Good morning, I have a number of both UPVC and wooden windows and doors to paint. They are currently dark brown and I want to change them to anthracite. What product would you recommend and as I will be spraying what thinners, if any, would I need?
Assuming the windows, doors and their previous coatings are clean, dry, sound we can recommend Zinsser Allcoat Exterior Water Based, available in a matt, satin or gloss finish. Any areas of bare or stained timber should be primed with Zinsser Cover Stain. Allcoat Exterior has a huge range of colours - over 4,000 - including Chartwell Green and RAL 7016 Anthracite Grey.
We can also recommend Technispray Kolorbond Aquatek, formulated for brush or spray - its applicable thinners and cleaners are listed at the bottom of the page. Aquatek is available in 2,400+ colours which also include Chartwell Green and RAL 7016 Anthracite Grey.
