Hi! Someone told me today the sealant put on marble pavers, in time turns the pavers yellow. Does anyone have any input on this? Doing my research now and I am looking to put marble white pavers. I am concerned about stains, with or without sealant...from leaves or drinks, dog traffic, etc... Also concerned about it being slippery. Any input you can give on how slippery it is or sealant use over time, is greatly appreciated. Thank you in advance!
