So Scaly What you are saying is that a North Wind will dry
paint faster than a south wind?.
Maybe thats why all the changing rooms programs are made
in yhe north east.

If you had the same colour paint in a contolled atmosphere and exposed one to heat and the other to wind.Which would dry first.
You could say heating the paint would cause the atomic structure of the paint to dry due to the atoms accelerating rate.
Wind blowing over the paint would cause evaporation,faster drying using emulsion than oil based.
But this could be argued to the fact the temperature of the wind being in conflict with the heat of the atomic dissruption with the heat drying experiment

Interesting.
But you left out an important part of the elements of the experiment.
The person used as a bench mark for the experiment.
He or she must be able to have a measured threshold(spelling)of bore factore.
E.g. A person of low inteligence might find watching paint dry not as interesting as a person with wider views and opinions of said paint.
Im reading a book at the moment where it cross matches paint drying with watching grass grow.
Some of the experiments are amazing.

For those that have yet to experience the joys of watching paint dry try the link below.

Aye,
A lot depends on the particle size of the pigment used. Wether its above or below 100 microns is quite important.
Some naturally occuring pigments are unable to be reduced to a size below 250 microns, thus giving the paint more surface area, hence it will dry quicker.
So if you want the paint to dry quickly, go for ochres, magnolias etc (sometimes refered to as earth colours).
Man made pigments and analine dyes have a much smaller surface area so the reverse is true.
Whilst were on it, try 'painting' crisps with gloss varnish. You'll be amazed at what you can see!
I have about 20 in my collection now that resemble famous people, including most of the Royal family! All because of gloss varnish to!
Have fun.

The drying times can also be to a certain extent be varied by the techniques of brush strokes used.
A. Stippling.
B. Feathering.
C. Rolling.
To name but three.
I find when painting the first coat of a new colour on canal boats that the side facing into the wind will dry quicker but, the downside to this is that flying insects can cause you to have to sand down the entire surface again. (this in fact can be very rewarding indeed, by varying the fineness of the sandpaper a lot of fun can be had trying to get an even surface) but I digress.
Hiring a drydock is the answer. This way an even drying time is the result for all aspects of the barge. Plus you can use a Spraygun which cuts down the drying time even more. (and it works out cheaper as not as much paint is used) It's just the fun you can have with drying paint, you can have bets with other people as to when the paint will be dry. Also using different types of paint but of the same colour can make for some interesting results.
A friend of mine works for the consumer magazine "Which" testing paint drying times of all the different types available on the open market. He admits that he is becoming a bit of an expert on drying times and gets dead smug whenever bets are placed on which paint will dry first. I have decided to hurl him into the cut next time he tries it on.

What you say about air temperature having an effect on drying times is in fact apocryphal (thanks for that word Sis').
The major factor to affect the drying time of all paints is of course the ambient air humidity.
Let me give you an example,if Artist was to sit in the jungles of equitorial Africa using a basic mixture of Burnt Sienna and Titanium White to capture the subtle hues on the body of a native Pygmy,this paint would take days to dry.
But using the same combination of the aforemention paint,and painting a masterpiece of an Alpaca in its natural setting of the Patagonian mountains
the prevailing dry sub zero winds would dry out the aforementioned masterpiece in a fraction of the time compared to its African counterpart.
I think this is why the wife always makes me decorate the outside of the house in January when a stiff North Easterly wind is blowing.

Your question about the hair dryer is an interesting one,would a pair of misused curling tongs held close to a freshly painted surface have the same effect?.

PS,Just going out into the garden to make sure the grass is growing.

As I was born in the North of England and now live in the South, I can confirm the theory that temperature and wind direction are indeed a factor in the speed at which paint dries. I'm sure there is a marked difference in drying times between Florida, in the USA, and Canada for instance.
However, the very watching of the paint drying has an effect on the drying time in the same way as watching a kettle boil, or waiting to see 'Self Erecting Furniture' work. (Two other good future threads.) It is far better, therefore, to attend to other tasks, and return to the paint surface at intervals to check. As Loz points out, do not use a finger for this purpose. The police have been known to trace the painter by this fingerprint method, and many a graffiti artist is now serving time for making this simple error of judgement.
This subject isn't as simple as it first looks, and Artist is to be congratulated for such a perceptive thread.
Aye, Derek

Actually, I'm rather taken with Artist's words: Stippling, Feathering and Rolling. Sounds more like foreplay than painting to me. Maybe there's more to this palette and brush thing than I'd realized!
Ah Ha, hee hee, get off me woman!
