Hi I’m wanting to paint new galvanised corrugated roofing shades in a specific RAL colour; 3028. A UV protective paint would be good too. Can you suggest a suitable product please. NB: the sheets are new
Assuming the galvanised steel roof panels are clean, dry, sound and prepared as detailed in the technical data sheet you could consider the products below.
1 coat of Tikkurila Temadur 20 (mist coat) @ 25um
Followed by 2 coats Tikkurila Temadur 20 @ 50um each
This is available mixed to many RAL, NCS or BS colours including RAL 3028 in a semi-matt finish.
