Cleaning and Stain Removal - Concrete Stain?

I had a candle on my patio - It was a candle that had a wax center and coffee beans along the outside. Well i went inside for about 10 minutes and then i came outside and there was this blazing inferno on my concrete slab of a patio. I cleaned up the mess, used all the cleaners i could think of, then used a pressure washer and nothing...What else can i do? I have heard that you can paint the concrete with some sort of a color and grit? Can you get that at the HD and what is it?

Yeah sounds like that may be your only option would be to paint or stain. I would imagine you would end up doing the whole area to match. There are different brands available. I have heard that epoxy based paints are good for concrete, plus they seal at the same time.

Concrete is porous and absorbent. You have a situation where the paraffin has filled the pores. No concrete stains or paint will adhere to the affected area. Power washing will not be effective. You will need repeat applications of solvent cleaner and scrub brush, working from outside stain toward middle to prevent spreading. There are commercial acidic cleaners available. Read and follow product label directions.

I went to Lowe's this weekend and went into the paint aisle and found this Etch-n-clean cleaner for concrete. It said it would clean and prepare the surface. Is this correct? And i found this concrete stain paint there. So would this cleaner work or do I need something else?

The etch in clean cleaner you mentioned contains acids that in theory depending on the product should remove the spot. But it will most likely also lighten the spot making it harder to cover up. In other words the whole area would have to be done.

Really i just want to remove the spot and then just paint........

Etching the surface of the concrete will lighten the area. As it contains acids. Thats the draw back. Most acids can remove stains, when other agents can not but they also cause the whole area to be done. From what it sounds like the cleaner you found is a prep cleaner. Used to prep the area to make sure its super clean prior to painting.

I'm having the same issue, but instead of wax, it was rust i etched out. This left many gray patches verse the tannish color I previously had. Is there any way to restore the color to the uniform tan color or must I paint the area? This is the stairway that leads up to my door. I can't imagine coloring it any other color than natural.

Pretty much you would have to fill the etched area and paint the whole area to match. If you do not fill the etched area it will collect dirt and always look different than the rest of the slab.

The idea of filling is something new to me. What product do I use to fill it with?

There are products called levelers. That are basicly used to fill or level surfaces. If you go to your local home improvement store you should be able to find serveral. Products called quickcrete or similar come to mind. They are easy to use and setup fast. Explain your situation to them if its not that bad you may be able to get away with something smaller.

As indicated, etching of concrete with acid cleaners tends to require that the entire surface be cleaned to keep color and texture consistent. Once clean, seal concrete with penetrating sealer (read and follow label directions for recommended number of coats and required reapplications to maintain) if you desire to maintain the natural color of concrete. Painting of concrete can be done, but moisture issues tend to result in spalling of paint. Thus, the popularity of the new concrete technique of acid etching and staining for a more permanent color finish.
