Thread: What the hell?

Let me guess did your SWMBO take hot a shower while the paint was still not set?

Nope, i painted it then went to town for an hour or so. The cornice and upper wall in the robe is the only area affected, The ceiling is fine, the ensuite is fine. (not fitted out so nobody is having showers yet)

Paint not to thin
Plenty ventilation
did you spray it on

Paint straight from can, was not thinned.

I feel the ventilation was adequate, the ceiling is fine.

The paint was brushed on.

Gary to me it looks as tho someone has walked in and sprayed it with a water sprayer

I have seen this once doing my own work/painting but not that bad
found that the paint itself was thin and had to be stirred constantly to stop it sort of seperating.

Looks to me more like you didn't mix the paint up, or not sufficiently, before applying - so what you have applied is a high proportion of the solvent liquid and too little of the pigment.

This can happen easily enough especially when you paint straight from a new tin of paint. Depending how long it has been in the store and or in your garage the solids settle out and although the paint colour looks OK it is actually too thin.

Couple of rules of painting from my dear old uncle Alf (master painter for 60 years):

1. Always stir and mix paint even if it a brand new tin (less stirring is needed of you have just had it tinted and shaken by the tint mixer, but you should still do it each time you are about to open the tin.).
2. Never paint directly from the original tin, but transfer paint to a suitable paint pot. This is to ensure that a) if you knock the pot you spill and lose only the amount in the pot, b) if there is any contamination from the brush or elsewhere it is only on the amount in the pot, c) the original tin is re-sealed immediately so no evaporation occurs or contamination can get to the paint in it, d) you have no risk of dropping the brush into the tin (as the pot you use should only filled with enough to reach to the top of the bristles), and e) when you return any remaining paint to the original tin you can strain it back in through a stocking.

All is not lost - a light sand and a re-coat after ensuring the sealer/ undercoat has been thoroughly mixed and you should be OK.

If my guess about mixing is wrong it might be that the underlying paint had some oily or greasy substance on it that prevented the new paint from sticking - perhaps simply by dint of being an old oil-based finish). Again a light sand should allow you to re-paint without the same effect occurring.

Thanks for the tips. Paint was only in small tin and was stirred before and during painting.

The only time I have seen paint end up like this was when some acrylic paint had been used on material and then left in a shed over night that became very cold and the paint never dried.

i would like to add my experiance with paint drips of some kind.
Maybe abit off topic but ,

i painted our old guttering above our carport once.
About 3 o'clock in the avro.

Anyway, after standing back and thinking " gees Im good", i went inside.
the next morning we had a frost.

The wife went out to take the kids to school and...........................


the white gutter paint had dripped off the gutter and all over the back of the wagon.
If fact it was still dripping.
Like someone had thrown a tin over it.

A wet rag quickly got the paint off and no damage done.
