It takes around 24 hours for ProJoint™ RapidFlow™ to cure for pedestrian traffic, although this time may increase if weather conditions are cooler and wetter. It is advised that freezing temperatures and heavy rain can hinder the curing process, so it can be applied in light rain but dry weather is best. RapidFlow™ should be applied on a permeable sub base, a base with a 5:1 ratio of sand or cement and above is considered to be permeable. The base must be permeable to allow any water collected in the joints to drain, preventing build up as well as stagnant water. As soon as the tub is opened, the exposure to air will start the curing process, to prevent this, any excess material should be stored in the tub, which should then be fully submerged in water. This will cut off the oxygen supply and delay the curing process for up to a month. For general maintenance, it is recommended to sweep the area frequently to remove any debris as this helps to prevent weeds, ProJoint Black Spot and Algae Remover can be used for a more thorough clean. The area may be pressure washed after 30 days using a fan nozzle at a reasonable distance.
