rod Posted November 2, 2007 Share #1 Posted November 2, 2007 I have a question on 2 part primer. How much catalyst do use per oz. of paint? I need to make small batches and could not find the answers on the manufacturers website. Thanks Rod Link to comment Share on other sites More sharing options...

RustyRecycledToy Posted November 2, 2007 Share #3 Posted November 2, 2007 depends on the primer. One of the primers I use are 4:1 ratio, while another is 2:1, while another is 3:1. What specific primer are you referring to? Link to comment Share on other sites More sharing options...

Seein as you got the background... got a question for ya... does one have to be concerned about the cfm delivery capacity of a compressor when using a gravity feed paint gun?

rod Posted November 3, 2007 Author Share #6 Posted November 3, 2007 The primer is Polyprimer high fill. With one quart they gave me an 0.5 oz tube of hardener. I assuned that there would be directions for x many drops per x amount of paint. Any one know? Thanks Rod Link to comment Share on other sites More sharing options...

Thanks Rod I googled it and the mix is 1/2 oz bottle/tube of hardener per 1 quart primer so you'd have to do some calculations for smaller amounts. I didn't see any further instructions on their website. Guess they expect you'd use the whole quart! lol Link to comment Share on other sites More sharing options...
