Description Heavy duty, chemical resistant foundation sealer, it's like a sheet of plastic on your floor The need for BEDROCK Most modern metalised acrylic sealer finishes whilst giving excellent buffability, gloss and scuff resistance fail to provide long term resistance to spillages from food, drink and chemicals found mainly in shopping malls, supermarkets and industrial situations. Adhesion and penetration is another area that normal floor finishes fail to provide maximum performance. This leads to fast wearing in traffic lanes particularly on old floors and terrazzo due to poor penetration and grip into and below the surface.
