looks like she was useing a hair dryer on the grout lines. Is anyone using an aerosol sealer like that? I have seen an installer using something similar. He just sprayed it on and took off. No wiping up excess grout sealer.
Did she say they, (the tile cleaning industry) will shut her down, so you had better hurry to order this?
Wow, they sound like some super, duper, secret agency! If she gets shut down, who else is next! I'm heading for the hills until this blows over, and I'm taking my Turbo with me, if I had one.
By the way Jimmy, thanks for the link,it was verrrrry interesting.
