A trio of abseiling rope-climbers from Summit Rope Access will top the four 90m iconic masts to power-wash and paint the exterior of the multi-event venue.
The climbers have taken to the ropes as part of the annual mast makeover, scheduled to take six weeks in total, to ensure the stadium is gleaming over Cardiff’s skyline.
The maintenance takes place before Monster Jam roars into town and Wales take on some of the best rugby teams in the world in the 2016 Under Armour Autumn Series.
Principality Stadium Manager Mark Williams said: “We carry out routine maintenance to the stadium’s four giant masts during the summer months, when the weather is dry, to ensure that the venue looks its best for our visitors and the visitors to Cardiff.
“Keeping a venue of this size and stature in excellent condition has to be a year round operation. The majority of this goes on behind-the-scenes on a daily basis with our fantastic in-house team. The mast maintenance attracts more attention as passers-by marvel at the abseilers at work.
“The guys at Summit Rope Access have carried out all high level painting and cleaning for as long as the stadium has been standing and they always do a great job. The next big makeover will be in September when the Terraplas covering is removed after Monster Jam to prepare the pitch for the Under Armour Autumn Series.”
