Types of thinners to use
Simon W - 26/5/07 at 02:58 PM

I am planning ahead on what type of treatment I am going to give my chassis. I have decided I am going to give it a coat of red oxide primer following by some hardwearing back industrial floor paint. What type of thinners (synthetic, cellulose etc..) should I be using with oxide primer and something like the below?

Thanks.

Surely arn't you better using the stuff designed for the job? Try this 300082570707

Yeh, undecided on the paint at the moment. So what thinners for red oxide primer?

I use the cheap cellulose 'gunwash' stuff with the red oxide. But Mark would probably give me a slap on the head for doing it!!

( I also use the same stuff for fuel in the grasstracker. 130 octane or thereabouts )

Slap on head duely applied

Celly thinners will break down the binder, making the paint less durable, I am fairly sure you should use turpentine, but white spirit should be ok

What ratio?

How thick is the paint you have bought?

If spraying it (use serious HSE equipment, lead is poisonous!), thin it to about 20secs using a viscosity cup, or to the thickness if single cream is using guessosity job!If brushing it, dont dilute at all, thin it by mixing VERY thoroughly, screwfix do a great electric drill twizzy thing for a few pennies

Are you referring to the red oxide primer containing lead or my chassis paint? I am just going to be using something like the below for respirator:

If its the primer thats the problem then I will just roller the primer on.

Roller the lead, spray the chassis black if you need to, the ebay mask is very marginal, designed for dust and LOW toxic vapour, I would use a gloss roller for it all, you will use about 50% less paint

Thanks for the advice Mark, I will give the mini gloss roller a go!
