Shadowclad® Natural can be primed and top coated with all good quality coatings to give a semi-transparent finish. On natural Shadowclad we recommend 1 coat of Dulux Prepcoat 1 Step Oil Based Primer Sealer undercoat, top coated with 2 coats of Dulux Weathershield 100% acrylic water based paints to provide a tough, flexible finish with a 10 year guarantee.
