I need to repaint wood work (skirting boads etc) in my house. I am thinking of using a one coat gloss paint rather than first putting on an undercoat. Does anyone here have experience of this?
You wouldn’t have any problem with white over white. As previously stated, rub down existing paintwork first to get a good key for the new paint it’s also much easier to apply the new paint on surfaces that have been prep’ed first. There is a product on the market called liquid sandpaper which is good for a quick/easy sanding job, but can be a bit messy.
