Gates and fences face rain and sun, so the paint has to stop corrosion and keep its colour. The quickest option for ferrous metal is ZAKHYST 3 in 1 primer-enamel: it goes straight over rust without a separate primer, dries in 2 hours and protects for over 7 years. The hammer-finish ZAKHYST 3 in 1 gives a textured coat that hides dents and uneven old metal. The classic system is GF-021 anti-corrosion primer followed by DEKOMAL or EXTRAMAL PF-115 alkyd enamel in the colour you need. Galvanised fences are not painted with ZAKHYST 3 in 1: degrease them, prime with GF-021 and finish with PF-115 enamel.
