Can you paint uPVC windows?

Here at Calder Windows, we're big fans of uPVC for window frames.

It's no accident that it's been a staple choice of material for British households since the 80s. It combines toughness, durability, security and energy efficiency with huge aesthetic potential. These days, you can get them in every shade under the sun.

And they're long-lasting. Our range comes with a 10-year warranty as standard – and, if you look after them well, you can expect them to last for upwards of 20 years.

But even a trusty old workhorse can start to sag at the knees eventually. After a while, your once-radiant uPVC frames can start to look, well… a little old and tired.

If this sounds like you, you may be looking for solutions. There are two routes you can go down. The first is to get them replaced by a professional and enjoy that fresh off-the-shelf look. The other is to give them a new lick of paint.

Whichever option you choose, it can be well worth doing – not only for your own sake but also to boost your "kerb appeal" should you come to sell the property.

Things to keep in mind when painting uPVC windows

Whether you have white or wood-effect uPVC frames, it's entirely possible to repaint them. However, before you drive off to the home improvement store, there are a couple of things to take into account.

First, a repainted uPVC frame can look fresh and appealing – but it most likely won't be quite as durable as a newly fitted frame.

And second, it takes work. A surprising amount of work, in fact. It's a bit like doing your own plumbing. If you've got the time, skill set, equipment and inclination, go for it! But if you lack even one of those things, you may find it easier to call in the professionals.

There are paints on the market that have been specifically created for uPVC. This is because you need paint that bonds to the surface. uPVC is tough, sure – but it can still expand and contract in the heat a little. If you don't get the right paint, you can end up with some unappealing textures.

The same goes for any other uPVC object – be it a pipe, gutter, soffit, fascia board, garage door or patio door frame.

Perhaps you've inherited a fading or ageing set of uPVC window frames. Your first port of call is to wash them down with warm water and detergent.

If that doesn't make the difference you desire, you can think about repainting. But remember – if they're nearing the end of their earthly span, it may be more convenient just to get them replaced.

How to paint uPVC window frames

Simple! Just grab a tin of paint and slap it on, right? Well, no.

It takes preparation, elbow grease and a favouring wind – because the weather will contribute to the success or failure of your attempt.

First, you should cover any areas that don't need painting with newspaper held in place by painter's tape.

You need a clean, dry surface to work with, clear of anything that will prevent the paint from fully adhering to the plastic.

That means scraping or brushing off any unwanted bits and bobs with a stiff bristle brush, then degreasing the frame with hot soapy water and a kitchen scourer.

Next up is sanding. With fine grit sandpaper, lightly sand the surface, then brush it and wipe it until it's dry and dust-free.

Before you crack open the tin of paint, you need to apply primer to the frame and dry it according to the manufacturer's instructions.

When painting the frames, you need the right weather for the job. If it's a scorcher, the paint will dry too quickly and end up splodgy or uneven. But if it's a nippy one, the paint won't dry properly.

Your best bet is to get started on a warm, dry day when the paint will set nice and evenly.

You'll need two full top coats. There's a huge range of colours on the market, so make sure to shop around for the right shade for you and your property.

In between coats, you'll want to lightly sand the surfaces. When – and only when – the paint is 100% dry, you want to remove the tape. Any sooner and you'll be left with an uneven line.

Finally, it's worth remembering that paint doesn't harden straight away. Once you've finished the job, leave it to "cure" for a few days.

Frequently asked questions

Should I use a roller or a brush?

If you're painting a window frame, a brush is the easier option. But if you're painting a uPVC door with large flat areas, a foam roller is better.

Can you spray a uPVC frame?

Yes, and this can give you a smooth "factory" look. It's harder than using a brush, however, and requires both practice and space. You'll need to protect areas that don't need painting from the spray.

Can you repaint a dark frame with a lighter colour?

Absolutely. You'll just need a lot of primer.

Can you repaint a brand new uPVC frame?

New uPVC frames are coated with an extra layer of plastic that gives them their showroom shine. Ideally, this shouldn't be painted over for at least 12 months.

Can I use a cheap alternative to uPVC paint?

You can, but it's not advisable. Other types of paint will leave coats that crack, blister and peel – so you'll just have to remove, wash down and repaint them in the long run.

When is it better to buy new?

When it comes to home improvements, DIY is always an option – and aside from anything else, you'll have the satisfaction of having done it yourself.

But if this all sounds like too much work, there's always the option of replacing your uPVC frames altogether.

Durability is one of the best things about uPVC – but if your frames are getting on a bit, slapping on a new coat of paint won't increase their shelf life.

In most situations, you're better off getting an experienced, reputable fitter to replace your uPVC frames in the right hue for you.
