A few Paint Related Questions!
Posted 03 August 2005 - 02:36 PM
I need to big your brain on issues of PAINT!
just want to confirm a couple of things and ask a couple questions.
First up I got the data sheet for paint I ordered (celly) and it has a mixing ratio of 1000 parts to 600-800 parts
I assume that it's mix it up till it the correct viscosity. and is there anyway i can bodge up a viscocity cup.
a couple of things i didn't understand about the data sheet was a couple of the diagrams
I assume that this is about the gun settings such as set the compressor to 4bars.
but the does the little radius symbol mean? is that somthing to do with the spray apparture(sorry couldn't think of anything else to call it.)
and I have no Idea what this one means
another quick one my primer didn't come with a mixing ratio is there a rule of thumb for mixing primer?
It's Tetrosyl Cellulose EP21 Grey Primer.

for celly, i normaly mix 10 parts paint to 7 parts hardner, for the viscosity cup, the only way is to get one, they are specialy made with a set volume and a set drain hole. the best thing is to spend £8 and use that. when the pics are posted i'll answer the rest of it for you.

Fast thinners for small repairs and panel work , respray thinners , well as the name sugests. differant paint manufacturers paints require differant amounts of thinners to bring to a sprayable viscosity , some are measured by weight , others by volume .
As BMM says you can get a cheap viscosity cup from your local automotive paint suplier and it is best to use one unless you are an experianced paint mixer .

I hava a couple of spare panels to play around with the gun settings and such like but i wouldn't mind just know what the rough mixture parameters are for the primer.
Bristol if you P.M me your e-mail addy I'll send you the diagrams direct maybe we could have a chat on MSN if you have it...don't want to creep you out or anything. :tongue:
I'm gonna e-mail my paint supplier and see if they can send through a data sheet for the primer.
Anyone know where I can Pick up a Viscocity cup from?
Any Links Would be Apreciated!

celly primer is an equal mix 50/50 cant get more simple and it gives a nice application
pic showing spray gun says that you need a 1.2mm-1.4mm nozzle which is standard for most guns so ignore that
And about the pressure if your using a gravity fed gun use 2.5 bar of pressure if you use any more it will be terrible and will ruin the gun 4 bar of pressure should only be used on a suction fed gun (cup below the nozzle)
anu more questions just ask
