Pros and Cons of Water-Based Paint

Oil-based gloss, satinwood and eggshell were once the standard paint choice for all interior and exterior woodwork and other trim. However, things are changing dramatically and there is a real shift towards water-based alternatives.

This is happening for two main reasons; governments are restricting the amount of chemicals, known as VOCs, a manufacturer is allowed to use in oil-based paint, thus meaning the paint will not perform as well as it once did. The other major factor is the advance in water-based technology. So, as oil-based diminishes in quality, water-based is getting better.

According to our own research, 75% of Professional Decorator now only use, or mostly use water-based paint for interior woodwork, which tells you all there is to know. The industry is definitely shifting.

The Overall Finish of Water-Based Paints

In my honest opinion, the finish of some water-based paints are lacking compared to their oil-based counterparts. They can appear stringy and have a plastic look, with clear brush and roller marks visible. However, there are some water-based paints which leave you with a flawless finish, but I’ll get to those later on in the blog. It’s just about choosing one of the better products on the market.

Durability of water-based Paints

Durability is another con when it comes to water-based paint. Scuff marks and chips can manifest on your painted surfaces over time, whereas oil-based paints seem to harden and remain easy to wipe down. Again, some of the better water-based paints do not have an issue with durability. I have listed these further down on the blog.

Yellowing of Oil-Based Paint

Remember I said there are now restrictions in the number of VOCs a manufacturer can add to a tin of paint? Well, those VOCs are there to prevent the discolouring of oil-based paint over time. This is due to the alkyd oil used in these products yellowing over time and changing the paint finish. Now VOCs are so tightly restricted, the yellowing of oil-based paint is a real issue, particularly in rooms with little natural light.

Some oil-based brands and products are worse than others. I’ve had real issues with Johnstone’s Trade products yellowing in the past. Oil-based gloss is awfully bad for yellowing due to the amount of oil contained in the paint.

Water-based paints do now yellow at all, so this is a massive pro. It’s also the reason most people make the switch.

Ease of Use

This is something else water-based paint has going for it!! You’ll find water-based is a lot easier to apply than oil. You can use a bigger brush and just lash it on. That said, it can be slightly harder to cut in with it. Most decorators will switch the order they paint a room. Instead of ceiling, walls, woodwork, we opt to complete the woodwork, tape it up, then paint the walls. Thus eliminating the headache of cutting a sharp line around the edges of woodwork such as skirting boards.

Clean up is a lot easier too!! Warm, soapy water is all you need to get your tools clean. Even getting the paint off your skin is no major hardship.

The Environment

Like it or not, oil-based paints are bad for the environment! The waste material and white spirit from the manufacturing process is substantial. Then you have the use of spirits to clean your tools at the end of each decorating job. If you’re environmentally conscious, then water-based paint is the sensible option.

Hybrid Paints – the Compromise Between Water and Oil

We’ve done the pros and cons of water-based paint and as you can tell, there are drawbacks, as well as advantages. However, you could always go for a hybrid paint. These products are primarily water-based; however, they do contain a small amount of oil, which is used as a carrier.

Hybrid paints are the ultimate compromise. In general terms, you’ll find them tougher than water, but not quite as tough as oil. A better finish than water, but not as good as oil. Easier to use than oil, but not as easy as water…. Well, you get the idea!! The list goes on.

Good hybrid paint options include Crown Trade Fastflow and Johnstone’s Aqua

Which are the Best Water-Based Paints?

If you choose one of the products I’m about to mention, I can guarantee you that the pros of using water-based paint will very much outweigh the cons. High-end water-based paint is far superior to anything oil-based in my humble opinion. Durability and finish will be fantastic.

Benjamin Moore Scuff X

This is an awfully expensive product which is shipped in from the US. You’ll find it very easy to use, lays off nicely, the finish is awesome, and it’ll go for miles.

WRX Satin

This is a cheaper option and one of my absolute favourites!! It is slightly harder to hide brush marks when using WRX satinwood, however you’re left with a proper pure brilliant white finish which is to die for!! This is the paint I use in my own home, as well as a lot of my professional decorating jobs. It’s also very durable which helps massively.

Johnstone’s Aqua Guard

The old formula, Johnstone’s Aqua was a hybrid. However, the newer Aqua Guard is fully water-based and is a fantastic satinwood product. You need to use the Aqua undercoat to help aid adhesion and opacity. When you come to use the Aqua Guard, you will find it flows easily, leaves a great finish and remains durable.

Teknos Futura Aqua 90

This is probably the best water-based gloss on the market. It is a hybrid, as most quick-dry gloss products are, but it’s a paint you’ll love. Make sure you use the Futura primer as an undercoat and achieve a solid base before applying the gloss. This paint is tough, durable and looks fantastic.

Best Tools to Apply Water-Based Paint

Water-based paint can be tricky to apply unless you have the right brush and roller for the job, so I thought I’d give my recommendations as part of the blog.

You should opt for a brush that will hold its shape, hold loads of paint, but is soft enough to lay it off and leave a nice finish. My favourite is the Purdy Monarch Elite XL, which you can buy online by clicking here.

As for the roller, the Two Fussy Blokes is widely regarded as the best for water-based paint. Buy the 5mm nap mini-roller. Available online here.

Final Thoughts

OK, I’ve given you the pros and cons of water-based paint. I guess the ultimate test is, what do I use? It has been a long time since I’ve used an oil-based paint inside. I don’t see the point anymore. By using one of the better water-based alternatives, you’ll achieve a great finish in shorter time. Water-based is easier to use, easier to clean-up, better for the environment and will not yellow over time.

FAQs

When not to use water-based paint?

Water-based paint is the best option in most cases. However, sometimes you need an oil-based primer to block stains or adhere to a difficult surface. And sometimes oil-based paints outlast their water-based counterparts when used on exterior wood.

Does water-based paint wash off in the rain?

Once cured, providing you’re using a good quality product, your water-based paint will be waterproof.

What are the side effects of water-based paint fumes?

None really; all paint can smell before it has fully dried, but water-based paint isn’t as bad as oil-based. However, drying water-based paint can raise the humidity in a room, which will in some cases cause you to cough.

Does water-based paint go yellow?

Water-based paint will never go yellow providing the paint underneath it doesn’t yellow either. However, a lot of alkyd emulsion paints (hybrids) are labelled as “water-based”, and they do yellow over time.
