Popular Exterior Wood Paint Comparison Guide

Our team at Promain realise that with so much choice available it is hard to decide which exterior wood paint is the best for your situation. Below we will discuss the pro’s and con’s of our 3 most popular outdoor wood paints to help you make the decision.

What is Exterior Wood Paint?

Exterior wood paint is any protective opaque coating that can withstand weathering externally. These paints are formulated to be durable, long lasting and suitable as a weatherproof wood paint. However, exterior wood stains or oils are also options to protect your external wood.

What Is The Best Exterior Wood Paint?

To make it easier for customers we have narrowed down our selection to the three most popular outdoor wood paint solutions:

Now, there is a possibility than all 3 of these products are not suitable for your circumstance. You might have cedar wood which is notoriously difficult to work with, or maybe you are looking for outdoor paint for furniture that is in a coastal environment. Therefore, what’s the best exterior wood paint for you might not be the best exterior wood paint for someone else.

Can you use these exterior wood paint products on other substrates?

It’s a tricky one because on face value you can say yes, Zinsser Allcoat would paint on any of the below substrates directly like the other two products in the list. However, our technical team would not be happy prescribing direct to these substrates for longevity without the primer to aid adhesion first. Therefore, the best Zinsser primer in most of these situations listed is Bulls Eye 123.

You might be asking yourself:

  • Can I use exterior wood paint on masonry?
  • Can you use exterior wood paint on metal?

We would really recommend using a product that is designed for use on those substrates. Why cut corners when a few years down the line the coating might fail? Have a look at our Masonry Paint category here, and our Metal Paints category here. If you need advice call our technical team.

FAQ’s with Exterior Wood Paints

However, if you are asking can you use exterior wood paint on decking, the answer is yes. But, and it is a big but – remember you will more than likely walk on decking. Decking will therefore need a coating that can withstand foot traffic. Have a look at these Decking Paint products for better solutions.

We would really recommend external wood paint like these for application as garden furniture paints, wooden cladding paint, or fence paints. Firstly, always ensure to prepare the substrate correctly first. Remember, you may need a exterior wood primer first.

If you are asking can you use exterior wood paint indoors, you can but make sure you look at the VOC levels. Furthermore, can your family handle a horrendous smell as the paint dries?! It might also be unsuitable because of the use of the internal wood. For example, wooden worktops would be unsuitable for applying exterior wood paint inside on to. As above, just give us a call on 01462 421333 to discuss before making a mistake!
