Johnstone’s Aqua satin and gloss are known as water-based “trim products”, suitable for interior and exterior timber. Remember Johnstone’s Aqua satin and gloss products do contain a small amount of oil, so water alone will not be enough to clean out of your paintbrush. With its advanced formulation, this paint provides excellent coverage, durability, and a smooth satin finish, enhancing the beauty and longevity of any project. Available in thousands of colours, it covers around 10-12 square metres per litre, depending on the nature and porosity of the painted surface, and will be recoatable in normal conditions in under six hours.

This means, although the paint is primarily water-based, it contains an alkyd (or oil) carrier, so it’s a mix of water and oil! There are only two drawbacks of choosing Aqua Guard over Aqua in my opinion; Johnstone’s Aqua guard cannot be used outside, and it doesn’t come in a gloss finish.The amount of times I have heard a decorator labelling Johnstone’s Aqua satin and gloss as a “brush killer” is unreal. The coverage is great, finish fantastic, no sign of any decrease in the finish being outside, the Paint seems to harden off very well, as you say acts like an out and out oil based paint. I really like the products, but there is a nack to using them, which I’ll explain later in my review.

This isn’t down to the paint being poor quality, but more to do with the decorator not knowing how to apply the product correctly. Johnstone’s Aqua Satin will cover approximately 10-12 square metres per litre depending on the nature and porosity of the surface being painted.

Clean what paint you can from the brush using clean or soapy water, then use one of the three products I’ve just mentioned to finish the job off, dead easy!
