Phytatesâwhich are present in whole-grain breads, cereals, legumes, and other foodsâbind zinc and inhibit its absorption [2,12,13]. Thus, the bioavailability of zinc from grains and plant foods is lower than that from animal foods, although many grain- and plant-based foods are still good sources of zinc [2].
Like alkyds, oil-based enamels require six to eight hours to dry to the touch, and you should wait 16 hours or more between coats. Shellac Shellac is sometimes used in faux and special painting techniques.
Cold temperatures may have a reverse effect. The same latex-based paint that requires four hours dry time at 75 degrees Fahrenheit may take six hours or more at 50 degrees. Alkyds and oil-based enamels that take 16 hours to dry at 75 degrees could take as long as 48 hours to dry at 50 degrees. You can use heaters or fans to speed drying by increasing the evaporation rate in cold areas, but avoid painting when it's below 40 degrees Fahrenheit .
