Sherwin Williams All Purpose Oil Base Primer Dry Time

5 years ago

I am painting kitchen cabinets with an HVLP sprayer and I shot them on Wednesday with an oil base primer with 3 light coats. I was hoping to sand them the next day and when I started sanding it felt gummy. I live in Ohio and it’s during the summer. At the time I had very little ventilation going through the kitchen because I had the windows masked off and no fans. Since then I tore out the plastic in one of the windows and got 2 fans running constantly plus opened up the kitchen to the other rooms that was divided with plastic. Now it’s like a wind tunnel. Tried scuffing today and it seems a little bit drier but still not safe I don’t think to sand. Now it’s been over 40 hrs. The flat panels seem dry but the details like crown and trim still seem a little gummy. Spoke with a pro and said either use shellac base or an oil base primer apparently I had to choose the one that take forever to dry. I’m not a pro by any means.

    Yeah. These are new cabinets. Took care of all the prep work

    Oil primer takes about 8 hours to dry, three coats in a day is too much. The base layer was most likely not dry before you added the second and third coats. Now you have three coats of paint that need to dry. It will take time, as the first and second layers are "trapped" under the final coat.

    Thanks Sherry. Seems like that is the case. Drying but drying slow. First time I’ve worked with an oil based primer. Used lacquer base primer in the past for cabinets and dried quickly and sanded smoothly. Unsure on how well oil based primers sand. I just wished there was less humidity and I think I would be in a little better shape.

    close up the house and run the air conditioning . Personally I would not expect that to be ready for a couple weeks. Not the end of the world. I'm from same general part of the country and have had many inconveniences w paint and surface applications du to weather and conditions. ERR on the side of CAUTION and wait a good number of days.

    Thanks Herb. That’s my next approach. Is to put in my window unit if these fans don’t help.

    Since you put on more coats, too close together, then it will take a much longer drying time. I would give it at least a week, and check again. Keep it well ventilated. I would put in the AC unit too. If not dry in a week, then give it more time.

    Just got help putting in the window unit. Next season it’s central air. Hopefully this will progress the dry time

    @Doug Richardson spoke to my husband (painting contractor for 45 years) and he said to run the AC and check it after a couple of days but because of the number of layers it is going to take at least few days to dry and cure. He said it may feel dry to touch but it won't be okay to sand.

    HU. Yeah never worked with the stuff before. I did use years ago when I brushed on a top coat on a shelf built years ago, and I didn’t like it then. I should have thinned it when I brushed as I look back on it. Stuff is hard as a rock on that shelf. Spoke to another pro painter and he suggested oil base or a shellac and obviously I had to chose the oil base. Never again! It will always be a shellac in the environment I live in.

    Thanks Sherry. I bet he has used oil paints several times in his career. That’s what my intentions are. This week of vacation has been a wash. I was hoping to get this done but I’m not going to rush it. I’ve been remodeling since the beginning of the pandemic so no hurry now. Checked my thermostat it’s 67° and the humidity says it’s about 57.
