Anotace

This practice covers the repair of rigid cellular polyurethane insulation systems on outdoor service vessels operating within a specified temperature range. Before any repairs are performed, all damaged nonadhering foam should be removed up to the dry, solidly adhering layer and the remaining foam insulation should then be beveled on all sides. If the existing substrate primer is damaged, it should be wire-brushed and reprimed where feasible. To protect the surrounding undamaged area, a covering should be installed around the area that needs to be repaired prior to the application of spray foam. Repairs shall be made in accordance with the prescribed procedure.
