Also pFOkUS cleaners must be used to activate the warranty so we know the surface was prepped correctly.

Some states, countries or territories do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty will not extend to any product which has been modified in any way or which has not been used in accordance with pFOkUS’s printed instructions. pFOkUS’s makes no other warranties either expressed or implied. This warranty gives you specific legal rights, and you may have other rights that vary from state to state or from one country/territory to another. This warranty is not transferable.


Surfaces that have a lot of flexibility (resin basin, cultural marble, aluminum, glass and wood) may create a stress crack in the Sentura. Sentura may discolor overtime if Caponi is not applied with or on top of it. Don’t apply when temperature is below 50 degrees.
