This is really off topic, but I thought since several people here are experienced with grout and paints ect, this would be the place to ask. I have searched around on google but didn't find anything really to answer my questions.
We just laid brand new tile in our bathroom and grouted it. I am pleased with how the project turned out overall. Very unpleased with the color of the grout. It is much lighter than the color sample and really just turned out a gray color-should have been a deeper taupe color with a green hue. I would like to change the color of the grout. I found a product made just for this, but they don't have a color available that matches my tile right. After reading through dozens of reviews on several sites, I am inclined to believe this grout 'stain' as it is called, is nothing more than glorified paint. By glorified, I mean it contains mold inhibitors and something to prevent fading of color from UV rays. I found a bottle of it at the local Habitat for Humanity store and read on the label. It is water clean up and dries quickly. I opened the bottle and smelled it and it really did not have any odor. SO. My question is, do you think it would be ok to use a high quality flat finish exterior paint to color my grout lines? I am thinking that would also have the UV protection and the mold inhibitor (which I don't think is necessary unless you were using it IN a shower anyway?). I was thinking of slightly thinning it with water so the pigment would color the grout but would also be absorbed by the grout, not just sit on top like a layer. I plan on using a small art brush to apply it. After this all dries for a day or two, I'd like to seal the grout lines with a regular tile sealer. If I botch this up my husband will KILL me! And this same tile is going to go through the ENTIRE house-one room at a time in a slow motion DIY fashion! I covet any advice.
