Jotun SeaQuantum Ultra S is a state of the art chemically hydrolysing silyl acrylate antifouling coating. It provides excellent fouling protection and incomparable hull performance. This is achieved through highly predictable and stable self polishing characteristics reducing hull deterioration, friction and speed loss. The initial smooth surface provides a very good out of dock performance.
Jotun SeaQuantum Ultra S is a one component state of the art chemically hydrolysing silyl acrylate antifouling coating. It provides excellent fouling protection and incomparable hull performance. This is achieved through highly predictable and stable self polishing characteristics reducing hull deterioration, friction and speed loss.

![]() | Question:
Can I apply the seaquantum ultra S on top of the seaquantum Classic, which I have now? |
Answer from Rawlins’ Technical Team:
Assuming the existing antifouling has been thoroughly high pressure water jetted at 3500psi to remove contaminants, it can be overcoated with Jotun Sea Quantum Ultra S. If that pressure is not possible, the minimum pressure suitable is 2500psi, then the substrate must be lightly abraded prior to application. | |
