I'm a Certified installer for Trex decking. Trex Transcend is encapsulated board, with a finish that resists staining, scratches, mold and has a high definition wood grain surface. I don't know what you did to it or whoever worked on your house did something to it, but Transcend decking does not need staining or painting and the protective shell protects decking against fading. Trex Transcend and a few other Trex decking products like Trex Enhance, and Trex Select, they cannot be painted or stained. The only thing can be painted is Trex Transcend White Railings and you should only use light color paint. If you use dark colors, it will absorb heat and it will damage the surface and you can kiss your railings good bye. Also high quality fast drying primer should be used and you have to use Oil or Water based exterior paint and most importantly surface prep is the the key. When it comes to painting specialty surfaces like Trex Railings, hire a Pro to do the work. With that said, if you installed Trex yourself, you have to go to the store and have a Trex representative come out and check your deck. They will determine if loss of color fading was due because of negligence or not. If its a material defect, they will cover the material cost. If you had a Certified contractor do the work, they will cover material and labor. Call your contractor and he will get a Trex Rep to come out within a few days. Good luck

Kretetex makes a concrete sealer "Ghostshield Lithi-Tex L9500". This particular one is Industrail Grade, but their website may have a home grade that might work for you.

Yes they do have similar styles in porcelain, but to me it doesn't look the same. Search around that site and see if any of the other tile designs in other materials strike your fancy. I know you said you don't like the subway, but you could get a glass tile in a 2X8 and lay it in a herringbone or find shorter ones and do a chevron. Don't know if you care for mosaics, or penny rounds, those would also look nice. You are going to have to narrow it down to a look you are drawn to, and then go from there. Search kitchen backsplashes on here to get some ideas as well.
