    Sherwin Williams Shurwood precat lacquer

    I got tired of using minwax lacquer for my projects and decided to try something else, hopefully better. I went to sherwin williams and they have a whole line of product finishes for professionals. I asked about lacquers and polyurethanes and the guy gave me a gallon of shurwood precat lacquer to try. I did't have to pay a dime for it. I am about ready to start spraying some tables and was wondering how long I can let precat lacquer sit in the spray gun. I know with nitro lacquer I can basically leave it in the gun practically forever. Do I need to clean out the gun between coats, I will probably do 3 coats they may not be all the same day though.

    Dave,

    From the Sherwin Williams web site:


    SHER-WOODŽ Hi-Bild Pre-Cat Lacquer

    SHER-WOODŽ Hi-Bild PreCat Lacquer is a fast drying, high performance, higher solids precatalyzed lacquer for the kitchen and bath cabinetry and the general wood finishing market. After catalyzation, it provides 4 months pot life as a PreCat lacquer,.

    Don't know if you can use it without catalyst. If you can then I am sure the pot life would be a good bit longer.

    I have the non hi bild, which is 6 month pot life, I was wondering if there would be problems leaving it in the spray gun for a couple days while I am spraying.

    Here's the Product Data Sheet. It says to clean all equipment immediately after use.

    Edit: Larry was posting as I was looking up the PDS. Like him, I have left pre-cat in the gun when I'm spraying multiple items or coats in a day's time. I clean the gun at the end of the day as a precaution.

    I didn't think there would be an issue leaving it in the gun for a few hours or overnight but I thought I would ask first, the guy at sherwin williams didn't seem to know. I would like to try ml cambell but as far as I know nobody around here carries it. I looked on their site for a dealer and the closest was 2 hours or more away. I don't recall seeing a place that sells it online.

    I would rather have a salesman who admits that he doesn't know than a salesman who answers with certainty, except his answer is different than the other salesman's answers, and different than the instructions.

    I have gone to water based finishes, but I have a friend who uses precat lacquer, and leaves it in the gun "indefinitely." As a pro, he is probably spraying something every few days, but he does not empty the gun.

    I want to use water borne. I asked sherwin Williams about water borne and they said it wasn't that good but I couldn't refuse the free gallon. If I remember right Charlie uses target em6000. I think that's what I want to try

    Dave, I used to spray gallons and gallons of SW precat with a 2.5gal pressure pot. I might go a week without spraying and only cleaned the system about every other fillup (and truth be known, I probably missed a few of those) with no problem. I have a pot left over with black lacquer in it, been there for about 3 years now and I just fired it up and shot a small project with it the other day, no problem. Love lacquer. By the way, in case they did not mention, I used to thin mine about 50% for great results.
