So confused. Trade paint supplier was horrified today when I wanted to buy oil based primer for project in mix of MDF and pine. She said I MUST use a water based acrylic primer as the oil based would make the MDF 'blow'.
But I'd read on kitchen maker forums that they recommend oil primers for MDF and MDF/timber mix, esp when hand painting!
Who's right?
I've used aluminium primer before on a timber/MDF project autumn 2014 as it sealed the knots on the pine and ensured a nice consistent finish across the two substrates. It hasn't 'blown' yet - does that mean it's OK after this amount of time?
My top coat will be traditional oil based eggshell (I bought up discontinued F&B - old formula) and it's in an area of high wear, needs to be tough.
