How do I match the cement paint on my cool deck?

I patched a long crack on my cool deck today. The crack is gone, however the cement paint that I put over the cement patch is quite a bit darker than the rest of the cool deck. The cool deck is about 20 years old and has faded in the hot AZ sun. The cement paint was supposed to match...it is darker to where you can see the line and a bit glossy. Any ideas how to fix this? I dont want to replace the entire deck, as the rest is in good shape.How do I match the cement paint on my cool deck?
try your paint expert stores-

Then try decorative concrete companies. they apply those types of coatings and should have some good advice.





Lastly try pool companies... they may not handle the deck coating in-house but they may have some recommendations of a sub-contractor of theirs that is familiar with the cool deck brands and other acrylic paints.





Fading of the new paint should happen fast and begin to catch up with the old in a few months of sunny days.How do I match the cement paint on my cool deck?
add a little white paint.test on a piece of scrap wood till you get a match.
