If you scan any organic textbook you will encounter what appears to be a very large, often intimidating, number of reactions. These are the tools of a chemist, and to use these tools effectively, we must organize them in a sensible manner and look for patterns of reactivity that permit us make plausible predictions.
Oil paints take longer to dry, to recoat and to cure. The first coat will take 12 to 24 hours to dry enough to apply a second coat. Oil paint also cures by binding with oxygen. I have read if you thin your oil paint, you can paint 2 thin layers instead of 1 or 2 thick layers. The thinned paint dries in less time.his isnât the same as it being cured. Latex paint can be painted with a second coat after about 6 hours. It takes about 30 days for the paint to fully cure; meaning that you can wash spots off your wall without damaging your paint finish.
This causes it to have a longer curing time than others. 1  Although times vary based on conditions, most latex paints are dry within one to three hours. 2  A second or third coat can typically be applied within three to five hours. 3  Because latex paint dries on the outside first, it takes at least 14 days for it to cure. If the paint is in an area with bad curing conditions, it could take up to 30 days. Oil Based Paint. Oil paint isnât as popular as it once was, mostly because it takes so long to dry and can take days to get multiple coats on. However, oil paint cures quickly. This is because it dries on the inside first and moves outward. Like latex paint, oil paint varies in dry time, although most oil based paints are dry to the touch in six to eight hours. Second coats can be applied in eight to ten hours, but many people do it the following day. This ensures the paint is dry even when conditions are not perfect.
