Noe, Are you asking about re-dying the WHOLE carpet? It would seem to me that one would charge a heavy fee for such a service, and the cost / idea of replacement would seem the easier route to go. Have you ever re-dyed a whole carpet ? To do this you would want to strip all of the original color out, and then re-dye. It would seem really difficult to do in my own opinion.
Changing the color of carpet requires some knowledge of how colors combine. It is not like paint that one color covers over another. It is more like putting drops of coloring in a glass of water. The final result is acombination of all the colors that are present. Here are the basic steps. 1) Vacuum carpet thoroughly. 2) Clean the carpet. On some carpets, you may need to clean with a product that will remove the Stain resist coating. 3) Decide on the formula of dye or combination of dyes that will combine with the present carpet color to give the desired final result. 4) Mix enough dye to do the entire job plus a little extra. If you run out, you will never mix another batch exactly the same. 5) With some systems, dye set is added to your dye bath. With other systems, you need to apply the dye set as a separate first step. 6) Spray on your heated dye solution, very hot. This is much like apply prespray. 7) Grrom the carpet to work in the dye evenly. 8) Dwell time 9) Rinse and extract excess dye. Of course you also have to protect walls, baseboards, etc. Since getting an exact color mathc is extremely difficult, most complete dye jobs are done for apartments that turn over. The normal request is to make it a darker shade of brown so that the stains don't show as badly. You will never get the carpet to the shade of green that matches the new drapes or something like that. Also remember that since you are adding colors, you can always go darker, but going to a lighter color won't happen. Also stains are still stains. You may just add some color to them. That is not the same as removing them. Scott Warrington
Scott knows his stuff. First- take the full week long course. Then practice in a place where it does not matter if it is wrong. After doing several wrong, you will get it right. (Maybe) I did this back in 1985, and after several bad outcomes, I got it right. It took a lot of equipment, specifically made for dyeing, and a lot of different colored dyes, which is a big investment. I found the best thing was not changing color, but re-coloring when faded, back to the original color. This worked well for me over almost 20 years, and I did this many times. Many carpets- red, green, brown, or even multicolors fade, and bringing them back or nearly back to original was very lucrative. It saved replacing a carpet when it was not appreciably worn. I would make a separate line on the invoice- after the cleaning line such as- Clean carpet $250, Recolor carpet $150. (Recoloring was about as fast as applying a protector), then after recoloring, I would apply a protector, for another $150 ,for instance. Gary
