How To Paint a Basement Floor



Painting a basement floor requires little preparation work and can give your basement a whole new look.  It will also seal the floor which will make cleaning easier.


Preparation for painting a basement floor 


If your floor has been painted already:



  • Simply clean your floor with TSP (tri-sodium phosphate).  It is a heavy-duty cleaner that will remove dust and dirt from the floor.
If your floor is bare concrete: 
  • You need to etch the floor (open the pores of the concrete) by cleaning it with muriatic acid or a similar solution.  I recommend Clean & Etch by Krud Kutter, as it is easier to use than muriatic acid. 
  • Once the floor is etched, it must be rinsed to deactivate the etching solution.
Choosing not to etch bare concrete before painting can result in premature failure of the paint because it will not bond to the surface as well.
Materials Needed
Paint tray, paint roller, paint brush, extension pole
Basement Floor Painting Tips
Floor painting is very much like wall painting.  It helps to have someone cutting in around the outside of the wall with a paintbrush while the other person is painting with a roller.  Make sure to use an extension pole on the end of the roller frame so you can stand while painting.  
Floor flecks, like used in garages, can also be used in any floor paint.  They must be sprinkled on the floor while the paint is still wet so they will adhere.   
Apply two coats of a good floor paint to achieve the most durable finish.
