HELP!! Paintwork yellowing

betterbargains4u

Hubby has just decorated the lounge and the glossed windowsill has already gone yellow in places!!!
What have we done wrong??

yellowing is usually caused by either the lack of sunlight, heavy exposure to sunlight. moisture, heat or additives in the paint. id suggest stripping it down to bare wood, getting a good quality primer and good quality gloss and start again

I have noticed to my annoyance that white gloss paint ( the non drip kind ) seems to go yellow much quicker than it used to. I have switched to using eggshell finish and it seems to stay whiter longer

I believe there are white paints you can buy now which guarantee not to go yellow. I think Dulux do one and I'm sure B&Q do too!

it could be knots or resin seeping thru paintwork , best to strip back to bare wood , treat knots with knotting solution and prime , u/c and gloss .
paintwork can also yellow with sunlight , use water based paints as they are less likely to do this , also they do not go brittle like solvent based paints

hope this helps
