Protective coatings were created from commercially available fabricated but also recycled metal powders and commonly available interior paint. The aim of the experiments was to produce protective coatings with different qualitative and quantitative compositions and subsequently test their shielding effects. For the preparation of the coatings, mixtures in the form of commercially produced powder with a particle size of &lt;10 \u03bcm were used, namely aluminum oxide (Al2O3), manganese dioxide (MnO2), and graphite (C). Recycled powders are powdered iron (Fe) and zinc oxide (ZnO) with a particle size of &lt;50 \u03bcm. The powders were mixed in various ratios and compounds into a commercially available white interior paint. Measurements were performed in the frequency range of 0.9\u20139 GHz with a step of 0.1 GHz, evaluating the shielding effectiveness, absorption, and reflection. The best shielding values were achieved for samples containing 100 g of carbon powder, 100 g of iron powder, and 100 g of manganese dioxide, ranging from 0.38 to 6.2 dB in the full measured frequency range.<\/jats:p>","DOI":"10.3390\/ma18163916","type":"journal-article","created":{"date-parts":[[2025,8,21]],"date-time":"2025-08-21T15:19:02Z","timestamp":1755789542000},"page":"3916","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Electromagnetic Field Shielding Using Interior Paints Enhanced with Metal Powders"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4383-3996","authenticated-orcid":false,"given":"J\u00e1n","family":"Zbojovsk\u00fd","sequence":"first","affiliation":[{"name":"Department of Electric Power Engineering, Faculty of Electrical Engineering and Informatics, Technical University of Ko\u0161ice, Letn\u00e1 1\/9, 042 00 Ko\u0161ice-Sever, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8197-6627","authenticated-orcid":false,"given":"Pavol","family":"Liptai","sequence":"additional","affiliation":[{"name":"Institute of Recycling and Environmental Technologies, Faculty of Materials, Metallurgy and Recycling, Technical University of Ko\u0161ice, Letn\u00e1 1\/9, 042 00 Ko\u0161ice-Sever, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2073","DOI":"10.1002\/app.29812","article-title":"EMI Shielding: Methods and Materials\u2014A Review","volume":"112","author":"Geetha","year":"2009","journal-title":"J.
