Will laquer stop outdoor colour fading?

Im tempted to buy some self adhesive vinyl brick roll and add it to some surfaces in the garden for a brick effect. The roll itself is either vinyl or pvc I think.

I tried some a sample outdoor last summer and after maybe a month, it had lost all colour and gone greyscale.

If I painted it with clear matt lacquer, would it stop the colour fading? Or do I specifically need some uv anti fading protection coating?

Also, how long does coating typically last, like 2,5,10 years if outdoor?

This caught my eye, but doesn't say about stopping colour fading, or longevity:

There is a clear coat you can apply to plastic car headlights to stop sun making them yellow. That's all I know about UV coatings.

My plastic sign writing on van bonnet only lasted a few years as pointing to sun. The sides lasted 10+ years
 
I am not aware of any clear coating that effectively blocks the UV light from penetrating below the surface.

Exterior coatings are designed to absorb the energy from UV light- they basically distribute the energy across the coating.

Years ago a customer asked me to sand back their cedar decking- it had turned silver. Every coating manufacturer that I contacted warned me that a clear coating will result in the finish going sliver again.
