I have a screened porch. Former owners had dogs so we preferred to remove the indoor/outdoor carpet. When we tried to remove it we discovered it was GLUED down (with carpet glue)...nightmare. Now we are left with what you see. We want to use the porch while we are remodeling; eventually want to put in indoor/outdoor tile. How can we remove glue? Already used chemical remover to get what you see....suggestions?
