Ps...I should have also mentioned that traditional latex stains were very prone to peeling. It was due to a couple primary reasons. 1) they didnt expand and contract with the wood as well and 2) they were not as permeable and humidity trapped under a deck could literally push the stain off. In the "days" a solid oil may have been a better option than a solid latex.
The new hybrids like the flood product I mentioned doesnt behave that way. In my experience, it is very durable and holds up well to foot traffic, patio furniture, weather etc. It doesn't come off in strips like old school latex. It more less will scuff over time, very much like some of those oul based prodicts that have a less penetrating topical membrane.
If you have a virgin deck, a deck with an oil or even some acrylics. .. stick with oil and sell the customer on it's benefits such as protection from within, ease of maintenance, fade vs scuff, enhancement of woods natural beauty and grain etc.
On those tough to strip decks or ones that have a solid on them already you may want to consider water based as an alternative, one with an oil self priming polymer.
GL!
