stenciled concrete

I'm wanting to put a faux brick border around my new patio and stenciled concrete looks like a way to do it without doing a separate pour that a stamped patio with stained concrete would require.
I've found a website:
http://www.decorative-concrete.net/stencil.php
that details the process and found another website:
http://www.concretesupplyhouse.com/Merchant2/howtocastinplacestencil.php
that sells the goods needed to do the project.
Is this a simpler project than stamped concrete? It appears to be so from a DIY perspective. Does anyone have any thoughts on stamped vs. stenciled concrete? Any advice appreciated.
Thanks.

A stencil is definitely easier than stamped concrete.

I question the durability and color-fastness of any material applied to concrete that is subjected to the weather and sunlight because of the moisture of a concrete slab on grade.

Stamped concrete is usually pigmented with an iron oxide (most durable pigment material available) that is very compatible with concrete/concrete chemistry and is very reisistant to UV.

A stencil on concrete will have a limited life and no depth.

Dick, you are wrong on this one. I do both stamped and stenciled concrete for a living. They are essentially the same product, using all the same materials. The color hardeners used in stenciling are colored with iron oxides and actually make the surface of the concrete much harder than normal concrete. There is a good deal of depth too. I have 3 times had actual brick masons ask me how I layed all those bricks so quickly, and didn't believe me when I told them it was concrete. They now sub a lot of their horizontal work out to me. I am speaking here of stenciling in fresh concrete, not doing an overlay on existing concrete.
While stenciling is easier than stamping, it is not a simple process. One must be proficient at regular concrete work before attempting to tackle decorative concrete. All rules of normal concrete still apply, such as prepwork, mix design, finishing techniques, curing, control joints, etc. Add to that the difficulty of working with color, pattern, and design, and it is typically NOT a homeowner DIY job.
If you would like to see photos of stenciled concrete, you can look at my website www.*****.com I do not post this for advertising purposes, but merely for information.

Pecos,
Say your stenciling a just a border of a patio with a brick pattern, and the rest of the patio will be plain old concrete. Do you do the stenciled part as a separate pour? Or do you have a way of keeping the coloring off the area you don't want to stencil?
Thanks.

Pecos - I was thinking of a different concept. I was thinking of something applied over a new, but existing patio and not new construction with the proper concrete materials.

Pour the concrete as normal, bullfloat and edge it, then place your stencils. Next, put some plastic sheeting down on the portion of the patio that will remain plain gray. Run a push broom over it to stick it down. Don't cover the part you are going to color. When the plastic is stuck down so no color can get under it, apply the color and float it into the surface. Remove your plastic, and broom texture the gray concrete. Last, remove your stencils.
To see the photos on my website, I guess you have to click on my name above, go to my personal profile, and then follow the link. Rules are rules I guess, but it all comes to the same. Good luck.
