorb the paint, open-cell foam can take larger volumes of colour than other roller materials such as microfibre. That means that larger surface areas can be tackled without continually dipping the roller in a paint tray.

As its name suggests, the foam has open cells that are specifically created smaller for paint rollers to avoid any air pockets or bubbles when rolled. This denser foam doesn't leave air bubbles behind on walls and maintains an even finish. Polyurethane foam applies paint thinly and leaves fewer lap marks as coats are applied.

Open-cell polyurethane is excellent value for money, and though cheap, the foam itself is high quality and doesn't cause spatter. The quality of foam makes a huge difference when it comes to decoration, and high-quality rollers improve the overall look of the paint and allow for better results in less time. Not to mention the quality of the roller will allow for longevity and reuse. Foam is much easier to clean with warm water under a running tap than microfibre rollers.
