There are various benefits associated with applying intumescent coatings both on-site and off-site. For example, with on-site applications there is no need for large or complex spray equipment, and all the steel that needs to be coated is already erected and in place. Finally, on-site application is not a ‘wet-trade’, so construction activities are not delayed while waiting for access to floors.
In comparison, the off-site application of intumescent paint can save time in the construction schedule, as it means that trades do not have to spend days moving through floors and applying paint on-site. After the steel has been erected, there is a shorter window in which applicators are required to be on-site to resolve any damages or spray steel connections. Additional benefits include a reduced number of on-site trades, fewer delays in accessing work sites due to extraneous circumstances, and improved application productivity as time is not spent on moving equipment, personnel or products.
