Another question for Craig

Mr Harrison, I am new and about to try your F9 on this stain. I did clean this 1 week before these pictures were taken and the customer is interested in getting this stain out. The only info I could get out of him is that it was from a pot. The stain looks darker than fertilizer but they say there was no iron pot holder. Is it possible that this is a pigment from the pot?. Thank you for the help and I hope these pictures help.i

Hi Randy,

That's definitely rust. I'd use F9 1:1 to start. Use high pressure (65-80 psi) and low volume spray, nice and even. Make sure the surface is dry before you spray it. Do the whole pad and feather the product out just past the control joints. You'll most likely need a double application and go heavier on the rust. Follow all the instructions on the label. Take a look at our videos on www.front9restoration.com and call me if you have any questions regarding application. 855-803-1133
