Painting window boards: gritty surface

Leif

I've been trying to give a final coat of paint on some windowboards without success. Each time I sanded with 380 grade paper. First time I wiped them with a cloth and painted. The surface was like sandpaper, peppered with little gritty bits. Second time I sanded and then wiped them with a meths soaked cloth, and then a dry cloth. Better, but still too many coarse gritty bits. What am I doing wrong? I didn't have this problem when I put the first coats on the window boards over Christmas. I don't think the brush is dirty. Is it something to do with the fine emery cloth?

There are several things that could be giving you trouble.it sounds as if you are cleaning down the paintwork ok.you could get a tack cloth to make sure it is dust free after sanding.you need to make sure your brush is clean.wash it out in turps then wash with hot water and detergent and rinse.also it could be the paint.if it is old or has been kept in a shed then sometimes it has a gritty finish which it sounds like it could be the problem .i would get a new tin-

Thanks nickj. The paint is a few months old, so I will bin it and get a new tin. The brush is kept in a brushmate box, but I will clean it, or maybe even buy a new one as I hate cleaning brushes, and it makes a mess in the sink.

if it's only a few months old it should be fine , however if it's been kept in a shed during the recent freezing weather without protection then that could cause it to go "gritty"
