3.5.2 Finish Mortar Compound Application Repairs on brickwall bodies and concrete bodies shall be done using concrete repair compound as specified in paragraph 2.1.7 of this specification. All manhole borders and exposed body walls shall be finished using “Finish Mortar Compound” as specified. The application of the products shall be done following the manufacturer recommendations. Special care shall be given to the fact that in most cases, the areas on which mortars have to be applied shall have to be “water saturated”: this is a task frequently ignored. Not doing it properly affects very negatively the final results. The use of ordinary mortar with cement and sand will be limited to those cases where the reconstruction of a brickwall body has to be made. Even in these cases, the finish mortar, border and anchoring will be executed with monocomponent compounds as specified in paragraphs 2.1.7 and 2.1.9 of this specification
