Remove carpet tape and carpet adhesive from floors
People love to glue carpet down to the floor. It is all very well but when it come to removing it you are left with a horrid, rough adhesive residue. Be it adhesive or double sided carpet tape. It really has to come off. You need to find out what type of glue it was.
Usually a dark or tan color adhesive is tar based and mineral spirits can be used. Carpet Tape adhesive can be removed with an all-purpose adhesive remover.
A yellow looking substance is generally carpet adhesive and can be lightly scraped or chipped off easily, and an all purpose adhesive remover will work. Once the adhesive is removed, the floor can be sanded with a coarse paper and then re-sanded with finer paper.
WARNING! Adhesive Removers are generally solvent base and are highly Flammable. Make sure all pilot lights and open flames are out, no smoking and LOTS of good ventilation. The fumes are very toxic and breathing them can be hazardous to your health. Before using any sanding or other electrical equipment allow the solvent to dry thoroughly and ventilate the room for at least 24 hours. One spark and you won't have to worry about your floor any more.
Tip: Damp mop the floor with water and a small amount of detergent prior to sanding so as to remove any residual solvent.
