How to buy the best exterior wood paint

When it comes to finding the best exterior wood paint, you'll want to factor in a few things. To make your search less tasking, we've outlined some of the key considerations. And, for the utmost ease, we've also answered some common concerns and burning questions.

The paints and treatments often offer guarantees of several years for their long-lasting protective qualities, for example, the Sandtex 10 Year Exterior Satin (or Gloss), which does exactly what it says on the tin. Generally speaking, most paints specify their guarantees on the side of the tin or in the product descriptions, so be sure to check this before buying.

Mould, mildew and algae
It goes without saying: none of these three things looks good on outdoor furniture, garden fence ideas, shed ideas or other garden structures. Fortunately, many of the products we've picked have you covered. By investing in mould, mildew or algae-resistant paint, you can counteract the effects of damp weather or storage in outside spaces that can leave surfaces looking mottled.

Paint and prime in one 
The fewer the preparative undercoats needed, the quicker the job gets done, so if you're trying to complete a quick weekend makeover project, an all-in-one could be the product for you. Our personal go-to is the Sadolin Superdec Satin Opaque Wood Protection, which is both self-priming and undercoating. Perfect, right? If you're planning on painting garden buildings for your weekend project, our guide on how to paint a shed has lots more tips. 

What paint is best for exterior wood?
For us, our all-time favourite is the Cuprinol Garden Shades Exterior Woodcare, which comes in a trio of sizes and almost guarantees a gorgeous, matt colour. Oh, and it accentuates the wood grain, which adds a chic yet rustic touch. Of course, the real answer to this question totally depends on your preference, so we'd encourage you to explore our list, paying close attention to the unique specifications and charms each product has. Big on colour? Try Johnstone’s Garden Colours. Dealing with the standard brown shed and fence set-up?

Do I need to seal exterior wood before painting?
A good question indeed. First off, let's explain why you might want to seal wood in the first place. Because wood contains natural chemicals that gradually degrade paint, it is often wise to apply sealant in advance. By sealing the wood's pores, the sealant ensures that paint sits atop the surface without being absorbed into the wood. In so doing, problems like warping are avoided. Some products state that sanding and priming to smooth and seal the surface are unnecessary and that the paint has self-priming properties. However, not all do, so be sure to check. For a quality self-sealing option that does not require prior sanding, the Rust-Oleum Garden Furniture Spray Paint is a no-brainer.
