What Is The Difference Between Curing Time And Drying Time?
Many people don’t realize that there is a difference between curing time and drying time. But there is a significant difference. When talking about paint the drying process comes first, curing happens last. Drying time means that it’s dry to the touch. You will be able to place your hand on the project without leaving any marks, or pulling any of the finish off. Which means the solvent or carrier has evaporated from the coating to form a film. That film can’t be wiped away with gentle pressure. This is the period in which the paint has dried completely, and cured just enough to avoid damage.
Curing time means, the length of time recommended before subjecting your finished project to daily use. Curing occurs when the coat has reached its optimum hardness. Curing can take weeks due to the chemical process. During this process the pigments and binders fuse together into a continuous resilient film. The length of curing time depends on a few different things. The humidity levels in your environment. The indoor temp and the air flow, could all be factors that play into how long it will take to cure. When you are able to wipe or wash the paint surface without damage, and the paint stands up to minor scratches or bumps, then it has fully cured. When curing is complete it’s business as usual.
Our Ekopel drys with in 24 hours. We recommend waiting 36-48 hours to allow the paint to really harden. It can take up to 30-60 days for our Ekopel paint to finish curing. We recommend using your tub after 36-48 hours after application, even though it hasn't finished curing. This is because it won't destroy the finish. It's hard enough that pressure wont effect it. Something that could effect the finish is chemicals from certain shower products. For example chemicals in shampoos, conditioners, soaps etc. Certain chemicals in your shower products could cause the finish to get stained yellowish or the colors of your shower products. If this were to happen to you, we recommend using baking soda and a Mr. Clean eraser. That usually gets the stain out. If this happens to you we also recommend making sure you rinse the shower out when your done. Don't leave any shower product residue in the shower for the next 30 days. This will prevent your tub from getting stained.
Not every product cures the same. For example The Hoover Dam in Nevada still hasn’t finished curing. The Hoover Dam started to be built in 1936 and was finished in 1931. This means the Hoover Dam has been curing for 84 years! Crazy right? It is estimated that it will take The Hoover Dam 125 years to finish curing.
