Per the manufacturer, 50 degrees is bare minimum. It takes a long time for concrete to warm up enough. They would suggest waiting a bit longer until the surface temperatures warm up to at least 55 degrees and that�s after a few days of those warm temperatures before applying sealer. You may order a small sample online to test.
