Objectives
1. Develop the ability to observe the work of art, necessary to analyze and prepare diagnoses prior to the intervention;
2. Develop the capacity for graphic, photographic and bibliographic research, as well as complementary means of investigation to support the intervention;
3. Develop the ability to summarize the documentation created during the work through the preparation of a final report similar to the reports required by Decree-Law 140 of 2009;
4. Develop the technical skills necessary to work in the context of conservation and restoration work, applying the acquired knowledge in practice.

5.3. Examples.
6. Concepts:
6.1. Conservation,
6.2. Maintenance,
6.3. Repair,
6.4. Restoration,
6.5. Rehabilitation,
6.6. Reconstruction.
7. Intervention in stone materials:
7.1. sample collection,

8.7. Cleaning using pastes or patches,
8.8. Cleaning using the LASER,
8.9. Disinfestation, higher plants, algae, mosses and lichens.
9. Consolidation:
9.1. Efficacy tests; harmfulness and durability,
9.2. Methods of applying consolidators.
10. Collages:
10.1. structural adhesives,
10.2. non-structural adhesives,
10.3. Reinforcement spikes.
11. Gap filling or microplastering:
11.1. Organic and inorganic binders,
11.2. aggregates,
11.3. The color.
12. Protection:
12.1. Features of water repellents,
12.2. Application techniques.

Practice Component

1. Application of the concepts learned in the Theoretical Component in the context of the work.
2. Creation of a technical report similar to the reports performed in conservation and restoration companies.

Evaluation Methodology
Final Average = PT 40% + PP 60%
PP = DP 40% + RT 60%
PT can be taken in the modalities Attendance/Exam/Special/Student Worker.
PT = Theoretical Part/ PP = Practical Part/ DP = Practical Performance/ RT = Final Report
The values of the Final Average of PP and PT must be equal to or greater than ten values.
