Advantages of using a wood paint that is specifically for exterior use
It’s simple: to ascertain as best you can the correct age of the wood.
It's important that exterior wood surfaces have good resistance to UV rays and weathering. Nobody likes sanding, there is no point inflicting such a task upon yourself year on year by using the wrong products.
Wood is a living material that changes over time. Care must be taken to protect it and maintain its quality. Then you can experience the joys of a quality exterior for years.
The fungicidal and insecticidal properties of exterior wood paint is a non-negligible aspect.

The importance of evaluating the substrate before applying the wood paint
Choosing paints specific to exterior woodwork requires a little knowledge of the substrate (the surface being painted).
It would be a shame to spend all that time slapping on the wrong type of paint and then have to start all over again. First, you must identify the nature of the wood.
Has it already been painted?
The answers to these questions will help you narrow down the choice. Once this has been done, and after preparing the substrate, you can move on to choosing a suitable product. Don't forget, you'll find all the info you need in the product descriptions! Choosing the right maintenance products for your wood will ensure the durability of your woodwork!
Exterior wood paints: acrylic
Acrylic paint is water-based and is therefore referred to as microporous. What's the deal with that? Well, it means the paint will let the wood breathe over time. Thus, it will be less susceptible to flaking and water infiltration. Pretty important outdoors!
Acrylic is a popular type of paint, because unlike other paints, it doesn't give off an odour. Neither does it require a specific product to clean it. And yes, you won't need to wash your hands with anything other than water after your DIY session!
Acrylic paint is also highly valued for its low level of VOC (volatile organic compounds) emissions, making it more environmentally friendly. It often has a matte or satin appearance.
Exterior wood paints: oil-based paint
Unlike acrylic paint, oil-based paint, also called glycerol, has an oil base. As a result, it takes longer to dry (about 8 hours per coat).
Exterior wood paints: alkyde paint
Since European directives have begun to impose very low levels of VOC emissions in recent years, a new type of paint has appeared on the market - namely alkyd.
Why choose a stain?
Wood stain is intended to protect wood from mould and insects and prevent greying while leaving the natural grain of the wood visible. It provides microporous, water-repellent protection and doesn't crack.
These days you can get different kinds of stain, tinted or clear. They generally take the name of a type of wood with a qualifying adjective such as golden or aged. Obviously, not all stains have all the qualities listed above. Watch your budget, make sure you read the product descriptions and you're off!
So-called classic stains retain the natural appearance of the wood without altering its colour. Because of this, they are a little less UV resistant. Their resistance is determined by the level of dry residue they contain. A lifespan of over 8 years is feasible with a dry content over 50%. Otherwise, you're looking at 2-5 years.
You should check which product is the best suited to the weather conditions in the region where you're painting. There are even stains designed for extreme climatic conditions such as those found in marine or mountain environments. You can also find anti-parasitic varieties of clear stain. Now you see the importance of a thorough assessment of the substrate!
What's a saturator?
Saturators are used to protect wood from the effects of ageing.
They act against staining and give the wood a satin look without tinting it. Really a saturator is more of a colour enhancer that lets the wood's grain show through!
Saturators are recommended for chalets, decking, fences, etc. Rather than 'painting' it per se, you're covering and protecting the wood!
Exterior wood paints: selection advice
Preferably, go for microporous paints that allow the wood to breathe.
