In the present study, the development of pigmented cement mortar for outdoor applications, aiming to replace traditional finishes, especially in pool settings, was investigated. The study used the properties of workability, particle size, and strength from a commercial sample (CS) as a reference, complying with regulations for pool finishes. In the initial stage, the additive/binder (A/B) and water/cement (W/C) ratios were varied to achieve workability similar to the CS reference. Compression strength and porosity were evaluated as response variables according to ASTM C642 standards at 1, 7, and 28 days of curing. In a subsequent stage, the aggregate/cement ratio was reduced to enhance mechanical performance and reduce porosity. Additionally, colorants were introduced, and compression strength at 1, 7, and 28 days, three-point flexural strength, and the percentage of permeable pores at 28 days were assessed. Pigmented mortars exhibited compressive strengths exceeding 35 MPa, flexural strengths exceeding 5 MPa, and a volume percentage of pores below 8% after 28 days of curing.
