Colour Stabilizing First Coat, Pro Seal 770
Warning, concrete colours will usually fade under normal conditions, Always make sure to have the concrete tested and keep records of the delivery dockets making sure to get the driver to fill out dockets correctly. Dark colours sometimes leech out surfactants (white patchy look) which can get trapped under the clear sealer, DO NOT DO A SAME DAY LAY AND SPRAY WHEN IT COMES TO NEW COLOURED CONCRETE INSTALLATIONS.
Consider weather-related factors and other factors such as shade, areas exposed to direct sunlight, wind, rain, temperature fluctuations, shelter and other factors that can either accelerate, delay or affect the suitable time in which the surface is safe to walk on.
