Hi To all i have a problem with the painting of a piece of timber.i primed and undercoated when i put finish coat on it rained before it had fully dried.I rubbed it down smooth with 120 but when i put the top coat on it looks as though its full of grit but i have tried two tins of paint any help would be appreciated.

Are we talking oil based paint gloss.
If yes, it sounds like it might be miniscule particles of dried paint. They can be virtually impossible to remove as they are still slightly tacky. I normally wait a couple of days and drop down to 220grit and then wash off with white spirit.
I would suggest that you add some terebene to the oil based gloss to speed up the cure time.

Hi yes its leyland black gloss. I did wipe down with white spirit prior to painting,but will give your suggestion a go and let you know how it goes.
Thankyou
Thankyou
i put a small amount of paint on but it bubbles without brushing as soon as it goes on its all oil based paint
Could it be a reaction because of different manufactures paint? Primer and undercoat Dulux Trade finish is leyland black gloss
As you are aware, black gloss will show up all imperfections.
If you can, wait a week or so. Try to sand with a serrated coated silicone carbide sandpaper rather than aluminium oxide. The former has a smaller grit size for the same grit "cutting" value (by that I mean that the grit on 220 is smaller than 220g aluminium oxide).

I don't think that they are bubbles. I suspect that you ripped/shredded the surface when sanding and it is that you are seeing.
I have seen bubbles form when painting black gloss on a bright summer day, they expanded to the size of a lentil and then popped.
Can you post a photo?
Leyland black gloss is pretty thin compared to the Dulux trade black gloss but I very much doubt that is the root of the problem.
