WW2 RN Semtex was a trowelled-on latex-based non-slip composite material. There were originally three manufacturers which may account for the varying colours reported early on.
Semtex on destroyers was actually introduced prior to WW2. It is reported to have been first used on the I class and all new construction after that.
This story has always amused me. George Mack was a seaman gunner who joined HMS Intrepid on her 1st commission in July 1937:
�As soon as we arrived in Chatham our chums began to arrive aboard to see what the new ship looked like, and to renew old acquaintances. From the jetty we looked very smart in our gleaming light grey Med Fleet colours, against the dark grey of the Home Fleet ships that were in the yard with us, but when they stepped aboard things were not so smart. We had managed to sweep up, but the decks looked filthy as they were covered in a new paste-like surface, instead of the brown corticene, held down with shiny brass strips, as on other ships.
By Sunday the POs and leading seaman had gone round other ships to borrow a supply of cleaning materials and we set to with a will to clean the upper deck. To our disgust, nothing had the slightest effect, in spite of all the skills that years of hard-won experience lavished on it! When we eventually met the rest of the flotilla we found they had been equally unsuccessful; the only real difference between the ships was that three had dirty brown decks, three dirty blue decks and three had dirty grey decks!
This curse held over us for about six months, until suddenly we noticed that the Impulsive had cleaner decks than the rest of us. In spite of her trying to keep the secret formula to herself, we soon noticed that she was washing her decks with a salt water hose, and the problem was solved. Salt water and nothing else. We now had the problem of a dirty ship's side! In all fairness however this was one of the best things that happened to destroyers. For it meant there was a really safe foothold in all weathers. Before this the decks were very slippery, and to give extra grip at sea, coconut matting was laid round the guns and along the iron deck, but the first seas coming aboard would rip the lashings, and it was a constant battle to keep it securely lashed down. Another snag about 'Semtex' was that it wore through the soles of shoes at an alarming rate, as it was like walking on sandpaper.�
