I have used water based white trim..two years on still very white, no yellowing. I painted it myself, I did around my free standing cooker in an old fire place I have knocked with pots and pans despite trying not too, it has not chipped, I am very pleasantly surprised as I was told it wasn't as strong as oil based paints. On skirting, doors and trims as well. It was difficult to paint on, took three coats on trims, four on new doors

Thanks for your suggestions everyone....sorry it's not a great photo. The roof is grey. Perhaps we paint the cream parts a warm white and the green either sage green or grey. I agree That the picket fence should be white, just how to tie it in with the rest of the house? Thanks again.

gorgeous pictures. thank you all for your comments. painting is still underway. turned out to be a bigger job than any expected. but its looking good. very white. i have never lived in a white house! i will post pictures when its finished. since you hall have been so helpful though i am going to keep asking your opinion if thats ok. im trying to update. eventually we will renoved kitchen and bathrooms and new carpets. but for now just trying to go slow. atm door all have gold handles...keep them / update? and i have taken the handles off the linen cupboards and wardrobes. i bought 300mm graphite but not sure. any hints? https://www.kethy.com.au/product/pm2810

I’d treat them as skirtings. Def enamel
