I'm looking to sponge paint an accent wall in my living room...Help!

A sea sponge usually works the best. You can get one really cheap at the craft store, also be sure to wet it and ring it out really good before you use it.

Everyone has their own "technique." Here is mine. (1) I use a glazing product, either clear and you tint it, or a color. I used to get it at Lowes. I see they have Valspar Clear Satin Latex Clear Glaze (Actual Net Contents: 16-fl oz) which promises to turn any paint into a glaze. (2) Colors: I tend to use a light wall and a slightly darker version of the same color for glaze. Buy a $2 sample jar of the paint to mix with the glaze (3) Paint the wall the light color and allow to dry (4) plan your time. Stock up a snack, water. Turn off the phone. You MUST do one entire wall at one time, by yourself and without stopping. (5) Get that sea sponge (makes one type pattern) or so as I did and find a polyester corded fabric (bumpy ridges) or other textured (non-cotton) fabric. The sponge is easiest. (6) Do a test card with background color and glaze mixed per instructions on the jar. Wet sponge, wringe out fully. Dab in paint, dab on paper towel so no drips. Dab on wall. Observe your pattern you make with your dabs. I like to make a "V" or a leaf shape, one leaning right, one leaning left, then filling in. (7) Use wide painter's tape to tape ceiling|wall intersection, corner intersection if doing only one wall, and at baseboard. (8) If right handed, start in upper left corner and come down and over. Try to do the same pattern and same kind of dabs over and over. (This is why another person cannot help.) (9) Every once in while stand back and see if the pattern is fairly uniform and filled in enough. (10) Continue until done. (11) make sure you mix every batch of color and glaze base exactly the same. Wash the sponge now and then and wringe out carefully. (12) It is possible to also fill in with a slightly darker shade. Do this after wall dries.

I've done green on green and roasted honey over a slightly more orange-yellow base (yes, it was 2000AD). Do not worry. IF you hate it you can paint over it. Be sure to write down your formula etc. just in case the wall gets damaged and you want to "fix it" months/years later.

This is a fun project. Enjoy.

I love this faux brick technique: http://www.hometalk.com/diy/paint/rooms/a-faux-whitewashed-brick-using-a-kitchen-sponge-paint-19064157?expand_all_questions=1
