Wipe your hand across the surface. If chalk appears, do the following:
Wash surface with a mild solution of TSP and water.
Agitate with a stiff brush.
Rinse with clean water.
After the surface has completely dried, rub it with your finger.
If no chalk is evident, surface may be coated.
If chalk residue remains, a surface conditioner should be sued prior to the coating. Consult your paint expert to see which products are recommended.
