How to Seal Concrete
Do not pour the sealer directly onto the concrete. Use a paint pan.
Apply the sealer with a paint roller in 2 very thin and even coats. Do not apply in straight lines, but rather more like when painting, going back and forth and in different directions, overlapping and smoothing out.
Allow to dry between coats until completely clear, including in any cracks, and no longer sticky. Usually about an hour or two in warm weather and low humidity.
Allow this product to cure for at least 24 to 48 hours before applying wax or traffic, 72 hours or more is recommended. It takes a full 7 days to completely cure in warmer weather and 10 to 14 days in cooler weather.
Minimum application temperature 45 F. Best application temps: 50 F - 90 F.
Avoid applying in extreme heat or direct hot sunlight.
Avoid applying during High Humidity or if rain or fog is expected within 12 hours. Ideal Humidity 50% - 60% or less. Maximum 65%. I'm in a bind and have to get it done absolute maximum 70%.
Clean up tools and spills with warm soapy water before it dries.
Not all surfaces must be sealed if you believe they look better in their natural flat state. Examples would be statuary, retaining walls, and the exterior concrete house slab sides that are exposed. These surfaces require no maintenance. However, if you would like to seal them so as to protect them and bring out the colors more, Clear Shield has a natural satin finish.
