Radon gas can migrate into buildings from the ground and, to a lesser extent, from building materials such as bricks, granite and concrete. The accumulation of radon indoors can pose a significant health risk, as its inhalation can damage lung tissue, making it the second leading cause of lung cancer after smoking. In 2013, the European Union adopted Directive 2013/59/EURATOM, establishing an average reference level of 300 Bq/m<sup>3</sup> in inhabited areas and the obligation to measure building radon concentrations. In Spain, Royal Decree 732/2019 adapts this directive and establishes specific requirements to protect people from radon exposure. The main mitigation measures include sealing cracks, natural or forced ventilation, sub-slab depressurisation and installing radon barriers. Although current measures are effective, research continues into new solutions to further reduce indoor radon levels. This work focuses on developing an evaluating a methodology for applying a commercially available regular indoor paint to ensure that it can be used as an anti-radon barrier in walls. The results show that a vinyl paint can be used to mitigate radon in indoor spaces reaching a radon concentration reduction percentage of 82.25 %, and a diffusion coefficient of 7.48·10<sup>−11</sup> m<sup>2</sup>/s. The increase in the number of coats is proportional to the effectiveness for radon reduction per unit thickness, with the best results achieved at thicknesses of 90 μm.
