Retaining wall runs the length of my property on the side of my house going from 2' to about 4' high. As it has been there many years would like to paint or use some product to spruce it us as I just had a concrete walk installed adjacent to it and the wall now really looks bad... please let me know what products can be used... thanks you

Is it wood? Or concrete?

Almost anything can be covered with the right product(paint,stain)

Or built over with new vinyl lattice,and flower beds.

It is a concrete retainer wall

You can pressure wash it(cleaning off the built-up pollution)and paint or stain it to all kinds of colors.
Good luck,let us know which way you go!
