Exterior Paint Color Samples

Last month, I painted a small patch of an exterior wall with a color sample I considered home. I bought the sample from Home Depot. I liked the color and have since purchased and the correct amount of paint from ICI Paints.

Before I apply the paint, I want to make sure the colors match well. I know that the paint darkens (usually) as it dries.

How long do I let the patch HERE new paint dries, which I applied next to the Home Depot paint, to ensure that the colors match?

The can tell you the proper drying time to wait. different paints have different consistencies. Also, if your program is to match the shade sure to paint the same number of layers that you brushed on the small plot.
