Hi I have brown woodgrain windows and want to paint white. do i need to undercoat etc?
Assuming the windows are upvc, you could consider the product below, no undercoat is required, but they must be clean, dry, sound and prepared as detailed in the technical data sheet.
This can be mixed to many RAL, NCS or BS colours in a satin finish.
You will need temperatures of 10°C or more for application and curing.
