Roller Covers

Picking the Perfect Paint Roller

There are so many different paint types that choosing the right roller cover may seem like an impossible task, especially for the first-timers out there. But we’ve got some good news in this department, it’s not that hard. The most important aspect is knowing what you want to get out of your project. It’s pretty much smooth sailing from here – at least when it comes to collecting the right equipment. We all know the real fun is just about to begin…

Here are some things you should consider:

Cut from the Right Cloth

All of this can be narrowed down to two main types of paint roller covers – woven and knit models. Woven includes microfibre and mohair rollers. They leave no lint and provide an exceptionally smooth finish. Knit rollers, which are made of polyester and lambswool, are known to hold more paint – that’s also why they are better for covering larger areas. Bear in mind, they do tend to leave some stipple behind.

Have a Nap for Painting

Nap simply means thickness. There are four main choices in this category – short (3 – 5mm), medium (7 – 9mm), long (10 – 15mm) and extra-long (18 – 26mm). The thicker the roller is, the more paint it’s going to hold. Typically, those with the longest nap are designed for rougher surfaces. The shortest nap, on the other hand, holds the least amount of paint, but where it shines is the finish – it’s ultra smooth, especially for water and oil-based gloss and semi-gloss paints. A popular choice for cupboards, doors and similar surfaces. Then, there’s a medium nap – the number one option for feature walls as it also provides a very smooth finish. Finally, the long nap paint roller - works best for ceilings and walls, mostly with flat or low-sheen paints.

Go Wide… Or Don’t

The last decision you have to make is the roller width. In this case, there are three main options. The first is 75 – 100mm. Suitable for minor interior and exterior projects, from fence posts to doors, cupboards and other furniture. The second category covers the ranges from 130mm to 180mm. These roller covers are most frequently used on smaller surfaces inside and outside the house. The largest roller covers start at about 230mm and end at around 270mm. These are naturally used whenever we need to quickly cover a large surface area.

FAQ

Can a paint roller hide wall imperfections?

Yes, absolutely – in fact, that’s what it does best. It’s all about the fit. And the most fitting choices to hide imperfections are either flat or low-sheen paints. But it doesn’t end here – you’ll also need a fitting tool. Lambswool covers with a regular nap will probably perform the best at hiding imperfections, but polyester covers are a good choice also - especially if you’re after a more budget-friendly option.

What’s better – a roller or a brush?

One is not simply a better, updated version of the other. They both have their place in the painter’s collection. A brush does offer more control, which makes it a more flexible option. And a more fitting choice for tasks requiring more finesse and precision. The issue is they require more experience as handling is not that easy for first-timers, hence achieving an even finish can prove quite a difficult task. With more freedom and movement options, there’s also more potential for mistakes. When it comes to holding paint and a greater cover area – rollers are a clear winner. They’re also more beginner-friendly but come at a cost – less manoeuvrability.

What’s an all-purpose roller cover? Isn’t it the best option?

You might find that a lot of brands offer something called an all-purpose cover. What’s the point of having all these different kinds, then? Again, it all circles back to your needs and preferences. For professionals and perfectionists, a one-in-all solution isn’t going to cut it, simply because there are too many surfaces with different requirements. An all-purpose model can do a pretty good job covering them all, but sometimes pretty good - is not good enough. They’re typically the most versatile options that can be easily used in a wide range of applications. It’s a practical and a budget-friendly choice, no doubt.

How do I store my paint rollers between coats?

If you have a short break between coats, you can wrap the roller cover tightly in plastic wrap or aluminium foil to prevent drying. For longer breaks, clean the roller thoroughly, let it dry completely, and store it in its original packaging or a plastic bag to prevent dust and debris buildup.

When should I use a high-density foam roller cover?

High-density foam roller covers are excellent for smooth surfaces and fine finishes. They work well with glossy paints, varnishes, and enamels. Use them for projects like cabinets, doors, or furniture where a smooth, brushstroke-free finish is desired.

Are there specialized roller covers for textured surfaces?

Yes, for textured surfaces like popcorn ceilings or textured walls, consider using a thick nap roller cover (19mm or more). This ensures proper paint coverage in the irregularities of the surface, providing a more even finish.

Can I use the same roller cover for both primer and paint?

While it's possible, it's generally recommended to use separate roller covers for primer and paint. Primer rollers are designed to absorb more and provide better adhesion, ensuring a smooth foundation for the paint.

Are there any accessories or additional tools I need to use along with rollers?

Yes and no. It really does depend on your needs and your project – it’s that simple. If this is a one-time job, a good all-purpose cover might be all you need since there’s no point in spending any more money. But the paint tray is non-negotiable. You simply have to have it – or at least a bucket. Extension poles can save you plenty of time and headache, so if you’re painting a ceiling then yes, it’s essential.
