The Douglas Oxide Mid Grey paint is a high-quality coating for galvanize surfaces. For best results, ensure the surface is thoroughly cleaned and primed before application. We recommend applying our anti-corrosive light grey primer as a first coat. All other surfaces should be clean before application. When using this product, you'll need approximately 1 litre of paint for every 5 square meters of galvanize sheeting to cover. A second coat is recommended, and you'll use less paint on the second coat than on the first. If you're applying with a sprayer, white spirits is the best thinning agent. When using a brush or roller, it's best not to thin out the paint.
