Spots appearing in paint

**TK1** · 23rd May 2006, 01:31 PM

Hi all,

I have been painting doors and skirting boards lately with gloss enamel white paint (yes, very exciting and modern!).

However, in the bathroom and main bedroom, in a few places at the bottom of doors/door frames, the paint has tended to 'bubble' - it goes on OK but then when drying small spots appear and the paint does not dry here.

I can post pics if it doesn't make sense. Surfaces had been previously painted (many years ago) in enamel and were sanded prior to this coat.

Could it be mould/fungus or damp spots which the paint is not adhering to?

What do I need to do to remedy? All needs another coat so will be sanded, but do I need to treat the surface first now?

Thanks in advance,

Darren

Just guessing here Modelshipright but as you said the problem appears to be near the bottom of doors and frames, could it have been a floor polish/cleaner that has splashed on the surface? Perhaps a light wipe after sanding with a solvent cleaner? or turps prior to painting?

Hi,
Thanks for the replies. Could be cleaning fluid or damp spots. I will give it a sand and wipe with turps/metho and repaint and see how I go.

Regards,
Darren

Hi,

This sissing efffect is caused by a silicone based solvent of some sort!! when painting previously painted surfaces, its always good to do a thorough sanding and to wash all surfaces down with sugar soap.This will minise or eliminate this happening.

If you have finished painting, leave the areas as they are for a couple of days, go back and hit them with a little bit of sandpaper and touch them up

I think this problem is called "fisheyes" and caused by someone spraying "Mr Sheen" or similar silicone based product on the door. Remove as per Dapainters advice or clean door before painting with "wax and grease remover" from a paint shop. Can be a real problem.

Hi,

Thanks for the additional replies. It's been too cold to paint but I'll get back to it soon...will re-sand surfaces and give a good clean with sugar soap or similar, and try painting again. It does look like it's caused by a waxy cleaner or something, and spotting makes me think it may be floor cleaner or similar that got sprayed onto the lower edge of the walls.

Regards,
Darren
