Q: How Long Does It Take For Coats Of Oil-Based Or Alkyd Paint To Dry?
The majority of alkyd/oil paints, when applied at room temperature, will be dry, set-to-touch, within 6 to 8 hours and may be recoated after 16 hours.However, drying time is really dependent on the specific product and conditions. Poor ventilation, low temperatures, thick films and high humidity will increase these times.
How To Paint : Common Painting Questions
Q: How do I tell if the paint on my walls is latex or alkyd (oil) based?
A: Put some denatured alcohol or fingernail polish remover on a cloth and lightly rub it on an inconspicuous test area.* If the paint softens and is easily removed, then it is a latex paint. If the paint does not really seem to be affected by the test, it is typically an alkyd coating.

How To Paint : Common Painting Questions
Q: Do I need to prime every time I want to freshen my walls with another coat of latex paint?
A: No. Primers are not always needed when repainting.
If you are repainting a similar color, you can lightly scuff sand** to remove the gloss, and clean the surface. Once that is completed, you can simply repaint over the existing latex coating. More than one coat may be needed for uniformity.
Please note that switching sheens, or drastic color changes, may require a primer to minimize the amount of topcoats needed to cover the original color.
