The Ready Seal will hold up fine after using those products.
Most likely, the problem you are experiencing with the Ready Seal is due to not applying enough product.........or maybe you have what I refer to as a "thirsty deck". Usually these are older decks that you see this problem.........they really suck up the sealer..........
I usually tell the customer that this could be a problem if it is an older deck, and that they should expect to have to reseal a bit sooner then usual the first time. I tell them that I have applied two coats, and that is all I can do at this time. I tell them it might need to be done again in a year and a half. Most people understand.
The Ready Seal on my own deck is fading.........my deck is only a year and a half old...........but, I sanded the floor before I applied the Ready Seal........and I only applied one coat.........that's why its fading.
I have been using the product for going on three years now.........each of the few problems I have experienced with it can be explained.
