Homeland Security Secretary Kristi Noem announced Tuesday that the entire southern border wall will be painted black to make it hotter and more difficult to climb.
Noem made the announcement during a visit to a section of the wall in Santa Teresa, New Mexico, crediting President Trump with the idea and personally helping paint a portion of the barrier.
The black paint is designed to absorb more heat in desert temperatures, creating an additional deterrent for those attempting to climb over the wall. Noem also noted that the coating will help prevent rust on the steel structure.
Speaking in front of the steel slats, Noem highlighted the wall’s existing security features, including deep underground foundations to prevent tunneling and significant height to discourage climbing.
Border Patrol Chief Mike Banks confirmed the paint treatment would extend the lifespan of the wall infrastructure. Construction crews are building approximately half a mile of new barrier daily.
The Department of Homeland Security received $46 billion in new funding from Congress this summer to complete border wall construction, part of a broader border security bill.
The painting initiative is part of the Trump administration’s expanded border security efforts, which include deploying military personnel to the southern border and increasing enforcement operations.
Noem emphasized that the administration is investing in multiple security measures beyond the wall, including advanced surveillance technology and waterborne infrastructure. DHS is also focusing on securing the northern border with Canada.
