Holmans is closer to the Sikkens which is also an acrylic/polyurethane hybrid, whereas F&B it is an acrylic/alkyd hybrid. I think that Mark Wilkinson is a funny paint in that you can look at it 60 degrees and you would swear it was brushmark free but run your finger over the crossovers and the brush marks are there....it has a specific lustre that is very forgiving. The F&B generally settle out to a nicer finish.
We are a very humid country...I don't think we realise how humid and more often than not we operate on about 70%+. Since paints dry by the evaporation of solvent....if we have a day that has 90% humidity, how can the solvent (water) evaporate?
I am convinced this a humidity problem.
We sprayed F&B the other day....a REALLY heavy coat and it dried *hard*...and I mean hard...in a room that had hardly any air movement and all I can say was that it was really low humidity. We thinned 10%...
